A poop transplant — otherwise known as a fecal microbiota transplant (FMT) — may help adults with long-term insomnia sleep better, a small study suggests.
After the transplant, study participants' gut bacteria became more diverse than an untreated group of people with insomnia. Their sleep efficiency, meaning the percentage of time they spent asleep while in bed, also increased, researchers reported July 22 in the Journal of Internal Medicine.
