While a glass of wine is often celebrated for its health benefits, it can pose significant risks for individuals with asthma. Compounds like sulphites and histamines, commonly found in wine (especially red wine), are known to trigger asthma symptoms. These substances can exacerbate mild symptoms and potentially lead to more severe reactions in asthma patients.
It's not just wine—beer and cider can also provoke asthma symptoms in those already diagnosed. So, before you indulge in a pint of beer or savour a sip of premium wine, be mindful of how it might affect your health if you have asthma.
Why Asthma Patients Should Avoid Wine
Asthma is a chronic respiratory condition that involves inflammation and narrowing of the airways. The triggering factors may be environmental or dietary. Management of triggers is an important factor for asthma patients in maintaining lung health and preventing exacerbations. Although wine, especially red wine, has been hailed as a health promoter in moderation, it poses particular risks to asthma patients and needs caution.
Sulphites in Wine
One of the major issues for asthma patients who drink wine is sulfites. Sulphites are chemical preservatives added to wine to prevent oxidation and extend shelf life. For some people, especially asthma patients, sulphites can cause respiratory symptoms such as wheezing, coughing, and difficulty breathing. It is estimated that between 3% and 10% of asthma patients are sensitive to sulphites, which makes wine consumption dangerous for this group.
Histamines and Allergic Responses
Histamines are naturally occurring compounds in red wine. These are byproducts of fermentation, and they cause symptoms that may be similar to an allergic reaction in sensitive individuals. In asthma patients, histamines may cause more pronounced airway inflammation and breathing difficulties.
Alcohol and Airway Reactivity
Alcohol itself can be a vasodilator, which might increase airway reactivity. In some individuals, alcohol can increase asthma symptoms such as chest tightness and shortness of breath. This is thought to be particularly more significant in people whose respiratory function is compromised.
Interaction with Asthma Medications
Many asthma patients depend on bronchodilators and corticosteroids as part of the treatment for asthma. Alcohol in wine can disrupt the metabolism of these drugs, reducing their effectiveness. Alcohol also may worsen side effects from certain asthma drugs, such as dizziness or nausea, which can make the disease harder to control.
