Giardiasis: Causes, Symptoms, Treatment

Giardiasis is a parasitic infection caused by the Giardia intestinalis protozoan. The parasite infects the small intestine of humans and animals and is transmitted through the ingestion of contaminated food or water. The infection is most commonly found in areas with poor sanitation.

Causes of Giardiasis

Giardiasis is caused by the Giardia intestinalis protozoan. The parasite is found in contaminated water, food, and soil. The infection is most commonly spread through the ingestion of contaminated water, which can happen when drinking from untreated sources such as rivers and lakes or when swimming in contaminated water. The infection can also be spread through contaminated food, such as raw or undercooked meat or vegetables that have been fertilized with contaminated soil. Additionally, the parasite can be spread through contact with contaminated surfaces, such as diaper changing stations, bathroom fixtures, and doorknobs.

Symptoms of Giardiasis

The symptoms of giardiasis can vary from person to person and may range from mild to severe. Common symptoms include:

• Diarrhea
• Abdominal pain
• Bloating
• Gas
• Nausea
• Fatigue
• Weight loss

Symptoms may begin to appear 1-2 weeks after infection and can last for several weeks or months if left untreated. Some people may not show any symptoms at all but can still transmit the infection to others.

Treatment of Giardiasis

Giardiasis can be treated with a medication such as Entamizole Syrup. Treatment usually lasts for 5-7 days and can be repeated if necessary. In severe cases, hospitalization may be required to provide intravenous fluids and electrolytes.
