Blurb about it!

Giardiasis is an infection in the small intestine that spreads through contact with infected people. This condition is common all over the world, according to the Centers for Disease Control and Prevention (CDC). However, it tends to be more common in developing countries due to lack of water quality control and sanitary conditions.

In this article, we break down the causes, symptoms and treatments of Giardiasis Lamblia:


The common symptoms of giardia lamblia include: 

  1. Bloating or excessive gas
  2. Increased exhaustion and fatigue
  3. Spontaneous lactose intolerance (occurs 20 to 40% of the time) 
  4. Excessive diarrhea
  5. Quick weight loss
  6. Stomach pains and cramps
  7. Loose and pale faeces as a result of diarrhea and weakening. Will float down the toilet. 


Giardia lamblia is caused by Giardia duodenalis, a parasite that is often found in animals such as sheep, dogs, cattle, and cats. The disease is spread to humans via contact with faeces or contaminated water. The parasite has to be ingested via the mouth. Hence, drinking contaminated water is the most probable cause for giardia lamblia. 


While giardia lamblia is an intense disease, treating it is not that difficult. The treatment involves taking in the right antibiotics on a set pattern. The antibiotic dosage is decided based on the condition and intensity of the infection, and consuming antibiotics can help you get rid of the giardia lamblia within just a few days.
