It is true that many years (30+) went by after the initial diagnosis of diverticular disease before any problems.
It is possible to live with diverticula unless infection sets in ..
Many people don't know they have them
It is the current technology which produces information sometimes incidental to the condition being investigated.
It is good to have plenty of soluble fibre which can be found in a good diet, things like oat bran , oat meal etc.The Scots have the right idea start the day with a bowl of porridge oats or oatmeal of some kind.
The present GI prescribed Mucillium for me which has made a big difference.
In the early years a low fibre diet was recommended but subsequent thinking changed
this to high soluble fibre. Mostly I have eaten whatever I wanted but only had to change some things because of the crohn's.
For many years I never worried about it never crossed my mind at all and life went on till crohn's reared its ugly head. Then so many investigations and attacks., various treatments for crohn's including remicade .Now in remission---no more meds--- next thing surgeryfor a right side adenoma.(polyp)
I would agree that diverticulosis in itself is not a cause for doing anything different., unless infection becomes a problem.All those years I never even thought about it., and lived a pretty healthy life.Best to leave then alone unless otherwise indicated.
A diverticulum is a weakness in the bowel wall that causes a bulge...and can allow for infection since the flow of normal fluids does not reach them .
Seas tar....It most certainly is not a reverse polyp .
A polyp is a growth of tissue usually benign but which must always be removed because of the propensity for some to become malignant.
This is the reason for colonoscopies of healthy people to find the polyps and remove them before there is any chance of malignancy.They can be silent killers.
A polyp grows like a mushroom on a stalk, but there are different types which are not always easy to remove, some are flat,and sessile these are the difficult ones to remove.
I would agree with you to forget what you saw on the report, it most likely will not cause a problem.
Try to increase your soluble fibre, which may also help the crohn's.
Feel better soon
