This mass makes faeces heavier and simpler for digestive system muscles to transport. Thus, frequent bowel motions lessen constipation risk. Fibre absorbs water in the digestive tract, moistening faeces. This softens faeces for easy intestinal passage. It prevents constipation-causing dry, hard stools.

Fibre also keeps the digestive tract healthy. It regulates digestion, avoiding diarrhoea and constipation. Fibre slows digestion, improving nutritional absorption. Fibre feeds helpful intestinal flora as a prebiotic. These bacteria are essential for digestive health and immunological function. Fibre promotes healthy bacteria development, which is crucial for digestive health.

b. Prevents/Treats Constipation: Constipation causes infrequent bowel motions and difficulties moving faeces. Increased fibre consumption helps prevent and relieve constipation, which is linked to low fibre intake. As you said, insoluble fibre prevents and treats constipation.

This non-soluble fibre bulks stool and promotes regular bowel motions. It speeds digestion like a natural laxative. Insoluble fibre from whole grains, cereals, and vegetables (particularly those with edible skins and seeds) adds roughage to the stool.
