What is Metformin?
Metformin is a common medication prescribed to manage type 2 diabetes. It helps control blood sugar levels, making it easier for the body to use insulin effectively. However, like any medication, it comes with potential side effects.
Common Side Effects of Metformin
Many people experience mild side effects when they start taking metformin. These usually go away as the body adjusts to the medication.
- Gastrointestinal Issues: Nausea, vomiting, and diarrhea are common. Eating metformin with food can help reduce these symptoms.

- Loss of Appetite: A decreased appetite can occur, leading to weight loss in some cases.

While less frequent, some side effects can be more serious and require medical attention.
- Lactic Acidosis: This rare but serious condition involves a buildup of lactic acid in the blood. Symptoms include muscle pain, difficulty breathing, and extreme tiredness.
- Vitamin B12 Deficiency: Long-term use of metformin can reduce vitamin B12 absorption, leading to deficiency. Symptoms include fatigue, weakness, and nerve damage.

Long-term use of metformin can have additional impacts on the body, which should be monitored by a healthcare provider.
