Welcome to BS AMA doctors. The have absolutely NO idea what they are doing, and are all about maintaining their 'Billable' treatment hours!
I met with one of our HCP (KP) GI specialist, who actually admitted that they have absolutely NO IDEA how to treat Long COVID. I was prescribed LUBIPROSTONE 8 mcg TID, on 3/24/23. Has not done anything to improve my G.I. issue.

Per Dr. Vanichkachorn “While we are NOT sure yet, there are several POSSIBLE ways the COVID-19 infection could cause gastrointestinal problems,” Dr. Vanichkachorn says. “For example, the lining of the gut has a large amount of the receptors that the SARS-COV2 virus uses to invade cells. The general inflammation caused by the infection can also disrupt the normal bacteria that live in the gut and stimulate some of the gastrointestinal system’s nerves.”
Even Mayo Clinic does NOT KNOW!
