Did you know? Symptoms related to small intestinal bacterial overgrowth (SIBO) often overlap with symptoms of thyroid disease, and studies show that up to 50 percent of those with hypothyroidism may have SIBO!
Once you have SIBO, it can lead to intestinal permeability and contribute to a long list of digestive symptoms.
Conditions like IBS, hypothyroidism, fibromyalgia, and restless leg syndrome have all been tied to SIBO.
SIBO can also cause a depletion of vitamin B12 and iron, as well as lower levels of digestive enzymes like lactase (which digests lactose in dairy) and amylase (which digests starch), making it more difficult to digest many foods.
If you’ve noticed that fibrous foods, fermented foods, histamine-containing foods, prebiotics, cruciferous veggies, and/or the use of probiotics seem to cause a flare-up in your digestive symptoms, there’s a good chance you have an overgrowth of bacteria in your small intestines. That is because these foods feed the bacteria in your intestines and cause them to multiply, contributing to the overgrowth.
Do you - or does someone you know - have symptoms of SIBO?
