Melena with gastrointestinal bleeding? Does upper GI bleeding always have melena?

1. Hematemesis and melena are the most common symptoms of gastrointestinal bleeding. The bleeding site will be accompanied by hematemesis and melena above the pylorus, only melena will occur below the pylorus, and the amount of bleeding will be small, and the lesions above the pylorus will have melena. Bleeding is heavy and rapid in subpyloric lesions, which can lead to blood reflux into the stomach and cause hematemesis, which is one of the most serious symptoms.

2. There are no obvious symptoms within 400 ml of blood loss, moderate blood loss will cause anemia or progressive anemia, resulting in dizziness and fatigue, fainting sensation when standing up suddenly, and will also cause cold limbs or low blood pressure, massive bleeding, reaching 30% of the body volume 50% will produce shock, causing patients to be irritable and delirious, and improper treatment will lead to death.

3. Gastrointestinal bleeding can also cause lymphatic lesions, at this time, the patient looks thinner, there is lymphadenopathy on the left clavicle, and the epigastric mass is seen in gastric cancer. Ascites or skin enlargement is a rupture of esophageal varices in the gastric fundus, and gallbladder enlargement or hematemesis into cord-like blood clots indicate extrahepatic biliary bleeding. **Mucosal bleeding indicates a systemic disease, including upper extremities** and oral hemangiomas.

In summary, the symptoms of gastrointestinal bleeding are introduced here. The problem of gastrointestinal bleeding should arouse everyone's attention, hematemesis and melena are gastrointestinal bleeding, the most common symptoms, and one of the very serious manifestations, only by mastering these symptoms can we detect the symptoms as soon as possible, take ** as soon as possible, prevent the harm caused by the disease, usually pay attention to life care, drink more water, eat more light vegetables and fruits.

The clinical manifestations of melena caused by the appearance of the digestive tract should be the black color of the intestine caused by the oxidation of the intestinal blood caused by bleeding in the body.

Hello, bleeding blood from the digestive tract into the stomach is sure to have black stools.

Gastrointestinal bleeding and black stools often take about a day to get there. Mellena is mainly formed after blood is digested and absorbed in the gastrointestinal tract, and often manifests as blackened or tarry stools. Theoretically, if the bleeding in the gastrointestinal tract is greater than 5ml, the fecal occult blood is positive, which is not visible to the naked eye, but it can be found in the stool through the examination of the stool.

Analysis: Gastrointestinal bleeding is black stool, and the bleeding site is in the upper gastrointestinal tract. Under normal circumstances, bleeding of about 50 ml in 24 hours can cause obvious melena.

Upper gastrointestinal bleeding is mostly caused by diseases of the duodenum, stomach, and biliary tract. If there is heavy bleeding in a short period of time, the stool will also be dark red.

Suggestions: If there is melena, you should go to the hospital for gastroscopy and hepatobiliary ultrasound examination in time to confirm the diagnosis in time**.

If black stool is found, the occult blood in it is positive, or black stool is indeed found, it is caused by blood, then the diagnosis of gastrointestinal bleeding is confirmed, and time has nothing to do with it.

In addition, patients with general gastrointestinal bleeding and black stool, and some digestive tract symptoms are fatigue, abdominal pain, and even nausea, vomiting, dizziness, low blood pressure, etc., it is recommended that patients with this condition must pay attention to it, and go to the hospital in time to conduct relevant laboratory examinations to clarify whether it is gastrointestinal bleeding, you can go to the hospital to do stool routine plus occult blood examination, as well as blood routine examination, in addition to gastroscopy examination, abdominal CT examination, etc., to understand the patient's condition, in addition, Assess the severity of the condition. If the bleeding is greater than 60ml, it can show melena, which is often bleeding from the upper gastrointestinal tract, and bleeding from the stomach and small intestine is mostly melena, because the blood has to be absorbed through the entire gastrointestinal tract. Bleeding from the lower gastrointestinal tract, large intestine or hemorrhoids is often predominantly bright red or dark red bloody stools.

In **, first of all, the symptoms**, vital signs monitoring and hemostasis, and then do some examinations, CT, gastroscopy or colonoscopy to clarify the bleeding site, and decide whether to operate in the next step.

If you continue to go out for two or three days and the diet is relatively light, there is a high probability that it is gastrointestinal bleeding, if you feel pain and discomfort at present, you should go to the hospital for examination as soon as possible.

1. Gastrointestinal bleeding is generally divided into upper gastrointestinal bleeding and lower gastrointestinal bleeding, generally the color of upper gastrointestinal bleeding is bright red, and the color of lower gastrointestinal bleeding is black, which is to be treated differently, and it is also a sign to determine the location of gastrointestinal bleeding.

2. The change in the color of the stool is not only caused by gastrointestinal bleeding, but also caused by some dark-colored foods that will cause the color of the stool to appear black, such as the spinach we often eat, the color is dark green, if there are people who have eaten spinach, they will also find that the color of the stool is black when they solve the stool.

3. Therefore, if the stool is black, we should not be particularly panicked and afraid, we must distinguish the reason, if it is caused by food, it is a very normal process of body digestion, if there is a patient with digestive tract disease who finds black stool, it should be paid attention to.

Precautions: If there is a black stool, if there is a patient with digestive tract diseases, when choosing **, the matters that need to be paid attention to are that patients with digestive tract diseases must have a soft and easily digestible diet. If you have black stool, you should seek medical attention in time.

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.

For example, taking certain Chinese herbal medicines, activated charcoal, ferrous carbonate, and some ** ulcer drugs such as gastric treatment, bismuth hypocarbonate, bismuth citrate, etc., the stool may be black, but the fecal occult blood test is negative, so bleeding can be ruled out; In addition, after eating too much pig liver and animal blood (such as pig blood, sheep blood, rabbit blood, etc.), the stool can also be dark red, or even tarry, and the fecal occult blood test is also positive or strongly positive. If there is ingestion of pig liver or animal blood before melena stool, it can be distinguished from upper gastrointestinal bleeding by using a negative occult blood test after a restricted diet (usually vegetarian for three days) and the color of the stool returns to normal.

Melena is not necessarily gastrointestinal bleeding, because certain drugs or foods can also cause melena, such as eating animal liver or blood products, such as duck blood, pig blood, etc., which will make the stool black, and receiving colloidal bismuth and ferrous sulfate** will also show melena.

Black stools are not necessarily gastrointestinal bleeding, but there must be a certain reason, except for some foods you eat, which may cause black stools, the rest may be caused by some diseases.

This is not necessarily the case, because sometimes we can also have black stools by eating, such as animal blood. On the second day, black stool will also be pulled out, but sometimes it is bleeding from the digestive system, which can also cause black stool, so you can go to the hospital for a good examination.

It should be said that when there is upper gastrointestinal bleeding, the amount of bleeding exceeds 60ml, and the stool will be black. But black stools don't always mean heavy bleeding from the digestive tract. In particular, it is closely related to diet, and if you eat too much blood clot in your diet, this may also happen to meat food.

There are also medications that may also cause black stools. It is necessary to analyze comprehensively.

Not necessarily, you can rule out the problem of diet first, if there is a recent iron supplement and eat blood products, it is very normal, and the relationship between diet and diet is very probable, upper gastrointestinal bleeding, it is recommended to go to the hospital for examination.

Upper gastrointestinal bleeding melena may heal on its own, but it is related to the cause and severity of the disease. However, if the bleeding and black stool caused by gastrointestinal diseases are less likely to heal on their own, you can go to the gastroenterology department of the hospital for a detailed examination, and then follow the doctor's instructions to take measures to treat the symptoms**.

Individuals will be surprised to suddenly find that their stool is black. Before the doctor answers, he will definitely ask him about his daily life and diet, whether there is any discomfort, the specific characteristics of black stool, etc., and conduct necessary examinations before making a clear diagnosis. Because the black stool that people see can be a normal physiological phenomenon.

Mellena does not necessarily mean that there is bleeding.

It is necessary to clarify the nature of the stool routine, and the intake of certain iron-containing foods can also lead to the production of melena. Such as animal blood, animal offal, spinach, etc., too much consumption will cause melena, and the melena will disappear when the ingestion is stopped. Certain medications can also cause melena, as can iron-containing drugs such as iron and secret agents.

When melena is reversed, an active gastroenterology department and specialist is required. Through gastrointestinal endoscopy and other related examinations, the bleeding site and nature of bleeding should be clarified, and the bleeding should be standardized, so as to avoid the recurrence of symptoms.

Hello, there must be black stool because the blood got into the stomach.

It is worth discussing this issue, generally a person's stool color can determine the internal situation of his body. When the stool is tarry in color, it indicates upper gastrointestinal bleeding, and the white clay color indicates biliary obstruction. The dark red color indicates lower gastrointestinal bleeding.

Therefore, having melena is not a problem of the upper gastrointestinal tract.

Upper gastrointestinal bleeding is a common gastroenterologic condition and is characterized by hematemesis, coffee-like vomiting, and melena. The reason for melena caused by upper gastrointestinal bleeding is that the hemoglobin in the digestive tract contains iron, which is transformed into black ferrous sulfide by the action of intestinal bacteria in the patient's digestive tract, especially in the small intestine, so the patient's stool is black, and most patients can appear as tarry stools.

If the patient has only tarry stools, GI bleeding is around 50 to 100 ml. The amount of bleeding increases further, the rate of bleeding increases, and the patient not only shows melena, but can even have dark red bloody stools. Melanism is a common manifestation of the upper gastrointestinal tract, and patients are advised to have a stool routine and occult blood test to confirm whether the patient is positive for occult blood.

A positive occult blood indicates the presence of gastrointestinal bleeding, at which point the patient's endoscopy can be used to determine the level of upper gastrointestinal bleeding**, and endoscopy if necessary.

There are many cases of heavy bleeding in the upper gastrointestinal tract, and the common ones are peptic ulcer, acute gastric mucosal damage, esophageal and gastric varices, and gastric cancer. Hematemesis or melena is 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, the lesions above the pyloric with little bleeding and slow speed can only see melena, and the stool of patients with upper gastrointestinal bleeding is black and can be seen in the factors of eating blood products and drugs, and it is necessary to check the fecal occult blood for identification, and gastroscopy can identify the bleeding site, which needs to be active**.

It is recommended to go to a regular hospital for examination and treatment as soon as possible.

Analysis: Melania is a common clinical symptom of upper gastrointestinal bleeding. Gastric bleeding is an acute and severe gastrointestinal disease, requiring hospitalization**, the use of omeprazole, thrombin, Yunnan Baiyao, etc., hemostasis, acid suppression, etc.**.

Guidance: It is recommended that you go to the gastroenterology department of the hospital for treatment, system**, during the period of gastric bleeding, you should fast in your diet, but if you are not hospitalized, you must not overeat at home, it is best to drink some rice soup every day, do not eat coarse grains, especially those who are more prickly. Static sites such as omeprazole and pantoprazole can be applied.

Guidance: Most of the upper gastrointestinal bleeding can lead to black stool, and the reason why the stool color becomes black is mainly because the hemoglobin of ferric ions in the blood in the gastrointestinal bleeding becomes ferrous iron of ferric ions, and the color of ferrous iron is mostly black, so the color of stool is black. The main reason is that the amount of bleeding is relatively large, and at the same time, it stays in the intestine for a long time.

If there is gastrointestinal bleeding, the amount of bleeding is relatively large, and the stay time is relatively short, and the ferric ions cannot be turned into ferric ions in a short period of time, and most of the stools are bright red blood, and if they become ferric ions, most of them are dark red or tarry black stools. Therefore, the color of the stool is mainly due to the fact that the ferric ions turn into ferric ions.
