Glucomannan as a supplement has been used to treat constipation. Other things that have been known to help relieve constipation are prunes. Prunes contain hydroxyphenyl isatin, a chemical that stimulates the bowel muscles and works as a very gentle laxative. Prunes are an excellent source of soluble fiber, which also helps prevent constipation which helps reduce cancer (particularly colon cancer) risk. Prunes have heart-protecting value as well.
Their soluble fiber helps reduce levels of plaque-producing LDL cholesterol, and their high potassium content regulates blood pressure. Prunes are rich in iron and contain good amounts of niacin, beta-carotene, and vitamin B6, along with copper and boron, making them essential for regular as well as irregular times. The causes of constipation can be insufficient dietary fiber intake, dehydration, medications, hypothyroidism, lead poisoning, stopping smoking, tumors, and lactose intolerance.
There are some great fiber supplements that you can get to help get you regular. Some of the treatments include enemas, eating more fruits and vegetables and dietary fiber, a lot of water and periodic colon cleanses would be great as well. Routine use of laxatives is not a good idea because your bowel action can become dependent on their use.
