Digestion Issues Post Chemo

@primek I too have a small hiatus hernia and am unable to tolerate wheat well however I can eat a true sourdough. Something about how my body digests it more easily. I can also handle spelt flour for the same reason. I am not too good with dairy protein but can handle the lactose.

My gut took forever to settle down. On chemo I had nexium twice a day plus needed zantac in between. (Dissolvable ones are best...script only) It has settled but even 2 years on I need nexium daily.
I have since had a scope and have been diagnosed with a small hernia and barretts oesophagus...which is cell changes from reflux! So I now don't try to do without but feel it's better to take the medication. I've also been diagnosed as completely lactose intolerant now. So knowing that has helped.

Things that helped me.
Taking a proton pump inhibitor daily (such as nexium)
Avoiding really high fat foods like pastries (sausage rolls ...although rarely  eaten are a killer)
Not too many wheat products (no idea why but possibly as they sit in your gut longer ...tested fir intolerances and no issue)
Watching highly acidic foods...some fruits like pineapple etc. I can eat them now but for twelve months I couldn't have strawberries, kiwi, pineapple, capsicum without severe burning. 

Hope  things improve for you soon. 

Thanks for all your awesome suggestions ladies.   :)

Thanks @"Patti J"   That's interesting about what your Onc told you re scoby.  ( have to admit just googled before what Kombucha is made from and saw a pic of the Scoby  )   Mmmm  shouldn't have looked doesn't look the most pleasant. Thanks for your suggestion re pickled ginger.  :) 

Best thing for upset tummies: pickled ginger but not the pink one (food colouring). You can get it at Japanese food shops. 
My oncologist told me not to drink kombucha because of the sediment or SCOBY. She was worried about infection.

@kmakm   Would love to try the kefir.   Where do you get it from Kate.  Also I have never been a milk drinker ( literally gag on the stuff )  But love the natural yoghurt.  Could I mix kefir with say banana to make a smoothy.

Thanks @kmakm   will check out my local shops.  Have been using as much apple cider vinegar as salad dressing as well.

Perhaps work on your gut health? A glass of kombucha everyday and a shot of kefir might help. Kimchi and sauerkraut too. Worth a try.

Thanks @Sister I am also beginning to notice Somac is not working like it used to as well, will swap to Nexium although it worries me being on all of these med's all the time.  I was on sparkling water but went off it I might just start taking again that's a great idea.
How long before your digestive problems improved.

I suffered a lot with digestive issues during chemo which continued well after.  I was on Ativan for nausea which worked really well (but does make you drowsy) and Somac for reflux but that stopped working after a while so I switched to Nexium (20mg).  I found that what I could tolerate changed throughout chemo but pasta worked well for the whole treatment.  I also drank a lot of sparkling mineral water.  I could tolerate hot water, but cold water just seemed to sit in my stomach.  I also found hot milk to be settling.
