Study Summary

African Americans have the greatest burden of hypertension. Recently, the short-chain fatty acid, butyrate, has been reported to have some effect on blood pressure. Butyrate is not normally ingested since it is made by bacteria in the gut as a byproduct of fiber fermentation. In this proof of concept study, the investigators will investigate the effect of butyrate absorbed in the gut (via the participant self-administering an enema with butyrate) has on blood pressure.

Primary Outcome

Immediately following self-administration of butyrate enema, participants will be fitted with an ambulatory blood pressure monitor to be worn for 24 hours.
