Giardiasis (Giardia lamblia)

It often starts quietly—maybe a family trip, a hike, or simply a glass of water that didn’t look suspicious at all. A few days later, the stomach cramps, bloating, and fatigue begin. Many patients come to SSRC thinking it’s “just acidity” or a routine stomach bug, only to learn they’re dealing with Giardiasis—an intestinal infection caused by the parasite Giardia lamblia.

With advanced diagnostics, tailored treatment plans, and a patient-centred approach, we help you recover fully and reclaim daily comfort.
