ANATOMY

Detailed explanation-1: -Holding in poop causes constipation in part because you are using your anal and rectal muscles to push the stool back into the colon (large intestine). When this happens, all the water that was inside the stool (which is what makes it easier to pass) comes out of the stool, and the stool becomes dry and hard.

Detailed explanation-2: -Diarrhea causes you to lose even more fluids. You also lose salts and minerals such as sodium, chloride, and potassium. These salts and minerals affect the amount of water that stays in your body. Dehydration can be serious, especially for children, older adults, and people with weakened immune systems.

Detailed explanation-3: -Diarrhea happens when stool passes through the large intestine too quickly. Constipation occurs when stool passes through the large intestine too slowly. Bowel incontinence is a problem controlling your bowel movements. Other abnormalities with bowel movements may be a sign of a digestive problem.

Detailed explanation-4: -The most common cause of diarrhea is the stomach flu (viral gastroenteritis). This mild viral infection most often goes away on its own within a few days. Eating or drinking food or water that contains certain types of bacteria or parasites can also lead to diarrhea. This problem may be called food poisoning.
