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. Heavy drinking can also cause liver disease, which also makes your kidneys work harder.
What drinks are hardest on kidneys?
Alcohol can impact many different parts of the body, but most commonly it damages the liver and can lead to a condition called cirrhosis. The ADH gene family encodes enzymes that metabolize various substances, including ethanol. The activity of these enzymes varies across different is alcohol processed by the kidneys organs (see Table 1).
- According to a 2017 review, the question of whether alcohol consumption affects kidney function remains controversial.
- Besides ethanol, CYP2E1 can oxidize many other compounds including acetone, benzene, and other alcohols.
- Long-term alcohol use can change your brain’s wiring in much more significant ways.
- The age-standardized prevalence rates (ASPRs) per 100,000 people were 1547 cases of AUD, 313 cases of ALD, and 10 cases of primary liver cancer due to alcohol.

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. If you don’t have enough ADH or ALDH, your stomach will send the alcohol directly to the small intestine. From there, it hits your bloodstream and your brain, and you start feeling its effects.
Alcohol Misuse and Kidney Injury: Epidemiological Evidence and Potential Mechanisms
Although most of the alcohol is metabolized in the liver, the kidneys are equally important in the metabolism and excretion of ethyl alcohol. Some enzymes that are necessary for ethanol metabolism, such as alcohol dehydrogenase, CYP2E1, and CYP24A1, have been found in the kidneys 22,23. Furthermore, approximately 10% of ingested ethanol is excreted by the kidneys in its original form 21. Therefore, excessive alcohol consumption places a major strain on the normal metabolic processes of the kidneys. Alcohol exacerbates insulin resistance, mitochondrial dysfunction, and oxidative stress, disrupting lipid metabolism and promoting inflammation.
The major enzyme system(s) responsible for the oxidation of ethanol, alcohol dehydrogenase, and to a lesser extent, the cytochrome P450-dependent ethanol-oxidizing system, are present to the largest extent in the liver. Liver damage lowers the rate of alcohol oxidation and hence, elimination from the body. Ethanol is a nutrient and has caloric value (about 7 kcal per gram; carbohydrates and protein produce 4 kcal per gram, while fat produces 9 kcal).
- The concentration of ethanol in a tissue is dependent on the relative water content of the tissue, and reaches equilibrium quickly with the concentration of ethanol in the plasma.
- Calabrese and Rizza (1999) found that ethanol induced a significant increase in the levels of fatty acid ethyl esters.
- In addition, ROS can interact with lipids, proteins, and DNA in a process called peroxidation, which can have harmful consequences.
- Alcohol metabolism begins with absorption in the stomach and small intestine, followed by enzymatic processing in the liver through oxidative and non-oxidative pathways.
Studies suggest that several mechanisms produce ROS in alcohol-damaged organs, including the liver (Cederbaum et al. 2009), heart (Tan et al. 2012; Varga et al. 2015), and kidney (Latchoumycandane et al. 2015). CYP2E1 is of particular interest when thinking about potential mechanisms for alcohol-related kidney damage. The body mainly metabolizes alcohol using the enzyme alcohol dehydrogenase, which is expressed primarily in the liver.
For instance, you should abstain if you are pregnant or under the age of 21. If you are being treated for a kidney-specific condition, please talk to your doctor about your alcohol intake. The NKF adds that most people in the United States who have both liver disease and kidney dysfunction are alcohol dependent. According to a 2022 review, symptoms do not usually manifest until stage 4 or 5 of the disease. According to a 2017 review, the question of whether alcohol consumption affects kidney function remains controversial.
