@lobotomize-me - Reuteri yogurt is a very good suggestion. I have been making it since Nov 2023. I have it for breakfast.
@gg12 - There are videos on YouTube describing how to make the Reuteri containing yogurt. Search YouTube for "SIBO yogurt".
The theory behind how and why it works for SIBO is that pharmaceutical antibiotics can permanently disrupt the balance of bacteria in the GI tract and the naturally occurring reuteri that resides in the small intestine is one of the bacterial species that is permanently lost (along with other species). The imbalance of bacteria creates a situation that allows bacteria that normally only reside in the colon and large intestine to spread or "overgrow" into the small intestine, thus the term SIBO (small intestinal bacterial overgrowth).
The reuteri yogurt reintroduces the lost species and some balance is restored. Digestive issues associated with the imbalance are resolved within about 30 - 45 days. Unfortunately, if you stop eating the yogurt the digestive issues return over time.
