Intestinal Parasites

Intestinal Parasites

It’s common for digestive issues to begin while travelling abroad or after a case of food poisoning while eating out.

This can be a short spell of diarrhoea with cramping, nausea and fever that may be caused by a bacterial, viral or parasitic infection and is most commonly reported when travelling in:

  • Southeast Asia
  • Africa
  • Central and South America

Often the more uncomfortable symptoms subside but general IBS symptoms can remain as a single episode of travellers diarrhoea can increase the risk of IBS by approximately 5 fold.

The Microbiome

Post-infectious IBS

Following a parasitic infection or a case of travelers diarrhoea, the risk of IBS increases.

This may be due to:

  • low-grade inflammation in the digestive tract
  • an imbalance in the bacteria and/or yeast (dysbiosis)
  • a bacterial overgrowth in the small intestine (SIBO)

Gut Health Testing

Understanding the balance of the gut microbiome can be of particular help when dealing with long-term digestive issues. This can allow us to engage in a more targeted approach.

  • Stool testing provides valuable information on the types of bacteria present as well as if parasites are contributing to the overall picture.
  • Following conventional treatment, there can be imbalances or persistent low-grade inflammation in the digestive system.  So even though the offending organism may have been removed, additional repair and rebalancing may be needed.
  • Testing can help direct the most appropriate support. This will come in the form of dietary suggestions and targetted supplements to help rebalance, repopulate, and restore the gut.w
