What is constipation?
Constiption is the infrequent passagge of hard, dry stools. The colon absorbs water and salts from the contents of the bowel. If too much water is absorbed then the contents become hard and dry, leading to constipation. If too little is absorbed then the contents remain fluid and can you can suffer diarrhoea. At the extreme end of the constipation spectrum is fecal impaction, a condition in which stools harden in the rectum and prevents the passage of any stool.
Constipation can also alternate with diarrhoea. This pattern is more commonly considered as part of the condition Irritable Bowel Syndrome (IBS).

Treatments for Constipation
Laxatives are used to treat constipation. Over the counter laxatives are usually classed according to their mode of action.
Stimulant laxatives such as senna and bisacodol, increase the speed at which the contents move through the bowel.
Osmotic laxatives such as lactulose, macrogol and magnesium sulphate, work by drawing water into, or retaining it in the bowel, so softening the stools.
Docusate sodium is a stool-softening agent which works by a surfactant action, breaking up stools and allowing them to be passed. Glycerin suppositories have a direct softening effect.
Bulk-forming laxatives such as bran, Isphagula husk, methylcellulose and sterculia, Take longer to exert an effect. The addition of bulk to the stools makes them softer and easier to pass. This type of product is often recommended for patients with Haemorrhoids or Irritable Bowel Syndrome.
