How Does Alcohol Affect COPD?

COPD and Alcohol: Can You Drink Alcohol With COPD?

Although the effects of alcohol on the heart, the liver, and the brain are widely known, recent research suggests that the lungs deserve more attention – especially when a lung disorder is involved.

COPD is a specific disorder, but the physical damage is broad and symptoms can be brought on quickly, which means that other substances you use, eat, or drink should be treated with caution.

Learn about how drinking might interfere with your illness, and whether it’s possible for you to safely mix COPD and alcohol.

Can Smoking and Drinking Affect COPD?

The relationship between smoking, drinking, and lung health is difficult to define. There’s been some research in recent years into how drinking affects COPD, but the results have been mixed: although studies repeatedly suggest that heavy drinking makes COPD worse, it’s unclear whether the smoking, drinking, or both are really to blame.

Unfortunately, many studies don’t effectively separate drinking from smoking, which makes it difficult to decipher the exact effect of alcohol on COPD.

For instance, one study published in the journal Chest found that patients who reported binge drinking had a higher chance of experiencing worse COPD symptoms, and another found that people who abused alcohol had a much higher chance of winding up in the emergency room with a COPD exacerbation.

The problem is, the number or frequency of cigarettes smoked during a drinking session could also play a role – and researchers tend not to account for that.


How Does Alcohol Suppress the Respiratory System?

The good news is that alcohol use alone probably won’t lead to more COPD exacerbations or lung damage. There is little evidence to suggest that alcohol acts independently of smoke to weaken lung function. However, when alcohol combines with other pollutants, the results can be very damaging.

When you drink alcohol and expose your body to oxidative stress (in the form of tobacco smoke, air pollution, and other irritating chemicals), you are much more vulnerable to lung injury, due to:

  • Less lung protection. Your lungs use an enzyme called glutathione to protect the tissue from the irritants and harmful chemicals in tobacco smoke. Alcohol greatly suppresses this enzyme, which means the more you drink, the less your body can defend against the smoke you take in. In turn, your COPD symptoms can escalate, and you become more vulnerable to serious lung diseases.
  • Damage to the surface of the lungs. The surface of your lungs are coated with a thin layer called the mucociliary transport system, and it has a big job to do: it picks up mucus, and moves it away from the lungs so they can continue to work efficiently. Alcohol interferes with this membrane, which hampers your lungs’ ability to clean away invasive bodies.
  • Diminished lung capacity. Chronic alcohol abuse leads to changes in lung function, including a decline in total lung capacity, residual volume, and what’s known as forced vital capacity – the amount of air that you can force out of your lungs after taking the deepest breath you can.

Manage Your Drinking to Manage Your COPD

Drinking moderately is always good advice, but if you live with COPD, it becomes a very important rule. The studies mentioned above explain what can happen when you overindulge, but limiting the amount you drink allows you to:

Get the Most out of Your Medication

Alcohol can interfere with many medications, especially glucocorticoids and antibiotics. If you’re taking medication to manage your COPD, even a moderate amount of alcohol can reduce its effectiveness. But alcohol can also increase the power of certain medications, which may endanger your lungs.

Many pain and anxiety drugs become more intoxicating as they mix with alcohol, and that means they can slow your heart rate and breathing to a dangerously low level. In order to reap the symptoms relief and long-term benefits of your medication, follow your doctor’s guidelines closely when it comes to diet and lifestyle.

Enjoy the Benefits of Alcohol Without the Dangers

It’s long been known that a glass of wine a day can help the heart, and it appears that a drink may also improve lung function in both the short-term and the long-term.

Although no studies that have specifically tracked the benefits of moderate drinking for COPD, many doctors believe you can continue to enjoy alcohol – as long as you’re very careful about your drinking habits.

The key point is moderation, which means no more than two drinks a day for men and one drink a day for women. But there are also other things to consider if you’re going to make a careful decision, such as your daily medications, your health history and your stage of COPD, whether or not you still smoke, and any other illnesses you have.

It’s best to remember that alcohol is a drug, and like any of your other medications, you need to work with your doctor to determine an acceptable amount to take. Your doctor may also be able to provide you with more information on the effects of COPD and alcohol.
