Diabetes is a chronic condition that affects how the body processes glucose, a type of sugar that serves as the body's main source of energy. There are two main types of diabetes: type I and type II.

Type I diabetes, also known as insulin-dependent diabetes, is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. This results in a lack of insulin, the hormone responsible for regulating blood sugar levels. The exact cause of type I diabetes is not fully understood, but it is believed to be a combination of genetic and environmental factors.

Type II diabetes, also known as non-insulin-dependent diabetes, is the most common form of diabetes and is characterized by insulin resistance, where the body's cells do not respond properly to insulin. This leads to high levels of glucose in the blood. The exact cause of type II diabetes is also not fully understood, but it is believed to be a combination of genetic and lifestyle factors, such as obesity, lack of physical activity, and poor diet.

Both types of diabetes can lead to serious complications if not properly managed, including heart disease, stroke, kidney failure, and nerve damage. Treatment for diabetes typically involves a combination of medication, lifestyle changes, and monitoring blood sugar levels.

Diabetes is a chronic metabolic disorder characterized by elevated blood glucose levels (hyperglycemia). It results from either the pancreas not producing enough insulin, or the body's cells not responding properly to the insulin produced.

Types of Diabetes

Type I Diabetes (Insulin-Dependent Diabetes)

- Cause: Autoimmune disorder where the body's immune system mistakenly attacks and destroys the beta cells in the pancreas, which produce insulin.
- Genetics: Family history of type I diabetes increases the risk.
- Environmental factors: Viral infections, dietary triggers (e.g., gluten) have been suggested to play a role.
- Onset: Usually develops in childhood or adolescence.
- Symptoms: Thirst, frequent urination, weight loss, fatigue, blurry vision.
- Treatment: Requires insulin therapy (by injection or pump) lifelong.

Type II Diabetes (Non-Insulin-Dependent Diabetes)

- Causes:
- Insulin resistance: The body's cells become less sensitive to insulin, which leads to increased blood glucose levels.
- Beta cell dysfunction: The pancreas does not produce enough insulin to meet the body's needs.
- Risk factors:
- Obesity
- Sedentary lifestyle
- Family history of type II diabetes
- Age (over 45 years old)
- Certain ethnicities (e.g., African Americans, Hispanic Americans)
- Onset: Typically develops in adulthood.
- Symptoms: Similar to type I diabetes, but often less severe.
- Treatment: May include lifestyle changes (diet, exercise), oral medications (e.g., metformin), and in some cases, insulin therapy.
