Mixing Alcohol May Increase Intoxication And Health Risks, Say Experts

Alcohol consumption has long been a part of social culture worldwide, but many still question whether mixing different types—such as beer, wine, or spirits—has more harmful health effects than sticking to just one.

Experts clarify that what matters most is the total amount of alcohol consumed, not the combination. The body breaks down alcohol using enzymes like alcohol dehydrogenase and aldehyde dehydrogenase, which convert ethanol into acetaldehyde, a toxic byproduct.

Mixing alcohol often leads to overconsumption, increasing blood alcohol concentration (BAC) and triggering negative effects.

Short-term impact of mixing alcohol

“The idea that mixing drinks is more harmful is a myth. It’s the volume and pace that matter,” says Kanikka Malhotra, consultant dietician and diabetes educator.

High BAC from mixing drinks may impair judgment, coordination, and reaction time. Fiona Sampat, clinical dietitian at Kokilaben Dhirubhai Ambani Hospital, adds that mixing alcohol increases the risk of intoxication.

Alcohol also acts as a diuretic. When not enough water is consumed, it leads to dehydration, causing headaches and fatigue.

Mixing drinks can irritate the stomach, worsening symptoms like nausea, acidity, and gastritis.

Rising BAC slows brain function, impacting behaviour and motor skills. “This can lead to accidents or dangerous choices,” Malhotra says.

In severe cases, overconsumption results in alcohol poisoning, a life-threatening condition marked by vomiting, confusion, and shallow breathing.

Long-term consequences and at-risk groups

Frequent mixing of alcohol or heavy drinking strains the liver, causing fatty liver, hepatitis, or cirrhosis. Regular intake also harms the stomach lining, leading to ulcers and poor nutrient absorption.

Cognitive decline may occur over time, affecting memory and increasing the risk of Wernicke-Korsakoff syndrome due to Vitamin B1 deficiency.

Sampat adds that excessive drinking also raises the chance of stroke, high blood pressure, and heart disease.

Certain individuals should avoid alcohol entirely. These include pregnant women, people with chronic liver or heart diseases, and those on medications.

“Alcohol can worsen medicine side effects or cause toxicity,” warns Sampat.

Experts recommend mindful drinking habits. Monitor your total intake, stay hydrated, and eat before drinking to slow alcohol absorption.

Avoid switching between types of drinks and know your body’s limits. While abstinence remains the safest option, moderation is key.
