What causes children to vomit blood?

Children's vomiting blood may be caused by gastric mucosal damage, bronchitis, or pneumonia.

1. Gastric mucosal damage: Gastric mucosal damage usually causes children to experience stomach burning, acid reflux and pain, and is accompanied by nausea and vomiting, as well as blood in the vomitus or vomiting blood.

Most of them are caused by various reasons such as eating too much irritating food or gastritis.

2. Tracheitis: Inflammation of the trachea usually causes edema and bleeding of the mucosa, which can cause children to cough and expectorate. Severe coughing may cause rupture of the tracheal mucosa and cause vomiting and bleeding. Most of them are caused by infection with Staphylococcus aureus or epidemic viruses.

3. Pneumonia: It can easily cause children to have severe chest tightness, shortness of breath, cough and sputum, and may be accompanied by chest pain. In severe cases, pneumonia may cause damage to the lung mucosa and cause damage to the bed, which may cause coughing, vomiting, and vomiting blood. It is usually caused by environmental factors or bacterial infection.

It is necessary to go to the hospital in time to complete relevant examinations such as gastroscopy and lung CT to determine the cause of the disease, and use corresponding medications or treatment plans under the guidance of a doctor to prevent serious consequences such as excessive blood loss. At the same time, it is necessary to maintain a light liquid diet to reduce the burden on the digestive system.
