What is Diabetes?

Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia – high blood sugar – resulting from defects in insulin secretion, insulin action, or both. Insulin,a hormone produced by the pancreas,allows glucose from food to enter cells to be used for energy.When this process fails, glucose builds up in the bloodstream.

There are three main types of diabetes:

• Type 1 Diabetes: An autoimmune condition where the body attacks and destroys insulin-producing cells in the pancreas. Typically diagnosed in childhood or adolescence.
• Type 2 Diabetes: The most common form,characterized by insulin resistance – where cells don’t respond effectively to insulin – and frequently enough a gradual decline in insulin production. Strongly linked to lifestyle factors.
• Gestational Diabetes: Develops during pregnancy and usually resolves after childbirth, but increases the risk of developing Type 2 diabetes later in life.

Risk Factors

Several factors can increase the risk of developing Type 2 diabetes. These include:

• Family History: Having a parent or sibling with diabetes.
• Obesity: Excess weight, particularly around the abdomen.
• Physical Inactivity: A sedentary lifestyle.
• Age: Risk increases with age, particularly after 45.
• Race/Ethnicity: Certain ethnic groups (African Americans, Hispanic americans, Native Americans, Asian Americans, and Pacific Islanders) are at higher risk.
• Prediabetes: Having blood sugar levels higher then normal, but not high enough to be diagnosed as diabetes.
• Gestational Diabetes: A history of gestational diabetes.

While Type 1 diabetes has a less clear set of risk factors,genetic predisposition and environmental triggers are believed to play a role.

Symptoms of Diabetes

Symptoms can vary depending on the type of diabetes and blood sugar levels. Common symptoms include:

• Frequent urination
• Excessive thirst
• Unexplained weight loss
• Increased hunger
• Blurred vision
• Slow-healing sores
• Frequent infections
• Fatigue
• Numbness or tingling in the hands or feet

many people with Type 2 diabetes have no noticeable symptoms in the early stages.

Diagnosis and Monitoring

Diabetes is typically diagnosed thru blood tests:

• Fasting Plasma Glucose (FPG): Measures blood sugar after an overnight fast.
• A1C Test: Provides an average blood sugar level over the past 2-3 months.
• oral glucose Tolerance Test (OGTT): Measures blood sugar levels after drinking a sugary drink.
• Random Plasma Glucose Test: Measures blood sugar at any time of day.

Regular monitoring of blood sugar levels is essential for managing diabetes. This can be done using a blood glucose meter or a continuous glucose monitor (CGM).
