What is a common symptom of giardiasis?

In giardiasis, a common symptom experienced by affected individuals is diarrhea. This gastrointestinal infection, caused by the protozoan parasite Giardia lamblia, frequently results in the production of loose, watery stools. In addition to diarrhea, patients may also experience abdominal cramps, bloating, and nausea. Although other symptoms might occasionally be present, such as fever or headaches, diarrhea is particularly characteristic of giardiasis and is often the most prominent symptom that leads to its diagnosis. Understanding this link between giardiasis and diarrhea is crucial in recognizing and treating the infection effectively.
