What are metformin's side effects?

Metformin, which is used primarily for managing type 2 diabetes, can cause several side effects. Common side effects include gastrointestinal issues such as nausea and appetite suppression. Nausea is especially noted when first taking metformin or when dosages are increased rapidly 1 2. Additionally, while not typical, some might experience a general feeling of discomfort due to its dramatic impact on blood sugar levels 3.

It's worth noting that while metformin influences metabolic pathways and can have indirect effects on energy production, these actions result from its role in altering glucose metabolism rather than directly causing side effects like those from more toxic substances 4. As always, it's important to consult with a healthcare provider regarding potential side effects and to determine appropriate dosage.
