Is variant asthma allergic asthma?
Cough-variant asthma is not allergic asthma, although it is a type of allergic asthma. Generally speaking, there is a certain distinction between cough-variant asthma and allergic asthma. Clinically, cough-variant asthma is a special type of asthma, where the main symptom exhibited by patients is an irritative dry cough, typically quite severe, without other significant clinical discomforts. In contrast, patients with allergic asthma usually exhibit symptoms such as sneezing, nasal congestion, runny nose, itchy eyes, and itchy nose before the onset, triggered by exposure to certain allergens. Cough-variant asthma does not have these preliminary signs, marking a clear difference from allergic asthma.
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.
What should I do if I have a cold and my ears are itchy?
Having a cold accompanied by itchy ears may be due to congestion of varying degrees in the nasal mucosa and the middle ear canal following an upper respiratory tract infection. This condition can worsen when the patient blows their nose or if there is a concurrent bacterial infection, sometimes even leading to otitis media. Therefore, in such cases, patients might experience varying degrees of discharge and itching in the ear canal. It is crucial first to identify the specific pathogen causing the cold and treat it with the appropriate anti-infection or antiviral medications. Once the inflammation is effectively controlled, the symptoms of itchy ears can also be alleviated promptly and effectively.
Can air conditioning cause a fever?
Air conditioning cold, also known as in the hot summer due to staying in air-conditioned rooms for a long time without timely ventilation, and the air conditioning temperature being set too low, over time, will inevitably cause some clinical discomfort symptoms. Typically, if the temperature is too low, it generally causes symptoms of upper respiratory infections, such as nasal congestion, runny nose, sneezing, fever, and even some gastrointestinal discomfort symptoms such as nausea, vomiting, diarrhea, etc. Therefore, it is very common for patients with air conditioning cold to experience fever symptoms. As long as the diagnosis is clear and timely symptomatic treatment is provided, the fever symptoms caused by air conditioning cold can also be effectively controlled.
How dangerous is pulmonary hypertension?
Pulmonary hypertension is itself a very complex disease, with many causative factors in clinical practice. In the early stages, patients may only exhibit symptoms such as shortness of breath after activity, difficulty breathing, and overall fatigue. However, as the condition gradually worsens, patients may experience chest tightness, rapid breathing, and even chest pain, fainting, or dizziness. If the patient also has right heart dysfunction, they may experience symptoms like swelling of the lower limbs, as well as diarrhea and abdominal distension. Therefore, if pulmonary hypertension patients are definitively diagnosed and do not receive timely appropriate treatment, the accompanying clinical symptoms may rapidly worsen. The patient's life may be at risk due to severe symptoms such as hypoxia or fainting.
Does a heat cold fear heat?
Colds are quite common in clinical settings, and from the perspective of Chinese medicine, colds are divided into heat-type colds and cold-type colds. Patients with a heat-type cold do not necessarily feel hot; this type of cold is most common in the summer. The primary symptoms include sore throat and cough, usually with yellow phlegm, runny nose, and nasal congestion, often caused by yellow nasal discharge. Therefore, such patients may not exhibit a clear aversion to cold. Thus, it is appropriate to administer treatments like antiviral and heat-clearing detoxifying medications to address these symptoms, which can provide relief. It is not the case that patients with a heat-type cold will always feel hot. Indeed, if a fever is present, patients with a heat-type cold may even experience feeling cold.
Can pneumoconiosis cause coughing up blood?
Pneumoconiosis is a very common type of occupational disease, caused by many complicated factors. This disease primarily occurs because patients have been exposed to dusty environments for a long period. This disease has a very long course, with the early symptoms in patients mainly being mild coughing. Many patients do not take it seriously initially. As the condition gradually worsens, patients may develop lung infections. Subsequent symptoms become more severe, including coughing, phlegm, shortness of breath, weight loss, and decreased appetite, among others. In severe cases of infection, patients may experience intense coughing, which can lead to bleeding from the capillaries on the surface of the bronchi. Thus, people with pneumoconiosis may sometimes experience coughing up blood.
Do you need to take medicine for a cold with nasal congestion?
Nasal congestion due to a cold is very common in clinical practice. The need for medication depends on the type of cold and the patient's own immune function. If the patient has a cold caused by a viral infection and the symptoms are not severe, or if the patient generally likes to exercise and is young, a mild cold may not require medication and can heal on its own within about a week. For children or elderly individuals with weaker resistance, when an upper respiratory infection occurs, it is advisable to administer some medication for symptomatic treatment to prevent the condition from worsening and to avoid unnecessary complications.
Does the common cold have phlegm?
The common cold, also known as acute upper respiratory infection, is generally caused by a viral infection for most patients. For the first three days before catching a cold, patients typically experience a dry cough without phlegm. After symptoms persist for two to three days, some patients may develop a bacterial infection as well. Therefore, at this point, some patients with the common cold might also experience varying degrees of phlegm production. In the case of the common cold, once a diagnosis is confirmed, it is important to promptly administer appropriate treatments such as antivirals and heat-clearing detoxifying medications to alleviate the acute clinical symptoms of the patient. By effectively alleviating these symptoms, it prevents the patient from developing additional bacterial infections, thus avoiding the occurrence of a cough with phlegm.
Symptoms of bacterial cold
Bacterial cold, commonly referred to as an upper respiratory tract infection, is just one of the more common types of colds. Generally, when bacteria infect the respiratory tract, it causes the patient to experience varying degrees of fever, headache, dizziness, and even chills, as well as symptoms such as sore throat, coughing, and even some nasal congestion. Therefore, patients with bacterial colds generally exhibit these symptoms. Of course, some patients with bacterial colds might have lighter infections and may not exhibit typical clinical symptoms of discomfort. Thus, the clinical symptoms presented by each patient with bacterial colds can vary. For patients with bacterial colds, a clear diagnosis can be made by combining some clinical presentations with related auxiliary examinations.
