The weather is dry, coughing up blood and phlegm

Online Navigation of Otolaryngitis by Family Doctors

How is blood in phlegm? Air drying is still the main reason.

Many patients with pharyngitis have encountered blood in sputum. Some people are nervous, and many patients have serious blood in their sputum. So what about blood in sputum? Need special attention?

Most of the blood in the mouth comes from three parts.

1, lower respiratory tract

The lower respiratory tract refers to the trachea, main bronchus and bronchus at all levels in the lung, which is the channel for air flow when the lung breathes. The blood in the lower respiratory tract often coughs up, which is called "hemoptysis" in medicine. The patient's symptoms of hemoptysis indicate that the lower respiratory tract is diseased.

2. Digestive tract

The throat is connected with the trachea and esophagus. If there is a lesion in the stomach or esophagus, hematemesis will occur, which is called "hematemesis" in medicine. Patients with hematemesis symptoms indicate that there are lesions in the esophagus or stomach. In addition, other pathological changes of digestive tissue can also cause hematemesis, such as cirrhosis.

3, pharynx

Different from the above two, if the throat bleeds, it may cough up or spit it out, and the form is not single. There are many reasons for pharyngeal bleeding, such as foreign body injury such as fishbone, and various nasopharyngeal inflammations.

Dry air or just getting up is more likely to bring phlegm and blood.

Pharyngeal congestion is a common phenomenon of chronic pharyngitis, which is a chronic inflammation of pharyngeal mucosa, submucosa and its lymphatic tissue, and is often a part of upper respiratory tract inflammation. It can change from acute pharyngitis to chronic, and chronic inflammatory stimulation of upper respiratory tract, such as chronic sinusitis, nasopharynx inflammation, chronic tonsillitis, long-term oral breathing, excessive smoking and drinking, dust stimulation, excessive use of sound, etc. can all lead to it. The pharynx may have uncomfortable foreign body sensation, burning sensation, itching sensation, irritation and slight pain. Due to the stimulation of viscous secretions from the posterior pharyngeal wall, irritating cough will occur, and when it is serious, it will be disgusting in the morning, and cough often has no secretions.

Most bloodshot phlegm is caused by pharyngolaryngitis, which leads to congestion of pharyngeal mucosa, gradual expansion of blood vessels and stronger permeability of blood vessel wall due to inflammation; Coupled with the severe cough caused by pharyngitis, it is easy to cause capillary rupture and bloodshot sputum. Besides, there will be blood clots. When the air is dry or you just get up in the morning, the symptoms of throat phlegm congestion are more obvious, but the blood volume is generally less. If there is a lot of blood in the sputum, it is necessary to consider whether it is other inflammation or nasal diseases.

There are many possible causes of pharyngeal bleeding. Foreign bodies such as fishbone and jujube pit can also scratch the throat mucosa and cause bleeding. Of course, tumors and blood diseases in the throat can also cause bleeding in the throat.

Treatment mainly lies in removing harmful factors, preventing acute attack and improving symptoms. The former can avoid the stimulation of alcohol and tobacco, improve the working and living environment, treat systemic diseases and enhance resistance, while the latter can use some drugs to relieve symptoms first. At present, there is no clear evidence that there is a clear relationship between chronic pharyngitis and tumor, so don't worry too much.
