Bronchial asthma is very common in clinical settings, mainly characterized by a reversible airflow limitation that can cause recurrent attacks of wheezing, chest tightness, and shortness of breath in patients. These attacks generally occur at night or in the early morning and can gradually ease after treatment. Bronchial asthma is mainly related to several factors, the first being environmental factors. Exposure to pollen and animal dander can trigger asthma attacks. Additionally, infections, diet, and medications are among the various factors that can provoke asthma attacks.

Can people with bronchial asthma eat beef?

Bronchial asthma is a very common disease in the respiratory system, caused by a multitude of triggering factors. It usually occurs in infants and young children due to their lower immune function, combined with some being of an allergic constitution. Additionally, such patients might also be affected due to exposure to harmful gases in the external environment, which can trigger an asthma attack at any time. Clinically, it is generally advised that patients with bronchial asthma avoid consuming spicy and stimulating foods, though beef can generally be consumed. Beef has high nutritional value, containing a significant amount of amino acids, high-quality proteins, as well as nutrients like calcium and iron, which are essential for the body. Therefore, it is suitable for patients with bronchial asthma to consume some beef appropriately.

Can bronchial asthma be inherited?

The etiology of asthma is still very unclear, but genetics may indeed be related to bronchial asthma to some extent. Currently, a lot of research data indicates that the incidence rate of bronchial asthma is higher among the relatives of patients than in the general population, and the closer the familial relationship, the higher the incidence rate and potentially more severe the condition could be. In layman's terms, this means that if our parents have bronchial asthma, then the likelihood of their children having bronchial asthma is higher than in the general population. However, this is not absolute; it does not mean that if a parent has bronchial asthma, their children will definitely have it. The relationship is not very certain, and the genes related to bronchial asthma are also not very clear at present. Bronchial asthma is also related to many other factors.

Is bronchial asthma contagious?

Is bronchial asthma contagious? Bronchial asthma is not contagious; it is not an infectious disease. The exact causes of bronchial asthma are not very clear, primarily thought to be related to genetic and environmental factors. Bronchial asthma has a close relationship with genetics, meaning that if parents have asthma, their children and grandchildren might also develop bronchial asthma. The closer the familial relationship, the higher the chances of developing bronchial asthma compared to the general population. This genetic pattern can create the illusion to the general public that bronchial asthma is contagious, but it may be more closely related to genetics.

What are the complications of bronchial asthma?

The complications of bronchial asthma are divided into acute and chronic complications. Acute complications, which occur during a severe asthma attack, mainly include pneumothorax, mediastinal emphysema, severe hypoxia, respiratory failure, leading to severe arrhythmias, electrolyte disturbances, and in severe cases, coma and death. Chronic complications are mainly due to chronic changes in bronchial asthma leading to airway remodeling, chronic airway inflammation, and chronic narrowing. The complications at this stage mainly include chronic respiratory failure and pulmonary heart disease.
