What Is Insulin Resistance?

Insulin resistance is a condition where the cells in your body become less sensitive to insulin. Insulin is a hormone that helps glucose (sugar) from your blood enter the cells to be used for energy. When cells become resistant to insulin, they can't effectively absorb glucose, leading to higher blood sugar levels.

Causes of Insulin Resistance

There are several causes of insulin resistance, including:

• Excess weight and obesity: Fat, especially around the abdomen, increases the risk.
• Sedentary lifestyle: Lack of physical activity can contribute to insulin resistance.
• Genetics: If you have relatives with type 2 diabetes, your risk is higher.
• Poor diet: Consuming a high amount of carbohydrates and saturated fats can lead to insulin resistance.

Symptoms of Insulin Resistance

Insulin resistance often develops gradually and may not cause obvious symptoms in the early stages. However, over time, symptoms may include:

• Weight gain, especially around the abdomen
• Fatigue
• Constant hunger
• Darkening of the skin in folds and creases, such as the neck and armpits

Diagnosing Insulin Resistance

Diagnosing insulin resistance may involve several tests, such as:

• Fasting glucose test: Elevated blood sugar levels may indicate insulin problems.
• Glucose tolerance test: This test checks how your body handles sugar.
• Hemoglobin A1c: Measures your average blood sugar levels over the past 2-3 months.
• Insulin test: Measures the level of insulin in your blood.

Treatment and Management

Treating insulin resistance involves lifestyle changes and, in some cases, medication. Key steps include:

1. Diet

Reduce your intake of sugar and simple carbohydrates. Incorporate more vegetables, fruits, whole grains, and lean proteins. Healthy fats, such as those from nuts, seeds, olive oil, and fish, are also important.

2. Physical Activity

Regular exercise helps improve insulin sensitivity. Aim for at least 30 minutes of physical activity per day.

3. Weight Management

Losing weight, especially around the abdomen, can significantly improve your condition.

4. Medications

In some cases, your doctor may prescribe medications like metformin to help improve insulin sensitivity.

Preventing Insulin Resistance

Insulin resistance can be managed and even prevented with the right lifestyle choices. Regular medical checkups, healthy eating, and an active lifestyle are key to maintaining health and preventing the development of type 2 diabetes.
