Can low fiber cause cramps? returned from trip of 2 weeks and now i have pretty strong abdominal cramps just before pooping/during pooping. goes away after i'm finished. i know my fiber/water intake have been low. will upping fiber resolve this?

Altered bowel movements are very common after travel. Fiber intake usually isn't involved. Return to your usual diet and activities. See a doctor if the cramps or other symptoms are still continuing after another week or two. If you have diarrhea, don't wait: you might have an intestinal infection, especially if your travel was to a developing country or other setting with maybe poor hygiene.

During travel especially air travel can lead to dehydration as well as excessive caffeine/ alcohol intake, change in diet and certainly possibility of food borne infection. Increase your fluids moderate finer intake. If not resolved in 5-7 days or symptoms worsen, see your doctor promptly. Do not do finer alone as this will make things worse.
