What is the cause of vomiting blood and pulling blood?

If symptoms of vomiting blood or bleeding occur, the most common cause is gastrointestinal bleeding, such as bleeding caused by rupture of varicose veins at the fundus of the stomach. This situation is quite dangerous and you should go to the hospital for examination in time. You should receive symptomatic hemostatic treatment, prevent complications, actively cooperate with the doctor, and abstain from food and water for a certain period of time. Let’s take a look at this aspect.

What is the cause of vomiting blood and pulling blood?

Gastrointestinal bleeding can be caused by inflammation, mechanical injury, vascular disease, tumors and other factors of the digestive tract itself, or it can be caused by lesions of adjacent organs and systemic diseases involving the digestive tract. 1. Upper gastrointestinal bleeding 2. Middle and lower gastrointestinal bleeding (1) Anal canal diseases: hemorrhoids, anal fissures, and anal fistulas. (2) Rectal diseases: ulcerative proctitis, tumors (polyps), carcinoid, adjacent malignant tumors or abscesses invading the rectum, infections (bacterial, tuberculous, fungal, viral, parasitic), ischemia, etc. (3) Colonic diseases: infection (bacterial, tuberculous, fungal, viral, parasitic), ulcerative colitis, diverticula, tumors (polyps), ischemia and vascular malformations, intussusception, etc. (4) Small intestinal diseases: acute hemorrhagic necrotizing enterocolitis, intestinal tuberculosis, Crohn's disease, diverticulitis or ulcer, intussusception, tumor (polyp), hemangioma, vascular malformation, ischemia, etc.

Clinical manifestations

The clinical manifestations vary depending on the site, amount and rate of bleeding. 1. Generally, the bleeding is small in amount (less than 400 ml) and chronic, with no obvious symptoms. In case of acute and massive bleeding, symptoms such as dizziness, palpitations, cold sweats, fatigue, dry mouth, and even fainting, cold limbs, oliguria, irritability, and shock may occur.

2. Changes in vital signs pulse and blood pressure are important indicators of the extent of blood loss. In acute gastrointestinal bleeding, blood volume decreases sharply, and the initial compensatory function of the body is to increase the heart rate. If the bleeding cannot be stopped or blood volume cannot be replenished in time, a shock state will occur and the pulse will be weak or even unclear. In the early stages of shock, blood pressure may increase compensatorily. As the amount of bleeding increases, blood pressure gradually decreases, and the patient enters a state of hemorrhagic shock. 3 Other accompanying symptoms and signs may be accompanied by other corresponding clinical manifestations depending on the primary disease, such as abdominal pain, fever, intestinal obstruction, hematemesis, bloody stools, tarry stools, abdominal masses, spider nevi, varicose veins of the abdominal wall, jaundice, etc.
