If a patient is allergic to alcohol, the following symptoms may occur: the patient will feel itchy all over, their skin will turn red, and they may experience welts and rashes. Some patients may also experience chest tightness, shortness of breath, palpitations, dizziness, and even fainting, profuse sweating, and transient loss of consciousness. If a patient exhibits profuse sweating along with transient fainting and loss of consciousness, this indicates a severe condition that requires emergency medical treatment at a hospital. Anti-allergic measures should be taken to alleviate the allergy symptoms. Additionally, due to the allergy, the patient may experience a relative insufficiency in blood volume, necessitating fluid replenishment treatment. Therefore, patients with an alcohol allergy should avoid exposure to alcohol to prevent triggering allergic symptoms and endangering their lives. (Medications should be used under the guidance of a doctor.)

Alcohol allergy causes

Alcohol allergy, also known as ethanol allergy, occurs because normally, ethanol in the body is converted into acetaldehyde. People with alcohol allergies lack the enzyme needed to convert acetaldehyde, therefore cannot expel acetic acid from the body, resulting in acetaldehyde poisoning and various allergic symptoms. People who can consume large amounts of alcohol usually have a higher amount of this acetaldehyde converting enzyme, allowing them to quickly convert it without experiencing poisoning or allergic symptoms. Alcohol allergies are mostly linked to an allergic constitution; thus, individuals with this constitution will display various allergic symptoms upon exposure to alcohol, the allergen.

How to test for allergens in allergic rhinitis?

Allergic rhinitis is very common in daily life, and its main trigger is the inhalation of allergens in the air by patients. In the south, the allergens are mostly mite allergies, with an incidence rate of over 90%. In daily life, allergic rhinitis can also be caused by food, hair, pollen, and other allergens. The most common method to identify allergens for allergic rhinitis is the use of an allergen test kit, through a skin prick test to determine the patient's allergens and the degree of allergy, etc. A series of targeted anti-allergy treatments can then be carried out to achieve a cure for allergic rhinitis.

What are the allergens for allergic cough?

Allergic cough can be triggered by many allergens. For example, during pollen allergy seasons, one may react to pollen, and it is also possible to react to dust mites, dust, animal dander, paint, feed, and foods that may include allergens like seafood, eggs, and milk. Cold air can also trigger reactions in patients with allergic cough. When individuals with allergic cough come into contact with the aforementioned allergens, it may enhance the reactivity of their airways, causing persistent spasmodic contraction. As a result, patients may experience persistent, irritating dry coughs. In such cases, it is advised to promptly remove oneself from exposure to the allergens and take antihistamines orally, such as loratadine. It is also advisable to avoid contact with these allergens routinely to prevent the onset of allergic cough. (Please follow the doctor's prescription when using medications.)
