Neurogenic Bowel Dysfunction
The primary reason behind constipation in MS is the previous — the event of neurogenic bowel dysfunction, says Vargas.
That is brought on by demyelination in nerves that assist with the operate of intestine management. Because of this, the colon strikes stool extra slowly, the muscle groups of the pelvic flooring might not work accurately, and it may turn into troublesome to totally empty the bowels, she says.

Individuals not consuming sufficient fiber are prone to have smaller stool quantity, slower colonic transit, and elevated straining.
