Colorectal Diseases

Could my metal allergy cause diarrhea?



I have allergic reactions to any oxidizing metal, including zinc. I have learned to be careful about my pants buttons, eyeglasses, jewelry, and the host of other metal objects that I encounter on a day-to-day basis. For the past few years, I have been experiencing diarrhea regularly. I was wondering if the presence of metals like zinc in many foods could be a factor in this, and if so, is there anything I can do about it?


Any allergy can cause diarrhea, due to a release of histamine. Not sure if there is anything to do except avoid exposure. Ask your allergist to be sure.
