Can I do the Lactulose breath test if I am lactose or dairy intolerant? Yes you can.
Many people confuse Lactulose the solution you drink at the beginning of the SIBO Breath tests with Lactose. Lactulose is actually a mixture of galactose and fructose so you should be fine to do the Lactulose SIBO breath test if you are intolerant to Dairy.
The main symptoms of SIBO are Bloating, Diarrhoea and or Constipation, Flatulence, abdominal pain and cramps and in some cases reflux, nausea and fatty stool. In fact research shows that SIBO is responsible for up to 84% of cases of IBS.
SIBO is a complicated condition and is also known to be a factor in fatigue, prostatitis, acne roseacea, restless legs, joint pain, weight gain or weight loss, rheumatoid arthritis, fibromyalgia and many more seemingly unrelated non digestive issues.
A good lab will actually test for both Hydrogen and Methane at the same time.
I have seen many negative hydrogen but methane positive breath tests so it’s really important to test for both so that SIBO isn’t missed.
