Irritable Bowel Syndrome (IBS)

A common disorder of the large intestine, believed to be suffered by between 1 and 2 in 10 people in the UK. The condition typically causes pain in your stomach, bloating, and a change in your bowel habits, somethings alternating between bouts of diarrhoea or constipation. There's no cure but you can buy Xifaxanta without a prescription for IBS to help ease the symptoms.

Small Intestinal Bacterial Overgrowth (SIBO)

This is a disorder of excessive bacterial growth in the small intestine. Unlike the colon (or large bowel), which is rich with bacteria, the small bowel usually has fewer than 104 organisms per millilitre. Patients with bacterial overgrowth typically develop symptoms including nausea, bloating, vomiting, diarrhoea, malnutrition, weight loss and malabsorption.

How does Xifaxanta work for IBS and SIBO?

In the body, the active ingredient of Xifaxanta (Rifaximin)is not absorbed into the bloodstream, which minimises potential side effects whilst increasing its ability to act directly on the bacteria that exist within the small intestine.

Many health experts believe that those with IBS/SIBO may have changes in their intestinal microorganisms, and that by targeting these gut microorganisms to treat the condition, symptoms could dramatically improve.

Even better is that unlike other antibiotics, Xifaxanta has minimal impact to the large intestine, thereby reducing the risk of giving you gastrointestinal symptoms or yeast infections.
