Hello, The amount of severe constipation is matter of concern as that strain is putting extra efforts of heart to pump more and raising heart problem concern as well. There can be narrowing of part of large bowel, tumor, developing malignancy or other pathology of the intestines which may be responsible for loss of microscopic amount of blood on daily basis and causing development of anemia condition. In my clinic, after thorough clinical and per rectal examination, I do recommend a complete hemogram and colonoscopy report for looking into the depth of diagnosis and further guidance accordingly. Till that time, following will help you: - Plenty of liquids - High fiber diet - Prefer easily digestible food stuffs as rice, dal, curd, organic fresh fruits - Avoid smoking or alcohol if using - Avoid opioid or other abuse substances if using - Regular walking, aerobics - Control of body weight - Bulk forming laxatives as Ispaghula or Psyllium husk Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel, General Surgeon
