What disease is vomiting blood clots a symptom of

If you have intestinal diseases, many people will vomit blood. Since ordinary people have a natural sensitivity to blood, they are always worried about whether they have a serious illness. In fact, we should observe the characteristics of vomiting blood, and then tell the doctor the detailed symptoms so that the doctor can make a judgment. Of course, if the doctor cannot make a judgment based on the symptoms alone, you can go for a gastrointestinal endoscopy. So, what diseases usually cause vomiting blood clots?

1. Vomiting blood caused by acute gastroenteritis

The main clinical manifestations of acute upper gastrointestinal bleeding are vomiting blood and black stools. Among them, black stools are often judged as upper gastrointestinal bleeding mainly based on the characteristics of bloody stools. Because under normal circumstances, when upper gastrointestinal bleeding occurs, the iron in hemoglobin in the blood combines with sulfide in the intestine to become iron sulfide, and the stool is tarry black. However, if the amount of bleeding is large and the intestinal peristalsis is too fast, dark red or even bright red bloody stools will appear. When the gastric extract after gastric lavage contains fresh blood, it indicates bleeding in the gastrointestinal tract above the stomach, but operational injury to the mucosa due to the gastric tube should be ruled out.

2. Vomiting blood caused by gastric and duodenal diseases

The main clinical manifestations of acute upper gastrointestinal bleeding are vomiting blood and black stools. Among them, black stools are often judged as upper gastrointestinal bleeding mainly based on the characteristics of bloody stools. Because under normal circumstances, when upper gastrointestinal bleeding occurs, the iron in hemoglobin in the blood combines with sulfide in the intestine to become iron sulfide, and the stool is tarry black. However, if the amount of bleeding is large and the intestinal peristalsis is too fast, dark red or even bright red bloody stools will appear. When the gastric extract after gastric lavage contains fresh blood, it indicates bleeding in the gastrointestinal tract above the stomach, but operational injury to the mucosa due to the gastric tube should be ruled out.

3. Vomiting blood caused by rupture of esophageal or gastric varicose veins

Esophagitis is an inflammation of the esophagus, which refers to inflammation caused by edema and congestion of the esophageal mucosa due to irritation or damage to the superficial or deep tissues of the esophageal mucosa. Chemical irritation includes stomach acid, bile, strong liquor, strong acid, strong alkali, drugs, etc.; physical irritation includes hot food, drinks, foreign bodies in the esophagus (fish bones, etc.), long-term placement of nasogastric tubes, etc.

Esophagitis may also be caused by local damage to the esophagus due to chemotherapy or radiotherapy, or by infection with tuberculosis, fungi (Candida) or viruses due to the patient's own decreased resistance. The most common clinical condition is reflux esophagitis caused by gastric acid reflux.
