Thank you for the query.Magnesium Citrate
can be used only for temporary constipation
relief. It is very important to find the reason of constipation. If you are older than 50, colon cancer
should be ruled out at first. It can be a reason of constipation. Moreover, colon cancer can give constipation and diarrhea alternately. Hot and sweaty feeling can be caused by sudden blood pressure drop, low glucose blood level or low hemoglobin
level due to bleeding.
Other possible reasons of constipation are diet (low fiber intake and mineral water intake), hypothyroid, medicines (ca-blockers, antidepressants).
I suggest you to visit your doctor as soon as possible. Blood work should be done at first. Stool tests and colonoscopy
should be next.
Hope this will help.
