Alcohols Impact on Kidney Function PMC

Similar alterations have been found in body fluid volumes among chronic alcoholic patients. In summary, there is no exact evidence that alcohol consumption aggravates the state of CKD or increases all-cause mortality in CKD, and the protective effect of abstinence on such patients is unclear. Although there has long been controversy about the renal-protective effect of alcohol consumption on kidney injury, the renal-protective effects of polyphenols and other bioactivators from wine has been demonstrated in many studies [15,95,97,101–103]. 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]. They have been demonstrated to have ROS scavenging, antiplatelet, anticancer, anti-inflammatory, antidiabetic, antibacterial, antiaging, and cardiovascular and renal-protective effects [105–112]. Moreover, other bioactivators in red wine, excluding resveratrol, and those in white wine, also have the function of ROS scavenging and renal protection [7,84,113].

  • In other words, the kidneys’ ability to excrete excess fluid by way of dilute urine is impaired, and too much fluid is reabsorbed.
  • The risk for alcohol-related diseases is also higher in women than in men.
  • In an acute sense, consumption of alcohol can lead to uninhibited behavior, sedation, lapses in judgment, and impairments in motor function.
  • And other disorders, such as ADHD (attention-deficit/hyperactivity disorder) and Williams syndrome, have some symptoms like FAS.
  • Interestingly, studies find that CYP2E1 induction is much more robust in the kidneys compared with the liver (Roberts et al. 1994; Zerilli et al. 1995).

Although resilient, the kidneys can deteriorate as a result of malnutrition, alcohol abuse or dependence, or liver and other diseases. Healthy kidneys are vital to the function of all the body’s organs and systems. The kidney tubules play an important role in keeping the body’s water and electrolyte levels in equilibrium. 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).

Drinking Alcohol Affects Your Kidneys

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. 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. Laube and colleagues (1967) suggested that both cellular enlargement and cell proliferation contribute to such nephromegaly.

The Known Brain-Damaging Effects of Excess Alcohol

As early as thousands of years ago, humans had mastered the primitive aspects of brewing technology. Nowadays, many forms of ethyl alcohol are available, such as beer, wine, vodka, and other spirits, and these have become very popular among adults. The World Health Organization estimates that more than 55% of adults consume alcohol, and 140 million people worldwide have alcoholism [1,2]. In fact, alcoholism is a serious problem in Asia, where 10.6–23.67% of men and 1.84–5.3% of women have a history of excessive alcohol consumption [3–9]. Drinking alcohol to excess is linked to several health problems, including liver disease and an increased risk of some cancers (not to mention risks from drunk driving or accidental injuries while intoxicated). Even if you’re not a lifeguard on duty under the blazing summer sun, staying hydrated is essential for virtually every function of the body.

Renal Patients and Alcohol

Water content for fruits and vegetables varies dramatically, but watermelon, cantaloupe, strawberries, spinach, cabbage, celery, lettuce, and squash are all at least 90% water. One scientific analysis published in 2019 found that only 25-30% of U.S. adults are well hydrated. The best way to tell if you’re among how does alcohol affect the kidneys them is to check out a urine color chart (a tool backed by research, by the way). Still, experts warn that vitamins present in your urine and the lighting in your bathroom can impact the sensitivity of these color charts. As anyone who’s consumed alcohol knows, ethanol can directly influence brain function.

Controlled clinical trials have not shown that diet alone can significantly change the blood pH of healthy people. Moreover, a direct connection of blood pH in the low-normal range and chronic disease in humans has not been established. A healthy body is designed to send thirst signals when the body becomes depleted of fluids. Thirst is the desire to drink, and is not only driven by physiological cues but behavioral cues.

Alcohol consumption and risks of more than 200 diseases in Chinese men

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 are overly dilute, the kidneys dilute the urine, allowing more water to leave the body. “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. Therefore, we need more evidence to determine whether abstinence can relieve and heal the kidney damage caused by long-term alcohol consumption and the effects of alcohol abstinence on the prognosis of patients with CKD. The glomeruli are sensitive to fluctuations of systemic blood pressure (BP), and the RAS is the most important BP control system in the kidneys.

  • Although the mechanisms responsible for these effects have not been established, an experimental study by Chan and Sutter (1983) offers some insight.
  • Alcohol can cause problems for a developing baby throughout pregnancy, including before a woman knows she’s pregnant.
  • Another study with dogs (Beard et al. 1965) disclosed that the effects of chronic alcohol consumption endured even longer.
  • Heavy drinking makes it more difficult for you to qualify for a kidney transplant.
  • And in rare cases, binge drinking — five or more drinks at a time — can cause a sudden drop in kidney function called acute kidney injury.
  • Age, diabetes, hypertension, hyperlipidemia, and smoking are traditional risk factors of cardiovascular disease in patients with CKD [15–17].

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).
