1 doctor agrees

In brief: Sometimes it does

Constipation by itself can increase one's weight by the amount of poop (stool) that is staying inside the intestines.
Hormonal imbalances, such as low thyroid hormone, can cause both constipation and weight gain. If one tries to treat constipation by eating more fruits or drinking more juice, the large amount of fruit sugar will lead to weight gain. Persistent constipation needs a doctor's exam.

In brief: See below

You can hold up to 18 lbs of stool.
..But does stool make you gain fat no...The weight of stool is a factor in just weight! use a stool softener.
