Think a drink is harmless? Here’s what it does to your body

Experts warn that there is no safe level of alcohol, and reducing consumption can significantly improve individual and public health outcomes

Alcohol-consumption - 1

Alcohol is often seen as a symbol of celebration, whether at weddings, parties, or even at corporate events to celebrate success. But behind this socially accepted habit lies a serious and often underestimated public health problem.

In India, alcohol consumption is not rare. Studies suggest that around 15 per cent of Indians consume alcohol, and harmful use is seen in a significant proportion. Increasingly, young people are being targeted by aggressive marketing and social normalisation, leading to rising consumption trends.

Globally, alcohol contributes to a staggering burden of disease. According to the World Health Organization, alcohol is responsible for about 2.6 million deaths every year and is linked to more than 200 diseases and injuries. 

Damage to the body: More than just the liver

Most people associate alcohol with liver damage and rightly so. Alcohol can lead to fatty liver, alcoholic hepatitis and cirrhosis (irreversible liver damage). But the harm goes far beyond the liver.

Brain and Mental Health

Alcohol directly affects the brain. It impairs judgment, memory, and coordination. Over time, it can lead to addiction, depression and anxiety and cognitive decline. In younger individuals, whose brains are still developing, the damage can be even more profound.

Cancer Risk

Alcohol is classified as a Group 1 carcinogen, meaning it is a proven cause of cancer. It increases the risk of oral cancer, throat and esophageal cancer, liver cancer and breast cancer. Importantly, even small amounts of alcohol increase cancer risk. There is no completely safe level. 

Alcohol and society: A wider impact

Alcohol does not just harm the person drinking; it also affects families, communities, and society at large.

Road accidents

Alcohol impairs reaction time and judgment. It is a major contributor to road traffic accidents and fatalities, particularly among young adults.

Violence and Crime

Alcohol is strongly associated with assaults, murders and sexual violence. It lowers inhibitions and increases impulsive behavior, often with devastating consequences.

Domestic violence

In many households, alcohol plays a central role in domestic abuse, leading to physical, emotional, and psychological trauma, especially for women and children.

The financial burden: A hidden crisis

Alcohol is not just a health issue; it is an economic one. A significant portion of income may be spent on alcohol. Health care costs rise due to alcohol-related illness. Alcohol may result in loss of productivity and employment. In fact, studies show that the economic cost of alcohol often exceeds the revenue generated from its sales. 

The myth of 'safe drinking'

Many people believe that 'moderate drinking' is safe, or even beneficial.

Science tells a different story. Alcohol is a toxic substance. It has no essential role in human health. The risk is dose-dependent and increases with every drink. The safest level of alcohol consumption is zero.

Can people quit alcohol? Absolutely. The most important message is that it is possible to quit. Help is available.

Medical support

Doctors can help manage withdrawal symptoms, cravings and associated mental health issues. 

De-addiction centres

Structured programs offer counseling, behavioral therapy and rehabilitation. 

Family and social support

Encouragement from family plays a crucial role in recovery. Recovery is not easy, but it is achievable.

What can society do?

While individual responsibility matters, societal measures are equally important:

• Restricting alcohol advertising

• Regulating availability

• Reducing glamorisation in media

• Reviewing practices such as routine serving of alcohol

Public health policies that reduce overall consumption have been shown to save lives and reduce harm.

Alcohol is deeply embedded in social culture, but that does not make it harmless. It quietly damages the body, disrupts families and burdens society. The good news is that this is one of the few major health risks that is entirely preventable. Choosing not to drink or choosing to quit is a powerful decision, not just for your health, but for your family, and for society.
