Patient question: I am 20 years old, this year into the summer until now, the stool has been abnormal, before also have constipation, but not so long, usually through the use of open plug can be solved, but now sometimes use open plug can not pull the stool, some time ago began to drink Bison source regular tea some effect, but do not drink again began to constipation, how to treat? Immediately stop using all the intestinal tea drugs, these drugs for your “young intestines” is very bad, I recommend you two laxative, first you buy lactulose oral solution (Dumic), constipation, drink 2 bags before bed (15ml per bag), the next morning you can smooth stool, and no harm to the intestinal tract, pay attention to the cultivation of more water If you are still young, you must insist on exercising your bowel habit. If the symptoms of abdominal distension are obvious after taking Dumic orally, use polyethylene glycol 4000 bulk (Fosamax bulking agent), also harmless, feel the need to defecate with 1000 ml of water to flush 2 packets, about 2 hours to defecate, do not use other non-professional guidance of laxatives, there will be side effects, remember, drugs are never the best solution to the problem but only a symptomatic means of solving the pain, usually Pay attention to the regulation of emotions, healthy diet, and good bowel habits is the most important!
