Coughing when lying down and sitting up may be seen for a variety of reasons, commonly such as respiratory infections, reflux esophagitis, cardiac lesions and so on.
1. Respiratory infections: This phenomenon may also be caused by respiratory infections. When you lie down to rest, the bronchial tubes will be in a horizontal state, which will cause pressure on the surrounding lung tissues, and then the bronchial tubes will become relatively narrow, and coughing symptoms will easily appear.
2. Reflux esophagitis: For patients with reflux esophagitis, when lying down, a small amount of stomach content will flow through the esophagus, causing irritation to the throat or trachea, and coughing symptoms may occur. When sitting up, due to the effect of gravity, the contents of the stomach can not flow upward, and the symptoms of coughing will be reduced or disappear.
3. Heart disease: Lying down and coughing while sitting up can be caused by heart disease, such as left heart failure. For patients suffering from this disease, usually cause lung congestion, will produce cardiogenic asthma, coughing symptoms.
Lying down and coughing when sitting up can also be other causes, such as bronchial dilatation, lung tumors, pleural effusion, etc. Patients should go to the hospital in time to see a doctor to clarify the cause of the disease and then under the guidance of the doctor to carry out the appropriate treatment and therapy.
