What are the serious symptoms of intestinal bleeding

Intestinal bleeding is particularly harmful to physical health, and mainly refers to bleeding in some parts of the digestive tract, including the duodenum. Because the symptoms of bleeding can cause anemia in patients, leading to fainting, and even vomiting blood or black stools. More serious patients may develop some lymphatic lesions. If intestinal bleeding occurs, it is necessary to check the cause in time and then treat it symptomatically.

1. Anemia, syncope:

Bleeding within 400 ml may be asymptomatic, while moderate bleeding may cause anemia or progressive anemia, dizziness, weakness, syncope, thirst, cold limbs and low blood pressure when standing up suddenly. Massive bleeding reaching 30-50% of the total blood volume (about 1500-2500ml) can cause shock, which is manifested by restlessness or confusion, pale complexion, cold and wet limbs, cyanosis of lips, difficulty breathing, blood pressure drops to undetectable, pulse pressure difference decreases (less than 3.33-4kpa) and pulse is fast and weak (pulse rate is greater than 120 times/minute), etc. If not properly handled, it can lead to death;

2. Vomiting blood and/or black stool:

Patients with bleeding above the pylorus often experience vomiting blood and black stools, while patients with bleeding below the pylorus may only experience black stools. However, lesions above the pylorus with a small amount of bleeding and a slow bleeding rate may only cause black stools, while lesions below the pylorus with a large amount of bleeding and a fast bleeding rate may cause vomiting of blood due to the reflux of blood into the stomach.

3. Azotemia:

Massive bleeding up to 30-50% of the total blood volume (about 1500-2500ml) can cause shock, which is manifested as irritability or confusion, pale complexion, cold and wet limbs, cyanosis of lips, difficulty breathing, blood pressure drops to undetectable, pulse pressure difference decreases (less than 3.33-4kpa) and pulse is fast and weak (pulse rate greater than 120 beats/minute), etc. If not properly handled, it can lead to death;

4. Lymphatic lesions:

Weight loss, left supraclavicular lymphadenopathy, and upper abdominal mass are common in patients with gastric cancer; spider nevi, splenomegaly, and ascites are common in patients with portal hypertension and ruptured esophageal varices at the gastric fundus; jaundice, gallbladder enlargement, severe upper abdominal pain, and vomiting blood in the form of strips indicate extrahepatic biliary bleeding; bleeding in the skin and mucous membranes indicates systemic diseases, such as telangiectasia and capillary hemangiomas in the skin and mucous membranes, especially on the face, upper limbs, and oral and nasopharyngeal mucosa, which are seen in hereditary hemorrhagic telangiectasia;
