What are the manifestations of upper and lower gastrointestinal bleeding?

Go to the central hospital for a check-up, don't think it's a trivial matter, don't be afraid of 10,000.

Symptoms of gastrointestinal bleeding: 1. The typical manifestation of pain is that it will produce pain, and often patients will have more severe colic before or after eating. 2. If the symptoms of gastrointestinal bleeding in patients with hematemesis are more serious, and the bleeding site is located above the digestive tract, it is very likely that the phenomenon of hematemesis will occur, and the amount of hematemesis varies greatly according to the severity of the patient's condition.

3. If the patient's gastrointestinal bleeding site is located below the digestive tract, and the amount of bleeding is relatively small, then black stool will occur. 4. Anemia due to long-term chronic or acute bleeding, so most patients with gastrointestinal bleeding will have the problem of anemia, paleness, weakness and cold hands and feet.

Gastrointestinal bleeding is a common condition. Gastrointestinal bleeding may cause shock and choking in the patient. Therefore, the harm of this disease to the human body is very great.

Depending on the location, we divide gastrointestinal bleeding into upper gastrointestinal bleeding and lower gastrointestinal bleeding. How do we distinguish between upper and lower gastrointestinal bleeding? The following is a brief introduction to the differences between these two diseases.

Upper and lower gastrointestinal bleeding have different locations and causes. Upper gastrointestinal bleeding occurs in organs such as the esophagus, stomach, duodenum, upper jejunum, and pancreatic ducts and bile ducts. The site of lower gastrointestinal bleeding is the intestine below the suspensory ligament of the duodenum.

In general, upper gastrointestinal bleeding is caused by diseases such as ulcer disease, gastritis, and liver disease. In contrast, there is generally no history of lower gastrointestinal bleeding. Lower gastrointestinal bleeding is generally caused by anorectal disorders.

The clinical symptoms of upper gastrointestinal bleeding are also different from those of lower gastrointestinal bleeding. If the patient has hematemesis with blood in the stool, it indicates upper gastrointestinal bleeding. If simple blood in the stool is present, it is lower gastrointestinal bleeding.

Upper GI bleeding may cause melena, tarry stools, and occult blood in the stool. In the lower gastrointestinal tract, there is bright red bloody stool. Upper gastrointestinal bleeding has a large amount of blood in the stool, less stool, and blood is evenly mixed with the stool.

Bleeding from the lower gastrointestinal tract can cause blood to drip during stool. The main symptoms of upper gastrointestinal bleeding are epigastric pain, heartburn, and acid reflux. The main symptoms of lower gastrointestinal bleeding are lower abdominal pain, periumbilical pain, and blood in the stool.

The above is the difference between upper and lower gastrointestinal bleeding. I believe that through the author's introduction, everyone should have a good distinction between these two types of gastrointestinal bleeding. Upper and lower gastrointestinal bleeding are serious gastrointestinal disorders.

If gastrointestinal bleeding occurs, the patient should first make a self-judgment. It must be diagnosed clearly before it can be carried out**. Otherwise, it will not only be effective, but may also worsen the condition.

Hello, common causes are gastroduodenal ulcers, esophageal diseases, and esophageal and gastric variceal bleeding caused by portal hypertension.

There are many cases of upper gastrointestinal bleeding, the most common of which is peptic ulcer, and other common cases include esophageal and gastric variceal rupture, acute erosive hemorrhagic gastritis and gastric cancer.

Main**. The most common cause of this disease is peptic ulcer, which can easily cause upper gastrointestinal bleeding when the ulcer in the upper part of the stomach and small intestine is too deep or too large; In addition to this, when present.

High-risk population.

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.

Upper gastrointestinal bleeding is manifested by abdominal pain, diarrhea, nausea, vomiting, etc., and severe bleeding will cause dizziness, palpitation, fatigue, and even syncope.

Bloody stools, which can be seen in the presence of bright red or dark red bloody stools when there is heavy bleeding in the upper gastrointestinal tract. There are no systemic symptoms when the amount of bleeding is small, but dizziness, palpitation, blood pressure drop and even shock can occur when there is heavy bleeding.

First of all, the most common manifestation is hematemesis and/or melena, which is a sign of upper gastrointestinal bleeding, and the bleeding site is above the pylorus, often with hematemesis and melena. Below the pylorus can only manifest as melena, the color nature of hememesis and melena is also related to the amount and speed of bleeding, hematemesis into bright red and blood clots indicate that the amount of bleeding is large and fast, the blood god head stays in the stomach for a short time, and vomits without full mixing of gastric acid, if the vomited blood is brown coffee grounds, it indicates that the blood stays in the stomach for a long time, and is caused by the formation of euheme by gastric acid, and the tarry black stool is caused by the iron in hemoglobin and the sulfide in the intestine to form iron sulfide, When the amount of bleeding is large and fast, the blood advances quickly in the intestine, and the stool can be dark red or even bright red, which needs to be distinguished from lower gastrointestinal bleeding, on the contrary, jejunoileal bleeding, if the amount of bleeding is not large and stays in the intestine for a long time, it can also be manifested as black stool, which needs to be distinguished from upper gastrointestinal bleeding.

The main clinical manifestation of lower GI bleeding is hematochezia. If the amount of bleeding is small, it is only a positive fecal occult blood test, and if the amount of bleeding is large, in addition to the clinical manifestations of blood in the stool, there can also be symptoms such as low blood pressure, fatigue, dizziness, paleness, and rapid heartbeat.

Causes of upper gastrointestinal bleeding

Usually some people say that there will be gastrointestinal bleeding, but some people think that this is only temporary, and there is no big problem, but some people feel that it is a little uncomfortable, so they think about what method to use to improve it. But some people usually have upper gastrointestinal bleeding, they will think it's nothing, and generally some people will think it's normal, so they won't care much and rarely pay attention to it, but some people will be more worried, if they are afraid of causing other problems for a long time, but they don't know what the cause is, so what are the causes of upper gastrointestinal bleeding? Let's take a look.

Causes of upper gastrointestinal bleeding

1. Inflammation. If there is upper gastrointestinal bleeding, it is usually a congested, erosive ulcer caused by inflammation of the mucosa of the gastrointestinal tract. Moreover, there are many people who have bleeding due to gastric ulcers, such as acute gastric mucosal lesions, tuberculosis, hookworm infection, etc., which can cause upper gastrointestinal bleeding.

2. Machinery. Generally, gastric and jejunal diverticulum, and infection cause mucosal erosion and bleeding, if the mucosal abrasion, obstruction, and sometimes wear caused by hiatal hernia, it will also cause bleeding; Sometimes, violent vomiting will increase the pressure in the stomach, which will cause the mucosa at the junction of the esophagus and stomach to tear and bleed.

3. Blood vessels. Upper gastrointestinal bleeding can sometimes be caused by esophageal varices due to cirrhosis, hereditary telangiectasia, gastric fundic artery malformation, etc., which can cause bleeding, so you should pay more attention to it.

Suggestion: Hello, the symptoms of upper gastrointestinal bleeding are:

1.hematemesis and/or melena;

2.The amount of bleeding within 400ml can be asymptomatic, the amount of bleeding is moderate can cause anemia or progressive anemia, dizziness and weakness, sudden standing up can produce syncope, thirst, limb cold sensation and low blood pressure. Massive bleeding up to 30 50 (about 1500 2500ml) can produce shock, which is manifested as irritability or confusion, paleness, clammy limbs, cyanosis of the lips, dyspnea, undetectable drop in blood pressure, narrowing of pulse pressure difference (less than and fast and weak pulse rate (pulse rate greater than 120 minutes), etc., if not properly treated, it can lead to death;

3.azotemia;

4.Cases of moderate or heavy bleeding, fever within 24 hours, mostly below 38.5 degrees, lasting from a few days to a week;

5.Signs: weight loss.

Left supraclavicular fovea lymphadenopathy and epigastric mass are more common in gastric cancer; Spider angiomata, splenomegaly, and ascites are more common in portal hypertension, gastric fundus, esophageal varices rupture; jaundice, gallbladder enlargement, severe epigastric pain, and hematemesis in the form of strips suggests extrahepatic biliary hemorrhage; **Mucosal hemorrhage suggests systemic disease, such as telangiectasia and capillary hemangioma of the mucosa, especially the face, upper limbs**, and mucous membranes of the mouth and nasopharynx, which are seen in hereditary hemorrhagic telangiectasia.

Symptoms of gastrointestinal bleeding 1. Hematemesis: The blood of hematemesis is bright red or blood clots, indicating that the amount of bleeding in the digestive tract is large and fast, and the vomited blood is dark red, which means that the blood stays in the stomach for a long time. 2. Black stool: due to bleeding in the digestive tract, blood will enter the intestines.

Hematemesis and/or melena are characteristic findings of upper GI bleeding.

HematemesisGenerally speaking, bleeding above the gastric pylorus leads to hematemesis, and when the bleeding is large and fast, the blood stays in the stomach for a short time, and the vomited blood is mostly bright red. Blood accumulates in the stomach for a long time, and under the action of gastric acid, it mostly turns into a brown coffee-like color.

Bleeding below the pylorus often leads to hematochezia, blood stays in the intestine for a long time, and the hemoglobin in the blood and sulfide in the intestine form iron sulfide under the action of bacteria, which is mainly manifested as melena, also known as tarry stool. Patients with heavy and rapid upper gastrointestinal bleeding may also have bloody stools due to rapid intestinal peristalsis. After hematemesis, there is often melena, and melena does not necessarily have hematemesis.

Upper gastrointestinal bleeding refers to bleeding from the esophagus, stomach, duodenum, upper jejunum, pancreatic duct and biliary tract, and is a common clinical emergency in internal medicine. Common causes of upper gastrointestinal bleeding are peptic ulcer, acute and chronic gastritis, liver cirrhosis with ruptured esophageal or gastric varices, gastric cancer, stress ulcers, etc. The main symptoms of the disease are hematemesis and melena, which may be accompanied by it.

1. Hematemesis: The blood of hematemesis is bright red or clots, indicating that the amount of bleeding in the digestive tract is large and fast, and the vomited blood is dark red, which indicates that the blood stays in the stomach for a long time. 2. Black stool: due to bleeding in the digestive tract.

Upper gastrointestinal bleeding refers to bleeding from the esophagus, stomach, and duodenum, and the more common causes of upper gastrointestinal bleeding include gastric ulcers, duodenal ulcers, acute hemorrhagic gastritis, and cirrhosis of the liver, esophageal and gastric varices.
