How Alcohol Affects Your Immune System?

Understand the effects that alcohol has on your body’s immune system and the short and long-term consequences that can happen when left unmoderated. 

Alcohol abuse such as heavy drinking has a negative effect on immunity and impairs immunological function. When most people think of drinking alcohol, they usually don’t think about the body’s immune system, but alcohol can decrease the body’s defenses against viruses and bacteria, increasing the risk of colds, bacterial infections, and severe illnesses like cancer and liver failure.

Understanding how alcohol affects the body can help you live a longer, healthier life, therefore it’s crucial to be aware of the damaging effects it can have on the immune system.

How it Affects the Immune System

Alcohol has a variety of physiological effects. Those who frequently drink or who consume a lot of alcohol may develop hangover symptoms such as nausea, headache, and dehydration. Alcohol, however, can also compromise the immune system, resulting in life-threatening illnesses, and increasing a person’s susceptibility to infections and viruses. Alcohol immunosuppression can make someone more susceptible to major illnesses like cancer or septicemia as well as ordinary colds.

Alcohol makes red blood cells harmfully connect to one another and produces inflammation throughout the body. Smaller blood arteries become blocked by abnormal red cell bonding, which reduces the body’s supply of nutrients and oxygen and prevents the immune system from getting the nutrition it needs.

Short-term Effects of Alcohol on the Immune System

You can suffer negative health effects shortly after drinking because upon consumption alcohol begins to impact your body that leaves you vulnerable to the following immediate negative consequences on the immune system:

Greater Susceptibility to Illness

Your body starts prioritizing alcohol digestion as soon as you take a sip. This indicates that the body’s metabolism changes to concentrate on breaking down alcohol while using energy away from other vital processes like disease prevention. Your body’s capacity to fight against viruses and infections is decreased when it is metabolizing alcohol, increasing your risk of getting a cold or another more serious illness.

Additionally, alcohol impairs sleep, which raises the risk of illness and shortens the time it takes to recover.

Digestive Problems

Alcohol causes stomach inflammation and kills beneficial microorganisms in the gut. As alcohol moves through the body, it first enters the gastrointestinal system, where it absorbs into the bloodstream. It modifies the microbiota of the gastrointestinal tract, affecting its integrity and structure.

Microorganisms found in the intestine assist to keep the immune system strong, lower the risk of illness, and support proper digestion. Drinking alcohol destroys these bacteria, making it harder for the body to get rid of diseases. Viral and bacterial illnesses can intensify and turn into more serious problems in the absence of good gut bacteria. Additionally harming T cells, neutrophils, and epithelial cells, alcohol also impairs the function of the intestinal barrier.

Damage to the gut barrier might increase the body’s susceptibility to food poisoning, and epithelium.

Long-term Effects of Alcohol on the Immune System

Heavy drinking can lead to health issues that, if unchecked, can develop into catastrophic illnesses. Additionally, if alcohol consumption is continued while having negative effects on the body, those effects may become worse. The following long-term impacts can result from heavy or frequent alcohol consumption:

Liver problems

Because the liver filters alcohol, alcohol is a common cause of liver damage. A portion of the liver’s cells die after consuming alcohol, and new ones grow in their place. Heavy drinking over time might diminish a liver’s capacity for regeneration and result in alcoholic liver disease (ALD). The typical progression of this alcoholic liver disease is that it begins as fatty liver disease, then advances to alcoholic hepatitis, and finally, to alcoholic liver cirrhosis.

Hepatitis B and C

Liver inflammation is a symptom of hepatitis. Hepatitis is frequently brought on by a virus, but it can also be brought on by some prescription drugs, a few medical disorders, excessive alcohol consumption, and transient infections. Alcohol can impair the immune system, making the body more susceptible to illnesses and viruses like hepatitis B and C.

Hepatitis and alcohol use disorders frequently hasten the evolution of liver disease, and alcohol usage can allow the hepatitis virus to persist as a chronic illness.
