Several epidemiological studies have shown that mild alcohol consumption benefits cardiovascular health (Coate 1993; Kannel and Ellison 1996) by reducing the risk of coronary heart disease (Mukamal et al. 2006). In contrast, heavy drinking leads to the development of nonischemic dilated cardiomyopathy (Klatsky 2007) and significantly increases the risk of sudden cardiac death (Hookana et al. 2011). Due to the metabolism of ethanol, significant amounts of acetate are produced how does alcohol affect the kidneys and subsequently incorporated into acetyl-coenzyme-A, a molecule that participates in metabolism of proteins, lipids, and carbohydrates. Protein acetylation—adding an acetyl group to a protein—is integral to regulating processes controlled by mitochondria, including fatty acid metabolism and antioxidant defense (Choudhary et al. 2014). This could also be a significant factor contributing to ethanol-induced mitochondrial dysfunction in the kidneys (Harris et al. 2015).
Alcoholic Cardiomyopathy: Another Potential Confounder

2The terms “alcoholic patient” and “alcoholism” as used in this article are summary terms for the diagnoses of alcohol abuse and alcohol dependence as defined variously by the studies cited. The difficulties in successfully managing dilutional hyponatremia have resulted in the recent emergence of a promising class of new drugs to treat this abnormality. Specifically, drugs known as arginine vasopressin antagonists are being developed to inhibit ADH at the cell receptor level. These new drugs should dramatically facilitate treatment of cirrhotic patients with impaired fluid handling.

Alcohol also affects the ability to regulate fluid and electrolytes in the body. When alcohol dehydrates (dries out) the body, the drying effect can affect the normal function of cells and organs, including the kidneys. In addition, alcohol can disrupt hormones that affect kidney function. For instance, a high intake of sugary beverages or high-sodium foods may strain the kidneys (1, 2), potentially leading to kidney damage over time. Drinking too much alcohol—even for a completely healthy person—can cause heart disease, liver disease, high blood pressure and kidney disease, in addition to many other medical problems.
- In addition, AUD’s effect on other major organs (liver, heart, intestines, and skeletal muscle) appears to promote unfavorable pathological processes that are harmful to the kidneys.
- The kidneys are the organs primarily responsible for regulating the amounts and concentrations of these substances in the extracellular fluid.
- The symptoms and severity of a UTI may get worse after drinking alcohol.
- In glucose breakdown, phosphate becomes incorporated into various metabolic compounds, ultimately lowering blood levels of phosphate.
Study participants and data collection
- If you feel a sharp stabbing pain or a dull ache in your back under the ribcage when you drink alcohol, it’s possible that it’s your kidneys or a kidney stone.
- The primary exposure was baseline total alcohol intake divided into four categories.
- Alcohol may indirectly increase the risk of developing a urinary tract infection (UTI).
- In addition, Iwatsuki and colleagues (1973) and Gonwa and Wilkinson (1996) documented the return of normal kidney function in hepatorenal syndrome patients who receive liver transplants.
Additional ingredients in mixed drinks may also add carbohydrate that must be considered. If you do choose to drink alcohol, limit your intake to no more than one to two drinks per day. A drink in this instance is equivalent to a 5 oz glass of wine, 12 oz beer, or a single shot (1.5 oz) of 80-proof hard liquor.

A blockage or obstruction prevents urine from properly draining from the kidney to the bladder. You may experience flank pain and pain or difficulty during urination. A kidney infection is a type of urinary tract infection (UTI) that starts in the urethra or bladder and moves to one or both kidneys. The symptoms and severity of a UTI may get worse after drinking alcohol. Not all forms of kidney disease are preventable, but adopting a healthful lifestyle may reduce the risk of complications, even in people with genetic kidney disorders.
Alcohol Consumption and Risk of Chronic Kidney Disease: A Nationwide Observational Cohort Study
Ensuring no one faces kidney disease alone
- We used data from the National Health Interview Survey (NHIS) in 2001, 2005, and 2009; the National Health Insurance research database; and, the National Deaths Dataset.
- Some of the first signs of kidney damage from alcohol are increased urination frequency, changes in urine, weakness, and fatigue.
- These include anthocyanins, which are the main polyphenols in red grapes, and resveratrol, which is the most famous polyphenolic compound found in red wine [104].
