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. Some studies found that ethanol has an influence on renal damage, such as apoptosis and epithelial mesenchymal transdifferentiation. Nesreen and Sayed discovered that alcohol consumption significantly increased renal caspase3, caspase8, and caspase9 activity, and ethanol toxicity can increase the ratios of Bax and Bcl-2 in kidney tissues compared to a control group 24,25. This indicates that long-term ethyl alcohol consumption can activate both intrinsic and extrinsic pathways of apoptosis in the kidneys (Figure 1). 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. Overall and subgroup analyses of the association between baseline alcohol consumption and decline in kidney function over 12 years in fully adjusted linear regression model.

Chronic kidney disease (CKD) stages

Kidney dietitian Nick McAleer from Royal Devon and Exeter NHS Foundation Trust offers advice about choosing drinks. Healthy kidneys ensure that such proteins stay out of a normal urine flow; kidneys suffering from chronic alcohol abuse, https://ecosoberhouse.com/article/why-do-alcoholics-crave-sugar-in-recovery/ on the other hand, cannot stop proteins (like albumin) from “leaking” into urine. The National Kidney Foundation warns that albuminuria can be an early sign of kidney disease, which will require nephrology treatment. Jen is a registered dietitian and board-certified in renal nutrition.

• This finding suggests that rhabdomyolysis and myoglobin toxicity may trigger oxidative stress in the kidney via mitochondrial injury.
• Many studies have shown that alcohol consumption is related to cardiovascular disease, urinary protein, and CKD 3,6,16,45,66–69.
• Genetic and individual differences sometimes need to be taken into account 78.
• In general, ethanol causes oxidative stress-related damage in the kidneys, but sometimes, in some conditions, it also improves the antioxidant capacity of the renal cells.

She has over 8 years working with chronic kidney disease, dialysis, alcohol and kidneys and kidney transplant patients. Jen now focuses on sharing kidney-friendly information here at Plant-Powered Kidneys. Like the liver, excessive alcohol consumption can damage the pancreas.

3. Alcohol Consumption

In addition to filtering blood, your kidneys do many other important jobs. One of these jobs is keeping the right amount of water in your body. When your liver isn’t functioning well, it can impair blood flow to your kidneys. “Liver disease can have significant impacts on the kidneys,” says Dr. Bobart.

Alcohol and Chronic Kidney Disease

With the passage of time and positive changes, the kidneys can return to normal, optimal functioning. The human body has dozens of vital organs, and the kidneys are among the most important. They regulate water intake and outtake, they balance the amount of minerals in the body, and they produce vital hormones, according to the Kidney Foundation of Canada. Threats to the normal functioning of the kidneys are serious medical problems, and alcoholism is a contributing factor to kidney disease.

• This type of sudden-onset kidney damage often resolves with time, but it can be lasting in some cases.
• However, another rat model showed that ethanol may increase blood pressure and angiotensin II type 1 receptor expression, causing glomerular morphology changes.
• According to the United Kingdom’s National Health Service (NHS), a person should consult a doctor if they experience symptoms consistent with kidney disease.
• Alcohol consumption, including vodka and red wine, also reduced serum insulin concentrations and enhanced the insulin sensitivity index 24,25.

Although different studies have shown opposite results for the effects of NO and NOS activity with alcohol consumption 19,39,46,47, they came to a similar conclusion that NO and NOS play important roles in glomerular endothelial cell injury. The data set did not contain laboratory data and the CKD diagnosis was dependent on the ICD-9-CM code. Participants’ baseline characteristics, including weight, height, education, marriage status, household income, smoking, drinking, diet, and exercise habits, were self-reported, and recall bias should be concerned. 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.
