Giardia
Synopsis
Giardia is a parasitic infection caused by Giardia lamblia (also known as Giardia intestinalis or Giardia duodenalis), a microscopic protozoan that infects the small intestine. It is a leading cause of parasitic gastrointestinal illness worldwide, especially in areas with poor water sanitation or after drinking contaminated water while camping or traveling.
Giardia is transmitted via the fecal-oral route, most commonly through:
-
Contaminated water (streams, lakes, or municipal supplies)
-
Contaminated food
-
Person-to-person contact, especially in daycare centers or shared households
Symptoms typically appear 1–3 weeks after exposure and may include:
-
Watery or greasy diarrhea
-
Bloating and gas
-
Abdominal cramps
-
Nausea
-
Fatigue
-
Weight loss
-
Foul-smelling stools
In some people, especially children or those with compromised digestion, symptoms may last for weeks or become chronic. Giardia can also cause malabsorption, leading to deficiencies in fat-soluble vitamins and lactase intolerance.
When to see a doctor:
If diarrhea lasts longer than a few days, is accompanied by dehydration, fever, or weight loss, or if you’ve recently traveled or consumed untreated water, consult a healthcare provider. Diagnosis is confirmed through stool testing.
Natural Remedies
Stay Hydrated: Replace fluids with electrolyte-rich drinks to avoid dehydration.
Low-Fat, Low-Fiber Diet: Helps ease symptoms by reducing fat malabsorption and bloating.
Probiotics: May help restore gut flora balance and reduce recovery time.
Avoid Sugar and Dairy: These can worsen symptoms by feeding the parasite or aggravating temporary lactose intolerance.
Good Hygiene: Prevent spread by washing hands thoroughly and disinfecting surfaces.
