Alcohol-Related Internal Bleeding: Mechanisms & Warning Signs

Chronic heavy alcohol use causes internal bleeding through multiple pathways:

Mechanisms

1. Esophageal varices: Cirrhosis → portal hypertension → dilated esophageal veins → rupture (life-threatening hematemesis).
2. Gastric erosions/ulcers: Alcohol damages mucosa, inhibits prostaglandins, increases acid → bleeding.
3. Coagulopathy: Liver fails to produce clotting factors; thrombocytopenia from splenomegaly/marrow suppression.
4. Hypertension: Chronic use raises BP → vascular stress.
5. Pancreatitis: Severe inflammation erodes peripancreatic vessels.

Warning Signs (Seek Emergency Care)

• Vomiting blood or "coffee grounds" material
• Black, tarry stools (melena) or bright red blood per rectum
• Lightheadedness, fainting, rapid heart rate
• Pale, cold skin; confusion

Treatment

Resuscitation (fluids, blood), endoscopy (banding, clipping, glue), vasoactive drugs (octreotide), antibiotics, TIPS for refractory varices. Long-term: alcohol cessation, cirrhosis management.

Alcohol-related bleeding is a medical emergency. Early intervention saves lives.
