What are the clinical manifestations of gastrointestinal bleeding?

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.

1.Hematemesis with melena.

Characteristic of upper GI bleeding. Heavy bleeding in the upper gastrointestinal tract is followed by melena stool. Patients with bleeding sites above the pylorus are often accompanied by hematemesis.

hematemesis, mostly brown and coffee-ground-like; If the bleeding is heavy and vomits without adequate mixing with stomach acid, it is bright red or has a blood clot. Black feces are tarry, thick and shiny. High intestinal bleeding or even bleeding in the right colon, which can be tarry if the blood stays in the intestinal lumen for a long time.

2.Hemorrhagic peripheral circulatory failure.

Acute massive blood loss leads to peripheral circulatory collapse due to rapid decrease in circulating blood volume. Symptoms include dizziness, palpitation, fatigue, fainting when standing up suddenly, cold sensation in the limbs, increased heart rate, low blood pressure, etc. In severe cases, it is in a state of shock.

3.Anemia and haemogram changes.

Acute massive bleeding is followed by hemorrhagic anemia, but there may be no significant changes in hemoglobin concentration, red blood cell count, and hematocrit in the early stages of hemorrhage.

Patients with acute hemorrhage have normocytic normochromic anemia, and the bone marrow has obvious compensatory hyperplasia after hemorrhage, and macrocytic anemia can temporarily appear, and chronic blood loss presents as microcytic hypochromic anemia. Reticulocytes increase within 24 hours of bleeding and gradually decrease to normal when bleeding stops.

4.Fever. After massive bleeding from the digestive tract, some patients develop a low-grade fever within 24 hours, which lasts for 3-5 days and then decreases to normal. The cause of fever is unknown, but it may be related to factors such as dysfunction of the thermoregulatory center due to peripheral circulatory collapse.

5.Azotemia.

The digestive products of a large amount of blood protein are absorbed in the intestine, and the concentration of urea nitrogen in the blood can be temporarily increased, which is called enterogenic azotemia.

What are the typical manifestations of gastrointestinal bleeding? The clinical manifestations of gastrointestinal bleeding are hematemesis and melena. When there is a lot of bleeding, the function of the circulatory system is affected, such as an increase in heartbeat and a drop in blood pressure.

Long-term low-dose gastrointestinal bleeding can cause unexplained anemia, which can cause dizziness, pallor, prolonged rapid heart rate, and chronic anemia.

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 clinical manifestations vary depending on the amount of gastrointestinal bleeding.

If the amount of bleeding is small, at 5-10ml, no obvious bleeding is 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 only have abnormal stools, but the stool examination is routine positive for occult blood, in this case the occult blood should be checked several more times, and if it is positive, further examination should be carried out, and should not be ignored.

Upper gastrointestinal bleeding can cause hematemesis and black stool, and the clinical manifestations of gastrointestinal bleeding depend on the nature, location, amount and speed of blood loss of bleeding lesions, a small amount of bleeding may cause nausea, etc., moderate bleeding can cause anemia or progressive anemia, dizziness, weakness, sudden standing up can produce syncope, thirst, cold sensation in the limbs and low blood pressure.

1. The clinical symptoms of the primary disease, because the cause of upper gastrointestinal bleeding is mainly caused by some primary diseases, such as ulcer disease, esophageal cancer or duodenal cancer, acute gastric mucosal injury, esophageal and gastric varices rupture and gastric cancer, etc.

2. Hematemesis and black stool, which is also one of the most obvious symptoms of upper gastrointestinal bleeding, mainly manifested as vomiting immediately after the bleeding, the blood is mainly bright red, but if the blood stays in the stomach for too long, it will vomit again after the action of gastric acid, and its color can form a brown like coffee grounds. In addition, because hemoglobin is affected by intestinal sulfide to form black iron sulfide, most of the stools that patients excrete after suffering from this disease are tarry melena.

3. Systemic symptoms, if the patient's bleeding speed is relatively slow and the amount is relatively small, there will generally be no obvious systemic symptoms, but after the bleeding time is prolonged, the patient will have symptoms of anemia. However, if the patient bleeds more heavily and rapidly, symptoms of acute blood loss such as palpitation, cold sweats, pallor, and a drop in blood pressure may occur.

Gastrointestinal bleeding is often characterized by blood in the stool.

First of all, when suffering from the disease of upper gastrointestinal bleeding, the patient will have symptoms of hematemesis, melena and hematochezia after the occurrence of the disease, which are also some of the most common symptoms of upper gastrointestinal bleeding.

Secondly, the patient will have anemia, when the amount of bleeding reaches the medium, there will be anemia or progressive anemia symptoms, this symptom is mainly manifested as dizziness and weakness, and when suddenly standing up, there will often be syncope, thirst, cold sensation in the limbs and low blood pressure and other symptoms, and when the amount of bleeding gradually increases, there will be shock, irritability and confusion symptoms at this time, if this time is not properly handled it is easy to lead to the death of the patient.

Patients will also have symptoms of hemorrhagic peripheral circulatory failure, because patients with upper gastrointestinal bleeding have a relatively large amount of blood loss after the onset of the disease, and the speed of bleeding is also relatively rapid, therefore, if not stopped in time, peripheral circulatory failure will occur, so that patients will have dizziness, fatigue, palpitations, nausea and other symptoms, and patients must pay attention to these symptoms after appearing.

The above is the introduction of the symptoms of upper gastrointestinal bleeding, I believe that after you understand the symptoms of upper gastrointestinal bleeding, you also have a new understanding of the symptoms of upper gastrointestinal bleeding, suffering from upper gastrointestinal bleeding will have a certain impact on the patient's life, if you find some symptoms of upper gastrointestinal bleeding, you should go to the hospital in time to do a good job of examination, to avoid misdiagnosis and mistreatment.

The main clinical symptoms of upper gastrointestinal bleeding are hematemesis and melena.

Upper gastrointestinal bleeding refers to bleeding from the esophagus, stomach and duodenum, and the more common causes of upper gastrointestinal bleeding include gastric ulcer, duodenal ulcer, acute hemorrhagic gastritis, liver cirrhosis, esophageal and gastric varices, and gastric cancer. In addition, stromal tumors of the stomach and lymphoma of the stomach can cause bleeding, and tears in the cardia mucosa due to severe vomiting can also bleed. Symptoms of upper gastrointestinal bleeding include:

1. Hematemesis, hematemesis can occur when there is a large amount of bleeding in the upper gastrointestinal tract, and the vomit is coffee-colored.

1. Hematemesis.

Hematemesis is a very typical clinical symptom of upper gastrointestinal bleeding, when the amount of bleeding below the pylorus is large and the bleeding speed is fast, the blood will reflux into the stomach, which will make the patient nausea, vomiting and hematemesis. On the other hand, if the bleeding site is above the pylorus and the amount of bleeding is relatively small, hematemesis will not occur.

2. Black stool.

When the patient has upper gastrointestinal bleeding, the color of the stool will also turn black, this is because the stool is mixed with blood, and the state of the stool is thick and shiny, if the amount of bleeding is relatively large, the blood will stay in the intestine for a shorter time, so that the stool may become dark red.

3. Anemia. If the condition of upper gastrointestinal bleeding is not controlled for a long time, the bleeding will become more and more serious, and hemorrhagic anemia will slowly appear, which is very damaging to the patient.

4. Peripheral circulatory failure.

If the condition of upper gastrointestinal bleeding is not controlled in time, with the continuous loss of blood, the patient will have dizziness, palpitations, fatigue, cold limbs and other symptoms, and sudden syncope, these conditions are symbols of peripheral circulatory failure, when the disease develops severely, the patient may also have shock.

The clinical manifestations of upper gastrointestinal bleeding depend mainly on the amount and speed of bleeding, and the main manifestations are as follows:

1. Hematemesis and melena, which is the characteristic manifestation of upper gastrointestinal bleeding, there are melena after massive bleeding in the upper gastrointestinal tract, and the bleeding site is often accompanied by hematemesis above the pylorus. If the bleeding is rapid, it manifests as hematemesis. Hematemesis is usually tan or coffee-like.

2. Hemorrhagic peripheral circulatory failure. Acute massive hemorrhage, due to rapid decrease in cardiac volume, leading to cardiofloral failure and possibly death from shock.

3. Anemia and changes in blood count, there is hemorrhagic anemia after acute massive bleeding, hemoglobin concentration, red blood cell base and red blood cell crit can change significantly in the early stage of hemorrhage, and large bleeding in the upper gastrointestinal tract will increase mildly to moderately after two to five hours, and it will return to normal after two to three days of hemostasis.

4. Fever, upper gastrointestinal bleeding, most patients have a low-grade fever within 24 hours, which lasts for three to five days and then decreases to normal.

The most common symptoms of gastrointestinal bleeding are hematemesis and tarry stools, whether the symptoms are obvious or not, and whether the symptoms are obvious are also related to the nature and location of the bleeding lesions, the amount of bleeding, the speed of bleeding and the patient's age, heart and kidney function and other systemic conditions.

The clinical manifestations vary according to the bleeding site, the amount of bleeding, and the speed of bleeding. Small amounts (less than 400ml) and chronic bleeding are mostly asymptomatic without obvious symptoms. Symptoms such as dizziness, palpitation, cold sweat, fatigue, dry mouth, or even syncope, cold limbs, lack of urine, irritability, and shock occur during acute and heavy bleeding.

Gastrointestinal bleeding is a common clinical syndrome that can be caused by a variety of diseases. When there is a small amount of bleeding or chronic bleeding, there are mostly no uncomfortable symptoms;

Symptoms such as dizziness, palpitation, cold sweat, fatigue, dry mouth, and even fainting and shock occur during acute and heavy bleeding. In the event of gastrointestinal bleeding, medical attention should be sought as soon as possible, and **aqui te amo should be performed according to the cause and extent of the bleeding.

Hematemesis and black stool, if there is a lot of bleeding, there will be problems with the circulatory system, low blood pressure, palpitation, long-term small bleeding will cause anemia and dizziness, and upper gastrointestinal bleeding can easily lead to esophageal and gastric varices rupture.

Bleeding from the lower gastrointestinal tract is usually bloody or dark red stool without hematemesis. However, heavy bleeding from the upper GI tract may also manifest as dark red stools; High intestinal bleeding and even the right colon.
