> [...] the treatment, which involved a bowel cleanse and daily transplants of fecal microbiota over a period of seven to eight weeks
Maybe I'm misinterpreting what the process of that daily transplant looked like, but I expect they ate a not insignificant amount of hospital food if there were 7-8 weeks of daily treatments.
Ya, the word "transplants" here seems to mean something very different than you're interpreting it as.
This isn't a hospital procedure like an organ transplant. It's material placed into the recipients colon through an enema, nasogastric tube or possibly even just taking some pills.
So it might range from done at home to done during a 30 minute visit to a clinic.
I know it's nothing on the scale of an organ transplant, but (other than pills) those things would still lead to the patients being at the hospital. And with frequent enough visits to a hospital, you would probably eat at least some meals there. That's all I meant (and said).
I didn't realize it was such a protracted process, but even if it's a long series of daily treatment, they aren't going to admit you for that if it can be done outpatient. You will be admitted if it's a risky enough procedure that it requires extended/overnight observation. If you can safely go home and come back the next day that is what they will ask you to do.
