Alcohol and your body

English | Cymraeg

Drinking alcohol can affect your body in all sorts of different ways; explore some of the most common effects on our body map.

Brain

The immediate effects of drinking on your brain can include slurred speech, slow reactions, impaired memory and blackouts. Over the longer-term, heavy drinking can cause a number of different types of brain damage.

Overuse of alcohol can worsen the symptoms of many mental health problems. In particular, it can lead to low mood and anxiety.

However, this risk starts to rise when consuming above 14 units per week. Heavy drinking is also associated with both hypertension and increased risk of stroke.

Breasts

Drinking too much can cause gastritis (inflammation of the stomach lining) and stomach ulcers. It can also lead to uncomfortable reflux – digestive contents being forced up into your oesophagus (food pipe).

Heavy drinking can also increase your risk of stomach and bowel cancer.

Liver

Most alcohol that goes into your body is processed by your liver, and if it has to break down too much alcohol the health of your liver will suffer.

Long-term, drinking too much alcohol can lead to fatty liver, hepatitis (inflammation of the liver) and cirrhosis (scarring of the liver) and also liver cancer.
