Giardiasis emerges as a result of Giardia lamblia, a microscopic, single-celled parasite that establishes itself in the intestines of both humans and animals.
Initial indicators of infection may encompass sensations of nausea, a decline in appetite, and discomfort in the upper intestine, coupled with an overall feeling of malaise, potentially accompanied by a mild fever and chills.
Following this, there is typically a sudden onset of explosive, watery diarrhea with an unpleasant odor, accompanied by increased flatulence and abdominal swelling. Additional acute symptoms include bloating, belching, cramping, and a reduced desire to eat; these manifestations typically appear 1 to 2 weeks after the ingestion of cysts. Individuals under stress or with weakened immune systems may experience more severe symptoms and a diminished ability to fend off the disorder.
The illness usually resolves on its own, lasting for a span of 2 to 6 weeks, but it may sporadically reoccur or progress into a chronic state. Nevertheless, not everyone who acquires the infection exhibits symptoms. Giardiasis is more prevalent in children, elderly individuals with compromised health, and those with dysgammaglobulinemias.
