Small intestinal bacterial overgrowth (SIBO) happens when an excessive amount of micro organism, often coliforms, develop within the small gut. Coliform micro organism ferment carbohydrates, which regularly result in symptoms like extra gasoline, bloating, belly ache, and diarrhea.
The concept behind the SIBO food regimen is to take care of intestine well being by consuming meals which can be much less more likely to ferment within the gut and feed coliform micro organism.
Whereas SIBO is initially handled with antibiotics, “we expect that the food regimen will stop the micro organism from coming again,” says Mark Pimentel, MD, director of the Medically Related Science and Expertise program and affiliate professor of gastroenterology at Cedars-Sinai well being group.
There was comparatively little analysis performed on the SIBO food regimen, but it surely has many overlaps with the low-FODMAP diet, which has extra scientific backing as a therapy for gastrointestinal points.
Here is what you have to know concerning the threat of growing SIBO and the way the SIBO food regimen might help.
Meals to keep away from on the SIBO food regimen

On the SIBO food regimen, you should not eat:
- Any form of sugar alcohol — these are sometimes present in “sugar-free” merchandise and sometimes finish with “ol” like sorbitol

- Mushrooms
How efficient is the SIBO food regimen?
Although there’s much less printed scientific proof for the SIBO food regimen’s effectiveness in comparison with the low-FODMAP food regimen, Pimentel recommends that SIBO sufferers ought to select the SIBO food regimen after taking
“The FODMAP food regimen is studied much more, however has some dangers due to the restrictive nature,” Pimentel says, including that staying on the low-FODMAP food regimen for greater than 3 months can put you in danger for malnutrition.
Pimentel advises that individuals shouldn’t attempt to observe the food regimen on their very own, and may all the time work with a health care provider. Whereas folks with situations like IBS or SIBO typically really feel higher when consuming highly-restrictive diets, they might hurt their general well being of their effort to keep away from signs. “Being below the steerage of a dietitian is the right technique to do it in order that you do not fall into the traps of the diets,” says Pimentel.
If one spherical of antibiotics and the SIBO food regimen do not work to do away with SIBO signs, it’s possible you’ll must do a number of programs of antibiotics, Pimentel says. If there may be an underlying condition like
diabetes
or an obstructed bowel inflicting SIBO, it’s possible you’ll develop recurrent SIBO and you’ll need to deal with the bigger downside or commonly take programs of antibiotics.
