1. Gastrointestinal Disturbances: The Most Common Side Effect

One of the most frequently reported side effects of metformin is gastrointestinal disturbance, affecting up to 30% of users. Symptoms include nausea, vomiting, diarrhea, and abdominal discomfort. These symptoms often occur when starting the medication or after dose increases. While the exact mechanism is not fully understood, it is believed that metformin affects the gut microbiota composition, leading to these adverse effects. For many, these symptoms are temporary and can be mitigated by starting with a low dose and gradually increasing it. Taking metformin with meals or using the extended-release formulation may also help reduce gastrointestinal issues. Despite their prevalence, these side effects are generally not severe and tend to subside over time, allowing patients to continue benefiting from metformin’s glucose-lowering effects.
