Everything you need to know about this condition
What is Giardiasis [lambliasis]?
Giardiasis, also known as lambliasis, is a parasitic infection that affects the small intestine. It is caused by the Giardia lamblia parasite, which is found in contaminated water, food, and soil. According to the World Health Organization (WHO), giardiasis is a common intestinal infection worldwide, affecting millions of people each year. If you have giardiasis, you may experience symptoms like diarrhea, abdominal pain, and weight loss, which can range from mild to severe.
Causes and Risk Factors
Giardiasis is typically spread through the fecal-oral route, where the parasite is ingested through contaminated water, food, or hands. You are at a higher risk of getting giardiasis if you:
- Drink untreated water from lakes, rivers, or wells
- Eat undercooked or raw foods that may be contaminated
- Have poor hygiene habits, such as not washing your hands regularly
- Travel to areas where giardiasis is common
- Have a weakened immune system
- Are malnourished or have a history of intestinal problems
Signs and Symptoms
The symptoms of giardiasis can vary from person to person, but common signs include:
- Diarrhea, which can be watery or bloody
- Abdominal pain or cramping
- Weight loss
- Fatigue
- Loss of appetite
- Nausea and vomiting
- Bloating and gas In some cases, giardiasis can be asymptomatic, meaning you may not show any symptoms at all. However, if you do experience symptoms, they can range from mild to severe and may last for several weeks or even months.
