The 10 Metformin Side Effects Your Doctor Hopes You Discuss — What Many Experience but Few Report
Metformin is one of the most commonly prescribed medications for type 2 diabetes, helping to control blood sugar levels effectively. While generally safe, it can cause side effects that are often underreported. Knowing these side effects can help you manage them better and discuss them with your doctor.
Here are 10 Metformin side effects you should be aware of:
1. Gastrointestinal Issues
- Nausea, vomiting, diarrhea, or stomach cramps are the most common side effects.
- Usually temporary, but persistent symptoms should be discussed with your doctor.
2. Loss of Appetite
- Some people notice a reduced desire to eat, which can contribute to weight loss.
3. Bloating and Gas
- Metformin can cause excessive gas or abdominal bloating, especially when starting the medication.
4. Metallic Taste in Mouth
- A strange metallic or bitter taste is a subtle but frequent complaint.
- It usually resolves over time.
5. Vitamin B12 Deficiency
- Long-term Metformin use may reduce B12 absorption, potentially leading to fatigue, nerve pain, or anemia.
- Regular monitoring is recommended.
6. Hypoglycemia (Low Blood Sugar)
- Metformin rarely causes hypoglycemia by itself but can when combined with other diabetes medications.
- Signs include dizziness, sweating, confusion, and rapid heartbeat.
7. Lactic Acidosis (Rare but Serious)
