Giardia parasites cause diarrhea from contaminated water
Microscopic Giardia parasites in tainted water sources can invade your gut, sparking painful diarrhea and highlighting the hidden dangers of everyday hydration.
Tiny Giardia parasites, often found in contaminated water, cause giardiasis, an intestinal infection marked by severe diarrhea. These resilient cysts survive chlorination and thrive in cool, damp places like streams and lakes, making them a threat in recreational areas and regions with poor sanitation. Once ingested, they attach to your small intestine, disrupting nutrient absorption and causing symptoms like watery diarrhea, cramps, and fatigue for weeks. Annually, giardiasis affects an estimated 1.2 million people in the US, especially hikers and young children, underscoring the critical need for clean water access.
