As an asthma patient, there are actually many foods that need to be avoided. So can people with asthma eat seafood? Below I will introduce to you, can people with asthma eat crabs? Can people with asthma eat seafood?
Can people with asthma eat crabs?
People with asthma are best not to eat crabs. Crabs are rich in protein, and asthma patients are prone to allergies after eating them. A severe asthma attack can cause hypoxia, leading to serious consequences such as heart failure. Seek medical attention promptly after the onset. After eating crab, because crab protein is a foreign protein, after entering the gastrointestinal tract, the body produces immunoglobulin E (IgE) in response to foreign antigens. IgE combines with mast cells to become sensitized cells. When the antigen invades again, it combines with the sensitized cells and causes the sensitized cells to release biologically active substances, such as histamine, prostaglandins, etc., causing a series of reactions in the body, manifested in the gastrointestinal tract, such as nausea, vomiting, abdominal pain, diarrhea, etc. , manifested in the respiratory tract, bronchial smooth muscle spasm occurs, which can induce asthma. Therefore, it is best not to eat crabs for asthma to avoid aggravating the condition of asthma.
Can asthma eat seafood?
Each patient’s seafood allergens are not exactly the same, and it is not necessary to avoid all seafood. Asthma patients can also undergo planned desensitization to seafood types they are allergic to. In recent years, the incidence of eczema has been on the rise, which may be related to changes in climate and environment, the application of a large number of chemicals in life, mental stress, accelerated pace of life, and changes in dietary structure.
Many asthma patients directly or indirectly cause asthma attacks after eating seafood. For example, Ms. Wang from a certain city had a history of asthma. When she congratulated her mother on her birthday, she ate several crabs and drank wine on a whim. Unexpectedly, after drinking a glass of wine, I suddenly coughed non-stop and complained of chest tightness. Soon my lips turned purple and I felt dizzy. After being rushed to the hospital for examination, he was diagnosed with an allergic asthma attack caused by eating seafood and drinking alcohol. After being rescued by doctors, he was out of danger. For such patients, patients should try to avoid eating seafood.
So, does it mean that if you are allergic to seafood, you cannot eat seafood at all? In fact, this is not the case. The seafood allergens of each patient are not exactly the same, and it is not necessary to avoid all seafood. Asthma patients can also desensitize the types of seafood they are allergic to in a planned way: when asthma has not occurred for half a year, they can eat a small amount of seafood, and then gradually increase it to the usual amount. For example, for shrimp desensitization, eat 1~ 2, eat 2 to 4 in the second week, 4 to 8 in the third week, and about 10 in the fourth week. Through this process, patients gradually develop immune tolerance to food, which plays a role in desensitization.
Dietary Notes for Asthma
1. Add more water on weekdays. Drinking plenty of water can keep the respiratory mucosa moist and effectively resist bacterial invasion. Especially in the dry seasons of spring and autumn, there is a lot of dust, and the nasal mucosa is easily dry and damaged, so you should pay more attention to replenishing water.
2. Eat more vegetables and fruits. Vegetables and fruits contain a lot of water and can replenish water. Fruits and vegetables are light foods that can reduce inflammation and moisturize the respiratory tract to prevent dryness.
3. Avoid eating allergic foods. Bronchial asthma is mostly caused by allergic factors. People with some allergies should pay attention to eating less or not eating fish, shrimp, crab, eggs, milk, and raw and cold foods to avoid triggering asthma. Patients should usually know which foods they are allergic to. Once they find out which food triggers asthma, they should avoid eating it.
4. Eat less acidic foods such as salt and vinegar. A high-salt diet will increase bronchial reactivity, so you should mainly eat light foods. Silk and acidic foods are irritating to the bronchial tubes and can also trigger or aggravate asthma.
5. The patient must abstain from smoking and drinking. Because tobacco and alcohol are highly irritating substances, smoking or drinking will irritate the bronchial wall, cause spasm, increase secretions, damage the mucosal epithelium, and aggravate asthma.
6. Environmental health. Do not hang thick velvet accessories or place carpets indoors to prevent the mites in these items from being sucked into your mouth and causing asthma. Always open windows indoors for ventilation to keep indoor air fresh. Bedding should be exposed to the sun frequently to keep it dry and kill bacteria. Do not keep pets. The fur, secretions and excretions of dogs, cats, birds and other pets can induce asthma.
Stay away from allergens. Patients with allergic asthma are mostly caused by contact with allergens, such as paint, dust, pollen, gasoline and other substances in the environment, which are closely related to inducing asthma. Patients should stay away from these substances.
How to treat asthma
Drugs to treat asthma are mainly divided into two categories:
(1) Drugs to relieve asthma attacks, which mainly act as bronchodilators.
1) β2 adrenoceptor agonist: It can relax bronchial smooth muscle and is the drug of choice for controlling acute attacks. Commonly used drugs include: albuterol, terbutaline, fenoterol, formoterol, etc.
2) Anticholinergic drugs: Commonly used drugs include atropine, scopolamine, 654-2 and ipratropium bromide.
3) Theophylline drugs: aminophylline.
(2) Drugs to prevent and control asthma attacks. Mainly used to treat airway inflammation in asthma.
1) Glucocorticoids:
Inhalants: beclomethasone, budesonide, mometasone, etc.;
Oral agents: prednisone, prednisone Nylon.
Intravenous medication: dexamethasone, etc.
2) Other drugs: ketotifen, astemizole, etc.
