Constipation, Diarrhea, and GI Bleeding: anatomy, treatment, and risks

This guide supports an informed conversation with a surgeon. Recommendations must be individualized after examination and review of relevant records.

Related anatomy

The digestive tract moves and absorbs food from the esophagus through the stomach, small bowel, colon, rectum, and anus.

Pathophysiology

Bowel changes and bleeding can result from medication effects, functional disorders, inflammation, infection, vascular disease, polyps, cancer, or anorectal conditions.

Diagnosis and evaluation

Evaluation may include history, examination, blood and stool tests, imaging, EGD, or colonoscopy.

Medical and nonsurgical treatment

Management depends on findings and may include diet or medication changes, treatment of inflammation or infection, iron replacement, surveillance, or referral to another specialist. Endoscopy can diagnose disease and sometimes treat it during the same procedure.

Surgical and procedural treatment

Treatment targets the cause and may include medication, diet changes, endoscopic treatment, or surgery for selected disease.

Risks and tradeoffs

Endoscopy risks are uncommon but can include sedation complications, bleeding, perforation, aspiration, infection, missed lesions, post-polypectomy syndrome, dental injury with upper endoscopy, and the need for additional treatment.

Recovery and shared decisions

Recovery depends on the exact procedure, disease severity, health, work demands, and whether additional treatment is needed. Before treatment, discuss expected pain control, wound care, activity, diet, pathology results, follow-up, and the symptoms that should prompt a call.

  • Ask what alternatives are reasonable.
  • Ask how success and recurrence are measured.
  • Review medications and health optimization.
  • Clarify expected restrictions and follow-up.

Urgent care: Call 911 or seek prompt evaluation for severe or rapidly worsening pain, heavy bleeding, trouble breathing, repeated vomiting, fainting, rapidly spreading redness, or another emergency.
