Can bronchial asthma cure itself?
Bronchial asthma generally cannot heal on its own. Bronchial asthma is a chronic, recurrent disease, which is usually incurable. Even with standard treatment, a complete cure is often unachievable. However, during an acute attack of bronchial asthma, spontaneous remission is possible. Some mild acute attacks of bronchial asthma may simply require removing the allergen and hazardous factors, which can lead to spontaneous alleviation of the asthma symptoms. For bronchial asthma, long-term standard treatment is usually required, such as the inhalation of corticosteroids and the use of bronchodilators. Additionally, it is important to avoid allergens and prevent respiratory infections.
How long will a cold with a runny nose last?
The symptoms of a cold with a runny nose generally recover within seven to ten days. A runny nose during a cold is usually caused by a viral infection. For viral colds, the condition of the patient is generally self-limiting. The natural course of the illness is usually seven to ten days, so the symptoms of a runny nose usually recover within this timeframe. However, for patients with a cold, there is often also a symptom of coughing. Although in most cases, the cough also eases within seven to ten days, some patients with colds may experience persistent coughing symptoms that can even last for one to two months. This condition is referred to as post-cold cough or post-infectious cough.
Is acute bronchitis serious?
Patients with acute bronchitis usually do not experience severe conditions. Acute bronchitis typically presents symptoms of dry cough and is generally self-limiting, usually not leading to severe consequences. However, it is important to note that patients with acute bronchitis may sometimes experience significant chest tightness and wheezing, which can be particularly prominent in children and may even lead to respiratory failure. Additionally, acute bronchitis can sometimes be associated with other conditions, such as bacterial pneumonia. If combined with bacterial pneumonia, it could also lead to severe complications like respiratory failure. In such cases, the patient's condition is relatively severe, and close observation of the condition is necessary.
Is wind-heat cold contagious?
"Wind-heat cold" is a term used in traditional Chinese medicine (TCM) and diagnosed through TCM methods; from a Western medicine perspective, it could also be a viral infection. Viral colds can be contagious, so sometimes, wind-heat colds may be contagious as well. Therefore, it is necessary to take certain measures to prevent the spread of the disease, especially for vulnerable groups such as the elderly, children, and pregnant women. It's advisable for these groups to avoid contact with individuals who have a wind-heat cold to prevent infection. There is also a need to be cautious of the possibility of bacterial infections in such cases. If the patient has a bacterial infection, active treatment, potentially including antibiotics, may be required.
How is pulmonary embolism caused in young people?
Common causes of pulmonary embolism in young people include the following aspects: First, fractures, especially fractures of the lower limbs, are prone to deep vein thrombosis and pulmonary embolism; Second, thrombophilia, some young people due to congenital genetic factors, which can lead to easy formation of blood clots in arteries or veins, and potentially increase the incidence of pulmonary embolism; Third, prolonged immobilization, such as long periods of sitting, can lead to slow blood flow in the lower limbs, which might result in deep vein thrombosis and pulmonary embolism; Fourth, other factors like severe infections could also trigger pulmonary embolism; furthermore, the risk of pulmonary embolism is also higher in pregnant women during the perinatal period.
The difference between bronchial asthma and pulmonary emphysema.
Bronchial asthma and emphysema are two different diseases. Bronchial asthma typically manifests as episodic coughing, chest tightness, and wheezing. Patients often develop this condition in childhood and adolescence, and it is relatively rare in the elderly. Emphysema, on the other hand, is often related to long-term smoking and is usually seen in middle-aged and older patients. Early stages of emphysema may only be evident on a chest CT and may not show significant symptoms of chest tightness. However, as the disease progresses, patients often experience noticeable chest tightness and difficulty breathing, and the condition tends to progressively worsen. Patients typically eventually develop complications such as chronic respiratory failure and chronic pulmonary heart disease. Therefore, the characteristics of bronchial asthma and emphysema are different. However, it is important to note that in patients with bronchial asthma, if the condition is not controlled and continues to progress, it might also lead to the development of emphysema, chronic respiratory failure, pulmonary heart disease, and other related conditions.
What are the symptoms of pleurisy?
Pleurisy often presents with symptoms of chest pain, which tends to worsen with deep breathing. Patients with pleurisy may also experience a feeling of tightness in the chest, possibly caused by a significant accumulation of fluid in the chest cavity due to the pleurisy. Sometimes, this tightness could also be due to severe chest pain that makes the patient reluctant to inhale deeply. Patients with pleurisy are likely to exhibit symptoms of fever. It is important to note that pleurisy caused by different factors may have distinct clinical features. For example, purulent pleurisy often presents with high fever, while tuberculous pleurisy may show symptoms of tuberculosis intoxication like low-grade fever in the afternoon and night sweats. However, some cases of tuberculous pleurisy might present with high fever, and others may not have noticeable fever at all. Additionally, viral pleurisy usually features prominently painful symptoms in the chest.
Can you eat oranges with an upper respiratory tract infection?
Upper respiratory infections can include orange in the diet; these infections are usually viral, and typically there are no specific therapeutic drugs available, only symptomatic treatment is provided. Additionally, patients should also consider eating some fruits and drinking more plain water while maintaining a light diet; fruits like oranges and apples are suitable. Furthermore, patients with severe symptoms of upper respiratory infection may also need to use some cold medicines to alleviate their symptoms. Generally, upper respiratory infections are self-limiting, and patients can gradually recover with symptomatic treatment and dietary adjustments mentioned above. However, it is important to note that some upper respiratory infections may be bacterial, such as acute suppurative tonsillitis, which is a bacterial infection and requires anti-infection treatment.
Does bronchial asthma have wheezing sounds?
During an acute attack of bronchial asthma, patients often have wheezing sounds in their lungs, but it's important to note that some patients may not exhibit wheezing, such as those with chest tightness or cough variant asthma, who only show symptoms of chest tightness and typically do not have wheezing on auscultation. However, administering inhaled corticosteroids and bronchodilators can relieve their condition. Additionally, during a severe acute attack of bronchial asthma, severe airway spasms can occur, leading to a situation where the patient might not have any wheezing sounds, a condition referred to as "silent lung." In such cases, patients often experience difficulty breathing or even respiratory distress, which is usually quite serious and requires active intervention.
What should I do if I have a heavy nasal voice due to a cold?
Cold with nasal voice, in most cases, does not require special treatment. A cold can cause symptoms such as runny nose, sneezing, nasal congestion, sore throat, and coughing. These symptoms can lead to a nasal voice in patients, and this condition usually does not require special treatment. If the symptoms of runny nose, sneezing, and nasal congestion are particularly severe and affect the patient's daily life, some compound cold medicines can be used to alleviate the symptoms, such as compound cold medicines like Ammaminamide tablets. Additionally, for a heavy nasal voice due to a cold, it is also necessary to assess the patient's condition. If the patient has a lot of purulent nasal discharge and is accompanied by headaches, it is important to be alert to the possibility of sinusitis, which also needs to be treated. (Please use medication under the guidance of a doctor.)
