Hello,
It would be better if you had mentioned your age. There are number of causes of
constipation. Many of them do not need any investigation, however, if it is associated with other features like stomach aches,
fever then it is necessary to investigate for the cause.
Also, if the condition is not improving from the diet, exercise and medication then it is necessary to investigate it. For a situation like this as you have explained, I usually do some of the investigations like
complete blood count,
thyroid function test, serum calcium, serum potassium etcetera. Another test like
colonoscopy may be necessary to exclude the conditions of the bowel.
So do not get worried for now, but if the problem is annoying you can find a doctor and get an examination and the test done.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Harihar Devkota
