Here’s a detailed overview of 10 common metformin side effects that your doctor wants you to discuss, along with guidance on when to seek medical attention. Metformin is widely used for type 2 diabetes, but knowing the potential effects helps you use it safely.
10 Common Metformin Side Effects
1. Gastrointestinal Issues
- Nausea, vomiting, diarrhea, or abdominal discomfort are the most frequent side effects.
- Often mild and improve over time or if taken with meals.

- Monitor weight and ensure proper nutrition.
3. Metallic Taste in Mouth
- Temporary taste change may happen, usually mild and harmless.
4. Bloating and Gas
- Can accompany diarrhea or indigestion.
- Taking metformin with food often reduces this.
5. Vitamin B12 Deficiency

8. Skin Reactions
- Rarely, some people may develop rash or itching.
9. Hair Loss
