Impact of alcohol on the liver

After ingestion, alcohol is metabolised in the liver. As a result, chronic alcohol intake can cause hepatitis, cirrhosis, and fatty liver. The liver can tolerate alcohol in small amounts. However, excessive intake can lead to permanent illnesses. The clinical findings in such conditions can range from acute ailment to end-stage cirrhosis. Cirrhosis of the liver results in the secretion of harmful toxins into the bloodstream, negatively affecting the brain. In addition, it creates extra fluid called ascites in the abdomen, which leads to kidney failure. Around 15 to 20% of consumers of alcohol suffer from cirrhosis.

A liver function test is performed to find out the liver condition. The serum level of liver enzymes rises when there is any abnormality in the liver. This enzyme is usually elevated to a higher number in case of cirrhosis. Treatment for cirrhosis includes symptomatic treatment, and abstinence from alcohol is essential. The end-stage of this disease can also require a liver transplant.

  1. Impact of alcohol on the heart

Excessive alcohol intake speeds up the heart rate, which leads to increased blood flow and enlargement of the blood vessels. Cholesterol levels increase in the alcoholic, accumulating in the heart vessels, and as a result, the oxygen supply declines. Cardiac muscles are then stretched to meet the heart's oxygen demand, hence leading to angina and myocardial infarction. Regular use of alcohol results in high blood pressure and thickens the arterial walls, which puts the heart at risk. There is even a risk of stroke and heart failure.

  1. Impact of alcohol on pancreas

Alcohol is the leading cause of pancreatitis. The pancreas swells up and becomes inflamed to the point where the patient presents with severe pain in the abdomen. The acinar cells present in the lumens of the pancreas secret pancreatic juice, which is helpful in the digestion of food. The toxin is produced as a by-product of alcohol, damages these acinar cells and decreases the flow of pancreatic juice, which can eventually affect the metabolism of food.

  1. Impact of alcohol on kidneys

The kidneys play an essential role in regulating water and electrolytes in the body. Therefore, the water and minerals remain balanced when the kidney functions correctly. However, frequent alcohol intake creates harmful toxins which damage the kidney and disturb its functioning, resulting in oedema. Alcohol also affects the hormones of the kidney, which leads to acute infection. Similarly, alcohol can cause kidney stones which are present with severe pain.

  1. Impact of alcohol on the brain

The brain is the control house of the body. It arranges and coordinates the organs of our body with one another. Any harmful effects on the brain can derange this coordination and result in a severe outcome. Alcohol influences our brain by diminishing its function. Examples include memory loss, slow response, impaired speech, and dim vision. In addition, studies found that the brain reduces in size in those who use alcohol.

  1. Impact on the immune system

Alcohol impairs the immune system and brings down the defensive power of our body to fight against the infection. In addition, it causes vitamin and mineral deficiency, which are needed to improve our body's immune system.

  1. Increases the risk of cancer

Alcohol and its by-products generate cancer-causing substances called carcinogens. These carcinogens develop cancer cells in the breast, liver, prostate, oesophagus, and head and neck region. A study suggests that alcohol increases the chance of head and neck cancer at least 3 to 4 times.

  1. Impact on muscle and bones

As discussed earlier in this article, alcohol intake causes a deficiency of vitamins and minerals in the body. These vitamins and minerals are the core substances of bone and muscles. In the case of mineral deficiency, the bone structure becomes less dense and more fragile. Fragile bones are prone to fracture. In addition, alcohol elevates uric acid in the blood, which deposits in the joints and causes severe pain and dryness. The addict feels tired and finds it difficult to complete his daily task due to muscle weakness.

  1. Impact on the digestive system

The liver secretes bile juice for the metabolism of food. Excessive alcohol intake reduces the secretion of bile juice from the liver and, therefore, disturbs the metabolic and absorption process of the body. In addition, it increases bowel movement resulting in diarrhoea. Some cases have also reported rectum carcinoma in alcoholics.

  1. Impact on senses

Alcohol reduces the function of our senses both in the short-term and long-term. Our bodies become unable to perceive an external stimulus of taste, hearing, smell, and touch. It diminishes the nervous system, which cannot respond appropriately to stimuli.


There are many adverse effects relating to alcohol consumption - the more serious effects, being in the long-term. These effects are mostly unseen and may require a doctor's diagnosis, however, you can make a change by monitoring your daily alcohol intake.
