Hemoptysis can be considered one of the common symptoms of lung cancer. However, not everyone with lung cancer experiences coughing up blood. In fact, experts believe that if lung cancer is advanced, the possibility of coughing up blood increases. In general, the cause of coughing up blood in lung cancer can be attributed to the following reasons: - **Lung tumor:** The person coughs up blood due to tumor bleeding. - **Lung infection:** Lung infection is one of the common complications of lung cancer and it usually appears in the form of coughing up blood. - ** Stimulation and inflammation of airways: ** Lung cancer inflames the airways and respiratory tracts, which results in coughing up blood. - **Blood clot:** Blood clot in the lung is one of the other causes of coughing up blood, which usually occurs rarely. Symptoms of coughing up blood The most important symptoms of hemoptysis include the following: - Discharge of bright red blood with cough - Thin, coagulated or frothy blood This complication may occur due to various disorders and diseases (from cancer to bronchial infection). Most people experience whooping cough with other symptoms, which include: - shortness of breath - Chest pain - Fever - Takipene (very sharp breathing) - Nausea and vomiting If you are being treated for an allergic cough, take symptoms such as coughing up blood seriously. Coughing up blood on its own is dangerous and requires more careful investigation if it is accompanied by other types of cough as symptoms. When should we see a doctor for coughing up blood (hemoptysis)? If blood comes out of your respiratory tract along with coughing, be sure to see an infectious disease doctor. People with bronchitis usually experience coughing up a small amount of blood, otherwise coughing up blood can be a sign of a serious illness. If you experience any of the following symptoms, go to the emergency room immediately: - Presence of blood in the mucous membrane for more than a week - Chest pain - Unexplained weight loss - Severe night sweats - Fever above 40 degrees Celsius Shortness of breath without intense activity Is coughing up blood in children dangerous? Doctors specializing in infectious diseases believe that this complication in children is dangerous and should be taken seriously. Bleeding from the respiratory tract with severe coughing usually occurs due to a serious illness. After seeing it in their young child, parents should immediately go to the doctor to find out the main cause of this complication while treating children's cough. In the past, hemoptysis in children was mostly caused by tuberculosis, but now this complication has different causes, the main cause of which can be considered to be infection, trauma due to complications of tracheostomy (intubation) or foreign body aspiration. What is the treatment of whooping cough? The treatment of this condition is a little complicated, unlike the treatment of dry cough, and only antitussive medicine does not work for it. The doctor chooses the treatment of hemoptysis based on the severity of the bleeding and the main cause of hemoptysis, which are tailored to the needs of each person's body and with the aim of stopping the bleeding, including the following: - Antibiotics (in cases of pneumonia and tuberculosis) - Steroids (in case of inflammation) - Surgery (in case of malignant and cancerous tumor) Treatment of this cough is usually not possible with home remedies and traditional medicine unlike the treatment of phlegm cough. If the hemoptysis with coughing is severe, the person should be admitted to the intensive care unit (ICU). In such cases, the doctor uses the following treatment approaches: - Removing airway clots by bronchoscopy - Stopping blood flow in blood vessels with the help of bronchial artery angiography and embolization - Termination of severe bleeding with the help of tranexamic acid drug During the course of treating hemoptysis with one of the above methods, the doctor tries to find out the main cause of this condition. Finally, the doctor offers the best treatment plan to improve the symptoms and the underlying disease causing hemoptysis. Remember, the treatment of this type of cough is different from other coughs and requires serious intervention by a doctor. That's why you can't just use herbal anti-cough pills and syrup as you use syrup for dry cough. > Kausar Pathobiology Specialized Laboratory, proud to obtain ISO 15189, ISO 10002 and ISO 9001 of the European Union, under the supervision of Dr. Ali Ayatollahi, an anatomical and clinical pathology specialist, covers more than a thousand cases of various tests in the fields of pathology, genetics and clinical.
