Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
During defecation, excessive stressing may lead to decreased cardiac output due to increased intra thoracic pressure that lead to sweating. In cardiac failure patients stressing lead to
profuse sweating. Autonomic neuropathy may lead to sweating as well. Defecation
syncope may also present with sweating.
Also you may be suffering from altered bowel movements due to
inflammatory bowel disease (IBS) resulting in altered consistency that leads to greasy stools. Until examination is done it is difficult to say what it is.
Avoid spicy food, alcohol,
smoking and caffeinated drinks. Please get stool examination is done; also check your blood sugar and cardiac function status. Avoid
constipation by high fiber diet and regular exercises.
If symptoms do not improve please consult your doctor he will examine and treat you accordingly.
I hope I have answered your query. Let me know if you have any further questions.
Regards,
Dr. Penchila Prasad Kandikattu
