Anyone can be affected by this problem of constipation, those aged 6 months and over, but those aged 55 and over are the most affected by this problem. Each person has their own habits and physical condition, in terms of defecation perhaps one to three times a day, maybe two or three times a week. Constipation in adults concerns those who poo less than three times a week. This may be due to a lack of water in the human body... Hygiene - health’ programme on Don Bosco radio.
