I had a really bad flare up about 5 years ago that caused a small tear in my intestines. The dr. wanted to do a resection on my intestines and then put in a colostomy bag until I could get rid of the infection. I really really did not want a colostomy bag and asked him if there was a chance that the tear could heal itself without surgery and he told me that the only way that that would have a chance of working was for me to go on a liquid diet but even then the chance was small. He wasn’t wild about it but I really did not want that bag. I basically went on an liquid diet for 14 days while being monitored in the hospital. The tear healed and with large doses of antibiotics I was able to beat the infection. After I got out of the hospital I started to fast for 24hrs once a week, more if I felt the signs of a flare up coming on. It has been 4yrs since my last flare up and I am able to maintain a healthy weight.
I also have diverticulitis and believe fasting is a great way to help with diverticulitis. I don’t think you can cure it, but it can certainly help once you start to feel the symptoms. Essentially, you are just letting you intestines/colon to rest and heal. The clue if times I have had it, it took about 2 days of fasting and it went away.
Another with Diverticulosis here.
To be honest, while I feel like fasting definitely isn’t the only way to prevent or ease a flare-up, it definitely is the best way.
If I feel a flare up coming on (its a pretty distinctive pain in a pretty specific part of my abdomen) I start to fast immediately. If I don’t eat anything solid from the moment I start to feel that tinge of pain, it doesn’t progress past that and usually is gone in 1 or 2 days.
So to answer your question, yes. Fasting is incredible for diverticulosis/itis. The Aloe Vera drinks seem to help for me personally too, plus they’re tasty.
