Colon hydrotherapy can cause microscopic tears or introduce bacteria into the bloodstream, so doctors monitor vital signs, labs, and possibly imaging post-cleanse to catch early infection or sepsis risk. There are several factors to consider; see below for details on risk factors, warning signs, and when to seek medical help.
This brief overview covers key points, but the complete information below contains critical details that could impact your next steps and healthcare journey.
