What Is Insulin Resistance? Symptoms, Causes and Treatment

The majority of individuals don't hear the term insulin resistance until they begin to see abnormal results on their sugar readings or are diagnosed by their medical professional with prediabetes. However, it's typically a lot sooner than this that a problem starts. It begins with the body producing insulin but the cells fail to respond to the insulin in the proper way and thus require more insulin to pump glucose out of the blood and into the cells.

That is why insulin resistance is not all the time dramatic at first. A few people report changes in their shape around the belly. Others may feel tired after eating, very hungry, forgetful, or not be able to lose weight. Many individuals may not have any obvious symptoms and are only diagnosed by blood tests.

What Insulin Resistance Actually Means

Insulin is a hormone that is secreted by the pancreas. It is supposed to provide assistance in moving the sugar from food into the cells so that the body can use it for energy. A healthy level of blood sugar means insulin is functioning well.

Insulin resistance involves a diminished response. The cells don't work as they should and the pancreas continues to secrete more insulin to try to get them to do the same thing. For a time, the body copes by making extra insulin. Later, the pancreas cannot sustain the blood sugar level and again it begins to rise. Over time that can lead to insulin resistance developing into prediabetes and type 2 diabetes.

It isn't just diabetes, either. Insulin resistance also has been associated with metabolic syndrome, fatty liver disease and disorders of blood lipids as well as a greater risk of cardiovascular disease.

Insulin Resistance Causes That Often Build Quietly

Many insulin resistance causes are tied to routine and metabolism. Physical inactivity is one of the common contributors. Excess body fat, especially around the liver, pancreas, and abdomen, also increases risk, although insulin resistance can still happen in people who are not visibly overweight.

Food pattern matters too. Constant excess calorie intake, weight gain, and long-term blood sugar overload can push the body toward reduced insulin sensitivity. Researchers also note that hyperinsulinemia and excess caloric intake may drive some of the metabolic dysfunction seen in insulin resistance.

Some causes are not purely lifestyle related. Family history, increasing age, steroid medicines, antipsychotic drugs, PCOS, sleep apnea, fatty liver disease, Cushing’s syndrome, and certain rare disorders can all play a role. Hormonal stages such as puberty, pregnancy, and menopause can also make insulin resistance more likely in some people.

That is why this condition should not be reduced to “you ate too much sugar.” Sometimes lifestyle is a major factor. Sometimes hormones, medicines, genetics, or other illnesses are sitting in the background as well.

Symptoms of Insulin Resistance You Should Notice Early

The symptoms of insulin resistance are not always obvious. In fact, some people have no symptoms and only get picked up during routine tests. When signs do appear, they are often indirect.

Common changes can include:

• Tiredness or difficulty concentrating.

• Increased hunger or unusual cravings.

• Weight gain, especially around the waist.

• Dark, velvety skin patches called acanthosis nigricans.

• Skin tags in some people.

• High blood pressure, high triglycerides, low HDL, or abnormal fasting glucose on reports.

One high cortisol symptom is not relevant here, but one insulin-related sign alone still does not confirm the condition. The real picture appears when body changes, waistline changes, family history, and lab markers start lining up together.

Insulin Resistance Treatment and What Actually Helps

The one-and-only solution for insulin resistance treatment doesn't exist. The goal is to restore insulin sensitivity to the body and to avoid the development of prediabetes and type 2 diabetes.

One of the most effective tools is physical activity. Facilitates insulin sensitivity in short and long term effects.

• Weight loss may also improve people's insulin resistance, particularly for individuals with overweight or obesity.

• Eating balanced meals centered around vegetables and fruits, whole grains, lean protein, and consistent eating habits can help to decrease the stress on blood sugar control.

• Another factor is sleep and stress, as there are other ways to improve overall metabolic health besides just diet choices.

In a few instances, medicines may be used. There is no medication that is specifically indicated for insulin resistance; however, certain medications (e.g. metformin and thiazolidinediones) might be used when treating insulin resistance in the proper clinical context.

If you are already having fatigue, fluctuation of weight, changes in your skin, abnormal sugar levels, PCOS, or family history of these, it is a good thing to be evaluated as early as possible. Insulin resistance can be measured along with blood sugar control, hormones, metabolism and long term risk of diabetes and treatment is provided back to the actual cause, not just with educated guesswork.
