Even higher risk of kidney problems has been found for heavy drinkers who also smoke. Smokers who are heavy drinkers have about five times the chance of developing CKD than people who don’t smoke or drink alcohol to excess. Free radicals (also called reactive oxygen species [ROS]) are one of the by-products of alcohol metabolism and are known to cause cellular damage, unless the body can use antioxidants to clean them up.

Like the kidneys, the liver plays an important role in maintaining acid-base balance. Liver diseases—including alcohol-induced liver problems—disrupt this function and can contribute directly or indirectly to a wide range of acid-base disturbances. Most of the metabolic reactions essential to life are highly how to identify liberty caps sensitive to the acidity (i.e., hydrogen ion concentration) of the surrounding fluid. The kidneys play an important role in regulating acidity, thereby helping determine the rate at which metabolic reactions proceed. Alcohol can hamper the regulation of acidity, thus affecting the body’s metabolic balance.
Kidney Diseases and AUD: Lessons From Epidemiology
Alcohol-induced urination reduced the subjects’ plasma volume, resulting in an increased concentration of plasma sodium. In addition, the subjects’ blood pressure and plasma potassium concentration decreased. These changes in fluid volume, electrolyte balance, and blood pressure may have stimulated the activity of hormones to return body fluid volume and composition back to normal, which occurred soon after consumption. Clinical studies of hypertensive patients have demonstrated that reducing alcohol intake lowers blood pressure and resuming consumption raises it. Although the mechanisms responsible for these effects have not been established, an experimental study by Chan and Sutter (1983) offers some insight.
The NKF explains that chronic drinking can cause liver disease, which impairs the rate of blood flow to the kidneys. Drinking alcohol can affect many parts of your body, including your kidneys. A little alcohol—one or two drinks now and then—usually has no serious effects. For people with chronic kidney disease (CKD) who are having dialysis or on a low-potassium and/or low-phosphate diet, choosing suitable drinks, especially those containing alcohol can be particularly challenging. You probably know someone who developed health problems from drinking too much alcohol. Alcohol can impact many different parts of the body, but most commonly it damages the liver and can lead to a condition called cirrhosis.
Drinking alcohol if you already have kidney stones may cause them to move quickly. According to the NKF, individuals who have sustained an alcohol-induced AKI may require dialysis, depending on severity. Dialysis is a procedure that involves filtering waste products and excess fluid from the blood. According to a 2022 review, symptoms do not usually manifest until stage 4 or 5 of the disease.
This is especially likely if your liver is impaired due to alcoholism. The disease can also affect blood flow to the kidneys and cause them to be less effective in filtering blood. Although the mechanism of alcoholic myopathy is not fully understood, it is likely that disruption of mitochondria-related energy homeostasis is important in promoting muscle cell (myocyte) injury (Eisner et al. 2014). Evidence also exists that alcohol-related damage to the liver, in particular advanced liver cirrhosis, leads to hepatorenal syndrome (HRS)—a deterioration in renal function related to impaired circulation. The underlying mechanisms involved in the development and progression of HRS are incompletely understood, although it is plausible that the altered balance between vasoconstrictor and vasodilator factors plays a significant role (Lenz 2005).
These new drugs should dramatically facilitate treatment of cirrhotic patients with impaired fluid handling. Try swapping out alcoholic drinks for alternative beverages such as juices and teas. Coconut water, apple cider vinegar drinks, and hot chocolate are great options.
- Severe or recurring kidney infections may require hospitalization or surgery.
- Alcohol consumption apparently leads to excessive phosphate levels by altering muscle cell integrity and causing the muscle cells to release phosphate.
- The kidneys play an important role in regulating acidity, thereby helping determine the rate at which metabolic reactions proceed.
- Although hepatorenal syndrome often ensues after an event that reduces blood volume (e.g., gastrointestinal bleeding), it also can occur without any apparent precipitating factor.
- As the plasma filtrate passes along this channel, the substances the body needs to conserve are reabsorbed into an extensive network of capillaries that wrap the nephron tubule.
- Similarly, clinicians long have noted significant kidney enlargement (i.e., nephromegaly) in direct proportion to liver enlargement among chronic alcoholic2 patients afflicted with liver cirrhosis.
It is not known whether chronic alcoholic patients experience a similar difference in the ADH response as they age, however. In the absence of ADH, segments of the kidney’s tubule system become impermeable to water, thus preventing it from being reabsorbed into the body. Under these conditions, the urine formed is dilute and electrolyte concentration in the blood simultaneously rises. Although increased serum electrolyte concentration normally activates secretion of ADH so that fluid balance can be restored, a rising blood alcohol level disrupts this regulatory response by suppressing ADH secretion into the blood. One of the main functions of the kidneys is to regulate both the volume and the composition of body fluid, including electrically charged particles (i.e., ions), such as sodium, potassium, and chloride ions (i.e., electrolytes).
What does kidney pain from alcohol feel like?
When your liver isn’t functioning well, it can impair blood flow to your kidneys. “Liver disease can have significant impacts on the kidneys,” says Dr. Bobart. Drinking alcohol to excess is linked to several health problems, including whats in whippets liver disease and an increased risk of some cancers (not to mention risks from drunk driving or accidental injuries while intoxicated). For people with kidney disease who are having dialysis or on a low-potassium and/or low-phosphate diet, alcohol can be particularly challenging. Kidney dietitian Nick McAleer from Royal Devon and Exeter NHS Foundation Trust offers advice about choosing drinks. Based on the most recent scientific evidence, if you stick to one standard alcohol drink each day (one 1.5-oz shot, one 12-oz. glass of beer or one 5-oz. glass of wine), you do not increase your risk of developing kidney disease.
The traditional hypothesis holds that the kidneys of cirrhotic patients retain sodium in response to ascites that develops when liver dysfunction causes blood vessels to expand beyond available plasma volume (i.e., the “underfill” theory). In contrast, the “overflow” theory postulates that ascites follows when the kidneys retain sodium in response to signals sent by a dysfunctional liver to expand plasma volume. The answer to this version of the “chicken-and-egg” question remains to be elucidated. Chronic alcohol consumption may cause both fluid and solutes to accumulate, thereby increasing the overall volume of body fluids.
The link between alcohol use disorder (AUD) and kidney injury is intriguing but controversial, and the molecular mechanisms by which alcohol may damage sun rock strain the kidneys are poorly understood. Epidemiological studies attempting to link AUD and kidney disease are, to date, inconclusive, and there is little experimental evidence directly linking alcohol consumption to kidney injury. However, studies conducted primarily in other organs and tissues suggest several possible mechanisms by which alcohol may promote kidney dysfunction. One possible mechanism is oxidative stress resulting from increased production of reactive oxygen species, which leads to an excessive amount of free radicals, which in turn trigger tissue injury and increase inflammation. 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.
Major clinical features of hepatorenal syndrome include a marked decrease in urine flow, almost no sodium excretion and, usually, hyponatremia and ascites. Blood urea nitrogen (BUN) levels and serum concentrations of the waste product creatinine are somewhat elevated, but rarely to the degree seen in patients with end-stage kidney failure when kidney disease is the primary disorder. Judgments based on such relatively modest BUN and serum creatinine increases often underestimate kidney dysfunction in patients with hepatorenal syndrome, however, because malnourished cirrhotic patients tend to have low levels of urea and creatinine.
Five Drugs You May Need to Avoid or Adjust if You Have Kidney Disease
Alcohol can perturb these controls, however, to a degree that varies with the amount of alcohol consumed and the particular mechanism’s sensitivity. Of the 48 gallons of filtrate processed through the nephrons of the kidneys each day, only about 1 to 1.5 quarts exit as urine. During this filtering process, substances are reabsorbed or secreted to varying degrees as the filtrate passes through the distinct segments of the nephron tubule.
Both of these factors affect hormones that regulate kidney function, just as changes in fluid volume and electrolyte balance do. Kidneys that have been overworked due to excess alcohol consumption don’t function properly. This makes them less able to filter blood and maintain the correct water balance in the body. The hormones that control kidney function can also be adversely affected. Without adequate blood flow, the kidneys struggle to remove waste products and excess fluid from the blood.
