Explanation:
Water is important for your digestion because it keeps the food you eat moving through your intestines.
Your intestines also need water to help keep stools soft and easy to pass. All feces contain water, causing water loss during a bowel movement.
A person typically loses about 6% of its water through feces.
This means it's not constantly losing water, a process like urination and breathing makes us lose more water than digestion.
