Upper gastrointestinal bleeding results in the vomiting of coffee-colored blood because the combination of fresh blood with stomach acid forms a coffee-colored liquid. If the bleeding volume exceeds 200mL in a short period, coffee-colored vomit may occur. It is necessary to seek prompt medical attention at a regular hospital’s gastroenterology or emergency department. Adequate diagnosis with an electronic gastroscopy is essential to identify the source and location of the bleeding, and active endoscopic treatment should be undertaken. Additionally, it is crucial to actively replenish fluids, correct the loss of body water, and restore blood volume. Treatment should also include the use of proton pump inhibitors and gastric mucosal protectants.

Why does pulmonary heart disease cause upper gastrointestinal bleeding?

Cor pulmonale is a very common type of heart disease in the clinic, mainly caused by various etiologies leading to pulmonary arterial hypertension, which results in right ventricular hypertrophy. Typically, patients with this disease have underlying pulmonary and cardiac lesions, and it mainly causes symptoms of varying degrees, such as fever, cough, expectoration, shortness of breath, chest tightness, and even difficulty breathing. Cor pulmonale is a complex disease, and if not managed properly in clinical practice, it can lead to many complications, especially respiratory failure and heart failure. This can lead to insufficient blood and oxygen supply, causing various degrees of increased pressure in the gastric vessels or vascular spasms due to hypoxia, all of which can cause patients to experience upper gastrointestinal bleeding during severe coughing, or when consuming certain foods.

Why is there black stool with upper gastrointestinal bleeding?

Gastrointestinal bleeding refers to the condition where blood cells turn black after being decomposed by intestinal bacteria, thus clinically presenting as black stools. Therefore, with a small amount of upper gastrointestinal bleeding, it may simply present as black stools. Of course, with a larger amount of bleeding, it can manifest as vomiting blood or bloody stools, and severe cases may accompany symptoms of low blood flow, such as dizziness, fatigue, chest tightness, etc. For patients with upper gastrointestinal bleeding, it is recommended that they visit the gastroenterology department of a local hospital to undergo further examinations including complete blood count, stool tests, and gastroscopy. Gastroscopy can help identify the location and nature of the bleeding, whether it might be peptic ulcers or gastrointestinal tumors, etc. For treatment, medications that regulate acid and protect the stomach or those that stop bleeding and replenish fluids can be considered symptomatically. Of course, if the black stools are suspected to be caused by a tumor, surgical intervention is generally required.

Which department should I go to for upper gastrointestinal bleeding?

The upper gastrointestinal system primarily refers to bleeding from the digestive system above the Treitz ligament. Therefore, if there is acute massive bleeding in the digestive tract, patients may present with symptoms such as vomiting blood and black stools. If the bleeding is significant and blood volume rapidly decreases, it can cause acute peripheral circulatory disorders, and may even be life-threatening. The causes of upper gastrointestinal bleeding include long-standing conditions like peptic ulcers, rupture of esophagogastric varices, acute erosive hemorrhagic gastritis, and stomach cancer, among others. If upper gastrointestinal bleeding occurs, patients should actively seek medical attention at major hospitals' gastroenterology departments, undergo relevant examinations, and receive prompt treatment.

Upper gastrointestinal bleeding examination methods

Upper gastrointestinal bleeding is relatively common in clinical practice. The main diagnostic methods include gastroscopy, barium meal examination of the gastrointestinal tract, and DS imaging of the gastrointestinal tract, among others. If a patient experiences a large amount of bleeding at a rapid pace after upper gastrointestinal bleeding, it can lead to a drop in blood volume and hypovolemic shock, which can be life-threatening. In such cases, it is crucial to seek prompt medical treatment and use hemostatic drugs, and even endoscopic hemostasis or surgical intervention may be necessary to actively save the patient's life.

What medication is used for upper gastrointestinal bleeding?

Upper gastrointestinal massive bleeding is generally a medical emergency with rapid changes that can even be life-threatening. Immediate anti-shock treatment and rapid blood volume replenishment are necessary. When massive gastrointestinal bleeding occurs, the patient should be kept in a recumbent position for rest, ensuring that the airway remains clear to avoid choking during vomiting, and fasting should be maintained during the bleeding period. In clinical practice, medical treatment mainly includes the following points: firstly, actively preparing blood transfusions to replenish blood volume. Secondly, vasopressin can be used for pharmacological hemostasis. Additionally, treatments with somatostatin and octreotide are also options. Hemostasis can also be achieved through endoscopic treatment. If conservative medical treatment is ineffective, surgical treatment may be considered. (Please use medications under the guidance of a doctor.)
