Understanding Diabetes

Diabetes is a chronic medical condition that affects millions of people worldwide. Characterized by elevated blood sugar levels, diabetes occurs when the body either doesn’t produce enough insulin or cannot effectively use the insulin it produces. Insulin is a hormone crucial for regulating blood sugar (glucose) and enabling cells to use it for energy. Symptoms:
  • Increased Thirst and Hunger: As cells are deprived of glucose, the body craves more nutrients.
  • Frequent Urination: Excess glucose in the bloodstream leads to increased urination.
  • Fatigue: Lack of energy due to cells not receiving enough glucose.
  • Unexplained Weight Loss: The body may break down muscle and fat for energy.
Types of Diabetes:
  1. Type 1 Diabetes:
    • Cause: Autoimmune response where the immune system attacks and destroys insulin-producing beta cells in the pancreas.
    • Onset: Typically diagnosed in childhood or adolescence.
    • Treatment: Insulin therapy is essential for managing blood sugar levels.
  2. Type 2 Diabetes:
    • Cause: Insulin resistance, where the body’s cells don’t respond properly to insulin, and over time, the pancreas can’t produce enough insulin to maintain normal glucose levels.
    • Onset: More common in adults but can develop at any age.
    • Treatment: Lifestyle changes, oral medications, and sometimes insulin therapy.
  3. Gestational Diabetes:
    • Cause: Develops during pregnancy when the body cannot produce enough insulin to meet increased needs.
    • Onset: Typically diagnosed during the second or third trimester.
    • Risk: Increases the likelihood of developing type 2 diabetes later in life.
Causes and Risk Factors:
  • Genetics: Family history plays a role in both type 1 and type 2 diabetes.
  • Lifestyle Factors: Poor diet, lack of physical activity, and obesity increase the risk of type 2 diabetes.
  • Age: The risk of type 2 diabetes increases with age.
  • Ethnicity: Some ethnic groups are at a higher risk.
