black watery diarrhea melena upper GI bleeding emergency management

⚠️ This is a Medical Emergency — Call Emergency Services (911) Now

Black watery stool is called melena. It is caused by digested blood from bleeding in the upper gastrointestinal (GI) tract — typically the esophagus, stomach, or upper small intestine. This is a potentially life-threatening condition that requires immediate emergency care.

What to Do RIGHT NOW

  1. Call 911 (or your local emergency number) immediately — do not wait and do not drive him yourself if he is weak or dizzy.
  2. Do not give him food, water, or any medications until he is evaluated.
  3. Keep him lying down and calm.
  4. Watch for these danger signs that mean the bleeding is severe:
    • Dizziness or fainting
    • Rapid or weak pulse
    • Pale, cold, or clammy skin
    • Confusion or unresponsiveness
    • Vomiting blood (bright red or "coffee grounds" appearance)

Why This Is Serious

When blood travels from a bleeding source in the upper GI tract (stomach or duodenum), it gets digested along the way, turning the stool black and tar-like (melena). The most common causes include:
  • Peptic ulcer (stomach or duodenal ulcer) — most common cause
  • Esophageal or gastric varices (dilated veins, often from liver disease)
  • Gastritis or esophagitis (inflammation)
  • Mallory-Weiss tear (a tear from vomiting)
  • Stomach or esophageal cancer
According to Harrison's Principles of Internal Medicine (2025), melena indicates an upper GI bleed and requires urgent endoscopic evaluation and resuscitation.

Ask These Questions While Waiting for Help

  • Is he taking aspirin, ibuprofen (Advil/Motrin), naproxen, or blood thinners (warfarin, aspirin, clopidogrel)? These can cause or worsen GI bleeds.
  • Does he have a history of stomach ulcers, liver disease, or alcohol use?
  • Has he vomited blood or felt very faint?
  • How long has this been going on?
Please call emergency services immediately. Black tarry stool is never normal — it always means there is blood somewhere in the digestive tract, and it can become life-threatening very quickly if not treated.

He was admitted to hospital for 3 days. Now he has come home but he only has lassi and water and sometimes bread. But still he has diarrhea he is saying something watery paper like and then he said something black watery dairrhea is thr

melena black stool after hospital discharge GI bleeding recurrence warning signs

⚠️ He Needs to Go Back to the Hospital — Today

Black watery stool after being discharged for GI bleeding means the bleeding has likely returned (rebled). This is a known and serious complication. The 3 days in hospital were not enough to resolve it, or something has triggered it again.

This is NOT normal post-discharge diarrhea

  • "Watery paper-like" stool = intestinal lining is irritated and not absorbing properly
  • Black watery stool = blood is still (or again) passing through his digestive tract
  • Lassi (yogurt drink) will not stop a GI bleed

You Must Go to the Emergency Room Right Now Because:

  1. Re-bleeding after a GI bleed has a mortality rate of up to 30% — it is not something to wait out at home
  2. He needs a repeat endoscopy to find and stop the source of bleeding
  3. He may need IV fluids, blood transfusion, or medications that cannot be given at home
  4. His gut is clearly not healed — only liquids and bread + still bleeding = his body is in distress

Danger Signs to Watch for on the Way

Take him immediately if he has any of these:
  • Feeling faint or actually fainting
  • Very fast or very weak heartbeat
  • Pale face, cold sweat, clammy skin
  • Confusion or not making sense
  • Vomiting blood (red or dark "coffee ground" color)
  • Stomach pain getting worse

What to Tell the Hospital Doctors

  • "He was discharged 3 days ago for GI bleeding / melena"
  • "The black stool has returned at home"
  • Tell them what medicines (if any) were given on discharge
  • Tell them if he takes aspirin, ibuprofen, blood thinners, or steroids
Please do not wait until morning or the next day. Take him to the emergency room now. Black stool = active or recent blood in the gut. The hospital needs to assess him again tonight.
