Adequate amount of water not being consumed during meals
Suppressing the urge to evacuate whenever it occurs
Indiscriminate and untimely eating
For digestion, a minimum amount of moisture is required when food is eaten. Often, because not enough water is taken along with the meal and this causes harness of stools resulting in constipation.
Suppressing the urge to evacuate when it occurs causes the stools to harden and lose much of the moisture which facilitates normal evacuation. Defecation of hardened stools is a painful experience. No wonder constipation results.
Indiscriminate eating interferes with systematic digestion and inadequately digested portions of food eaten clog the intestines. The hard, incompletely digested food does not get easily evacuated. As a result constipation occurs.
To give an example, Tamarind is usually stuffed in gunny bags. Because of the compressible nature of tamarind, sometimes over-stuffing of tamarind bag is possible. But it will be very difficult to remove tamarind now from the bag. Indiscriminate stuffing of our stomach also results in much the same kind of congestion.
