Heavy Drinking on the Digestive Excretory System

Skip To Section

Understanding the effects alcohol has on your body, and the impact of heavy drinking on the digestive system, can help you make informed decisions about your drinking habits and potentially prevent serious health complications. Knowing the risks of problematic drinking patterns can also help you know when it’s time to get help and seek treatment for alcohol use disorder.

Functions of the Excretory System

The digestive excretory system keeps the body stable by helping to eliminate waste, namely from things you eat and drink. The digestive excretory system then helps to excrete liquids from the body that it isn’t going to use (unnecessary material) through urine.

The excretory system is made up of four main components.

  • Two kidneys: These organs filter your blood, regulate blood pressure, make red blood cells, balance the chemical and mineral makeup of your body, and remove excess fluid and waste through urine.
  • Two ureters: These tubes are connected to the kidneys. They move urine away from the kidneys to the bladder.
  • Bladder: This organ collects and stores urine.
  • Urethra: This tube is connected to the bladder. It moves urine out of the body.

The Effects of Alcohol on the Excretory System

Alcohol and kidneys are closely linked because alcohol makes kidneys less effective at filtering waste and keeping the body’s fluid balance. Heavy drinking increases the chance of kidney disease and can make existing conditions worse. This shows how important it is to know how alcohol affects kidney health.

When you drink alcohol, you feel the need to urinate more often. Alcohol is also a known diuretic, so it can give you diarrhea. These effects are short-term. For this reason, light to moderate drinking is less likely to have a significant lasting impact on your digestive excretory system. Heavy drinking is the problem. 

In 2017, more than a quarter of Americans (ages 18 and older) drank heavily in the prior month, according to a national survey. Regular heavy drinking can make it difficult for your excretory system to work properly. A buildup of alcohol and its metabolites in your system can cause a wide range of problems that can be deadly if left untreated. 

The Impact of Alcohol and Kidneys

When excessive amounts of alcohol are consumed regularly, it can cause serious damage to the excretory system. The kidneys play a crucial role in filtering out waste products from the blood and regulating fluid levels in the body. When alcohol is present in the bloodstream, it can impair the kidneys’ ability to function properly. This can lead to a build-up of toxins and waste products in the body, which can lead to various health issues including:

  • Difficulties with kidney filtration
  • Kidney scarring 
  • Kidney damage
  • Alcoholic nephropathy
  • Kidney failure

Chronic alcohol abuse can also increase the risk of developing kidney stones, as alcohol consumption dehydrates the body and increases the concentration of minerals in urine. These kidney stones can cause severe pain and discomfort and may require medical intervention to be removed.

In addition to directly affecting the kidneys, excessive alcohol consumption can also lead to high blood pressure. This puts extra strain on the kidneys, making them work harder than they should. Over time, this can weaken the organ and increase the risk of developing chronic kidney disease.

Heavy drinking has been linked to an increased risk of liver disease. The liver works closely with the kidneys to eliminate toxins from the body. When both organs are compromised by excessive alcohol intake, it can lead to serious health consequences.

The Effects of Alcohol on the Digestive System

Alcohol is primarily filtered through the liver. Unlike other things that you eat and drink, it is directly absorbed into the bloodstream. This means that the kidneys will have to work overtime to try and pull the toxic metabolites that alcohol creates out of the system.

When you drink a lot of alcohol, two main things can happen. It can either cause a backlog in your system, leading to infection or sepsis, or it can cause your body to remove the liquids too fast, causing malnourishment and dehydration.

Short-Term Effects of Alcohol on Digestion

Alcohol enters your bloodstream quickly and can start impacting your mind and body within 10 minutes of taking a drink. Your liver can only metabolize a little alcohol at a time, and the rest remains in your bloodstream for the time being.

Short-term effects of alcohol on your excretory system include:

In the case of excessive alcohol consumption and alcohol poisoning, Mayo Clinic warns that severe dehydration, seizures, hypothermia, irregular breathing and heart rate, brain damage, choking, and loss of consciousness can occur. An alcohol overdose can be fatal, often due to stroke or heart attack.

Long-Term Damage

Most people who drink do so in moderation. Heavy or excessive drinking can cause a lot of issues socially, personally, emotionally, and physically. Heavy drinking is defined by the Centers for Disease Control and Prevention (CDC) as 15 or more drinks a week for a man and 8 or more drinks in a week for a woman.

Binge drinking is a type of excessive drinking that raises your BAC (blood alcohol content) to above the legal limit of 0.08%. Usually, this means five drinks for a man (four drinks for a woman) in a two-hour time period. Regularly binge drinking can wreak havoc on your brain and body.

Alcohol can build up in the body, which can lead to infection or sepsis. When your kidneys can’t filter out alcohol through urine quickly enough, it can back up, causing inflammation and infection. An untreated infection can then lead to sepsis, which can be life-threatening.

As a diuretic, alcohol can also lead to dehydration and an imbalance of important minerals, nutrients, and electrolytes. This can cause unhealthy weight loss and malnutrition.

Other potential long-term effects of heavy drinking on your digestive excretory system can include:

  • Kidney stones.
  • Urinary tract infections.
  • Inflammation of the lining of the bladder and GI tract in general.
  • Kidney damage and possible failure.
  • Irregular blood pressure.
  • Lowered immune system function.

Reversing the Damage

The CDC warns that binge drinking can cause acute kidney failure, but the damage can often be reversed if you stop drinking and allow your kidneys time to heal. Depending on how long and how much you drank, this recovery timeline can vary.

Some of the damage can be irreversible, however. Regular heavy drinking doubles your risk for chronic kidney disease. This risk quadruples if you also smoke.

Alcohol can raise your blood pressure, and regular heavy drinking can cause chronic high blood pressure. This is another risk factor for kidney disease.

Kidney disease can lead to kidney failure. You may then need to endure regular kidney dialysis to filter your blood and keep things properly balanced, or undergo a kidney transplant. Heavy drinking can make it hard for you to qualify for a kidney transplant.

Effects of Alcohol Abuse

When Do You Need Treatment for Alcohol

Alcohol is a social beverage, and it’s seemingly everywhere in society. Again, it’s generally safe to drink in moderation.

Regular heavy drinking can lead to an alcohol use disorder (AUD), however. This is a treatable brain disease. About 16 million people in the United States struggle with an AUD, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) publishes.

You may need treatment for alcohol abuse if you:

  • Regularly drink more than you intended.
  • Are unable to stop drinking once you start.
  • Have cravings for alcohol.
  • Have tried several times to stop drinking, or cut back, and been unable to do so.
  • Spend a lot of time drinking, thinking or talking about drinking, deciding how and when you are going to get your next drink, and recovering from alcohol’s effects.
  • Find alcohol gets in the way of your job, family obligations, or schoolwork.
  • Give up social or other activities that were important to you before in order to drink instead.
  • Keep drinking even though you know it is going to have negative emotional, health, and/or social problems.
  • Find the amount of alcohol you used to drink doesn’t impact you the same way, and you need to drink more to feel its effects.
  • Experience withdrawal symptoms when alcohol wears off. These may include restlessness, anxiety, depression, insomnia, shakiness, fatigue, irritability, sweating, and appetite changes.
  • Keep drinking even though it is causing problems in your life.
  • Get into situations that are physically risky because of drinking. Examples include driving while drunk, having unsafe sex, or getting into situations that could cause accident or injury.

Reducing the amount of alcohol you drink can positively impact your body and brain, and allow your excretory system a chance to health. Get help to stop heavy drinking and give your digestive system the best chances of a full recovery.
