Understanding Metformin and Its Role in Diabetes Management
Metformin is a commonly prescribed medication for the management of type 2 diabetes, primarily known for its ability to help lower blood glucose levels. It works mainly by reducing hepatic glucose production, improving insulin sensitivity, and enhancing glucose uptake by tissues. As effective as it is, some patients may experience side effects that could complicate their treatment. One such adverse effect is metformin-induced anemia, which can occur due to its impact on vitamin B12 absorption.
Understanding the Connection: Metformin can interfere with the absorption of vitamin B12 in the gut, leading to potential deficiencies over time. This is particularly problematic since vitamin B12 is essential for red blood cell production. Patients taking metformin should be aware of the symptoms of anemia, which include:
- Fatigue: Feeling unusually tired or weak.
- Pale Skin: A noticeable change in skin color can indicate reduced red blood cell levels.
