Mite allergy symptoms
Dust mites are tiny animals that are generally invisible to the naked eye and can only be seen under a microscope. If a dust mite allergy occurs, it can cause many skin symptoms, such as acne, itching, pigmentation, or erythema, severely affecting the patient's quality of life and appearance. Therefore, if a dust mite allergy is present, it is important to pay attention to personal hygiene and skin cleanliness, and maintain ventilation in the house. Treatment can include the use of anti-allergy medications.
How to test for allergens in allergic asthma
Allergic asthma is a subtype of bronchial asthma. As the name suggests, allergic asthma refers to asthma symptoms that are related to contact with external allergens, such as dust, pollen, dust mites, pet dander, etc. When these substances are inhaled into the trachea, they can trigger asthma symptoms. 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.
Drug allergy symptoms
Drug allergies mainly manifest as skin itching, red rash, and papules; severe cases may experience ulceration, exfoliative dermatitis, in the respiratory system it may present as nasal congestion, breathing difficulties, and laryngeal edema; in the digestive system, patients may experience abdominal pain and diarrhea, sometimes accompanied by joint pain and swelling, immune dysfunction, and the occurrence of allergic purpura. Some drug allergies can cause neurological reactions, such as dizziness and headaches. When a drug allergy occurs, immediately stop using the suspected medication, and simultaneously take anti-allergy medications such as loratadine, cetirizine, or administer diphenhydramine via muscular injection. Oral intake of compound glycyrrhizin capsules may be considered. If there is laryngeal edema, it is crucial to seek prompt medical attention at a hospital, actively manage the allergy, and severe cases may require a tracheotomy for rescue. (Specific medication usage should be conducted under the guidance of a doctor, and medications should not be used without authorization.)
Symptoms of alcohol allergy shock
Patients with an allergy to alcohol can experience allergic shock, exhibiting symptoms like chest tightness, palpitations, a sensation of throat blockage, breathing difficulties, and a flushed face. Additional symptoms include dry mouth, dizziness, blurred vision, numbness in the face and limbs, and circulatory system failure, indicated by chills, cold sweats, cyanosis, restlessness, a weak pulse, and even a drop in blood pressure. Some patients may also experience loss of consciousness, coma, convulsions, and incontinence. Due to the alcohol allergy, patients may show allergic reactions like skin itching, hives, or other rashes. A minority of patients may also have abdominal pain, diarrhea, nausea, vomiting, sneezing, and fever.
Do you need to check for allergens for allergic rhinitis?
Allergic rhinitis is a type of hypersensitivity disease. The first thing we need to know about allergic rhinitis is that it requires allergen testing. Traditionally, the diagnosis of allergic rhinitis is based on clinical symptoms, without involving etiological diagnosis. Testing for allergens is aimed at diagnosing based on its etiology. Secondly, we need to be aware of the allergens responsible for allergic rhinitis, which include food allergies and asthma-related allergies. By identifying food allergens, we can avoid consuming these substances in daily life. For instance, if one is allergic to fish and seafood, they should avoid eating these foods. Similarly, if allergic to mangoes, one should also avoid mangoes. Thus, overall, it is necessary to identify the sources of allergens in allergic rhinitis.
Symptoms of baby food allergies
Babies generally start adding supplementary food between four to six months old. Some children may exhibit symptoms after introducing additional foods, which resemble those caused by allergies. These symptoms primarily appear on the skin, in the oral cavity, digestive tract, and respiratory tract. They might present in one area or multiple areas. The most common symptoms include constipation, bloating, vomiting, diarrhea, and pain. Additionally, manifestations on the skin can include eczema, severe cases may develop urticaria or other types of allergic dermatitis.
How to Test for Allergens in Allergic Rhinitis
Allergic rhinitis is considered an autoimmune disease, mainly triggered by the body's immune response after contact with allergens, leading to related clinical symptoms such as itchy nose, runny nose, and sneezing. Generally, it is necessary to conduct an allergen test. Currently, there are mainly two methods for allergen screening. The first is the skin prick test, and the second is a blood test. Both methods are commonly used clinically. Relatively speaking, the skin prick test may induce higher risks of side effects or allergies. Some patients may need to undergo both tests and look at the results comprehensively, but most patients can choose one of the two.
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 to find allergens for skin allergies?
When skin allergies occur, the allergen is the root cause of the condition. Therefore, it’s essential to promptly identify the allergen. To find the allergen, it is recommended to conduct several tests such as patch tests, allergen screening, trichophytin tests, as well as provocation tests and slide compression diagnostic methods. Regardless of the method used, the approach varies from one individual to another.
When is the best time to check for allergens in allergic asthma?
The best time to check for allergens in allergic asthma is still during an asthma attack. At this time, due to the body's strong immune response to external allergens, also referred to as a hypersensitive reaction, checking for allergens can likely yield some positive results. However, there are many methods for screening allergens, such as drawing blood to check for IgE antibodies, or using skin prick tests to assess reactions to different allergens. However, if it is during the acute phase of an asthma attack, it is recommended to use the blood drawing method, which is relatively safer. Using skin prick tests might exacerbate the patient's allergic reaction, and may even lead to an acute asthma attack, or severe asthmatic conditions. Therefore, there are significant considerations to be made when choosing different methods for allergen testing.
