Constipation in the elderly can be solved by adjusting diet, physical therapy, lactulose, methylcellulose and other medications. 1. Adjusting diet: when the elderly suffer from constipation, they can intervene by adjusting their diet, eating more vegetables and fruits as well as coarse grains to increase dietary fiber, which will make the feces softer and easier to be discharged out of the body. 2. Physical therapy: hot compresses and massages on the abdomen of the elderly can speed up gastrointestinal motility and reduce the time of feces retention in the body, so that the feces can be easily discharged. 3. Drug treatment: when the effect of diet adjustment and physical therapy is not good, you can follow the doctor’s instructions to give methylcellulose, bisacodyl enteric-coated tablets, lactulose, glycerin enema and other drugs to deal with. If the constipation of the elderly is serious, it is recommended to go to the hospital in a timely manner to exclude organic lesions, so as not to delay the condition. The above drugs need to be applied under the guidance of a physician, and should not be used without authorization.
