Five Signs Your Insulin Is Running High

The blood test came back fine. Your doctor said your sugar was normal.

And yet. You are sleepy after lunch most days. You are hungry again an hour after eating. Your waist is thicker than it was, and it feels firm rather than soft. There are a couple of small skin tags on your neck that were not there before.

It is easy to think these are just getting older. Often they are something more specific, and something you can work with.

1. Why a normal blood sugar test can miss it

Insulin is the hormone that moves sugar out of your blood and into your cells. When you eat, your blood sugar rises, and insulin brings it back down.

Over time, if the body is flooded with sugar often, the cells start to respond less to insulin. The body’s answer is simple. It makes more insulin.

That extra insulin does its job. It keeps your blood sugar looking normal. So a blood sugar test comes back fine, while insulin is working much harder than it should, behind the scenes.

This can go on for years. By the time blood sugar finally starts to rise, insulin has often been high for a long time. That is why the signs below are worth knowing. They can show up long before the numbers do.

2. Sign one: you are sleepy after meals

A meal that sends you to the sofa is telling you something.

When a lot of sugar arrives at once, your blood sugar rises fast. If insulin is already running high, it can bring it down too fast. That drop is the heavy, foggy feeling an hour after eating.

A bit of drowsiness after a big meal is normal. Needing a nap after an ordinary lunch, most days, is worth noticing.

3. Sign two: hungry an hour after eating

You had a proper meal. An hour later, you are looking in the cupboard.

This is often the same fall. Blood sugar drops below where it started, and your brain reads that as hunger. It usually asks for something sweet or starchy, because that is the fastest fix.

The cravings are not weakness. They are the body chasing the dip it just made.

4. Sign three: a firm, hard belly

There are two kinds of belly fat. The soft kind sits under the skin, and you can pinch it. The firm kind sits deeper, around the organs, and pushes the belly out from inside.

High insulin tells the body to store fat, and it tends to favour that deep spot. So a waist that has thickened and feels firm, while your arms and legs have not changed much, is a common sign.

A soft tape measure at the belly button, once a month, tells you more than the scale does here.

5. Sign four: skin tags

Small, soft flaps of skin, usually on the neck, in the armpits or under the bra line.

Insulin does not only move sugar. At high levels it also acts as a growth signal on skin cells. Skin tags are one of the places that shows. A few can be nothing. A cluster that has appeared over the last year or two is worth mentioning to your doctor.

6. Sign five: darker, velvety skin in the folds

Some people notice skin that has turned darker and slightly velvety at the back of the neck, in the armpits, or on the elbows and knuckles. It can look like dirt that will not wash off.

It is the same growth signal at work, and it is one of the clearer outside signs that insulin has been high for a while. If you notice it, it is a good reason to ask your doctor about it directly.

7. What brings insulin down

The good news is that insulin responds quickly to how you eat and move. None of this needs a special diet.

Give it a break between meals. Insulin takes a few hours to come back down after you eat. If you snack between meals, it never gets the chance. Three proper meals, without grazing in between, gives it long gaps to fall.

Change the order on your plate. Protein and vegetables first, starch and anything sweet last. The food that goes down first slows the rest, so sugar arrives more gently and less insulin is needed.

Add fibre. Beans, lentils, oats and vegetables slow a meal down and keep you full longer.

Walk after your biggest meal. Working muscles can pull sugar in from the blood with very little insulin. Ten minutes is enough to make a difference.

Build muscle. More muscle means more room to store sugar, at every meal. Twice a week is a real start.

Protect your sleep. One short night makes the body handle sugar less well the next day.

8. A week that brings insulin down

It helps to see what this looks like in an ordinary week, because none of it is dramatic.

Breakfast becomes eggs and a slice of wholemeal toast instead of cereal and juice, so the morning starts with protein rather than a rush of sugar. The ten o’clock biscuit goes, because breakfast now lasts until lunch. Lunch starts with the salad or the vegetables, and the bread comes last. After lunch there is a ten-minute walk, even if it is just round the car park at work. The three o’clock snack becomes a cup of tea. Dinner is at the table, done by eight, with nothing after.

On two evenings, there are ten minutes of sit-to-stands and wall push-ups while the dinner cooks.

That is the whole week. You have eaten roughly the same amount of food. But insulin has had long gaps to fall, several times a day, and muscles have been working when the sugar arrived. Most people notice the after-lunch slump easing first, often within a fortnight.

9. Asking your doctor

A standard blood sugar test does not measure insulin itself. If several of these signs sound like you, it is fair to ask your doctor about it. Mention the signs, how long you have noticed them, and any change in your waist.

This is not something to diagnose from a web page. It is something to bring to the right person with good notes.

Why these signs are worth taking seriously

None of these signs is dangerous on its own. A skin tag is a skin tag. A sleepy afternoon is a sleepy afternoon.

What makes them worth noticing is that they tend to arrive together, and they tend to arrive years before a blood sugar test changes. That gives you time. Time to make a few small changes while they are easy, rather than waiting for a number on a report to make the decision for you.

And the same habits that bring insulin down also tend to help energy, sleep and cravings. So even if you never find out exactly what your insulin is doing, the changes are worth making.

Start with one

Pick the easiest change for you this week.

For most people, that is stopping the snacks between meals. Not less food overall, just the same food at mealtimes, with gaps in between. If you get hungry, add a little more protein to the meal before.

Keep it for a week. Notice whether the after-lunch slump is any smaller, and whether you are less hungry an hour after eating. Those two signs often move first.
