Can laxative abuse cause constipation?

  For various reasons, laxative abuse is increasing. Long-term use of laxatives not only leads to “laxative dependence” but also may cause colon lesions and damage the intestinal nervous system, making the colon less dynamic, thus forming laxative constipation.  If a patient has developed “laxative-dependent constipation”, what should be done?  First of all, if the patient feels that the bowel movement is not normal, he/she should go to the hospital for necessary examination and reasonable treatment.  Secondly, diet and living conditioning is also a treatment method that cannot be ignored: 1. Correct bad dietary habits: eat more food with high crude fiber content and develop the habit of drinking more water. 2.
