Insulin resistance is becoming increasingly common, yet many people do not know they have it until routine blood work reveals a problem. The good news is that it can often be identified before diabetes develops, giving you an opportunity to take action.

What Is Insulin Resistance?
Insulin resistance occurs when the body’s cells no longer respond to insulin as effectively as they should. Insulin is a hormone made by the pancreas that helps move glucose from the bloodstream into the cells, where it is used for energy.
When the cells become resistant, the pancreas produces more insulin to keep blood sugar levels within a normal range. Over time, the pancreas may no longer be able to keep up with the body’s needs, causing blood sugar levels to rise.
Insulin resistance is not diabetes, but it is a major risk factor for developing type 2 diabetes if left untreated.
What Causes Insulin Resistance?
Insulin resistance usually develops because of several factors working together rather than a single cause. Common contributors include:
- Excess body fat: Carrying extra weight, particularly around the abdomen, can interfere with how the body responds to insulin.
- Hormonal conditions and menopause: Conditions such as polycystic ovary syndrome (PCOS) and hormonal changes during perimenopause and menopause may reduce insulin sensitivity and make blood sugar regulation more difficult.
- Physical inactivity: Regular exercise helps muscles use glucose more efficiently, while inactivity can reduce insulin sensitivity.
- Family history: Genetics may increase the likelihood of developing insulin resistance, especially if close relatives have type 2 diabetes.
- Poor sleep and chronic stress: Inadequate sleep and long-term stress can affect cortisol levels and interfere with healthy blood sugar regulation.
What Are the Symptoms of Insulin Resistance?
Many people have no obvious symptoms during the early stages. In some cases, insulin resistance is discovered only after blood tests reveal abnormal blood sugar levels or other signs of metabolic dysfunction.
When symptoms do occur, they may include:
- Fatigue, particularly after meals
- Increased hunger or frequent cravings for carbohydrates
- Difficulty losing weight
- Weight gain around the abdomen
- Dark, velvety patches of skin on the neck, armpits, or groin (acanthosis nigricans)
Because these symptoms can overlap with many other conditions, a medical evaluation is often needed to determine the underlying cause.
How Can Insulin Resistance Affect Your Health?
Insulin resistance affects more than blood sugar. Without treatment, it can contribute to several long-term health conditions.
Type 2 Diabetes
One of the most common complications is type 2 diabetes. As insulin resistance worsens, the pancreas may eventually be unable to produce enough insulin to keep blood sugar within a healthy range.
Metabolic Syndrome
Insulin resistance is a major contributor to metabolic syndrome, a group of conditions that often occur together, including:
- Elevated blood pressure
- High blood sugar
- Increased abdominal fat
- Abnormal cholesterol or triglyceride levels
These factors increase the risk of cardiovascular disease and other metabolic complications.
Weight Gain and Menopause
Hormonal changes during perimenopause and menopause can make insulin resistance more pronounced for some women. As estrogen levels decline, changes in body fat distribution and insulin sensitivity may make it easier to gain weight and more difficult to regulate blood sugar.
Fatty Liver Disease
Insulin resistance is also linked to fatty liver disease (MASLD). Excess fat can accumulate in the liver, leading to inflammation and, in some cases, progressive liver damage.
Can Insulin Resistance Be Improved?
For many people, insulin sensitivity can improve with consistent lifestyle changes, especially when addressed early.
Treatment may include:
- Regular physical activity, including both aerobic exercise and strength training
- Weight management through lifestyle changes and GLP-1 medications, when appropriate, to support blood sugar control and metabolic health.
- Eating more fiber, lean protein, and minimally processed carbohydrates
- Managing chronic stress
- Bioidentical hormone replacement therapy (BHRT) for some women whose insulin resistance may be influenced by hormonal changes during perimenopause or menopause
Addressing the Factors Behind Insulin Resistance
At Madison Integrative Medicine, Blake Gilliam, CRNP, takes a functional medicine approach to insulin resistance by looking beyond blood sugar to identify the factors contributing to metabolic dysfunction.
Evaluations may include insulin levels, hormone balance, inflammation, nutrition, sleep, stress, and other factors that influence metabolic health.
Treatment is personalized and may include nutrition and lifestyle recommendations, GLP-1 medications when appropriate, and bioidentical hormone replacement therapy for women whose hormonal changes may be contributing to insulin resistance and other metabolic concerns.

FAQs
What foods help improve insulin sensitivity?
A diet rich in vegetables, lean protein, whole grains, legumes, healthy fats, and high-fiber foods may help improve insulin sensitivity while reducing blood sugar spikes.
How long does it take to improve insulin sensitivity?
The timeline varies depending on the individual and the underlying cause. Some people see improvements within a few weeks of consistent lifestyle changes, while others may require ongoing medical treatment.
Can menopause and insulin resistance be treated together?
Yes. For some women, treatment may include lifestyle changes, GLP-1 medications, bioidentical hormone replacement therapy (BHRT), or a combination of approaches to improve metabolic health.
