Alcohol can have a detrimental effect on kidney health. While drinking one or two alcoholic drinks now and then usually has no serious effects, excessive drinking can wreak havoc on these vital organs. When you drink heavily, your kidneys have to work harder to filter out the alcohol, and this extra stress can continue to increase over time and cause the kidneys to deteriorate. Binge drinking can cause a sudden drop in kidney function called acute kidney injury, which can lead to chronic kidney disease. Regular heavy drinking can also be harmful to your kidneys and can double the risk of chronic kidney disease. Alcohol can also cause high blood pressure, which is a common cause of kidney disease.

Oxidative stress | Excessive alcohol consumption can lead to oxidative stress in the kidneys, damaging their delicate filtering system. |
Inflammation | Alcohol can cause inflammation in the kidneys. |
Dehydration
Drinking alcohol can lead to dehydration, which puts extra strain on the kidneys. Alcohol has a diuretic effect, which means it increases urine production and can leave the body dehydrated. This dehydration can affect the normal function of cells and organs, including the kidneys.
The kidneys play a crucial role in regulating the body's fluid levels and maintaining a balance of water and electrolytes. When the body is dehydrated, the kidneys may not be able to perform these functions optimally. This can lead to disturbances in electrolyte concentrations and even clinical evidence of dehydration.
In addition, dehydration caused by alcohol consumption can affect the kidneys' ability to regulate the body's acid-base balance. Alcohol can interfere with the kidneys' ability to regulate acidity, which is important for maintaining the body's metabolic balance.
To prevent dehydration and reduce the risk of kidney-related problems, it is important to limit alcohol intake and stay well-hydrated. Maintaining a healthy fluid balance is crucial for kidney health and overall well-being.

High blood pressure
Drinking alcohol, especially in large quantities, can have a detrimental effect on kidney function. This is due to the additional stress placed on the kidneys as they work to filter out the alcohol from the blood.
Drinking alcohol can increase your risk of high blood pressure. This is because alcohol causes changes in the function of the kidneys, making them less able to filter the blood. The kidneys are responsible for maintaining a healthy balance of water and electrolytes in the body. Alcohol has a dehydrating effect on the body, and this can impact the kidneys' ability to maintain the right amount of water. This dehydration can affect the normal function of cells and organs, including the kidneys.
When the body is dehydrated, the kidneys respond by retaining more water, which can lead to an increase in blood volume and blood pressure. Additionally, alcohol can disrupt the hormones that control kidney function, including those that regulate blood pressure. Alcohol consumption can also lead to liver disease, which can further impair kidney function and contribute to high blood pressure.
According to the National Kidney Foundation, consuming more than two alcoholic drinks per day increases your risk of high blood pressure. High blood pressure is a common cause of chronic kidney disease. Therefore, it is important to limit alcohol intake to protect kidney health. Heavy drinking is defined as more than three drinks per day (or seven per week) for women and more than four drinks per day (or 14 per week) for men.
If you are concerned about your alcohol consumption or its impact on your health, it is important to seek advice from a healthcare professional.

Liver disease
While alcohol does not directly harm the kidneys, chronic drinking can lead to liver disease, which in turn can cause kidney dysfunction. Liver disease impairs the kidneys' ability to filter blood and maintain the right amount of water in the body.
The liver is often paired with the kidneys, and liver disease can therefore have a knock-on effect on kidney function. Alcoholic liver disease can lead to kidney damage and kidney disease, as the changes in the body caused by liver disease can be so severe that the kidneys stop functioning or fail completely.
Liver cirrhosis, for example, can cause the kidneys to retain sodium, resulting in a progressive accumulation of extracellular fluid. This excess fluid is often sequestered in the abdominal region, manifesting as swelling or marked ascites. As long as cirrhotic patients are unable to excrete sodium, they will continue to retain the sodium consumed in their diet, leading to increasing ascites and weight gain.
Another complication of liver disease is hepatorenal syndrome, which can lead to a marked decrease in urine flow, almost no sodium excretion, hyponatremia, and ascites. While hepatorenal syndrome often occurs after an event that reduces blood volume, such as gastrointestinal bleeding, it can also develop without any apparent cause. It is a grave prognosis for patients with alcoholic cirrhosis.
Chronic alcohol consumption can also lead to alcoholic ketoacidosis, a potentially serious condition characterised by an abnormal accumulation of ketone bodies. This is a result of excessive alcohol consumption over several days, where the individual consumes alcoholic beverages and nothing else.
In summary, while alcohol does not directly harm the kidneys, chronic drinking and alcohol abuse can lead to liver disease and associated kidney dysfunction. This is due to the close relationship between the liver and kidneys in maintaining the body's fluid balance and filtering blood.

Hormone disruption
The kidneys are responsible for producing hormones that influence a range of physiological processes, including blood pressure regulation, red blood cell production, and calcium metabolism. Alcohol consumption can disrupt the hormonal control mechanisms that govern kidney function.
One of the key ways in which alcohol achieves this is by inhibiting the release of the antidiuretic hormone (ADH), also known as vasopressin. Normally, ADH promotes the formation of concentrated urine by inducing the kidneys to conserve fluids. In the absence of ADH, the kidneys become impermeable to water, preventing its reabsorption into the body. As a result, the urine formed is dilute, and the concentration of electrolytes in the blood rises.
Additionally, alcohol consumption can lead to a state of low blood sugar (hypoglycaemia) and activate the sympathetic nervous system, which coordinates the body's response to stress. Both of these factors can further impact hormones that regulate kidney function.
The disruption of hormonal control mechanisms by alcohol consumption can have a range of negative consequences on kidney function and overall health.

Kidney pain
Drinking alcohol can have harmful effects on your kidneys, and some people may experience kidney pain after drinking. However, according to kidney specialist Shane A. Bobart, MD, FASN, there is currently no research to suggest a direct link between alcohol consumption and kidney pain. While alcohol is not proven to be the cause of kidney pain, it does act as a diuretic and can lead to dehydration, which can put extra strain on your kidneys.
If you experience kidney pain after drinking, applying a heat pad to your back and sides can help relieve the pain. It is also important to stay hydrated and avoid drinking more alcohol, coffee, or other stimulants. Taking a warm bath with Epsom salt is another excellent remedy for easing pain. If the pain around your kidneys persists or becomes severe, it is crucial to contact a healthcare professional as it could indicate a more serious issue.
To maintain kidney health, it is recommended to limit alcohol intake, stay well-hydrated, and adopt a healthy diet and lifestyle. Excessive alcohol consumption can lead to dehydration, high blood pressure, and liver disease, all of which can negatively impact kidney function and increase the risk of kidney problems. Binge drinking, defined as consuming four to five drinks within two hours, can cause a sudden drop in kidney function known as acute kidney injury. This condition may require dialysis and can sometimes lead to lasting kidney damage.
In summary, while kidney pain may not be directly linked to alcohol consumption, drinking excessively can have detrimental effects on kidney health. It is important to monitor your alcohol intake and seek medical advice if you experience persistent or severe kidney pain.
