Besides, constipation can be caused by physical injury and systemic diseases, such as high fever infection status, postoperative blood loss, stroke, diabetes, thyroid disease and Parkinson’s disease. Other reasons for constipation include problems in intestine, for examples, lesions of the rectum and anus, rectal and anal stenosis as well as intestinal obstruction or diverticulitis
Mint has been used for hundreds of years as a health remedy. Peppermint oil might help with irritable bowel syndrome -- a long-term condition that can cause cramps, bloating, gas, diarrhea, and constipation -- and it may be good for headaches as well. More studies are needed to see how much it helps and why. People use the leaf for other conditions, too, but there’s very little evidence it helps with any of them.
