My dh also ended up in the hospital on IV antibios...he now takes psyllium fiber every day and no problems since.

Have you been to a gastroenterologist? Are you current with getting colonoscopies?

I get a flare up about once a year. Usually when I do something "stupid",for me, like eating too many seedy items like berries or not chewing nuts well. I have been able to fight off infection except once when I needed antibiotics. The worst was when I got sick several hundred miles away from home and had to drive back doubled over with pain,fever and chills etc. For me it's a careful diet avoiding too much of the wrong kind of fiber. I do try to increase my fiber with grains and vegetables that are not seedy etc..It seems to help. I also take an Imodium 2 to 3 times a week to keep my IBS under control. That helps too since it slows down the digestive tract to add bulk and water. Twice a week seems to be the right dosage for e unless i am having an episode. Then I take a 3rd pill. It's trial and error. This has made it easier for me to live my life. Others need a different program of self help or medical intervention.

joann, your gastro specialist and primary care physician should direct you with the ideal treatment and diet for you. What's good for one may be dangerous for another.

I do. There is a medication that works fantastic. It's weird how mine works: I can eat a handful of peanuts, but not a handful plus a few. I'll double over with pain for days and nothing will work. A pharmacist gave me 3 little pills (I wish I could remember what they're called) and it cleared it right up after just one pill. Now I just watch what I eat and hope for the best. It doesn't happen very often anymore. (knock on wood: have a container of salted peanuts in my locker at work and snack on them)

I have...brought on by overeating popcorn !

Saw the NP today. She gave me antibiotics as usual. I really don't know what to do. I have flare-ups every few months or more.

“Saw the NP today. She gave me antibiotics as usual. I really don't know what to do. I have flare-ups every few months or more.”

Is the NP part of a gastroenterologist group? If not, you really need to change and see a specialist. Having flare ups that often can lead to bigger problems, including surgery. Did the NP at least give you suggestions for diet and liquid intake?

Neither a nurse practitioner nor a physician's assistant is a substitute for a physician. And a crappy physician can sometimes be a poor substitute for a good one.

I'll see a nurse practitioner or physician's assistant when I have something seasonal and obvious (sore throat, possible flu, cold) when a real doc isn't available. But not otherwise. Never.

joann, don't you have access to better medical resources? You need something more thoughtful and intelligent than "take these pills and call again if the problem continues".

I try to avoid nuts, popcorn and fatty/greasy foods. Take Psyllium husks daily. Works pretty well.

Edited to add: I only eat meat a couple of meals a week and rarely anything fried.

what type of Psyllium husks do you take? Does it bloat & gas you?

I take a heaping Tbs of Yerba Psyllium husks stirred into a few ounces of water every evening. You may need to experiment to find the right dose. Too much will result in bloat.

like maddilee and Elmer, I suggest it's time to get an appointment with someone else. Doing the same thing over and over and expecting a different result, isn't that the (tongue in cheek) definition of insanity?

I don't know diverticulitis, but antibiotics can wreak havoc on your body's microbiome. Has your health professional discussed probiotics with you? Are you keeping a detailed food diary?

My sympathies to you -- I know what it's like to experience recurring gut pain. Hang in there.

I know your pain- I have Crohns disease.

Nothing fatty, greasy or with seeds or nuts is a good start -be careful with the dairy products too.
