Is coughing severe in the early stages of lung cancer?
Patients with lung cancer in the early stages may experience severe coughing, mild coughing, or no coughing symptoms at all. Many early-stage lung cancer patients have lesions located near the periphery of the lungs that do not involve the airways or other significant structures, typically resulting in no clinical symptoms. By the time clinical symptoms appear, the patient may already be in the middle or late stages of lung cancer. Additionally, it is important to note that some patients with early-stage lung cancer may also experience coughing, which can range from severe to mild, and may include coughing up blood. Such symptoms are often seen in early-stage central lung cancer, which frequently presents with cough and blood in the sputum. Therefore, older patients with a long history of smoking who suddenly develop a cough or start coughing up blood should be highly vigilant and likely need to undergo chest CT scans, bronchoscopy, and other related examinations for evaluation.
What is the difference between a hot cold and a cool cold?
Cold from the perspective of Traditional Chinese Medicine is classified into two types: Wind-Heat Cold and Wind-Cold Cold. A Wind-Heat Cold may present symptoms such as coughing, coughing up yellow phlegm, yellow nasal discharge, sore throat, and fever. In contrast, a Wind-Cold Cold typically manifests as clear nasal discharge, dry cough or coughing up white phlegm, along with aversion to cold, headache, muscle soreness, and possibly a mild fever. Clinically, Wind-Cold Cold and Wind-Heat Cold are distinct and should be diagnosed under the guidance of a Traditional Chinese Medicine practitioner who can prescribe specific herbal treatments based on the patient’s symptoms. From a Western medicine perspective, symptomatic treatment is generally recommended. However, it is crucial to assess if the patient exhibits symptoms such as purulent phlegm, high fever, or persistently unimproved cold symptoms, which may indicate the need for a hospital visit to investigate potential bacterial infections that might require antimicrobial treatments.
Can you eat taro with acute bronchitis?
Patients with acute bronchitis can appropriately eat taro, but it is recommended that they avoid spicy, greasy, and cold foods; however, eating taro is still acceptable. Patients with acute bronchitis should also avoid drinking alcohol, coffee, strong tea, and smoking. Additionally, they should avoid excessive fatigue, staying up late, and other similar situations. For acute bronchitis patients, it's important to provide symptomatic cough treatment and monitor their condition. Although some acute bronchitis cases are caused by viral infections, and most patients have viral infections, these patients do not necessarily require antibiotic treatment. However, if a patient has conspicuous purulent sputum, it could be an indication of bacterial bronchitis, or even a possible complication with pneumonia, and these conditions require active investigation and might need anti-infection treatment.
What should you not eat when you have a cold?
When you have a cold, you should avoid eating spicy, overly greasy, and cold food. These foods may worsan coughing symptoms and can also irritate the gastrointestinal tract. Generally, they are detrimental to the patient's condition. For a cold, it is recommended to have a light diet and eat some fruit appropriately, as well as drink plenty of plain water. Additionally, patients can consume some protein-rich foods, such as lean meat and eggs. Cold is usually a self-limiting illness and often does not require special treatment. Sometimes, just by making the dietary adjustments mentioned, the patient's condition may gradually improve. However, it is important to note that if the symptoms of the cold are severe, appropriate symptomatic treatment is necessary. Also, a minority of cold patients may develop complications such as pneumonia. Therefore, if cold symptoms persist, it is necessary to seek medical consultation to investigate the cause and receive appropriate management.
Does lung cancer cause a dry cough and a feeling of stuffiness?
Lung cancer can present symptoms of chest tightness along with dry cough, or it may simply manifest as dry cough alone. Some early-stage lung cancers might only involve dry cough without other symptoms like chest tightness or breathing difficulties. However, for patients with advanced lung cancer, in addition to dry cough, symptoms may include chest tightness and breathing difficulties. Advanced lung cancer can compress the patient's major airways, leading to narrowing of these airways, and thus cause symptoms such as dry cough and chest tightness. In advanced stages, lung cancer may also be accompanied by a significant accumulation of pleural effusion. In such cases, patients might experience chest tightness and breathing difficulties along with dry cough. Therefore, lung cancer can either solely manifest as dry cough or may also be accompanied by symptoms of chest tightness, particularly in advanced stages, where it is relatively common to have chest tightness along with dry cough.
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.
