Diabetes Demystified: Causes, Types, Symptoms, Treatment & Essential Diet Tips

Diabetes is a growing global health concern that affects how your body regulates blood sugar (glucose). Whether you’re managing diabetes or trying to prevent it, understanding its causes, symptoms, treatment, and especially your diet, is key to living a healthier life.

What is Diabetes?

Diabetes is a chronic condition where your body cannot produce or properly use insulin, a hormone that regulates blood sugar. When glucose builds up in your blood instead of being used for energy, it can lead to serious health problems over time.

Types of Diabetes

1. Type 1 Diabetes

• Autoimmune disorder; the body attacks insulin-producing cells.
• Typically appears in childhood or adolescence.
• Requires lifelong insulin therapy.

2. Type 2 Diabetes

• Most common type; often linked to lifestyle factors.
• Body becomes resistant to insulin or produces it inefficiently.
• Can often be managed through diet, exercise, and oral medication.

3. Gestational Diabetes

• Occurs during pregnancy and usually resolves after childbirth.
• Increases risk of type 2 diabetes later in life.

4. Prediabetes

• Blood sugar levels are higher than normal, but not yet in the diabetic range.
• A critical stage where lifestyle changes can reverse the condition.
