Opening the Case

“My legs just gave way.”

“My legs went numb and I don’t understand it.”

If you’ve heard one of those sentences from someone close to you, a parent, a partner, a friend on the other end of a phone call, you know how it lands. Maybe you’ve said one of them yourself. People tend to mention it quietly, halfway through a story about something else. And the worry that follows is real. Was it a stroke? Blood pressure? Something they ate, or didn’t?

Then, sometimes, a blood test comes back with sodium too low. After decades of “cut back on salt,” the whole script flips.

So, is it the salt?

Here’s the honest answer. Maybe. Or maybe it’s the water they’re drinking, a medication, the kidneys, blood sugar, blood pressure dropping when they stand, or something in the spine. That’s the part almost nobody talks about. The whole salt vs. sodium question gets treated like one simple story, and the advice that circulates was written for the average person, not for one particular body on one particular Tuesday.

This isn’t about judgment. It’s about understanding what’s really happening. So we’re going to do what detectives do and refuse to look at a single clue on its own. We’ll separate salt from sodium, look at what the guidelines say and who they were written for, decode what a low sodium result can mean, follow the blood sugar thread that runs through so many of these stories, and work out which other results are worth asking about.

If you’re reading this for someone you care about, or for yourself, you’re probably the one who notices the small things first. It helps to know what to do with them.

One promise before we start. Nothing here is a reason to change the salt in anyone’s kitchen, in either direction. It’s a way to walk into the next appointment with better questions.

Clue #1: Salt vs. Sodium: They Aren’t Twins

Let’s start with the mix-up behind most of the confusion.

Salt is a compound called sodium chloride, and sodium is one of its two parts. By weight, salt is about 40% sodium and 60% chloride. One level teaspoon of salt works out to about 2,300 mg of sodium.

That matters because food labels speak in sodium, in milligrams. Salt is what you hold in your hand. Sodium is the number on the box. To translate, multiply the sodium by about 2.5 and you have the salt.

🔍 DETECTIVE’S NOTE: Quick Translation

Sodium in mg × 2.5 = salt in mg. So, a soup with 800 mg of sodium per serving holds about 2,000 mg (2 g) of salt. One level teaspoon of salt is roughly 2,300 mg of sodium, which is the daily limit most Canadians are asked to stay under.

Sodium also travels under other names. Baking soda (sodium bicarbonate), MSG, and the nitrites in cured deli meats all carry it. Several “sodium” words on one ingredient list usually means the food is saltier than it tastes.

And here’s the piece most people don’t expect: the shaker isn’t the main suspect. About 77% of the sodium Canadians eat comes from commercially processed and prepared foods, while only about 11% is added by the person cooking or eating. Health Canada’s 2017 estimate, based on the national nutrition survey, puts average intake at about 2,760 mg a day, still above the 2,300 mg limit.

What about the fancy salts? Sea salt, kosher salt and Himalayan pink salt carry about the same sodium by weight as table salt. What changes is crystal size, so a teaspoon of a coarse salt can hold less sodium than a teaspoon of fine salt, simply because fewer crystals fit on the spoon. One more detail worth knowing: adding iodine to table salt has been mandatory in Canada since 1949, but pink Himalayan salt isn’t iodized, and sea salts generally aren’t either. If someone has switched over completely, a quiet source of iodine, which the thyroid depends on, may have dropped off the menu.

The label itself gives you a quick read. Health Canada’s rule of thumb is that 5% Daily Value or less is a little, and 15% or more is a lot. Check the serving size first, because every number on the label belongs to that amount, not to the whole package. And if you’ve spotted the nutrition symbol on the front of packaged foods that flags a lot of sodium, it’s the same idea, made easier to see.

Clue #2 — The Poster on the Wall Was Written for the Average, Healthy Person

Now the numbers everyone quotes.

HealthLink BC puts the general guidance this way: aim for about 1,500 mg of sodium a day, stay below 2,300 mg, and go to 2,000 mg or less if you have high blood pressure. Those figures come from the 2019 Dietary Reference Intakes, where 1,500 mg is an “adequate intake” and 2,300 mg is the point above which cutting back is expected to lower chronic disease risk.

Here’s the detail that gets lost. Those reference values were built for apparently healthy people. They make a sensible starting line for a healthy adult. They were never meant to be the plan for someone with heart failure, kidney disease, Parkinson’s, a history of stroke, or a medication list as long as your arm.

So once a medical story enters the picture, the question changes. It stops being “how much sodium is the right amount?” and becomes “how much is right for this person, and why?” That’s a conversation for the person’s care team. What we can do is understand the landscape, so the conversation makes sense.

Clue #3 — Six Health Concerns, Six Different Answers

Same mineral. Very different stories depending on who’s holding the shaker.

High blood pressure. This is where the “cut back” message comes from, and it holds up. Eating too much sodium can raise the risk of high blood pressure and heart disease, which is why lowering it is the standard advice here.

Heart failure. You’d expect tighter to always be better. A Canadian-led trial called SODIUM-HF followed 806 people with heart failure. Half were coached to stay under 1,500 mg a day. After a year, there was no significant difference in deaths, hospitalizations or emergency visits, although the lower-sodium group reported a modest improvement in quality of life. The trial stopped early, so it can’t settle the question. It does show that sodium plans in heart failure are tailored, not one-size-fits-all.

🗂️ FROM THE CASE FILES

The trial’s lead investigator, Dr. Justin Ezekowitz of the University of Alberta, urged patients and their clinicians to keep realistic expectations about what lowering dietary sodium can deliver. (Paraphrased from Healio’s coverage of the SODIUM-HF results.)

After a stroke or mini-stroke. A large trial in rural China, the Salt Substitute and Stroke Study, gave about 21,000 people with a past stroke, or with high blood pressure at 60 or older, either regular salt or a substitute made of roughly 75% regular salt and 25% potassium chloride. The substitute group had fewer strokes, fewer major cardiovascular events and fewer deaths. But the researchers excluded anyone with known kidney disease, and anyone taking potassium supplements or potassium-sparing diuretics. So that result fits some bodies and not others.

Kidney disease. The kidneys are your salt-and-water managers, and they clear potassium too. That’s why potassium-based salt substitutes, which are fine for many people, can turn risky here. One published case report describes a man with kidney and heart conditions who landed in hospital more than once with dangerously high potassium after weeks of using a salt substitute. The same report notes that several common medications, including ACE inhibitors and anti-inflammatory pain relievers, are linked to higher potassium as well.

Low blood sodium. Here the advice can flip, but not always. That’s the next clue.

Low blood pressure when standing. Doctors managing orthostatic hypotension (a drop in blood pressure when you stand up), especially in Parkinson’s, sometimes recommend more salt and fluids, alongside compression garments and specific body movements, all under supervision. That’s the opposite direction from the heart failure conversation, and different again from the low sodium picture.

One mineral. Six situations. No single rule.

Clue #4 — When the Number Runs Low, Salt Isn’t Always the Answer

Low blood sodium is called hyponatremia. It’s defined as a serum sodium below 135 mmol/L, and it turns up in roughly 4% to 11% of older adults.

Here’s what most people don’t know. There are two very different ways to get a low sodium number. One is too little sodium. The other is too much water diluting the sodium that’s already there.

Think of a cup of coffee. Add more water and you haven’t removed any coffee. You’ve just made it weaker. Blood sodium can behave the same way.

So what tips an older body into a low number? Medications are a leading suspect, especially thiazide diuretics and antidepressants. Other common causes are SIAD (a hormone signal that makes the body hold on to water it should release) and endocrine conditions such as thyroid or adrenal problems. Often, several things are stacked together.

Then there’s a cause that has nothing to do with disease. It’s called “tea and toast.” Older adults who find cooking difficult can slowly narrow their meals down to very simple foods, and if they’re also drinking a lot of fluid, the body doesn’t have enough dissolved material (solutes) to help it excrete the extra water. Anyone who has cooked for one after a loss, a divorce, or a move knows how easily dinner shrinks to whatever takes the least effort. It’s human, and it’s worth knowing about.

Why does any of this matter for legs and falls? A Belgian study of 122 patients whose long-standing low sodium had seemed symptom-free, average age 72, found that 21% had come to the emergency department because of a fall, compared with 5% of matched patients with normal sodium. In a smaller group, balance and attention tests improved once sodium was corrected. Low sodium has also been linked with fractures in older adults. These are associations, and the studies are small, but they’ve been echoed often enough to take seriously. Researchers think the reason is that nerve signalling depends on sodium moving across cell membranes, so diluted sodium may slow those signals, though the exact mechanism is still being worked out.

Now the crucial part. The fix depends on the cause. If the problem is too little sodium, more sodium may help. If it’s too much water, the answer may be limiting fluids. For the low-solute type, clinicians often focus on restricting free water and raising solute intake rather than cutting sodium. And whichever way it’s treated, sodium has to come up slowly, because correcting it too fast risks a serious brain complication called osmotic demyelination.

A low sodium result tells you that something is off. It doesn’t tell you which way to push. Too little sodium and too much water can produce the same number, and the plans for each point in opposite directions. That’s why “just add salt” and “just drink more water” are both risky home experiments. This one needs a plan from the doctor.

Clue #5 — When the Legs Give Way, There Are Many Suspects

Legs that buckle, or go numb and heavy when standing, are a symptom with many possible owners. Sodium can be one. It’s rarely the only one.

Blood pressure that drops on standing. Orthostatic hypotension is defined as a fall of at least 20 points in the top number or 10 in the bottom number within three minutes of standing. It’s common in Parkinson’s, with estimates ranging from about one in five people to nearly six in ten. It’s also common in older adults generally, especially with dehydration, varicose veins, anemia, blood pressure medications, or deconditioning. And leg buckling, weakness, and foggy thinking can all be part of the picture.

Medications. Blood pressure pills and diuretics are the obvious ones. In Parkinson’s, the same review notes that drugs, heat, big meals and alcohol can all bring on or worsen a drop in pressure. Timing matters, so it’s worth noticing whether the legs go after a dose or after a meal.

The spine. Lumbar spinal stenosis, a narrowing of the canal that houses the nerves in the lower back, causes a pattern called neurogenic claudication: leg numbness, heaviness or weakness that builds with standing or walking and eases with sitting or bending forward. Ever seen someone lean on a shopping cart for relief? That’s the classic clue.

Circulation and nerves. Narrowed leg arteries can cause cramping and heaviness with walking, and doctors often need to tell that apart from the spine. Low vitamin B12 can cause tingling, numbness and nerve damage that may be irreversible if it goes untreated. Diabetes can injure nerves too, and we’ll come to that shortly.

The heart and the brain. After a heart attack and mini-strokes, doctors keep a close eye on rhythm and blood flow. Sudden numbness or weakness on one side, or sudden trouble walking, isn’t a nutrition question at all. That’s a call to 9-1-1.

Sodium and fluid balance. Low sodium, or being low on fluid volume, can add to unsteadiness and to a drop in pressure on standing.

So when someone’s legs go heavy and numb, sodium could be part of the story. It could equally be the spine, the circulation, blood pressure on standing, or a medication.

Nobody can sort this out from a kitchen table, but a good description gets a doctor most of the way there. Three details are worth writing down: what was happening (standing still, walking, getting up, after a meal or a dose), what made it better (sitting, leaning forward, lying down), and whether it hit one leg or both. A sentence like “it only happens when I stand a long time, and sitting fixes it” is a wonderful clue to hand over.

There’s one more thread that runs through almost every suspect on that list, and it’s the one people forget to mention at appointments: blood sugar.

Clue #6 — The Blood Sugar Thread: Where Diabetes Fits

If diabetes or prediabetes is in the picture, several suspects from the last clue become more likely, and a few new ones join the line-up. This isn’t about blame. It’s about knowing which questions to ask, because blood sugar touches sodium, legs and balance in at least five different ways.

High blood sugar can make sodium look low. Glucose in the bloodstream draws water into the blood, which dilutes sodium. It’s a well-known effect that lowers the measured sodium, and doctors adjust for it when they read the result. If sugar runs high enough that the kidneys spill it into the urine, water, sodium and potassium go with it. So someone can be diluted and dry at the same time, which is a recipe for dizziness on standing.

Low blood sugar can make the legs go weak. Hypoglycemia means a blood sugar below 4.0 mmol/L, and it can bring sweating, shakiness and dizziness at first, then weakness, confusion and a “fuzzy head.” It’s caused mainly by insulin and insulin-boosting pills such as sulfonylureas, and skipped meals, extra exercise or alcohol can tip it over. Older adults may miss the early warning signs, and in people over 65, sulfonylureas carry about a 50% higher risk of low blood sugar, which has been linked to dizziness and falls. So when the sentence is “my legs just gave way” and the person takes one of these medications, the first check is simple: what was the blood sugar at that moment?

🗂️ FROM THE CASE FILES

Diabetes Canada’s hypoglycemia guideline makes a simple point: it is safer and more effective to prevent a low than to treat one after it happens. That means people at higher risk should be identified and counselled, along with the people around them. (Paraphrased from the Hypoglycemia chapter of Diabetes Canada’s Clinical Practice Guidelines.)

Nerve damage can produce both of our opening sentences. Over time, high blood sugar can injure nerves, most often in the legs and feet. Diabetes Québec lists the signs as numbness, tingling, throbbing, a sensation of walking on cotton wool, cramps and muscle weakness. The Mayo Clinic notes it may affect as many as half of people with diabetes. The nerves that run automatic functions can be involved too, which can mean blood pressure drops on standing and less awareness of low blood sugar. A doctor or foot care specialist can check for it in minutes, using a thin nylon filament and a tuning fork on the big toe.

Some diabetes medications can dry you out. The SGLT2 inhibitors (empagliflozin, dapagliflozin and canagliflozin) lower blood sugar by sending glucose out in the urine, and Diabetes Canada’s patient sheet lists low blood pressure among the possible side effects. Canadian “sick day” guidance also names the medications that may need pausing when vomiting, diarrhea, fever or poor fluid intake dry the body out: metformin, the SGLT2 inhibitors, ACE inhibitors, ARBs, diuretics and anti-inflammatory pain relievers. The rule of thumb is to phone the pharmacist or doctor on a dehydrating day, rather than deciding alone.

The kidneys sit in the middle of it all. Diabetes can damage them quietly, so Diabetes Canada recommends kidney screening with an eGFR blood test and a urine albumin-to-creatinine ratio (ACR), starting at diagnosis in type 2 diabetes and repeated every year. Kidney function shapes how the body handles sodium and potassium, and how long some diabetes medications linger. The same guidance recommends ACE inhibitor or ARB-type medications for many adults with diabetes and kidney disease, which is exactly why potassium salt substitutes need a doctor’s go-ahead (Clue #3). And kidney disease in diabetes counts as a marker of higher cardiovascular risk, one more reason the sodium, sugar and kidney results belong on the same page.

Blood sugar rarely acts alone. A glucose reading, a sodium reading and a kidney reading tell a far better story together than any one of them does on its own.

Clue #7 — One Number Is Never the Whole Story

Here’s what your blood work is really doing. A low sodium result tells the doctor that it’s low, and how low. It doesn’t tell them why. That comes from a handful of other results, plus how the person looks and feels. The usual first step is working out whether the body is dry, balanced or overloaded with fluid, then narrowing down the cause.

Interpreting all of that is the doctor’s job. But knowing what’s on the list means you can follow along and ask good questions. Here’s the list, grouped by what each test tells you.

Salt and water balance. Serum sodium, of course. Then serum osmolality and urine osmolality, which measure how concentrated the blood and the urine are. Comparing them helps separate a “too much water” problem from a “too little sodium” one. Urine sodium shows whether the body is clinging to sodium or letting it go, and it’s often the tie-breaker.

Kidney function. Creatinine, eGFR (an estimate of how well the kidneys filter) and urea. The kidneys steer salt, water and potassium, so this result shapes both the cause and what’s safe to do about it. With diabetes, a urine albumin-to-creatinine ratio (ACR) joins the list, because it can flag kidney changes early.

Potassium, magnesium and the other electrolytes. Potassium, chloride and bicarbonate usually come on the same panel as sodium. Magnesium and calcium often don’t, so it’s fair to ask whether they were included. Potassium that’s too high or too low changes muscle strength and heart rhythm.

Hormones. TSH (thyroid-stimulating hormone), and sometimes a morning cortisol. An underactive thyroid or an adrenal problem can quietly lower sodium.

Blood sugar. Glucose, and HbA1c (your average over roughly three months) if diabetes is in the picture. Sugar that runs high can make sodium look lower than it truly is, and repeated lows are worth knowing about, so bring meter or sensor readings if you have them.

Blood, iron and nerves. A complete blood count (CBC) to look for anemia, which can add to dizziness on standing. Ferritin for iron stores. Vitamin B12, with methylmalonic acid or homocysteine (both markers of B12 deficiency) added when the B12 number is borderline. And 25-hydroxyvitamin D for bone health, which matters when falls are the worry.

The heart. An ECG (a tracing of the heart’s rhythm) is part of the standard first-round checks when blood pressure on standing is in question, alongside the blood count, metabolic panel, thyroid and B12.

And two “tests” that aren’t blood work at all. The first is blood pressure and pulse lying down, then again after standing for about three minutes. For someone whose legs give way, this may be the most revealing measurement of all, and it costs nothing. The second is a foot and nerve check with a thin nylon filament, which matters if there’s diabetes or numbness in the feet.

A few habits make results easier to read. Ask for the actual numbers and the lab’s reference range, not just “it’s fine.” Look at the trend across several tests instead of one snapshot. And remember that “in range” isn’t the same as “feels right for you.” If results look normal but the symptoms are real, say so plainly and ask what else could be behind it.

Clue #8 — Walking Into the Appointment Prepared

Appointments are short. A little groundwork makes them count.

Bring a full list of everything taken. Prescriptions, over-the-counter pills, supplements, antacids and acid reducers, pain relievers, sleep aids. If there’s diabetes, add the glucose meter or sensor readings and note any lows. Pharmacists are the medication detectives here. In B.C., 8-1-1 can connect you with a pharmacist for medication questions outside regular store hours.

Keep a simple one- or two-week log. What was eaten and drunk, roughly how much fluid, any salty or very simple meals, and when the dizziness or leg symptoms happened. Note the pattern: on standing, after meals, first thing in the morning, after a dose. If there’s diabetes, jot down the blood sugar reading from the moment the legs went funny. If there’s a home blood pressure cuff, add a lying and a standing reading.

Questions for the doctor:

• Why is the sodium low: a salt issue, a fluid issue, or something else?
• How are the kidneys doing, and does that change what should be eaten or drunk?
• Could any medication be contributing, including diabetes medications that can cause lows or dry the body out?
• Should salt or fluids go up, down, or stay the same, and by roughly how much?
• Can blood pressure be checked lying and standing?
• When were the last kidney (eGFR and ACR) and foot checks?
• What should we watch for, and when should we call?

Questions for the pharmacist:

• Do any of these medications lower sodium, lower blood pressure on standing, or raise potassium?
• Does the timing of doses matter?
• Which of my medications are on the sick-day list, and what should I do on a day I can’t keep fluids down?
• Is a salt substitute safe with this combination?

And one steady rule: no big swings at home. Sodium and fluid changes belong on a supervised, gradual plan.

🔍 DETECTIVE’S NOTE: 

Notice what just happened across this whole case. One set of advice said less. Another said more. A third said it depends. And blood sugar turned up in almost every chapter. When guidance seems to contradict itself, that’s usually a clue that the question is missing a detail: which body, which cause, which medications.

My job here isn’t to tell anyone how much salt to eat. It’s to help you spot when a single headline is being stretched over a body it wasn’t written for, and to help you carry better questions to the people who can see the full chart. Some of the studies in this article are associations, not proof of cause, and I’ve tried to keep that line clear.

Nutritional Support

Food first, always. Sodium targets belong to the care team, so nothing below tells anyone how much salt to use. This is about the nutrients standing next to sodium in the story.

Steady, real meals. Protein at each meal gives the body the dissolved material it needs to handle water: eggs, fish, poultry, beans and lentils, yogurt, cheese. If cooking for one has lost its charm, batch a soup or stew and freeze single portions. It’s the easiest way to keep “tea and toast” from becoming the whole menu. Pairing carbohydrates with protein and fibre also helps keep blood sugar steadier through the day. If you take insulin or a sulfonylurea, skipped or delayed meals are a low blood sugar risk, so keep to the meal pattern your diabetes team recommends. And if sodium is low, ask the doctor how salty those meals should be.

Potassium from food, not pills. Sodium sits mostly outside your cells and potassium mostly inside. Together they carry the electrical signals that fire your nerves and muscles, your heart included, and they manage water balance. Leafy greens, beans and lentils, potatoes with the skin, tomatoes, bananas, oranges and yogurt are all good sources. The caution is about concentrated sources. With kidney disease, or medications such as ACE inhibitors, ARBs or spironolactone, potassium salt substitutes and potassium supplements can push levels dangerously high, so they need a doctor’s go-ahead first.

Magnesium. It supports muscle and nerve function, and some diuretics can lower it. Pumpkin seeds, almonds, cashews, black beans, spinach and whole grains are the everyday sources. If a practitioner suggests a supplement, magnesium glycinate is a gentle, well-absorbed form. Kidneys clear magnesium, so check with a pharmacist first if kidney function is reduced.

Vitamin B12. It comes from animal foods: fish, eggs, dairy, meat and poultry. Older adults absorb it less well, and metformin and other medications can interfere further. The adult requirement is 2.4 mcg a day, but treatment for a confirmed shortfall works differently and is set by the provider. Test first. If it’s low, methylcobalamin or adenosylcobalamin are the active forms to ask about, instead of the synthetic cyanocobalamin.

Vitamin D, fat and magnesium. When falls happen, bone strength matters. Vitamin D is fat-soluble, so D3 (cholecalciferol) is best taken with a meal that contains some fat, and magnesium helps the body switch it on. Check the 25-hydroxyvitamin D result before choosing a dose.

Supplements are the second step, and they work best when a practitioner is guiding them. The first step is always the plate.

Red Flags: When Salt Isn’t the Whole Story

Some things shouldn’t wait for a food diary.

• Sudden numbness or weakness on one side, a drooping face, slurred speech, or sudden trouble walking or balancing. Call 9-1-1 immediately, even if it passes. Heart & Stroke’s FAST reminder covers face, arms, speech and time. After previous mini-strokes, this matters even more.
• New confusion, unusual drowsiness, a severe headache with nausea or vomiting, a seizure, or a collapse. These can signal a serious sodium problem or another emergency. Call 9-1-1.
• Fainting, chest pain, palpitations, or breathlessness. Emergency care.
• Sudden weak legs with sweating, shakiness or confusion in someone taking insulin or a sulfonylurea. Check the blood sugar right away. Below 4.0 mmol/L is low, and the BC guideline for treating it starts with a fast-acting sugar, then a recheck in 15 minutes. If the person is unconscious or can’t swallow, call 9-1-1.
• A fall with a blow to the head, painful or shallow breathing after a rib injury, or being unable to put weight on a leg. Get assessed promptly. Rib pain that limits deep breaths can lead to chest infection.
• Leg weakness with new loss of bladder or bowel control. That’s a spinal emergency, and severe stenosis can bring progressive weakness and incontinence.
• Vomiting, diarrhea, fever, or being unable to keep fluids down while taking any medication from the sick-day list. Call the pharmacist or doctor the same day.
• A blister, sore or wound on the feet that can’t be felt. Loss of feeling in the feet raises the risk of ulcers, so it needs a prompt look.
• New unsteadiness, confusion or dizziness after starting a diuretic or antidepressant. Thiazide-related low sodium most often appears in the first few weeks, but can show up months or years in. Call the pharmacist or doctor.
• Repeated falls, dizziness on standing, or fatigue when the results say “fine.” Ask about the tests from Clue #7: serum sodium with urine sodium and osmolality, creatinine and eGFR (plus a urine ACR if there’s diabetes), potassium and magnesium, TSH, glucose or HbA1c, a blood count with ferritin, vitamin B12, 25-hydroxyvitamin D, an ECG, and lying-to-standing blood pressure.

A bodily signal is sometimes a memo, not a diet problem. If the clues don’t add up, the next step is a proper investigation with someone who can order the right tests.

Closing the Case

So, back to those two sentences.

“My legs just gave way” might turn out to be low sodium, a blood pressure that drops on standing, a low blood sugar, a medication effect, or a mix. Which one it is decides whether the plan adds sodium, eases fluids, adjusts a prescription, or does all three. And it should be steered by the people who can see the kidneys, the heart and the full medication list.

“My legs went numb” might have a sodium and fluid piece. It might just as easily trace back to blood pressure dropping on standing, a narrowed spinal canal, circulation, nerves worn down by years of high blood sugar, or a nutrient gap. Untangling it starts with a good description of what happens, when, and how long it lasts.

Neither answer lives in the salt shaker. Both live in the whole picture.

The takeaway I’d leave with you is small and practical. Ask why before you ask how much. Bring the full list of medications and the blood sugar readings. Notice the pattern, not just the moment. And treat every single number as one clue in a longer case.

Salt was never the whole suspect list. It was just the loudest name on it.
