Effective medications for constipation include volumetric laxatives, stimulant laxatives, osmotic laxatives, lubricating laxatives, and enemas.
1. Volumetric laxatives: for example, methylcellulose, which is used to absorb water in the intestines to help defecation.
2. Stimulant laxatives: e.g. Bisacodyl, Senna, etc. They are used to promote peristalsis and contraction of the intestines and can only be used for a short period of time.
3. Osmotic laxatives: such as lactulose, polyethylene glycol, etc., can help the liquid penetrate the intestinal wall and increase the water inside the intestine.
4. Lubricating laxatives: e.g. paraffin oil, etc., which can make the stool pass through the intestine easily.
5. Enemas: sodium phosphate, soapy water, etc., which can soften the stool and help it pass.
If constipation occurs, it is recommended to drink enough water every day. Patients with kidney failure or heart failure should consult their doctor to determine the amount of rehydration solution, and if medication is needed, it is recommended to consult your physician and take the medication as prescribed by your doctor.
