Diabetes Mellitus Overview and Types

Overview

• Diabetes Mellitus is a chronic metabolic disorder characterized by high blood glucose levels.
• It occurs due to insufficient insulin production, insulin resistance, or both.

Types of Diabetes

1. Type 1 Diabetes

   • Autoimmune destruction of insulin-producing beta cells in the pancreas.
   • Typically diagnosed in children and young adults.
   • Requires lifelong insulin therapy.

2. Type 2 Diabetes

   • Characterized by insulin resistance and relative insulin deficiency.
   • More common in adults, often associated with obesity and sedentary lifestyle.
   • Managed through lifestyle changes, oral medications, and sometimes insulin.

3. Gestational Diabetes

   • Develops during pregnancy and usually resolves postpartum.
   • Increases risk for type 2 diabetes later in life.

Symptoms

• Increased thirst (polydipsia)
• Frequent urination (polyuria)
• Extreme hunger (polyphagia)
• Fatigue
• Blurred vision
• Slow-healing sores or frequent infections

Risk Factors

• Family history of diabetes
• Obesity and sedentary lifestyle
• Unhealthy diet, high in refined sugars and fats
• Age (especially over 45 years)
• Ethnicity (higher risk in certain populations)

Complications

• Cardiovascular disease
• Neuropathy (nerve damage)
• Nephropathy (kidney damage)
• Retinopathy (eye damage)
• Foot problems (ulcers and infections)
• Skin conditions

Diagnosis

• Fasting blood glucose test
• Oral glucose tolerance test (OGTT)
• Hemoglobin A1c test

Management

• Lifestyle Changes

  • Healthy diet: focus on whole foods, fruits, vegetables, and whole grains.
  • Regular physical activity: aim for at least 150 minutes per week.
  • Weight management: maintain a healthy body weight.

• Medications

  • Type 1: Insulin therapy.
  • Type 2: Metformin, sulfonylureas, DPP-4 inhibitors, GLP-1 receptor agonists, and insulin if needed.

Monitoring

• Regular blood glucose monitoring.
• Periodic A1c testing to assess long-term glucose control.
• Routine checks for complications (e.g., foot exams, eye exams, kidney function tests).

Prevention

• Maintain a healthy weight.
• Engage in regular physical activity.
• Eat a balanced diet low in sugar and saturated fats.
• Monitor blood sugar levels, especially in high-risk individuals.

Overview

• Diabetes Mellitus is a chronic condition marked by high blood glucose levels due to insufficient insulin production, insulin resistance, or both.

Types of Diabetes

• Type 1 Diabetes

  • Results from autoimmune destruction of pancreatic beta cells.
  • Usually diagnosed in children and young adults.
  • Requires lifelong insulin therapy for management.

• Type 2 Diabetes

  • Involves insulin resistance with relative deficiency of insulin.
  • More prevalent in adults; often linked to obesity and sedentary lifestyles.
  • Management includes lifestyle modifications, oral medications, and potentially insulin therapy.

• Gestational Diabetes

  • Develops during pregnancy and typically resolves after childbirth.
  • Increases the likelihood of developing type 2 diabetes later in life.

Symptoms

• Increased thirst (polydipsia)
• Frequent urination (polyuria)
• Extreme hunger (polyphagia)
• Fatigue
• Blurred vision
• Slow-healing sores and frequent infections

Risk Factors

• Family history of diabetes increases susceptibility.
• Obesity and sedentary lifestyle are significant contributors.
• Unhealthy diets high in refined sugars and fats elevate risk.
• Age over 45 years is a notable risk factor.
• Certain ethnic populations have a higher incidence.

Complications

• Potentially leads to cardiovascular disease.
• Can cause neuropathy, resulting in nerve damage.
• May result in nephropathy, damaging the kidneys.
• Retinopathy can occur, impacting vision.
• Patients may experience foot problems, including ulcers and infections.
• Skin conditions may arise as complications.

Diagnosis

• Blood glucose levels assessed through fasting blood glucose tests.
• Oral glucose tolerance test (OGTT) is used for further evaluation.
• Hemoglobin A1c test provides insights into long-term glucose control.

Management

• Lifestyle Changes

  • Emphasize a healthy diet focused on whole foods, fruits, and vegetables.
  • Engage in at least 150 minutes of physical activity per week.
  • Focus on weight management to maintain a healthy body weight.

• Medications

  • Type 1 diabetes management primarily through insulin therapy.
  • Type 2 diabetes may require medications such as Metformin, sulfonylureas, DPP-4 inhibitors, GLP-1 receptor agonists, and possibly insulin.

Monitoring

• Regular blood glucose monitoring is essential for effective control.
• Periodic A1c testing evaluates long-term glycemic control.
• Routine examinations are necessary to check for complications, including foot, eye, and kidney assessments.

Prevention

• Maintain a healthy weight through balanced diet and regular activity.
• Regular physical engagement is crucial for diabetes prevention.
• Consume a balanced diet low in sugar and saturated fats.
• Monitor blood sugar levels, especially for individuals at high risk.
