Question

Identify autoimmune diseases among the following.

• A. Pernicious Anemia
• B. Type II diabetes
• C. Type I diabetes
• D. Gestational diabetes

Answer 1

The Correct Option is A

An autoimmune disease occurs when the body's immune system mistakenly attacks its own tissues and cells. 

Step 1: Understanding the Given Diseases - Pernicious Anemia: An autoimmune disorder where the body destroys cells in the stomach lining that produce intrinsic factor, which is essential for vitamin B12 absorption. 
- Type II Diabetes: A metabolic disorder, not an autoimmune disease, caused by insulin resistance rather than immune system dysfunction. 
- Type I Diabetes: An autoimmune disease where the immune system attacks insulin-producing beta cells in the pancreas, leading to insulin deficiency. 
- Gestational Diabetes: A temporary condition that occurs during pregnancy due to hormonal changes, not an autoimmune disease. 

Step 2: Evaluating the Options - Option (A) - Correct: Pernicious Anemia is an autoimmune disease. 
- Option (B) - Incorrect: Type II Diabetes is a metabolic disorder, not autoimmune. 
- Option (C) - Correct: Type I Diabetes is an autoimmune disease. 
- Option (D) - Incorrect: Gestational Diabetes is a pregnancy-related condition. 

Step 3: Conclusion Since Pernicious Anemia and Type I Diabetes are autoimmune diseases, the correct answer is (A) and (C).
