How Alcohol Affects Your Body

You may think that a glass or two of alcohol a day can’t affect you. However having it everyday or every week can affect you, it can take a toll on your body by having it all the time. If you are drinking one glass a day it may become more difficult to stop after one, the cumulative effects can add up.

Circulatory System

Alcohol can affect your heart and lungs. People who drink on a regular basis and drink lots are more prone to developing heart-related issues than people who do not drink. The problems can include: irregular heartbeat, high blood pressure, stroke, heart attack, heart disease, heart failure.

Immune System

Drinking heavily can reduce your body’s ability to fight off invading germs and viruses. Drinking over a long period of time can increase the chances of developing pneumonia or tuberculosis. It can also increase your risk for several types of cancer including mouth, colon, breast, and liver.

Digestive System

Mostly the connection between alcohol and the digestive system is unclear, the symptoms tend to appear after the damage have been done. The more you drink, the greater the damage will be. Drinking can damage the tissues in your digestive tract and prevent your intestines from digesting food and absorbing nutrients. It can also lead to: gassiness, bloating, a feeling of fullness, diarrhoea.


Some people who drink regularly, may develop a physical and emotional dependency on alcohol. Alcohol withdrawal can be difficult and life-threatening. Symptoms of withdrawal can include: nausea, anxiety, depression, nervousness, tremors, heavy sweating, high blood pressure, irregular heartbeat. If you or someone you know is dealing with withdrawal symptoms then ask for some professional help, medical help can most of the time be the best way to break the physical addiction.

Central Nervous System

Slurred speech is one of the main signs that you have had too much to drink, alcohol reduces the communication between your brain and your body. This makes coordination difficult; you may find it hard to balance. It also makes it difficult for your brain to make long-term memories making it difficult to think clearly and make rational choices. Over a long period of time, frontal lobe damage can occur. This part of the brain is responsible for short-term memory, judgement, emotional control, and other vital roles. Chronic and severe alcohol abuse can also cause permanent brain damage.

All these effects are dangerous and possibly life-threatening, the best way is to stop consuming lots of alcohol. Drinkline is the national alcohol helpline, if you’re worried about your own or someone else’s drinking then you can contact them on 0300 123 1110.
