Types of Constipation
1. Atonic Constipation
Atonic (Gk. atonos = unaccented, without tension) constipation results from reduced muscle tone (tension) of the colon, abdominal wall or pelvic floor. Causes include:
- Habits, like sedentary life style, irregular meals, low-fiber diet, postponing bowel movement, overuse of laxatives resulting in a lazy colon that does not react to stimuli, like eating and presence of the stool in the rectum. Affected person simply does not feel the urge to defecate even when his colon is full of stool.
- Loose rectal muscles, mainly in old people
- Weak pelvic floor muscles, often in women after giving birth
- Damage of the intestinal nerves in long-term, poorly controlled diabetes or congenital disorders, like Hirschsprung’s disease.
Change of life habits, or surgery (in Hirschsprung’s disease) can help.
