Hi.. Thanks for the query.. The symptoms of constipation that has not gone in a week can be due to causes like sudden changes in dietary habits, excess intake of antacids, irritable bowel syndrome, excess intake of dairy,eating disorders, lack of appropriate physical activity, side effects of medicines, Hypothyroidism etc.. I would suggest you to consult a Gastroenterologist and get evaluated and he can advise you get investigations done like Colonoscopy, Barium swallow, hormonal assy etc to confirm the cause.. Treatment of the cause can relieve the symptoms.. You can also be advised to take laxativs like Polyethylene glycol [Miralax], castor oil also acts as a lubricant and laxative.. You can also be advised to take Psyllium husk or Lactulose.. Take more fibres in diet, plenty of water and do moderate workout.. You can also be advised medications like Lubiprostone or Linaclotide.. Hope this helps.. Regards.
