Types of Diabetes Mellitus

Type 1 Diabetes (Juvenile Diabetes Mellitus)

Type 1 diabetes is an autoimmune condition where the body’s immune system mistakenly attacks the insulin-producing cells in the pancreas. As a result, the body can no longer produce insulin, a hormone needed to regulate blood sugar. Individuals with Type 1 diabetes require lifelong insulin therapy.

Type 2 Diabetes (Insulin-Resistance Diabetes Mellitus)

The most common form, Type 2 diabetes occurs when the body does not make enough insulin or when cells no longer respond properly to it—a condition known as insulin resistance. Lifestyle factors, genetics, and age often play a role in developing this type.

Common Symptoms

Recognizing early signs of diabetes can support timely medical consultation and management. Symptoms may include:

  • Increased thirst
  • Frequent urination
  • Fatigue
  • Blurred vision
  • Unexplained weight loss
  • Slow-healing wounds or sores

These indicators may seem subtle at first, but attention to these changes can significantly impact health outcomes.

Potential Complications

When unmanaged, diabetes can lead to serious health complications.

Acute Complications:

  • Hypoglycemia: A sudden drop in blood sugar that may cause blurred or double vision, clumsiness, disorientation, or seizures.

Severe Long-Term Complications:

  • Heart attack
  • Stroke
  • Neuropathy (nerve damage)
  • Amputations
  • Sexual dysfunction
  • Hearing loss

Awareness and consistent management are vital to preventing these conditions.

Diagnosis and Testing

Healthcare professionals diagnose diabetes through blood tests that measure glucose levels. Key diagnostic tests include:

  • Fasting Blood Glucose (FBG): Conducted after 8 hours of no food or drink (except water).
  • Random Blood Glucose Test: Can be taken at any time regardless of meals.
  • HbA1c (Glycated Hemoglobin Test): Reflects average blood sugar levels over the past two to three months.

Diagnostic Ranges

Test Normal Prediabetes Diabetes Melitus
FBS 70-100 mg/dl 100 – 125 mg/dL 126 mg/dL or higher
Random N/A N/A 200 mg/dL or higher
HbA1c <5.7% 5.7% – 6.4% 6.5% or higher

Management and Treatment

Managing diabetes is a daily commitment, but with proper care, individuals can lead healthy and fulfilling lives.

  • Blood Sugar Monitoring: Regular monitoring helps track progress and adjust treatment plans.
  • Medications: Oral medications such as metformin help those who still produce insulin regulate their blood sugar levels.
  • Insulin Therapy: Essential for people with Type 1 diabetes and sometimes needed for Type 2.
  • Healthy Diet: Balanced meals—especially managing carbohydrate intake—directly influence blood sugar levels.
  • Exercise: Physical activity improves insulin sensitivity and supports overall well-being.

Prevention Strategies

While Type 1 diabetes cannot be prevented, Type 2 diabetes often can be delayed or avoided through healthy habits:

  • Eat a balanced, nutritious diet
  • Engage in regular physical activity
  • Maintain a healthy weight
  • Manage stress effectively
  • Limit alcohol consumption
  • Ensure adequate sleep
  • Quit smoking
