Once you start eating healthily and eat foods that contain roughage, like cabbage, prunes, oranges, apples,
oats, pulses, your body should start to work properly again. Doing some form of exercise, even walking can also help to get your bowels to move.
There are also medications that loosen the faeces rather than using laxatives that can be quite harsh and aggravate the anal passage.
Do speak with your doctor because there may be another underlying problem as well possible anaemia.
