Those who have a particularly sensitive stomach will want to avoid eating too many cucumbers, as they have been known to cause problems with diarrhea in those who already have this problem. Due to the fact that they have a high water and vitamin E content, they can in fact exacerbate stomach and diarrhea problems for certain people.

Those who have problems with frostbite and excessive sun exposure can use them as an all-natural remedy though, so that is something to keep in mind. If your stomach is sensitive to certain foods, it would probably be a good idea to avoid eating too many cucumbers because of the problems they have been known to cause.
