Insulin is a key that lets sugar into your cells. In insulin resistance the lock gets stiff, so the body makes more keys, and high insulin tells the ovaries to make more androgens. Lean women can have it too, and early action helps.
Insulin is easy to picture as a key. It lets sugar from your blood into your cells, where it becomes energy. When everything works well, the key turns, the door opens and sugar goes in.
In insulin resistance the lock gets stiff. The key does not turn as easily. The body copes in the only way it can, by making more keys. Blood sugar may look fine for years because insulin is working overtime in the background.
Why this matters for the ovaries
High insulin is not a quiet change. It tells the ovaries to make more androgens, the hormones that cause acne, extra dark hair and thinning at the parting. Extra androgens disturb ovulation. That is the loop behind a lot of PCOD, and weight gain around the belly can make the stiffness worse. Then the loop turns again.
Lean women can have it too
A common myth says only overweight women get insulin resistance. Not true. Lean women can have PCOD and insulin resistance too. If you are slim and keep being told your weight is fine, ask whether your sugar and insulin have ever been tested.
Signs you may notice
None of these proves anything on its own. Together they are a reason to ask.
- Dark, velvety patches on the neck or underarms
- Skin tags
- Sugar cravings
- Belly fat
- Feeling sleepy after meals
Some women have no signs at all. In that case, only a blood test and a tape measure give the answer.
Tests doctors may advise
Your doctor chooses the tests. They may include:
- fasting sugar and fasting insulin
- HbA1c, which reflects your average sugar over the last few months
- an OGTT, where blood sugar is checked before and after a sugary drink
- HOMA-IR, a number worked out from your fasting sugar and insulin
Doctors may also look at your waist, blood pressure and cholesterol, because insulin resistance travels with them. When three or more of five markers are present, that is called metabolic syndrome, and a separate article explains it.
What helps
The good news is that you can change this loop in ordinary ways. Small habits you can keep beat big plans you drop.
Food
There is no single PCOD diet. The goal is steady sugar and less inflammation. A plate that works at lunch and dinner is half vegetables and salad, a quarter protein such as dal, paneer, egg or curd, and a quarter whole grain such as millet roti. Eating vegetables first, then protein, with carbohydrates last, helps keep sugar steadier after a meal. Protein with every meal, especially breakfast, also helps. Maida, sugary drinks and packaged snacks push insulin up. Avoid crash diets. They backfire.
Movement
Movement makes your cells listen to insulin again. A sensible target is 150 minutes a week of brisk walking, cycling, swimming or dance, plus 2 days of strength work. Even 10 minutes counts. A 10-minute walk after meals is an easy habit to start with.
Sleep and calm
Sleep for 7 to 9 hours at the same time each night, and keep screens off for an hour before bed. Poor sleep and stress hormones both nudge insulin the wrong way.
Weight, if it applies
If you carry extra weight, losing 5 to 10% of your body weight can bring back regular ovulation and periods. That figure is a gentle target, not a deadline.
Medicines
Some women are advised metformin or other medicines. They are chosen for your goal and prescribed by your doctor. Do not start any medicine or supplement, including inositol or vitamin D, on your own.
A few small starting points
Pick one habit this week, not five. Walk for 10 minutes after lunch or dinner. Add one protein food to breakfast, such as an egg, curd, paneer or sprouts. Swap one sugary drink for water, since 2 to 3 litres of water a day is a good aim. These are small, and they are the kind of steps that last. Write down how you feel after meals for a week, and bring the note to your doctor.
The point to remember
Insulin resistance is common in PCOD, it does not depend on your weight, and it responds to ordinary, repeatable changes. Early care also lowers the chance of problems later, such as type 2 diabetes. You can break the loop at any point.
