Learning about the effects of alcohol on the body is a crucial step towards making informed choices. Despite the widespread use of alcohol globally, many people remain unaware of its short- and long-term effects on the body.
At The Wellbourne Clinic, our aim is to help individuals understand the full picture of alcohol use, from its impact on mental health to the risks of long-term alcohol consumption. This guide offers comprehensive insight into what alcohol really does to your body.

Why understanding the effects of alcohol is important
Recognising the physical and mental risks of alcohol consumption can empower people to change harmful habits, seek support, or moderate their intake. From minor discomfort to serious illness, alcohol affects nearly every system in the body.
Short-Term Effects of Alcohol on the Body
Impact on Coordination and Judgment
Even after a small amount of alcohol, brain function is slowed, decision-making is impaired and motor skills are reduced. This increases the risk of accidents and harmful behaviour.
Hangovers and Dehydration
Even moderate drinking can cause hangovers, including headaches, nausea and fatigue. This is due to the dehydrating effects of alcohol and the way it disrupts sleep and blood sugar levels.
Long-Term Effects of Alcohol on the Body
Liver
The liver is responsible for filtering toxins from the blood. It has the ability to break down alcohol, but over time heavy alcohol consumption can lead to:
-
- hepatitis
- steatosis (fatty liver disease)
- cirrhosis
Heart and blood
Chronic drinking may raise blood pressure, increase the risk of heart disease and stroke, and weaken the heart muscle. This especially affects individuals with pre-existing conditions.
Cancer risk and immune system
Alcohol is linked to cancers of the mouth, throat, liver and breast. Excessive alcohol consumption also reduces the number and function of white blood cells, which weakens the immune system’s ability to fight illnesses.
Effects of Alcohol on Mental Health
As well as exploring the effects of alcohol on the body, it is important to mention the effects it can have on mental health.
Heavy alcohol use is strongly associated with both anxiety and depression, often making existing mental health conditions worse. While some may experience a temporary sense of relaxation, regular drinking can disrupt the brain’s chemical balance and potentially lead to a cycle of dependence.
Alcohol also has the ability to decrease memory and concentration, and lead to long-term cognitive decline, especially in older adults.
How much alcohol is too much?
According to the NHS, the recommended “low-risk” alcohol limit in the UK is 14 units per week. They advise to spread this across multiple days, and incorporate alcohol-free days throughout the week. You can calculate alcohol units here.
When to seek help
If you are consuming more than the recommended units per week, finding it hard to cut back or noticing the effects of alcohol on your body, it may be time to seek support.
