How to cure asthma completely
How can asthma be completely cured? First, we need to understand what type of disease asthma is. Currently, most references to asthma pertain to bronchial asthma. Whether allergic, cough variant, or chest tightness variant, so far, no method has been found to completely cure bronchial asthma. It is also predicted that it will be difficult to find a cure for asthma within the next ten or twenty years. Therefore, once diagnosed with bronchial asthma, it is crucial to deeply understand this disease and learn to accept the reality that asthma cannot be completely cured at this point. It is also important to recognize that asthma can be managed. Asthma can only be controlled, not cured. Any advertisement claiming to cure asthma through any means is false and not trustworthy. Moreover, in our practical experience, we often encounter many asthma patients who, through various channels such as search engines, television, newspapers, or magazines, find advertisements for medications claiming to cure asthma. However, in practice, although these patients may find their bronchial asthma symptoms well controlled in the short term after taking these medications, the symptoms of bronchial asthma recur repeatedly after stopping the medication, becoming increasingly difficult to control. Furthermore, some asthma patients who have taken these medications often develop typical drug-induced conditions, such as Cushing's syndrome or drug-induced diabetes. We suspect that these medications likely contain oral steroids. Oral steroids can indeed be used to treat asthma, but their use in the standardized treatment of asthma is governed by very strict guidelines. Therefore, patients with bronchial asthma must not be misled by these false advertisements, otherwise, the consequences could outweigh the benefits.
Is acute bronchitis contagious?
Is acute bronchitis contagious? First, we need to understand what is acute bronchitis. What factors can cause acute bronchitis? It is currently believed that many factors including biological, physical, chemical irritants, or allergies can lead to acute bronchitis. Among these factors, biological factors are the most common, especially infections by microbes, which include viruses, bacteria, mycoplasma, and chlamydia. These can potentially be transmitted to other people through droplets or other methods. Common agents include influenza viruses and chlamydia. Other factors can also cause bronchitis, such as cold air, irritant gases, or smoke irritation, as well as allergens like pollen and dust. These cases generally are not transmitted by infection, so they do not spread to other people.
Symptoms of tuberculosis
Tuberculosis of the lung presents in many forms, as there are also various types of pulmonary tuberculosis, each exhibiting different symptoms. However, the most common symptoms primarily include coughing and expectoration, which are the most typical manifestations of pulmonary tuberculosis. The cough in pulmonary tuberculosis is generally mild, either dry or producing only a small amount of phlegm. If the tuberculosis is accompanied by cavities, the amount of phlegm may be larger. If there is a bacterial infection in addition to the tuberculosis, the phlegm may become purulent. Some patients with pulmonary tuberculosis may also experience hemoptysis, which can vary in amount from light to severe. A small number of patients may suffer from chest pain and difficulty breathing. Additionally, there are systemic symptoms associated with pulmonary tuberculosis, such as fever (both low and high fever may occur), night sweats, and fatigue, among others.
How long can one live with bronchiectasis?
This question is actually very difficult to answer because no doctor can predict exactly how long their patient will live. They can only provide a general prognosis of the disease. Bronchiectasis is relatively a benign condition. The prognosis for most patients depends mainly on the severity of the bronchiectasis and their comorbidities, among other factors. Generally, if a patient’s bronchiectasis is not very severe and mild, and does not affect lung function or is not compounded by other underlying diseases, they might experience long-term, recurrent coughing and sputum production, requiring long-term hospitalization. However, if they do not experience acute complications associated with bronchiectasis, such as asphyxiation caused by hemoptysis, then actually they can live for a long time. There are many patients who are in their seventies or eighties and frequently admitted to the hospital. When asked how long they have had bronchiectasis, their condition might span over forty or fifty years, or even longer. This means that patients with bronchiectasis can live for a long time, provided their condition is relatively stable and they don’t suffer from acute complications such as severe bleeding or asphyxiation. However, if the bronchiectasis is severe, or unfortunately, even if the bronchiectasis isn’t very severe, if a patient suffers from major hemoptysis, it can cause asphyxiation rapidly leading to death within minutes. Therefore, it is impossible for doctors to predict exactly how long each patient will live.
Chronic bronchitis chest X-ray manifestations
Patients with chronic bronchitis may have completely normal chest X-rays or lung CT scans in the early stages, meaning that if a patient exhibits symptoms of chronic bronchitis, such as coughing and expectorating for more than three months continuously or over two consecutive years, they can still be diagnosed with chronic bronchitis even if their chest X-ray appears normal. Additionally, as chronic bronchitis progresses over time, some patients may develop thickening of the bronchial walls or interstitial inflammation in the small bronchioles and alveoli, etc. These conditions can manifest on chest X-rays as coarse, disordered lung textures in a net-like or strip-like pattern, or as patchy shadows, which are generally more evident in the lower fields of both lungs. Observing these changes on a chest X-ray can assist in diagnosing chronic bronchitis. Furthermore, as the disease progresses, some patients with chronic bronchitis may develop into chronic obstructive pulmonary disease (COPD) or pulmonary heart disease, and corresponding changes might be observable on chest X-rays. Additionally, patients with chronic bronchitis often experience acute exacerbations or concurrent infections, which may lead to patchy exudates visible on the chest wall.
Does acute bronchitis cause fever?
First, we need to know that acute bronchitis refers to the acute inflammation of the bronchial mucosa caused by biological, physical, chemical stimulation, or allergens. The main symptoms in most patients are cough and expectoration. The cough usually presents as a dry cough or a small amount of viscous sputum. Over time, the amount of sputum may increase, or the cough may worsen. A small proportion of patients may have bloody sputum. The cough and expectoration can last for two to three weeks, and in very rare cases, some patients may develop chronic bronchitis if the condition does not resolve. However, for most patients, the primary manifestations are still localized, that is, symptoms like cough and sputum. Systemic symptoms, such as fever, generally present mildly.
Does bronchiectasis cause fever?
Patients with bronchiectasis generally do not have a fever. However, if there is an acute exacerbation of bronchiectasis or if there is an additional infection, they might develop a fever. In cases where patients with bronchiectasis exhibit a fever, it generally indicates an infection or that their condition may be more severe compared to those without a fever. Under such circumstances, anti-infection treatment might be required. Moreover, the duration of the fever and its maximum intensity can reflect the severity of the infection to a certain extent.
What department should I go to for pneumothorax?
What department is pneumothorax treated in? For pneumothorax, we commonly see patients first in the emergency department, as the onset of pneumothorax is generally very sudden and the condition can be quite severe. The patient may suddenly experience difficulty breathing, and in most cases, this breathing difficulty is severe. Therefore, patients typically start by seeing the emergency internal medicine department. The doctors there will assess the patient’s condition and will consult with thoracic and cardiovascular surgery and respiratory medicine. If a closed thoracic drainage tube is needed, our surgeons will immediately perform the drainage. If the patient can be treated conservatively, they are usually then transferred to either respiratory medicine or thoracic and cardiovascular surgery for further treatment.
Can bronchial asthma be cured?
Bronchial asthma, to this day, cannot be completely cured. Many places claim under the guise of traditional Chinese medicine or ancient secret recipes that bronchial asthma can be fully cured, but these are false advertisements. So far, bronchial asthma is a manageable disease. Being manageable means that it can be treated; standardized treatment can make its recurrence quite rare, but it still cannot be completely cured. This means that once someone has bronchial asthma, they must understand that it is a lifelong disease, potentially recurring throughout life, and they need to manage it long-term.
Asthma belongs to what department?
When we talk about asthma, we generally refer to bronchial asthma, which is a respiratory system disease. Therefore, the primary department to consult is, of course, the Department of Respiratory Medicine. If an asthma patient's condition is relatively stable, they can see a respiratory specialist through outpatient services. In hospitals without a Department of Respiratory Medicine, such as community health service centers or township health clinics, they can choose to see a general practitioner, also known as an internist. If an asthma patient suffers an acute attack of bronchial asthma and the condition is critical, they must then visit the Department of Emergency Medicine. The emergency department will decide based on the patient’s condition whether they should be kept for observation in the emergency room, be admitted to the general respiratory department, or be sent to the ICU for further emergency treatment. Additionally, there is another type of asthma known as cardiac asthma, which is a cardiovascular disease. The first choice for these patients is to see a cardiologist, although in severe cases, they should visit the Department of Emergency Medicine.
