Alcohols Impact on Kidney Function PMC
However, other studies found that long-term alcohol consumption aggravates renal fibrosis, which may be related to epithelial mesenchymal transdifferentiation and fibrosis induced by ethanol [33,47,56]. Having more than three drinks in a day (or more than seven per week) for women, and more than four drinks in a day (or more than 14 per week) for men, is considered “heavy” drinking. Heavy drinking on a regular basis has been found to double the risk for kidney disease. You probably know someone who developed health problems from drinking too much alcohol. Alcohol can impact many different parts of the body, but most commonly it damages the liver and can lead to a condition called cirrhosis. This often comes up when I am evaluating someone for kidney disease.
What Stages Aren’t Reversible?
- Samadi et al. also suggested that ethanol induces depression of nephrin and podocin in podocytes, which contributes to renal injury and proteinuria and is mediated by oxidative stress [44].
- Healthcare providers can measure this with a type of ultrasound called a FibroScan and a panel of blood tests called liver function tests (LFTs).
- In fact, about a quarter of drinkers reported they had done this on at least one day in the past year.
- Moreover, many patients were excluded from the long-term observational studies because they did not attend routine annual health checkups.
- Having hepatitis C or other liver diseases with heavy alcohol use can rapidly increase the development of cirrhosis.
About 90% of heavy drinkers will develop alcoholic fatty liver disease. (For an in-depth discussion of alcohol and the digestive tract, see the article by Keshavarzian in this issue.) The direct role of alcohol-related endotoxin release in alcoholic kidney injury has not yet been studied. However, it is possible that activation of the innate immune system due to endotoxins released by a leaky does alcohol affect your kidneys gut plays a central role in the development of renal damage, as it does for liver damage (Zhang et al. 2008). Although light-to-moderate alcohol consumption may not pose a risk to patients with CKD, the patients’ condition needs to be considered. Many patients with CKD often have other comorbidities, such as diabetes, coronary heart disease, stroke, and other serious chronic diseases.

But the two bean-shaped, fist-sized kidneys sitting at the base of the rib cage are fascinating, multitasking organs. They are at work all day long removing waste, stimulating red blood cell production and keeping the body’s balance of salts, acids and bases in check. If alcohol use leads to cirrhosis, the only way to prevent progression (and reduce the risk of liver cancer or failure) is to quit. Early-stage liver disease is fully reversible once alcohol is stopped. However, if there is progression from fibrosis to cirrhosis, the odds of regression (reversibility) are decreased.
Drinking patterns and associated effects
There are many options for treatment for alcohol use disorders, but there is no one-size-fits-all approach. Eating a healthy diet, getting regular exercise, and avoiding liver-damaging foods such as fried foods, can also help the liver heal during treatment. While the early stages may have no symptoms, later stages can cause symptoms such as fatigue, swelling in the hands and legs, jaundice, loss of appetite, and weakness. Many people with ALD are malnourished (lacking proper nutrition) due to a variety of factors, such as lack of eating, vomiting, and malabsorption (difficulty absorbing nutrients from food). In general, the more severe the ALD, the more malnourished someone becomes. The morning after a night of over-imbibing can cause some temporary effects on your brain.
Influence of alcoholism on the prognosis of patients with CKD
Risks of Alcohol Abuse with Kidney Disease
- One way in which alcohol directly affects the kidneys is by altering the form and structure of this pair of organs, as demonstrated by various animal studies.
- NO is a free gaseous signal molecule produced by the NOS family, including neuronal NO synthase (nNOS), inducible NO synthase (iNOS), and endothelial NO synthase (eNOS), and it plays an important role in hemodynamics regulation.
- 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.

Progressive Symptoms
- However, clinical research shows the amounts and patterns of alcohol consumption both affect eGFR in patients with CKD [7].
- When alcohol enters the bloodstream, it is metabolized (broken down) by the liver into a toxic chemical called acetaldehyde, which is further metabolized to acetate.
- Generally, symptoms of alcoholic liver disease include abdominal pain and tenderness, dry mouth and increased thirst, fatigue, jaundice (which is yellowing of the skin), loss of appetite, and nausea.
- For instance, a 2014 paper that reviewed several studies found no conclusive evidence of either harmful or beneficial effects of moderate alcohol consumption on kidney function.
