Clinically, when testing which substances a patient is allergic to, it is called allergen testing. Common methods include blood tests and skin prick tests, which can be combined for comparison to identify the allergens.

Can an allergic cough be cured by staying away from the allergen?

Allergic cough is a very common type of cough clinically, with many complex triggers. Some triggers may be related to exposure to allergens in the environment, while others may be due to oral medications or certain foods that cause an allergic cough. Therefore, depending on the different triggers, some cases of allergic cough might persist even after removing the allergen, as the severity of allergic cough varies. For mild allergic coughs, some patients may see gradual improvement in symptoms shortly after avoiding the allergen. However, most patients with allergic cough might continue to experience a persistent dry cough even after avoiding the allergen.

How long will it take for allergic asthma to improve after avoiding allergens?

Allergen-induced asthma is a very common disease in clinical practice. The recovery time after exposure to allergens varies from person to person. Some patients, who are less sensitive to certain allergens, usually experience gradual improvement in symptoms after avoiding the allergen, which may take two to three hours. However, some allergens may cause more severe allergic asthma attacks, in which case medication is necessary to manage the symptoms. Commonly, appropriate use of anti-allergy medication and drugs to relieve bronchospasm are required for relief. Therefore, the severity of allergic asthma symptoms caused by different allergens and the individual’s physical constitution varies. Thus, the recovery time after exposure to allergens varies from person to person.

If you are allergic to lobster, will you be allergic to other seafood?

When allergic to lobster, consuming other seafood may also trigger allergies. Therefore, in terms of diet, besides avoiding lobster, other seafood, as well as fruits like mango, should also be avoided. Additionally, when outdoors, it's important to be mindful of the environment to reduce exposure to pollen that can cause allergies. It's also advisable to avoid spicy, sour, or pungent foods and yeast-containing products. Drinking more water and eating fresh vegetables and fruits is recommended. Engaging in regular exercise to strengthen the body can help reduce the frequency of allergic reactions. Furthermore, it is suggested to undergo further medical examinations at a hospital to identify specific allergens and prevent future allergic incidents that could pose dangers. If an allergic reaction occurs after eating, immediate oral administration of antihistamines such as cetirizine or loratadine is necessary to prevent worsening of the condition, or seek immediate medical treatment at a hospital. (Medication should be taken under the guidance of a physician.)
