Treatment of the Lock:

The lock, as a rule, is a temporary problem. The patient has to know that it is necessary to drink enough water every day, to regularly carry out physical exercises and there are products with the high content of soluble and insoluble fibers. Soluble fibers include pectin; insoluble fibers include bran from grain, such as wheat and oats. Fresh fruit and vegetables contain as soluble and insoluble fibers. Dietary consumption of cellulose should be increased gradually, along with increase in water consumption, for obtaining soft effect.
It is recommended to children:
1. To small children - 60-120 ml of fruit juice (grapes, a pear, apple, cherry, prunes) twice a day.

If changes in a diet are not enough for elimination of locks, within several days it is possible to use a purgative. Drugs which soften a chair and add volume (for example, bran) works more slowly, but it is safer, than salt or grass purgatives on the basis of Senna or a buckthorn which can do harm to the nervous device and a mucous membrane of a large intestine. The patient who feels abdominal pains, nausea or vomiting should not give laxative. Laxative drugs should not be used during the long period as dependence can develop.
