Giardia or Giardiasis is a parasitic infection of the gut. It is caused by a microscopic parasite called Giardia lamblia. Giardiasis, along with amebiasis and leptospirosis, is an increasingly common waterborne disease that causes severe diarrhea, stomach cramps, and weight loss. These infections are contracted through water contaminated with human or animal fecal material.  Giardia is prevalent throughout the world but is more common in developing countries where water sanitation is poor.[3] [4] [5] Standard treatment is parasitical drugs, but chronic and resistant strains of giardia are now growing. If you want to know how to treat giardia naturally, then fear not. Our home remedies for giardia are proven against this infection.  [1] [2]

how to treat giardiaGiardia Symptoms in humans

G. lamblia is found in animal and human fecal matter. These parasites can survive for a long time in contaminated soil, water, and food. Contact with the bacteria can lead to an infection. [6] [7]

The most common cause of giardiasis is contaminated water. Contaminated water can be from swimming pools, lakes, and even spas. Other sources of the parasite include diapers, animal farms, and agricultural runoffs.

Exposure to G. lamblia through food is less common because the heat kills the bacteria. Eating food rinsed with infected water or poor handling of food can expose you to the parasites.

Giardiasis can also spread via personal contact. For example, unprotected intercourse may pass on the infection. You may also get it from children especially if you work at a daycare center. [8] [9] [10]

The infection is rarely fatal and the immune system should cope. The symptoms of giardia are similar to many other intestinal infections. These include:

  • diarrhea
  • flatulence,
  • greasy stools
  • abdominal cramps
  • bloating
  • weight loss

Vomiting and fever are a less common symptom, and blood-tinged feces are equally uncommon, but certainly possible.

Illness can last several months if untreated and is characterized by continued diarrheal symptoms. With chronic illness, malabsorption of fat, lactose, vitamin A, and vitamin B can occur as chronic diarrhea causes nutrients to be consistently lost.
