What is a common side effect of antibiotics?

Diarrhea is a well-known side effect of antibiotics and is often a result of the medication disrupting the natural balance of bacteria in the intestines. Antibiotics target bacteria causing infections, but they can also affect beneficial gut flora, leading to gastrointestinal disturbances. As the gut microbiome is altered, patients may experience loose stools or diarrhea.

While nausea, rash, and fatigue can also occur with antibiotic use, diarrhea is particularly common and frequently reported. It is important for patients to be aware of this possible side effect, as it can guide them in managing their symptoms and understanding their treatment better. In cases of severe or persistent diarrhea, patients are advised to consult their healthcare provider, as it may indicate an overgrowth of harmful bacteria or other complications.
