Alcohol Misuse and Kidney Injury: Epidemiological Evidence and Potential Mechanisms PMC

how alcohol affects the kidneys

Moreover, even if alcohol may help prevent kidney cancer, it can increase the risk of developing other cancers. In particular, studies have shown that alcohol can contribute to liver, breast, and colorectal cancers (28). If you have kidney cancer, it’s best to talk with your doctor about moderate drinking. Your doctor can give you advice about whether it is safe to consume alcohol while undergoing cancer treatment. The risk of developing CKD from heavy drinking also increases if you smoke. Rather than the type of beverage, it is the amount of alcohol that affects the kidneys, with binge or excessive drinking having the most impact.

  • Nowadays, many forms of ethyl alcohol are available, such as beer, wine, vodka, and other spirits, and these have become very popular among adults.
  • Patients frequently fail to comply with their physician’s orders to limit their fluid intake.
  • However, some studies have found that ethanol can directly cause kidney damage, independent of liver damage [28,30,31].
  • It is hoped that future investigations will focus on this important subject area.
  • Since women have a higher blood concentration of alcohol, they may be more sensitive to alcohol than men [3,50,90].

Can drinking cause kidney failure?

In addition, alcohol consumption can contribute to volume overload, hypertension, and electrolyte disorder between hemodialysis sessions in hemodialysis patients, which also should not be ignored. So, alcohol consumption can be a double-edged sword for patients with CKD, and any policy regarding alcohol consumption for them must be very cautious. Unlike previous reports, some researchers indicated that ethyl alcohol pretreatment can improve renal antioxidant activities and capacity. Other research also reported that 5 weeks of ethanol exposure can improve CAT activities in the renal cortex in rats. Nevertheless, before rats received large doses of ethanol in their drinking water, they had a 3-week transition period with low concentrations of ethanol [37].

  • It’s important to understand the reason for your discomfort in case it’s a sign of something serious.
  • 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.
  • Without treatment, a person with an acute kidney injury may have a seizure or go into a coma.

Five Drugs You May Need to Avoid or Adjust if You Have Kidney Disease

Moreover, alcohol-attributable deaths have increased worldwide, making alcohol the fifth leading risk factor for premature death and disability in 2010 and the first among people ages 15 to 49 (World Health Organization 2014). 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. Some observers have noted https://ecosoberhouse.com/ that patients with cirrhosis frequently develop hepatorenal syndrome following hospital admission, possibly indicating that a hospital-related event can trigger the syndrome. Regardless of the precipitating factor, patients who develop kidney failure in the course of alcoholic cirrhosis have a grave prognosis. The events leading to abnormal sodium handling in patients with cirrhosis are complex and controversial, however.

Alcohol consumption and inflammation

The survey questions did not distinguish non-drinkers and former drinkers, and former drinkers were categorized as non-drinkers. Former drinkers are mostly remarkable, as their health status may be worse, and morbidity and mortality are higher than never drinkers [27]. In addition, the beverage type and exact amount of alcohol consumed were not available in the dataset.

In turn, such expansion of body fluid volume can contribute to high blood pressure, a condition often seen among chronic alcoholic patients. 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). Although some exceptions exist, several historical studies have reported similar modest reductions in sodium and potassium excretion following alcohol use. 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.

What Are 3 P’s of Diabetes? Definitions, Prevention, and Treatment

  • By promoting liver disease, chronic drinking has further detrimental effects on the kidneys, including impaired sodium and fluid handling and even acute kidney failure.
  • Alcohol-induced skeletal muscle damage leads to excessive amounts of circulating myoglobin, causing renal tubular injury as a result of increased oxidative stress.
  • This makes it difficult for us to obtain reliable evidence to support our conclusions.
  • But it can also happen if you have other health conditions, including a kidney infection.
  • In order to do their job properly, the kidneys need a certain rate of blood flowing into them; a liver that is damaged by alcohol abuse cannot properly regulate the blood that the kidneys receive.
  • A 2018 study found that having alcohol use disorder increased the likelihood of having a new diagnosis of CKD.
  • According to the National Cancer Institute (NCI), there is a widesperad agreement among scientists that alcohol can cause several types of cancer, like head and neck cancer, liver cancer, colon cancer, and breast cancer.

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 how alcohol affects the kidneys fluid handling. Subjects that were aged more than 18 years old were selected from the 2001, 2005, and 2009 NHIS. Those with a diagnosis of CKD in the medical insurance record before the interview date were excluded.

Even drinking a little too much (binge drinking) on occasion can set off a chain reaction that affects your well-being. Lowered inhibitions can lead to poor choices with lasting repercussions — like the end of a relationship, an accident or legal woes. Each of those consequences can cause turmoil that can negatively affect your long-term emotional health. Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA. Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors. Having a glass of wine with dinner or a beer at a party here and there isn’t going to destroy your gut.

Binge drinking, or drinking numerous drinks in just a few hours, can cause an acute kidney injury. A compromised diluting ability has important implications for the management of patients with advanced liver disease. Restricting the fluid intake of hyponatremic patients eventually should restore a normal fluid balance; unfortunately, this restriction may be difficult to implement. Patients frequently fail to comply with their physician’s orders to limit their fluid intake. Furthermore, clinicians sometimes overlook the fact that fluids taken with medications also must be restricted for these patients and mistakenly bring pitchers of juice or water to their bedsides.

Although research suggests several potential mechanisms by which alcohol may directly or indirectly affect the kidneys, they have not yet been validated experimentally. Future research will hopefully explore these hypotheses to provide a better understanding of alcoholic kidney injury. This article highlights the effects of other organs on kidney and renal function; however, it should be noted that alcoholic kidney injury itself may have negative metabolic consequences. One such complication is impaired vitamin D metabolism (Shankar et al. 2008), which may influence the function of several other organs, creating a vicious cycle. A few studies have linked rhabdomyolysis and myoglobin toxicity with acute kidney injury, supporting a possible association among alcohol use, alcohol-related acute myopathy, and kidney damage.
