What does it mean if there is phlegm with blood in the throat, and what should I do?

In general circumstances, the term "throat" refers to the pharynx. The presence of blood in phlegm from the throat may be related to dryness of the pharyngeal mucosa, severe coughing, acute pharyngitis, bronchiectasis, or pulmonary tuberculosis. It is recommended to seek timely medical advice and undergo general treatment or medication under a doctor's guidance. A detailed explanation is as follows:

1. Dryness of Pharyngeal Mucosa

When the pharyngeal mucosa becomes dry, the tiny blood vessels on the mucosal surface are prone to rupture, which may result in blood streaks in the sputum when coughing. It is important to rest regularly and keep the throat moist, avoiding prolonged voice use.

2. Severe Coughing

During severe coughing, the mucous membranes of the throat and trachea may be subjected to vibration, potentially causing localized blood vessels to rupture and bleed, resulting in blood-streaked sputum. Wearing a mask when going outdoors can help prevent respiratory diseases.

3. Acute Pharyngitis

Acute pharyngitis is usually caused by bacterial or viral infections. Inflammation leads to congestion and edema of the pharyngeal mucosa, and phlegm may contain blood streaks. Symptoms typically include sore throat, difficulty swallowing, and hoarseness. Treatment may involve medications such as Fengre Kang Capsules, Qinghou Lixiang Granules, Jinlang Voice Capsules, or similar drugs, as directed by a physician.

4. Bronchiectasis

Bronchiectasis results from chronic inflammation and fibrosis of the bronchi and surrounding lung tissue. Bronchiectasis can easily lead to rupture of blood vessels in the bronchial walls, causing blood in the sputum. It is generally accompanied by chronic cough, expectoration of large amounts of purulent sputum, and recurrent hemoptysis. Treatment may involve medications such as aminophylline sustained-release tablets, levofloxacin hydrochloride tablets, levofloxacin tablets, or similar drugs, as prescribed by a doctor.

5. Tuberculosis

Tuberculosis is caused by infection with Mycobacterium tuberculosis. The tuberculosis lesion may erode blood vessels, leading to hemoptysis or blood-streaked sputum. Symptoms may also include prolonged low-grade fever, night sweats, and fatigue. Treatment may involve medications such as isoniazid tablets, rifampin tablets, ethambutol hydrochloride capsules, or similar drugs, as recommended by a doctor.

Maintaining healthy lifestyle habits is essential, including a low-salt, low-fat diet, quitting smoking, limiting alcohol consumption, and avoiding spicy or greasy foods to maintain overall health.
