Possible roles of short-chain fatty acids in the pathophysiology and treatment of irritable bowel syndrome

Table 1 The proportion of the 3 main short chain fatty acids in irritable bowel syndrome patients that received 60 g of the donor’s transplant

SCFAs	Baseline	1 month after FMF	1 year after FMT	2 years after FMT	3 years after FMT
Acetic acid	64	59	60	51	50
Propionic acid	19	18	18	16	17
Butyric acid	17	23	22	33	33

SCFA: Short chain fatty acids; FMT: Fecal microbiota transplantation.

SCFAs	Baseline	1 month after FMF	1 year after FMT	2 years after FMT	3 years after FMT
Acetic acid	62	63	64	65	60
Propionic acid	22	19	18	20	23
Butyric acid	18	18	18	15	17
