Metformin Unveiled: 10 Essential Side Effects You Need to Know

7. Taste Disturbances: A Subtle Impact

Some metformin users report changes in taste, such as a metallic taste in the mouth. This side effect, although not harmful, can affect appetite and overall enjoyment of food. The exact cause of taste disturbances is not well understood, but it is thought to be related to the drug’s interaction with taste receptors or changes in saliva composition. For most, this side effect is temporary and resolves with continued use. Maintaining good oral hygiene and experimenting with different flavors and foods can help mitigate this minor inconvenience. While taste disturbances are not a major concern, they can impact quality of life and dietary habits.

8. Fatigue and Weakness: A Hidden Challenge

Fatigue and weakness are less commonly reported side effects of metformin but can significantly impact daily life for those affected. These symptoms may result from vitamin B12 deficiency, changes in blood sugar levels, or other metabolic effects of the drug. It is important for patients experiencing persistent fatigue to discuss this with their healthcare provider, as it may indicate the need for further investigation or adjustment of treatment. Addressing underlying causes, such as nutritional deficiencies or medication interactions, can help alleviate these symptoms. Ensuring adequate rest, hydration, and nutrition can also support overall energy levels while on metformin.
