What are the symptoms of lower 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: 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:

Because there is bleeding in the digestive tract, the blood will enter the intestines and react with the digestive juices, so as long as there is bleeding in the digestive tract, then there will definitely be black stool. During upper gastrointestinal bleeding, the patient's stool is tarry, sticky, black and shiny. However, when there is bleeding in the lower gastrointestinal tract, the stool appears dark red or bright red.

3. Fever: After heavy bleeding, most people will have symptoms of fever within a day. But the fever does not exceed.

The duration will be three to five days. 4. Azotaemia: due to gastrointestinal bleeding, the intestines will absorb the protein in the blood, causing the concentration of urea nitrogen in the blood to rise.

If urea nitrogen continues to rise, it may lead to kidney failure. 5. Hemorrhagic peripheral circulatory failure: when the amount of upper gastrointestinal bleeding is large, a large amount of blood is missing, and the circulating blood volume is reduced.

The amount of blood returning to the heart decreases, and the amount of blood pumped by the heart decreases, and there will be acute peripheral circulatory failure, which depends on the size of the bleeding and the speed of bleeding. Patients often experience dizziness, palpitations, fatigue, sweating, thirst and even fainting. In severe cases, shock occurs, and in the early stages of shock, the patient feels thirsty, and the patient's vital signs have a rapid but weakened pulse.

In shock, the patient's complexion will be pale, the lips will be blue-purple, the breathing rate will be rapid, the temperature will drop, the sweating will be more, and the color will be grayish-white. Azotemia: As a result of gastrointestinal bleeding, the intestines absorb proteins from the blood, causing the concentration of urea nitrogen in the blood to rise.

If urea nitrogen continues to rise, it may lead to kidney failure.

Hello, dear, the symptoms of gastrointestinal bleeding are: hematemesis, hematochezia or melena, shock, fever, anemia. If you feel unwell, we recommend that you go to the hospital.

Gastrointestinal bleeding may result in blood in the stool, vomiting, stomach pain, and paleness.

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.

Symptoms of gastrointestinal bleeding depend on the amount of bleeding, the rate of bleeding, the location of bleeding, and are related to age and compensatory circulatory function

1. Hematemesis and melena: Upper gastrointestinal bleeding has melena, and the bleeding site is above the pylorus, often accompanied by hematemesis; The amount of bleeding is small, the speed is slow, there is no hematemesis, only melena; Hematemesis is brown or brown in color, and if the bleeding is heavy, it is bright red when it is well mixed with gastric juice; Black stools are tarry, sticky and shiny;

2. Bloody stool or dark red stool: mostly caused by bleeding in the middle and lower gastrointestinal tract, generally without hematemesis;

3. Hemorrhagic peripheral circulatory failure: patients with acute massive bleeding may experience dizziness, palpitation, fatigue, fainting when standing up suddenly, chills in the limbs, rapid heart rate, low blood pressure, etc., and in severe cases, they are in a state of shock;

4. Anemia and blood changes: hemorrhagic anemia will occur when acute massive bleeding, and mild anemia or no anemia is common in clinical practice;

5. Fever: Some patients may have low-grade fever within 24 hours, which lasts for 3-5 days and decreases to normal, which may be related to the dysfunction of the thermoregulatory center caused by peripheral circulatory failure;

6. Azomi: Urea nitrogen elevated in renal function.

Gastrointestinal bleeding is an acute and critical disease in gastroenterology, and the bleeding above the ligament is called upper gastrointestinal bleeding, and the bleeding caused by the disease below the ligament is called lower gastrointestinal bleeding. Common diseases that cause upper gastrointestinal bleeding include acute erosive hemorrhagic gastritis, peptic ulcer disease, esophageal cardia mucosal tear, esophageal and gastric varices, esophagogastric tumors, etc., and patients have clinical symptoms such as hematemesis and melena. Common diseases that cause lower gastrointestinal bleeding include inflammatory bowel disease, ischemic bowel disease, colorectal and small bowel tumors, vascular malformations, diverticulitis, etc.

Patients with lower gastrointestinal bleeding may have symptoms such as dark red or even bright red bloody stools. Patients with gastrointestinal bleeding can have symptoms of anemia and blood loss such as dizziness, palpitation, fatigue, sweating, etc., and when the amount of bleeding reaches about 1000ml, symptoms of hemorrhagic shock such as blackout, syncope, and loss of consciousness can also occur.

Gastrointestinal bleeding is a common clinical syndrome, which can be caused by a variety of diseases, such as small bleeding (less than 400ml), chronic bleeding without obvious symptoms, dizziness, palpitation, cold sweat, fatigue, dry mouth and other symptoms during acute and heavy bleeding, and even syncope, cold limbs, lack of urine, irritability, shock and other symptoms.

The most common symptoms of gastrointestinal bleeding are hematemesis and blood in the stool. In addition, after bleeding, if the patient is accompanied by circulatory disorders, especially when there is some heavy bleeding, there will be palpitation, chest tightness, blood pressure drop, cold sweat, rapid heartbeat and other manifestations of circulatory disorders.

Gastrointestinal bleeding is often chronic 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 includes upper gastrointestinal bleeding and lower gastrointestinal bleeding, where symptoms of upper gastrointestinal bleeding include malignancy, vomiting and blackening of the stool, fresh blood or coffee-like blood in the vomit, and black, tarry in the stool; The main manifestation of lower gastrointestinal bleeding is blood in the stool, which is bright red or dark red.

Symptoms of gastrointestinal bleeding, many parents do encounter this problem in the clinic will be very confused. Gastrointestinal bleeding is divided into upper gastrointestinal bleeding and lower gastrointestinal bleeding. When upper gastrointestinal bleeding occurs, blood accumulates in the stomach, which can cause symptoms of stomach discomfort in the child, many of which are manifested as nausea and vomiting, and in severe cases, there may be coffee-like or even blood-like substances in the vomit, which must have upper gastrointestinal bleeding.

The clinical manifestations of gastrointestinal bleeding depend on the volume of blood, the rate of bleeding, the location and nature of bleeding, and the patient's age and ability to compensate circulatory function. When the symptoms are mild, there may be no manifestations, and when the bleeding is obvious, hematemesis, melena, and hematochezia may be seen. Continued exacerbations may be accompanied by anemia, hypovolemia, and even shock.

Some patients may experience dizziness and fatigue in gastrointestinal bleeding, which can be compensated by tissue fluid and spleen blood storage, and the circulating blood volume can be improved within 1 hour, so there may be no conscious symptoms. When symptoms such as dizziness, palpitation, cold sweats, fatigue, and dry mouth appear.

Gastrointestinal bleeding depends on the location of the bleeding. When the clinical manifestations are mild, there may be no symptoms, but in severe cases, there will be vomiting blood, hematochezia, black blood in the stool, and then anemia.

Hematemesis and melena.

Characteristic of upper GI bleeding. Hematemesis and melena are common in patients with bleeding sites above the pylorus, and melena may appear only in patients below the pylorus. However, melena may be seen only in high-volume and slow-bleeding suprapyloric lesions, while high-volume, high-speed lesions below the pyloric may cause hematemesis due to blood reflux into the stomach.

Symptoms of lower gastrointestinal bleeding. Lower gastrointestinal bleeding refers to some bleeding caused by the system below the duodenum, and its clinical symptoms are mainly bloody stools, which can be black stools, red bloody stools, or dark red stools, and can not be accompanied by hematemesis.

However, if the bleeding site is high, the plasma will stay in the intestinal lumen for a long time and will be slightly blackened, most of them are dark red or bright red, and others will also appear chills, dizziness, and some will have low blood pressure, cold sweat, palpitation, some have a fast pulse, if it is severe, there may be shock, shortness of breath These symptoms, some will be accompanied by fever, as well as nausea and vomiting, and the main symptoms are these.

Patients with lower GI bleeding often present with bright red or dark red bloody stools. Bleeding from right colon lesions is often dark red, and bleeding from left colon and rectal lesions is bright red.

There's no need to dream all the time, keep dreaming unrealistically, it's better to go to work and make money quickly to realize your dream.

Upper gastrointestinal bleeding is mainly hematemesis, and lower gastrointestinal bleeding is mainly hematochezia. Upper gastrointestinal bleeding is mainly caused by esophageal gastric lesions, lesions in the upper duodenum, such as ulcers and tumors, and lower gastrointestinal tract mainly caused by lesions of the large and small intestines or hemorrhoids.

Patients with gastrointestinal bleeding may have black stools and blood in the bowel movements, depending on the location of the bleeding and the amount and speed of the bleeding. Rapid bleeding will manifest as bloody stools, which are dark and bloody stools. In chronic blood loss, blood and intestinal contents are mixed to produce tarry stools that can also adhere to the surface of the stool.

In addition, intestinal edema can also manifest as loose stools or mucus, pus and bloody stools, and lower gastrointestinal bleeding is the most common disease caused by malignant tumors, and patients will also present with symptoms of loose stools or constipation. If it is due to a neoplastic cause, further testing and ** are required.

Blood in the stool: the main symptom of acute lower GI bleeding, blood in the stool may appear bright red or dark red, sometimes tarry; Abdominal pain: Abdominal pain can vary depending on the cause of bleeding; Accompanied by vomiting, diarrhoea, tenesmus.

You should go to the local clinic immediately to check the situation to avoid serious circumstances and bad effects.

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.
