How can I prevent gastrointestinal bleeding? How is gastrointestinal bleeding caused?

The common symptoms of gastrointestinal bleeding are hematemesis and melena, and if the bleeding is rapid, the patient will also experience dizziness, palpitations, sweating and even syncope shock. Patients with the above symptoms should first go to the hospital in time to determine whether it is upper gastrointestinal bleeding, and need to fast and fast, and if necessary, do gastroscopy to determine the cause of bleeding.

The main causes of gastrointestinal bleeding include the following:

1. The emergence of peptic ulcer disease is a common cause of gastrointestinal bleeding, such as esophageal ulcer, gastric ulcer and duodenal ulcer, etc., the occurrence of these ulcer diseases will cause damage to the mucosa of our digestive tract, resulting in bleeding, more than 50% of patients with gastrointestinal bleeding are sick because of this **.

2. The onset of gastrointestinal bleeding may also be caused by the coagulation function disorder in our body, mesenteric embolism, disseminated metastasis of intra-abdominal tumors, hemophilia, severe liver disease and vitamin K deficiency, etc., the occurrence of these diseases will lead to the lack of coagulation factors in our body, resulting in coagulation dysfunction, thereby promoting the production of gastrointestinal bleeding.

3. Mechanical injury is one of the main causes of gastrointestinal bleeding. The invasion of foreign bodies and gastrointestinal endoscopy may cause direct damage to the mucosa of our digestive tract, resulting in the condition of bleeding in the digestive tract and the onset of gastrointestinal bleeding.

4. The application of drugs may also make us suffer from gastrointestinal bleeding and infringement, although drugs are substances that help us to suffer from diseases, but some drugs may cause damage to our digestive tract mucosa for a month, and even lead to abnormal coagulation function in our body, which is naturally easy to cause gastrointestinal bleeding.

The digestive tract is divided into upper and lower digestive tracts, and is divided into upper and lower digestive tracts with the duodenum as the boundary. Bleeding in any part of the digestive tract is called gastrointestinal bleeding. However, the amount of gastrointestinal bleeding varies depending on the amount of collateral, and its clinical manifestations vary.

If the amount of bleeding is small, at 5-10ml, the obvious collapse of the bleeding is not visible to the naked eye, but it can be seen under the microscope, and the fecal occult blood is positive; If the amount of bleeding is 50-100ml, the stool may be tarry; If the amount of bleeding is around 250-300, there is often hematemesis; If the amount of bleeding exceeds 1000ml, shock may occur, and circulatory failure such as palpitation, dizziness, and cold sweat may occur. There are many causes of gastrointestinal bleeding, but the common ones are bleeding peptic ulcers, bleeding from esophageal and gastric varices, some mucosal lesions of the colon, and drinking a lot of alcohol at one time can also cause acute upper gastrointestinal bleeding. Some patients have insignificant bleeding symptoms, may only have some abdominal discomfort or may only have abnormal stool, but the stool examination is routine and shows positive occult blood, in this case several more occult blood tests should be checked, if all are positive, further examination should be carried out, do not ignore.

Gastrointestinal bleeding may be due to prolonged heavy alcohol consumption or eating fatty foods. It may also be caused by physical diseases, such as leukemia, liver disease, or vascular disease, which may cause the patient to have digestive bleeding.

There are many causes of gastrointestinal bleeding, the more common ones are Xiaochang Jinhua ulcer, esophageal and gastric variceal bleeding, gastrointestinal tumor bleeding, hemorrhoids, inflammatory bowel disease, vascular resistance to base malformation, etc.

1. Acute gastric mucosal lesions, esophageal and gastric fundus vein rupture and bleeding, surface rupture and bleeding of esophageal tumors in patients with gastric or brightening, and upper gastrointestinal bleeding caused by esophageal cardia laceration; 2. Lower gastrointestinal bleeding caused by colon polyp nucleus, colon tumor, ulcerative colitis, Crohn's disease, etc.; 3. Vascular malformations and small intestine tumors lead to cavity and blood in the middle gastrointestinal tract.

How is gastrointestinal bleeding caused? On the one hand, the quiet defeat is due to improper diet, on the other hand, it is due to the slow rapid formation of physical diseases, Qichang trembling, and the other is an acute external cause.

Yes. This is very good in layman's terms. Each one is different from each other. Compare to those who say. You can consult the answers of professionals. It's okay to ask the people around you. It should be treated in conjunction with daily life.

There are several causes of gastrointestinal bleeding:

1. Vascular lesions: common vascular lesions such as small aneurysms in the gastric wall, aortic aneurysms, hemangiomas, splenic artery aneurysms, hereditary hemorrhagic telangiectasias and gastric submucosal arteriovenous malformations, etc., can lead to gastrointestinal bleeding.

2. Gastroduodenal diseases: peptic ulcer, acute and chronic gastritis, gastric mucosal prolapse, duodenitis, acute gastric dilation, lymphoma, hemangioma, neurofibroma, leiomyoma and other gastroduodenal diseases can also lead to gastrointestinal bleeding.

3. Esophageal lesions: such as esophageal ulcers, chemical or mechanical damage to the esophagus, esophageal cancer, esophagitis, etc., are also important causes of gastrointestinal bleeding.

4. Hepatobiliary and pancreatic diseases: common such as liver cirrhosis with portal hypertension, portal vein thrombosis, ampullary cancer, acute pancreatitis, liver cancer with portal hypertension, biliary tract bleeding, pancreatic cancer invasion of the duodenum, etc.

5. Systemic diseases: epidemic hemorrhagic fever, emphysema combined with infection, cor pulmonale, hemophilia, leukemia, uremia, amyloidosis, lymphoma, purpura, coagulation mechanism disorders, sarcoidosis, etc., these diseases can also cause gastrointestinal bleeding in patients.
