Insulin Resistance

From WikiMD's Wellnesspedia

Insulin Resistance is a pathological condition in which cells fail to respond normally to the hormone Insulin. When the body produces insulin under conditions of insulin resistance, the cells are resistant to the insulin and are unable to use it as effectively, leading to high blood sugar. Beta cells in the pancreas subsequently increase their production of insulin, further contributing to a high blood insulin level. This often remains undetected and can contribute to the development of Type 2 Diabetes or Latent Autoimmune Diabetes of Adults.

Causes[edit | edit source]

There are many causes of insulin resistance, including genetics, stress, obesity, metabolic syndrome, pregnancy, infection or severe illness, steroid use, smoking, and sedentary lifestyle. Certain ethnicities are more susceptible to insulin resistance, including people of Asian, African, and Hispanic descent.

Symptoms[edit | edit source]

Symptoms of insulin resistance can include fatigue, hunger, brain fog, high blood pressure, high cholesterol levels, and weight gain. If left untreated, insulin resistance can lead to Type 2 Diabetes and prediabetes.

Diagnosis[edit | edit source]

Insulin resistance is often diagnosed through a fasting blood glucose test, oral glucose tolerance test, or with an HbA1c test. These tests show how well your body uses insulin.

Treatment[edit | edit source]

Treatment for insulin resistance includes lifestyle changes, medication, and weight loss. Medications such as metformin and thiazolidinediones can help. Regular exercise and a healthy diet can also improve insulin resistance.
