10 Early Signs and Symptoms of Multiple Sclerosis

Bowel and bladder problems

Problems with your bowel and bladder can happen because MS lesions may block or delay nerve signals in parts of the central nervous system that control the bowel, bladder and urinary muscles. Symptoms of bladder dysfunction may include incontinence; having to urinate frequently, urgently, or at night (nocturia); and the inability to empty your bladder completely. Bowel problems may include constipation and diarrhea.
