Insulin resistance is a condition where cells in your body become less responsive to insulin, the hormone that regulates glucose (sugar) levels in your blood.
As a result, your pancreas has to produce more insulin to get the same effect, which can lead to high blood sugar levels and eventually type 2 diabetes. In this article, we will explore the warning signs of insulin resistance so you can catch it early and take action to prevent or manage it.
Signs and Symptoms of Insulin Resistance
Insulin resistance often develops slowly over time, so you may not notice any symptoms until it has progressed to prediabetes or type 2 diabetes. However, there are some warning signs that you should be aware of:.
1. Increased Hunger and Cravings
Insulin helps transport glucose from your bloodstream into your cells for energy. When your cells become resistant to insulin, glucose can’t enter your cells, and your body responds by producing more insulin.
This can cause hunger and cravings for sugary or high-carb foods.
2. Fatigue and Brain Fog
High blood sugar levels can cause fatigue and brain fog, also known as “diabetes brain.” Insulin resistance can also lead to impaired glucose metabolism in the brain, which can affect memory and cognitive function.
3. Weight Gain
Insulin resistance can cause weight gain, especially around the abdomen. This is because high insulin levels can stimulate the production of fat cells and prevent the breakdown of existing fat cells.
4. High Blood Pressure
Insulin resistance can cause high blood pressure by damaging the lining of blood vessels and reducing blood flow. This can increase the risk of heart disease and stroke.

5. High Cholesterol and Triglycerides
Insulin resistance can increase the production of cholesterol and triglycerides, which are fats in your blood. This can raise your risk of heart disease and stroke.
6. Dark Patches on the Skin
Insulin resistance can cause dark, velvety patches on the skin, usually around the neck, armpits, or groin. This is called acanthosis nigricans and is a sign of insulin resistance and high insulin levels.
7. Polycystic Ovary Syndrome (PCOS)
Insulin resistance is a common cause of polycystic ovary syndrome (PCOS) in women. PCOS is a hormonal disorder that can cause irregular periods, fertility problems, and other health issues.
8. Sleep Problems
Insulin resistance can affect sleep by disrupting circadian rhythms and causing nighttime hypoglycemia (low blood sugar). This can lead to difficulty falling asleep, poor sleep quality, and daytime fatigue.
9. Increased Urination and Thirst
High blood sugar levels can cause increased urine production and thirst. This is because your kidneys try to flush out excess sugar from your blood, and water is lost along with it.
10. Slow Wound Healing
Insulin resistance can slow down wound healing by decreasing blood flow and impairing immune function. This can increase the risk of infections and other complications.
Conclusion
If you notice any of these warning signs, it’s important to talk to your doctor and get your blood sugar levels checked.
Early detection and management of insulin resistance can help prevent or delay the onset of type 2 diabetes, heart disease, and other complications. Lifestyle changes such as a healthy diet, regular exercise, and stress reduction can also help improve insulin sensitivity and prevent insulin resistance.
