Can Alcohol Cause Urinary Retention?

Quick answer

We found no official health page that lists alcohol as a cause of urinary retention. NIDDK says retention comes from a blockage or from a bladder that cannot push out all the urine. If you cannot urinate, get medical care promptly.

What NIDDK says causes retention

NIDDK says urinary retention results from either a blockage that partly or fully stops urine flow, or a bladder that lacks enough force to expel all the urine. It can be acute (a sudden inability to urinate) or chronic (a gradual failure to empty the bladder fully).

Symptoms

NIDDK says symptoms range from severe abdominal pain and the inability to urinate to few or no symptoms at all. MedlinePlus, describing blocked urine flow, lists a weak stream or trouble starting, dribbling, feeling the bladder is not empty, less urine output, and blood in the urine.

Where alcohol fits

Neither NIDDK nor the MedlinePlus page we read mentions alcohol as a cause. Medical case reports may describe retention after heavy drinking, but we did not use them as a source and cannot give you a rule from them. Alcohol can also interact with some medicines, so mention your drinking to your doctor if you are being treated for bladder or prostate problems.

What to do

  • If you cannot pass urine, or have severe belly pain, seek urgent medical care.
  • If you have a weak stream or often feel you have not emptied your bladder, see a doctor.
