Metformin is commonly used to manage diabetes, but its off-label use for weight loss has raised questions about potential side effects.
Q: What is Metformin?
Metformin is a medication primarily used to treat type 2 diabetes. It works by decreasing glucose production in the liver and improving insulin sensitivity.

Q: What are the common side effects of Metformin?
- Gastrointestinal issues: These include nausea, diarrhea, and abdominal pain.
- Vitamin B12 deficiency: Long-term use of Metformin can reduce the absorption of Vitamin B12.
- Lactic acidosis: A rare but severe condition that can occur due to the accumulation of lactic acid.
