Type 2 Diabetes: Causes, Symptoms and Treatment

Type 2 diabetes is one of the most common chronic health conditions affecting millions of people worldwide. It occurs when the body becomes resistant to insulin or when the pancreas does not produce enough insulin to maintain normal blood sugar levels. Without proper treatment and lifestyle management, type 2 diabetes can lead to serious health complications affecting the heart, kidneys, nerves, and eyes.

At Tambaram Medical Center, patients can consult the best diabetologist in Chennai for comprehensive diabetes diagnosis, treatment, and long‑term management.

What is Type 2 Diabetes?

Type 2 diabetes is a metabolic disorder in which the body cannot effectively use insulin. Insulin is a hormone produced by the pancreas that allows glucose to enter the body’s cells to be used as energy.

When insulin does not work properly, glucose builds up in the bloodstream. This leads to high blood sugar levels, which over time can damage various organs and tissues.

Causes of Type 2 Diabetes

Type 2 diabetes develops due to a combination of genetic, lifestyle, and environmental factors.

• Insulin resistance
• Family history of diabetes
• Obesity or excess body weight
• Sedentary lifestyle
• Poor dietary habits
• Hormonal imbalances

Common Symptoms of Type 2 Diabetes

1. Frequent Urination

High blood sugar levels force the kidneys to work harder to filter excess glucose from the blood, resulting in frequent urination.

2. Excessive Thirst

Loss of fluids due to frequent urination causes increased thirst in many individuals with diabetes.

3. Increased Hunger

Despite eating regularly, the body may not be able to use glucose effectively, leading to persistent hunger.

4. Fatigue

When glucose cannot enter cells efficiently, the body lacks energy, causing fatigue and weakness.

5. Blurred Vision

High blood sugar levels may cause swelling in the eye lenses, leading to temporary vision problems.

6. Slow Healing Wounds

Diabetes can impair circulation and immune function, causing wounds to heal slowly.

7. Tingling or Numbness

Nerve damage caused by prolonged high blood sugar levels can lead to tingling or numbness in the hands and feet.
