Emeran A. Mayer, MD, provides expert commentary in Well + Good - July 2023

Researchers recently flew the fecal samples of 37 Buddhists from monasteries high in the Tibetan mountains to a lab in Shanghai. The purpose for this high-altitude journey? To see how the composition of the monks’ samples — markers of their gut health — differed from that of their neighbors. The researchers wondered if the monks’ daily meditation practices might have an impact on the microbiome. “If relaxation and stress reduction and meditation decrease sympathetic nervous system tone and reactivity, then I think that will be the most possible explanation for changes in microbiome,” states Dr. Mayer, professor of medicine, physiology and psychiatry.

UCLA GI dietitians prompt multidisciplinary task force to offer comprehensive treatment for dysautomia - May 2023

UCLA Health’s newly assembled dysautonomia task force makes UCLA one of just a few places on the West Coast that offers comprehensive treatment for the illness. Nancee Jaffe, MS, RDN, lead GI dietitian, and her colleagues noticed they were getting many referrals for patients diagnosed with dysautonomia. “We kept ending up with patients who were either coming straight to us or they were going to a gastroenterologist, getting diagnosed with irritable bowel syndrome, and ended up with us,” Jaffe says. “However, we knew there were other things going on when they would talk about their blood pressure dropping or having trouble breathing. We reached out to cardiology and neurology and that’s how we ended up building this task force,” Jaffe explains. “Now, we have a team of over 20 doctors, dietitians and nurses at UCLA. Before, these patients didn’t have a referral network. Now we are that referral network.” Read UCLA Health addresses post-pandemic emergence of illnesses affecting the autonomic nervous system.
