Hi,
Thanks for posting your query.
With the available describes symptoms, there appears to be high possibility of decreased gastrointestinal motility.
Persisting
constipation may cause injury to colon mucosa with blood loss in stools.
Other possibility could be
inflammatory bowel disease and
colon cancer.
You should consult with internal medicine specialist/
general surgeon and should go for thorough check up.
You should also go for
complete blood count, blood sugar, serum electrolytes, and thyroid profile.
You should take plenty of water, high fibre diet and laxatives containing lactitol and isapgula.
You should perform increased physical activity to maintain gastrointestinal mobility.
You should also go for colonoscopy for better clarification of lower gastrointestinal tract.
You should also take proton pump inhibitors along with prokinetics.
Take care,
Dr. Mayank Bhargava
