Alcohol Intolerance: Symptoms, Causes & Treatment

Some evidence suggests that post-COVID-19 fatigue syndrome may share characteristics with ME/CFS, a condition where approximately 4 out of 5 people exhibit alcohol intolerance. Unhealthy alcohol use includes any alcohol use that puts your health or safety at risk or causes other alcohol-related problems. It also includes binge drinking — a pattern of drinking where a male has five or more drinks within two hours or a female has at least four drinks within two hours. It is possible to develop worsening symptoms because of an alcohol allergy. While there is no cure for this condition, avoiding alcohol can help you stay symptom-free and avoid an uncomfortable reaction. In contrast, an alcohol allergy tends to be more serious, and if left untreated, can be life-threatening.

  • It is possible to develop worsening symptoms because of an alcohol allergy.
  • The shift has been so abrupt that I begin to wonder if each person is allocated a number of drinks to consume over a lifetime and I had used up all my rations before I’d used up my years.
  • Aldehyde is toxic, and buildup is one of the key reasons people develop symptoms of a hangover.
  • If alcohol intolerance is due to a disease or medication use, successfully treating that disease or stopping the medication will often help resolve alcohol intolerance.

People often confuse alcohol intolerance and alcohol allergy, but they aren’t the same condition. If you have an alcohol intolerance (or a lowered tolerance) but are struggling to give up alcohol, get in touch with Ria Health for further advice and guidance. Those with lower alcohol tolerances do not need to worry, but should still be aware of their limitations and drink appropriately if they choose to drink. It may be a good idea for those with a full alcohol intolerance to see a doctor to rule out any potential medical causes, and to undergo allergy testing. Keep in mind that not being able to stomach alcohol like you used to is not the same thing as having an allergy to alcohol.

Changes in alcohol tolerance over time

If it is an inherited genetic condition, medical professionals are limited to providing ways to reduce the unpleasant symptoms of alcohol intolerance. Alcohol intolerance is a rare condition in which your body cannot process alcohol correctly, leading to a build-up of a chemical called acetaldehyde. High levels of acetaldehyde are what cause the unpleasant symptoms of alcohol intolerance.

Allergy testing can also tell you if you have an allergy to another component of alcoholic beverages like wheat, grapes, or barley. Individuals may also explore alternative alcoholic beverages or nonalcoholic options that they can tolerate. They may also find that eating certain foods, taking supplements, or exercising may help with their reaction. They may also discuss possible medications for their reactions, such as antihistamines.

When to see a doctor

If you’re starting a new medication, it’s always a good idea to talk with your healthcare provider or pharmacist about how your medication can interact with alcohol. Some people don’t have enough of an enzyme called aldehyde dehydrogenase (ALDH). A true allergic reaction happens when your immune system goes into overdrive what causes alcohol intolerance to attack something it sees as a threat. Allergic reactions can cause hives, facial swelling, nausea, and vomiting. Over time, a person’s tolerance may also change due to changes in metabolism, body mass, and bodily functions as they age. Alcohol intolerances are usually genetic but may also occur without a known cause.
