Mineral oil for treating constipation


Mineral oil is often used as a laxative. For this purpose, the oil can either be taken by mouth or in the form of an enema. Mineral oil helps in treating constipation in two ways:

  • By retaining the moisture in the stool.
  • By acting as a lubricant.

The mineral oil coats the lining of the intestines and prevents the excess absorption of moisture from the stool which prevents it from becoming hard. It also lubricates the intestines and helps easy removal of the hardened stool.

Mineral oil is generally safer as compared to any other laxatives. When consumed by mouth, it can initiate a bowel movement in 6-8 hours, while an enema can work in just 12-15 minutes.
