Why does alcoholic cardiomyopathy cause nocturia?

Alcoholic cardiomyopathy is a condition in which excessive alcohol consumption leads to poor heart muscle functioning, resulting in an increased risk of developing cardiovascular diseases. Symptoms include shortness of breath, fatigue, swelling of the lower extremities, and nocturia (frequent urination at night).

Nocturia occurs because the weakened heart muscle prevents adequate blood flow throughout your body and is unable to pump large enough amounts of fluid from the legs back into circulation. This causes fluid accumulation and pressure buildup around your organs—in particular your bladder—which triggers frequent urination during sleep, as well as other urinary tract problems like incontinence and urgency. The amount of fluids eliminated during nocturnal urination may vary from only a few drops to almost full capacity depending on the severity of damage caused by alcoholic cardiomyopathy.

In addition to reducing alcohol consumption or abstaining altogether if possible, it is important that you seek proper medical attention for any symptoms related to alcoholic cardiomyopathy so that your doctor can evaluate the extent of the damage done and provide appropriate treatments such as diuretics or medication targeted towards improving cardiac performance.
