What Is Type 1 Diabetes?

Type 1 diabetes is an autoimmune condition in which the immune system destroys insulin-producing beta cells in the pancreas. As a result, the body produces little or no insulin.

People with type 1 diabetes are insulin-dependent for life.

Causes of Type 1 Diabetes

Although the exact cause is unknown, factors include:

  • Genetic predisposition

  • Autoimmune reaction

  • Viral or environmental triggers

Type 1 diabetes is not caused by obesity, diet, or lifestyle.

Who Can Develop Type 1 Diabetes?

  • Children and adolescents

  • Young adults

  • Can occur at any age

Common Symptoms of Type 1 Diabetes

Symptoms often appear suddenly:

  • Excessive thirst

  • Frequent urination

  • Sudden weight loss

  • Extreme fatigue

  • Increased hunger

  • Blurred vision

Untreated cases may lead to diabetic ketoacidosis (DKA), a medical emergency.

Diagnosis of Type 1 Diabetes

Blood tests include:

  • Fasting blood glucose

  • Random blood sugar

  • HbA1c

  • Autoantibody testing

Treatment and Management

Management focuses on:

  • Insulin injections or insulin pump therapy

  • Regular blood sugar monitoring

  • Balanced nutrition

  • Physical activity

  • Ongoing medical supervision

Conclusion

Type 1 diabetes is a lifelong condition, but with proper insulin therapy and regular monitoring, individuals can lead healthy and productive lives.
