My GI doctor wants me to ingest frozen Vaseline for diverticulosis. The theory is that the vaseline will fill in the pouches and prevent infection and flare-ups. Have you ever heard of this? I am 65 years old and have had three major bouts of diverticulitis since 2006 . I 2007 I had a sigmoid collectomy and did not have a flare until 2011 when I was hospitalized for 17 days and on IV antibiotics for 2 months.
