Alcohol is a toxic substance that can damage the body’s organs and tissues. There are mixed conclusions about whether or not alcohol causes kidney failure specifically. 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. We used the Chi-Square test to compare patient’s demographics and baseline comorbidities between patients with alcohol use disorder and the control cohort.
- Individuals who are concerned about their drinking habits can also consult a doctor for guidance on professional help and support.
- 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.
- However, as alcohol consumption can lead to adverse events, such as hypertension, cerebral hemorrhage, alcohol addiction, and tendencies toward violence, clinicians should not advise non-drinkers to start drinking.
- However, alcohol consumption can have negative effects on the body and should generally be avoided if you want to keep your kidneys healthy.
- Although research suggests several potential mechanisms by which alcohol may directly or indirectly affect the kidneys, they have not yet been validated experimentally.
- Scientists are not sure whether an association exists, and they are unsure as to the underlying mechanisms.
Alcohol’s Role in Impaired Kidney Function and Kidney Disease
The kidneys are hard at work on any given day in a healthy person, but the kidneys of a heavy drinker work overtime. A heavy drinker is defined as a woman who drinks more than seven times a week or a man who drinks more than 14 times a week. People who maintain this kind of drinking habit are at double the risk for developing kidney disease compared to the general population, including moderate drinkers.
- A compromised diluting ability has important implications for the management of patients with advanced liver disease.
- 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.
- These new drugs should dramatically facilitate treatment of cirrhotic patients with impaired fluid handling.
- Methanol poisoning can cause abdominal pain, visual disturbances, central nervous system damage, and death.
- Specifically, drugs known as arginine vasopressin antagonists are being developed to inhibit ADH at the cell receptor level.

Gonwa and Wilkinson (1996) reported a 4-year survival rate of 60 percent in hepatorenal syndrome patients who received a liver transplant, which constitutes a major step forward, considering the previous uniformly fatal course of the disease. AKF works on behalf of 1 in 7 Americans living with kidney disease, and the millions more at risk, to support people wherever they are in their fight against kidney disease — from prevention through post-transplant living. According to the NKF, one potential symptom of AKI is flank does alcohol affect your kidneys pain, which is pain in the side of the back, between the ribs and hips. To reduce harm to a person’s health, it is best to reduce or avoid consuming alcoholic drinks where possible. Our kidneys filter waste and toxins from our blood, regulate blood pressure, and maintain overall well-being. While substance abuse is often cited as the primary cause of kidney issues, medical experts have explained that kidney problems can also stem from a combination of factors such as genetics, poor diet, or inadequate hydration.
Treatments for acute kidney injury
The association between increased blood pressure and alcohol consumption has been recognized at least since 1915, when Lian reported the prevalence of high blood pressure (i.e., hypertension) in relation to the drinking habits of French army officers. Chronic alcohol consumption may cause both fluid and solutes to accumulate, thereby increasing the overall volume of body fluids. In turn, such expansion of body fluid volume can contribute to high blood pressure, a condition often seen among chronic alcoholic patients. Normally the rate of blood flow, or perfusion, (i.e., hemodynamics) through the kidneys is tightly controlled, so that plasma can be filtered and substances the body needs can be reabsorbed under optimal circumstances (see sidebar). Established liver disease impairs this important balancing act, however, by either greatly augmenting or reducing the rates of plasma flow and filtration through the glomerulus.
Threats to the normal functioning of the kidneys are serious medical problems, and alcoholism is a contributing factor to kidney disease. The American Cancer Society suggests that no one should drink alcohol due to its harmful effects on the body and its potential to increase your risk of cancer. If you’ve already been diagnosed with cancer, drinking alcohol could also affect your risk of developing a new cancer.
Alcohol Misuse and Kidney Injury: Epidemiological Evidence and Potential Mechanisms
The primary function of the kidneys is to remove waste products and excess fluid from the body. Kidneys are responsible for maintaining a healthy balance of water and electrolytes in the body. Your kidneys also control the production of red blood cells, produce vitamin D, release hormones to regulate blood pressure, and remove drugs from the body. One example of an alcohol-related acid-base disturbance already has been mentioned in relation to low levels of phosphate (i.e., respiratory alkalosis resulting from hyperventilation during alcohol withdrawal). Other acid-base disturbances are possible as a result of excessive alcohol consumption.
Independent Student’s t test was used for analyzing continuous variables. We estimated the hazard ratios (HRs) and 95% confidence intervals (CIs) for CKD by univariate and multivariate Cox proportional-hazards regression models with stratification based on gender, age, and comorbidity. We adjusted the variables of age, gender, comorbidities and NSAID use in the multivariable models. We used Kaplan-Meier method to calculate the cumulative incidence of CKD.
Another potential cause of hypophosphatemia in alcoholic patients is hyperventilation, which can occur during alcohol withdrawal. Prolonged rapid, shallow breathing results in excessive loss of carbon dioxide and decreased blood acidity (i.e., alkalosis), which in turn activates an enzyme that enhances glucose breakdown. In glucose breakdown, phosphate becomes incorporated into various metabolic compounds, ultimately lowering blood levels of phosphate. As the rate of glucose breakdown increases, profound hypophosphatemia potentially can result. Although fluid overload—not alcohol itself—is considered the major contributor to beer drinkers’ hyponatremia, alcohol does appear to directly influence the kidney’s handling of sodium and other electrolytes, potentially resulting in hypernatremia. In a study by Rubini and colleagues (1955), subjects who consistently drank about 4 ounces (oz) of 100-proof bourbon whiskey experienced decreased sodium, potassium, and chloride excretion (i.e., increased retention of solutes).
Alcohol Consumption Can be a “Double-Edged Sword” for Chronic Kidney Disease Patients
- However, based on the study conducted by Saunders et al. [42], we assume the amount of alcohol drinking in AUD is more than 60 grams per day for men and 40 grams per day for women.
- The overactivation of RAAS further aggravates oxidative stress in chronic alcoholism (Ungvari et al. 2004).
- It is possible that the contradictory findings are the result of varying effects of different types of alcoholic beverages on the kidney, or the result of different alcohol consumption patterns in different countries.
Alcohol is a toxic substance that can cause dependence alongside a range of other negative health effects.
