Hi.
Thanks for your query.
Noted the history not full emptying of the bowel, needs to drink tea 2 times in the morning and have to sit for 30 minutes for bowel movement. Tried many remedies.
The possible causes can be IBS that is
irritable bowel syndrome.
Descending perineal syndrome.
Habituation and as per the body clock setting.
I would advise you the following:
First of all to get the Saline+water enema and send the sample of stool for tests for 3 consecutive days.
Tests of blood for sugar and
liver function tests along with the routine.
Ultrasonography of the abdomen and
CT scan if required.
Per-rectal digital examination, proctoscopy and
colonoscopy by appointment can help.
If a cause is found , get treated.
If the tests are negative, think if IBS as a cause.
Also, you have to make a list of the foods and beverages that cause the problems and stop them altogether.
