Most concerning possibilities:
Alcoholic gastritis / esophagitis — Heavy drinking severely irritates the stomach lining and esophagus. Inflammation near the diaphragm can trigger the hiccup reflex relentlessly.
Pancreatitis — Acute pancreatitis is a classic and dangerous complication of alcohol binges. The inflamed pancreas sits near the diaphragm and vagus/phrenic nerve pathways. This can be life-threatening.
Hepatic encephalopathy — In someone with likely years of alcohol damage, the liver may be failing to clear toxins. When ammonia builds up in the blood, it affects the brain and central nervous system — intractable hiccups can be a neurological symptom of this.
Esophageal varices or GI bleeding — Chronic alcohol use causes portal hypertension, which leads to fragile blood vessels in the esophagus. Bleeding or irritation there can drive hiccups.
Central nervous system cause — Hiccups originating in the brain (stroke, mass, infection) are less common but must be considered, especially with alcohol’s effects on blood pressure and clotting.
Aspiration pneumonia — Someone on a bender who has vomited is at real risk of inhaling stomach contents. Lung irritation near the diaphragm can cause persistent hiccups, and this infection can be severe.
Bottom line
Consecutive days of unrelenting hiccups in this clinical picture is not a quirk — it is his body signaling that something is wrong internally, likely related to his GI tract, liver, or nervous system.
He needs emergency medical evaluation now. If you have any relationship where you can intervene, this warrants a 911 call or urgent trip to the ER.
