Kidney disease and alcohol consumption: Causes of kidney pain after drinking alcohol

kidney disease and alcohol consumptionIt is often advised to avoid alcohol consumption if you have kidney disease as it can result in kidney pain, among other complications. Furthermore, consuming over four alcoholic beverages can worsen kidney disease.

The CDC estimates at least two out of three Americans consume alcohol, and some drinkers consume over five drinks at a time. Twenty-five percent of drinkers have admitted they have consumed over five beverages in one occasion at least once in the past year. This is known as binge drinking and it is associated with severe kidney problems.


Even drinking regularly too much too often can damage the kidneys. Regular heavy drinking is associated with double the risk of kidney disease. The risk is even greater among those who drink and smoke.

When we consume alcohol, our kidneys work harder to filter this harmful substance. Too much alcohol causes the kidneys to overwork, contributing to damage. Alcohol also negatively affects the regulation of fluid and electrolytes, thus leading to dehydration in the cells. Furthermore, alcohol can disrupt the balance of hormones that affect the kidneys.

Alcohol can also negatively affect other bodily functions and processes that play a role in the health of the kidneys – for example, blood pressure.

Causes of kidney pain after drinking alcohol

Kidney pain after drinking alcohol may be immediate, or it can be a dull pain even if the drinking has stopped. Here are some common causes for pain of the kidneys after drinking alcohol.

  • Your kidneys are overworking to filter out the alcohol
  • You have a fragile renal pelvis and the excess amount of urine production leads to pain
  • You have a pelviureteric junction (PUJ) obstruction
  • You have kidney stones
  • You have liver disease

Kidney pain can vary depending on the underlying cause. It may feel sharp, sudden, or excruciating, it may worsen at night, it may feel like a severe pain between the buttocks and lower ribs. The pain may radiate down, and it may be accompanied by fever, nausea, blood in urine, vomiting, and painful urination.

Safe levels of drinking alcohol for better kidney health

The recommended serving for alcohol is usually one drink, but the size of the drink can vary depending on the beverage. For example, one drink can be classified as 12 ounces of beer, five ounces of wine, or 1.5 ounces of hard liquor.

Having more than three drinks a day, or seven in a week, is problematic for your kidneys. Binge drinking refers to having more than five drinks in a two-hour period.

Pregnant women, seniors, persons taking certain medications, persons with smaller body build, or persons with certain medical conditions should avoid drinking alcohol as much as possible.
