Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain dry mouth cab be a side effect of taking Laxatives and a long term continuous intake known as Laxatve abuse can further cause
constipation instead of relieving..
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 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..
For dry mouth you can chew sugarfree chewing gum, drink plenty of water and also suck tart candies..
Hope this information helps..
Thanks and regards.
