Types of Diabetes: Causes & Risk Factors

What Is Diabetes Mellitus?
Diabetes mellitus is a chronic condition that occurs when the body does not produce enough insulin or cannot use it effectively. As a result, blood glucose (blood sugar) levels rise and, if left untreated, may lead to complications affecting the heart, kidneys, eyes, and nerves.

Early diagnosis and proper medical care are essential to help prevent complications and improve long-term health.

Symptoms of Diabetes
Symptoms may develop gradually and vary depending on the type of diabetes. The most common include:

• Excessive thirst and hunger.
• Frequent urination.
• Persistent fatigue.
• Blurred vision.
• Slow-healing wounds.
• Tingling or numbness in the hands and feet.
• Unexplained weight loss.
• Sexual dysfunction in some patients.

If you experience one or more of these symptoms, it is important to schedule an evaluation with an Endocrinology specialist.

Types of Diabetes

Type 1 Diabetes
Type 1 diabetes is an autoimmune condition in which the body produces little or no insulin. It usually develops during childhood or adolescence and requires lifelong insulin therapy.

Type 2 Diabetes
Type 2 diabetes is the most common form of diabetes. It develops when the body becomes resistant to insulin or does not produce enough to maintain normal blood sugar levels.

It is often associated with excess weight, physical inactivity, and a family history of diabetes, although it can also occur in people with a healthy weight.

In many cases, it can be successfully managed with healthy lifestyle changes, regular exercise, proper nutrition, and medication.

Gestational Diabetes
Gestational diabetes develops during pregnancy, usually in the second or third trimester. Although it often resolves after delivery, it increases the mother's and baby's risk of developing Type 2 diabetes later in life.

Proper prenatal care and blood sugar monitoring help reduce potential complications.

Who Is at Higher Risk for Type 2 Diabetes?
Your risk increases if you have one or more of the following factors:

• Overweight or obesity.
• Family history of diabetes.
• High blood pressure.
• Physical inactivity.
• Previous gestational diabetes.
• Prediabetes or elevated blood glucose levels.

When Should You See a Specialist?
Don't wait for complications to develop. If you have symptoms or risk factors for diabetes, an evaluation with an endocrinologist and routine laboratory tests can help detect the condition early and allow treatment to begin before complications occur.
