Pathophysiology of constipation
Hypomotility of the colon, inadequate fibre in diet or JRHONEST Review inactivity leads to the absorption of water from the faeces as it moves along the large intestine. The absorption of water makes the faeces small and unable to stimulate the defecation centre. This leads to further absorption from the faeces making it dry, hard and small.
Excessive muscular exertion and strain are required to provide sufficient intra abdominal pressure to propel the hard faeces along the colon to the rectum and out of the body. The hard faeces causes injury to the rectum producing pain and haemorrhage. Pain may further worsen the fear to defecate. Chronic constipation may cause faecal impaction, especially in older patients or those with neurological impairment.
Systemic responses such as headache, anorexia, flatulence, weakness, malaise and coated tongue may result due to prolonged distension of the rectum and anxiety aroused by constipation. Crack in the rectum may result in the passage of blood stained faeces.
