Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
Recent change in bowel habits at this age warrant colonoscopy
examination to rule out any malignancy. However it may be normal but is should be done. Meanwhile take lots of fruits, vegetables and liquid in your diet. May add psyllium
fibres. If not relieved then take a laxative like syrup cremaffin
I hope I have answered your query and this will help you. If you have any further query I will be happy to answer that too. Remain in touch and get-well soon.
