Giardiasis is an intestinal infection caused by the parasite Giardia lamblia. It typically spreads through contaminated food or water, or by close contact with an infected person or animal. Symptoms of giardiasis often include diarrhea, abdominal cramps, bloating, nausea, and fatigue. In some cases, symptoms may be serious and last for several weeks. Treatment usually involves medication to kill the parasite and relieve symptoms. Good hygiene, such as washing hands thoroughly and avoiding untreated water sources, can help prevent giardiasis.
