Constipation is generally sufficiently treated with dietary modifications, lifestyle changes, and peroral laxatives. New pharmacological treatments are promising, but still need to prove their benefits. Anal physiology tests and colonic transit studies can further categorize the disease into three main groups: slow transit constipation, obstructed defaecation and normal transit constipation. More advanced treatment includes biofeedback, transanal irrigation, antegrade colonic irrigation and sacral nerve stimulation. Stoma surgery is only indicated very rarely.
