Giardiasis is an infection of the small intestine caused by an insidious parasite called Giardia Lamblia. A protozoa that often contaminates water it spreads via contaminated water, soil, animals, contaminated food, direct human contact and household pets. It lives in the intestines and is passed in the faeces. The parasite has a hard outer shell which means that they can survive for long periods of time and contaminated water is generally a likely source for picking up the parasite. Symptoms usually appear 1-2 weeks (but may take longer) after infection and most people are able to eradicate it from the body within 6 weeks if addressed appropriately.


  • diarrhea
  • weight loss
  • vomiting
  • bloody stool
  • gas and flatulence
  • stools which float and are greasy
  • ineffective digestive processes
  • cramps
  • halitosis (bad breath)
  • nausea
  • leaky gut

Any diarrhoea that persists beyond five days warrants examination of the stool for evidence of parasites such as Giardia. It is best to err on the side of caution when it comes to digestive illnesses and have a stool analysis performed so that you know exactly what you are dealing with and not guessing as to what the cause may be. If left untreated intestinal parasites may cause further complications to health such as allergies, digestive conditions, liver congestion, bowel ailments, chronic dehydration and depressed immunity. A sample of blood, stool, urine or phlegm may be analysed for the presence of parasites in the body.


A parasite is an organism that lives off of or inside another organism, called a host, during all or part of its life. This is a type of symbiotic relationship in which the parasite needs the host in order to live to obtain nourishment. Many organisms, including some plants, animals, spiders, crustaceans, bacteria, and worms, are considered parasites. Many parasites can enter the human body via the skin and mouth and when the larvae reach the intestines and develop into adults, mild or moderate symptoms may begin to occur.
