Studies historically have shown that alcohol consumption markedly increases magnesium excretion in the urine and may affect magnesium levels in other ways as well. For example, when rats are given alcohol, they also require significant magnesium in their diets, suggesting that alcohol disrupts absorption of this nutrient from the gut. Investigators have speculated that alcohol or an intermediate metabolite directly affects magnesium exchange in the kidney tubules (Epstein 1992). Several mechanisms may contribute to abnormally low phosphate levels (i.e., hypophosphatemia) (see box). Simply lacking an adequate amount of phosphate in the diet is one possible reason for phosphate deficiency.

As a consequence, oxidative stress not only propagates kidney failure, but it also contributes to the progression of chronic heart failure (Pacher et al. 2005) and leads to a vicious cycle in alcohol-induced cardiovascular complications. The impact of alcohol on kidney function has not been well investigated. There are several possible protective mechanisms of alcohol on kidney function.

According to the United Kingdom’s National Health Service (NHS), a person should consult a doctor if they experience symptoms consistent with kidney disease. As the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDKD) explains, the kidneys contain tiny, finger-like structures called nephrons. These filter waste products from the blood and maintain the balance of water and minerals in the bloodstream. This article describes how alcohol may harm the kidneys and considers the level of alcohol consumption necessary to cause harm. The current study enrolled 45,200 subjects, which was a representative cohort for the Taiwan population.

More than two drinks a day can increase your chance of having high blood pressure. Alcohol can cause changes in the function of the kidneys and make them less able to filter your blood. In addition to filtering blood, your kidneys do many other important jobs. 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). The kidneys continuously perform their tasks of purifying and balancing the constituents of the body’s fluids.

3For a person weighing 150 pounds, this dose would be roughly equivalent to 17 drinks. 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. See your doctor to treat kidney stones or a kidney infection if they are the cause. People with alcohol-induced CKD will require treatment for AUD as well as CKD. Sometimes, AKI can resolve over time if a person makes sure to stay hydrated. Individuals who are concerned about their drinking habits can also consult a doctor for guidance on professional help and support.

1. Typically, chronic alcoholic patients are losing up to 1.5 g/d of phosphate through their urine when they have reached the point of being sick enough to accept hospitalization.
2. The overactivation of RAAS further aggravates oxidative stress in chronic alcoholism (Ungvari et al. 2004).
3. This may lead to renal corpuscle and glomeruli atrophy and reduced glomeruli volume [8].
4. These filter waste products from the blood and maintain the balance of water and minerals in the bloodstream.

“Normal” urine flow rate is 1 milliliter per minute (i.e., approximately 1 to 1.5 L/day), but this rate can vary widely, depending on water intake or dehydration level, for instance. Alcohol causes changes in the function of the kidneys and makes them less able to filter the blood. Alcohol also affects the ability to regulate fluid and electrolytes in the body.

According to the World Health Organization (WHO), there is no so-called “safe” level of alcohol consumption, and the more alcohol a person drinks, the greater their risk of health issues. For people with diabetes and CKD, alcohol may be safe to drink if you have your blood sugar level under control. Remember that alcohol on an empty stomach can cause blood sugar levels to drop. Additional ingredients in mixed drinks may also add carbohydrate that must be considered. 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.

Kidney Structure and Function

People who drink too much are more likely to have high blood pressure. More than two drinks a day can increase your chance of developing high blood pressure. Drinking alcohol in these amounts is a risk factor for developing a sign of kidney disease, protein in the urine (albuminuria).

Another study by Plotnikov and colleagues (2009) showed that mitochondria isolated from rat kidneys were damaged by oxidative stress when incubated with myoglobin. This finding suggests that rhabdomyolysis and myoglobin toxicity may trigger oxidative stress in the kidney via mitochondrial injury. Substantial evidence exists to support the concept that kidney failure in hepatorenal syndrome is not related to structural damage and is instead functional in nature. For example, almost 30 years ago, Koppel and colleagues (1969) demonstrated that kidneys transplanted from patients with hepatorenal syndrome are capable of resuming normal function in recipients without liver disease. 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. In many patients with liver cirrhosis, the kidneys’ ability to create dilute urine is compromised, leading to a state of abnormally low sodium concentration (i.e., hyponatremia).

Kidney Disease Cookbooks

Their analysis included 20 studies representing a total of 292,431 patients. In fact, IgA glomerulonephritis—acute inflammation of the kidney caused by an IgA immune response—is one of the most common types of primary glomerulonephritis worldwide (D’Amico 1987). This IgA-related kidney disease leads to clinical symptoms of renal injury and eventually progresses into renal failure (Amore et al. 1994; Bene et al. 1988; Pouria and Feehally 1999). Experimental studies suggest that heavy alcohol consumption induces IgA kidney disease (Smith et al. 1990).

Treatments for acute kidney injury

Ethanol and polyphenol both have anti-oxidative effects and ethanol improves polyphenol absorption, thereby contributing to bioavailability [4,5,6]. Furthermore, alcohol has an anti-inflammatory effect, with increased serum interleukin-10 levels and decreased serum interleukin-16 levels [20]. Alcohol consumption can raise high-density lipoprotein cholesterol concentration [21,22], improve insulin sensitivity [23], and reduce platelet aggregation rate and fibrinolysis [21,22].

Frequent urination that goes along with this flushing of the system can lead to dehydration. This can interfere with the functioning of the kidneys and other organs. Regular and excessive alcohol use can also cause high blood pressure (hypertension) for a combination of reasons, such as disrupting hormones and affecting the muscles in blood vessels. A 2018 smash mouth liver failure study found that having alcohol use disorder increased the likelihood of having a new diagnosis of CKD. However, the study authors also mentioned that more studies are needed to explore the connection between AUD and kidney function.

These disturbances increase the kidneys’ workload in restoring acid-base balance through formation of an acidic or basic (i.e., alkaline) urine. For instance, the opposite of respiratory alkalosis can occur when a person becomes extremely intoxicated. Because alcohol is a central nervous system depressant, it may slow the rate of breathing as well as reduce the brain’s respiratory center’s sensitivity to carbon dioxide levels.

In many cases, control mechanisms govern the rate of reabsorption or secretion in response to the body’s fluctuating needs (see table for a summary of the body processes influenced by key electrolytes). Under the influence of antidiuretic hormone (ADH), for example, the tubules can create either a concentrated urine, to discharge excess solutes and conserve water, or a dilute urine, to remove extra water from body fluids. In the absence of ADH, when body fluids drinking because of boredom are overly dilute, the kidneys dilute the urine, allowing more water to leave the body.

In the univariable Cox model, it may not meet the proportional hazard assumption. Not only the univariable analysis, but also the non-proportionality, may affect the multivariable model. This 13-year cohort study revealed that participants with social or regular drinking habits had significantly reduced risk of the development of CKD when compared with non-drinkers. Ethanol administration in rats showed maverick house sober living particular alterations in the renal antioxidant system and glutathione status [4,5].
