Metformin Side Effects

Hello 1-GSM Visitors, Metformin is a drug that is commonly prescribed to individuals with type 2 diabetes. It is used to lower blood sugar levels and improve insulin sensitivity. While this medication can be very effective, it is not without its side effects. In this article, we will explore the top three side effects of metformin.

Metformin Side Effects

1. Digestive Issues

One of the most common side effects of metformin is digestive issues. These can include nausea, vomiting, diarrhea, and abdominal pain. These symptoms are usually mild and go away on their own within a few days of starting the medication. However, if they persist or become severe, it is important to speak with your doctor.

2. Vitamin B12 Deficiency

Another side effect of metformin is a deficiency in vitamin B12. This vitamin is important for nerve function and the production of red blood cells. Long-term use of metformin can lead to a decrease in vitamin B12 levels, which can cause symptoms such as fatigue, weakness, and numbness or tingling in the hands and feet.

3. Lactic Acidosis

Lactic acidosis is a rare but serious side effect of metformin. It occurs when there is a buildup of lactic acid in the blood, which can be life-threatening. Symptoms of lactic acidosis include muscle pain, weakness, and difficulty breathing. If you experience any of these symptoms while taking metformin, you should seek medical attention immediately.

How to Minimize Side Effects

While metformin can cause side effects, there are things you can do to minimize them. For example, taking the medication with food can help reduce digestive issues. Additionally, taking a vitamin B12 supplement can help prevent a deficiency. It is important to talk to your doctor about any concerns you may have and to follow their instructions for taking the medication.


In conclusion, metformin is a medication that can be very effective for managing type 2 diabetes. However, it is not without its side effects. The most common side effects are digestive issues, while a deficiency in vitamin B12 and lactic acidosis are more serious but rare. If you are experiencing any side effects while taking metformin, it is important to speak with your doctor. By working together, you can find a treatment plan that works for you.
