Causes of melena 20, what are the causes of melena

I know that there are many special circumstances in our daily life, and these special circumstances are caused by some habits in our daily life, and we do not pay attention to them. For example, back pain and foot cramps, all these are some physical problems that we often encounter in our lives, and although these problems are not too pathogenic, they will always make people feel dizzy, tired, and weak. For example, there are many reasons for the production of bloody stool in our body, and some of the common causes are as follows.

1. Gastrointestinal bleeding. First of all, the first point is that we will have bloody stools, which may be caused by bleeding from the stomach and digestive tract. The gastric gastrointestinal bleeding may be because of the gastric mucosal epithelium, which is damaged and caused by bleeding perforation, etc., **The damage is relatively light, if the gastric perforation is found, then this matter is undoubtedly very serious, and you should seek medical attention in time.

This kind of pain is very intense, and the pain level can reach about 8 to 9 levels. Therefore, when there is severe pain in the stomach and there is bloody stool, gastric perforation and so on should be considered. <>

2. Gastrointestinal and intestinal bleeding. Secondly, we also have to take into account another point, that is, intestinal bleeding in the digestive tract is also another cause of bloody stool, because the blood of intestinal bleeding is not completely absorbed by the digestive tract, and it will flow to the next rectum and pass the feces through the rectum. This type of bleeding is usually relatively small and dark brown in color because part of the blood has been absorbed by the digestive tract.

3. Bleeding caused by portal hypertension. The last bleeding is also the most severe, and it is often secondary to liver failure or cirrhosis. This portal hypertension is caused by intravascular hypertension caused by the opening of collateral circulation, so that the portal vein cannot circulate blood, resulting in portal vein rupture and bleeding.

This kind of bleeding is more intense every time, and a single bleeding can reach 1000 ml, and this kind of heavy bleeding may cause shock if you are not careful.

Causes of melena: 1. Digestive tract diseases: the most common causes of blood in the stool, including esophageal varices, esophageal foreign bodies, ulcer disease, acute gastritis, gastric mucosal prolapse, intussusception, hemorrhagic necrotizing enteritis, strangulated intestinal obstruction, meke ear asphyxia, intestinal polyps, anal fissures, etc.

2. Blood diseases: neonatal hemorrhage, hemophilia, leukemia, aplastic anemia, thrombocytopenia and Henoch-Schonlein purpura. 3. Other systemic infectious diseases, such as sepsis, typhoid, etc.

4. Influence of food or drugs: Some foods and drugs can also cause changes in the color of stool, which is sometimes easily confused with blood in the stool. For example, eating a lot of watermelon and tomatoes in summer can make the stool color red, anemia children can turn black after taking iron supplements, and the stool color can also turn black after eating animal blood.

Be careful of black stool The normal color of stool is yellow-green or yellow-brown, and if the diet is fresh vegetables or meat products, blood products, or when the patient takes decoction, the color of the stool will be slightly black, which is a normal manifestation. However, if the stool is tarry black and shiny, first of all, exclude dietary factors, such as not eating fresh vegetables, meat products, and blood products for 3 days. Secondly, it is necessary to consider the occurrence of digestive tract lesions, such as gastric ulcers, gastric bleeding, etc., which may also cause a small amount of bleeding in the digestive tract and tarry stools.

Finally, if it is not caused by such conditions, it should be tested as soon as possible. There are many reasons for black stool, and it is recommended to go to the hospital for a check-up to prescribe the right medicine.

Black stool is a symptom of great concern to clinicians, as there are some serious diseases in which melena is the main clinical manifestation. But if black stool does occur, it does not necessarily lead to a malignant serious disease, why is this so? The presence of melena may be gastrointestinal bleeding, which is already very serious.

But it is also possible that there is a false melena, what is a false melena? It is the darkening of the stool due to taking certain foods or drugs, and the first thing to rule out is to rule it out. Including iron or iron-containing supplements when anemia, some traditional Chinese medicines, as well as bismuth preparations in Western medicine, such as bismuth potassium citrate, pectin bismuth and other preparations containing metal bismuth commonly used in Helicobacter pylori, and eating some animal blood, such as pig's liver, which is rich in blood, may make the stool darker, similar to black stool.

How can you tell the difference? First, determine whether these conditions are present from the medical history, and secondly, if in doubt, you should go to the hospital, where the doctor will check for occult blood in the stool. If the fecal occult blood is positive, it means that there is real bleeding in the gastrointestinal tract.

What is common with gastrointestinal bleeding? Mainly common in diseases of the upper gastrointestinal tract, such as erosions of the gastric mucosa, especially gastric or duodenal ulcers, jejunal lesions, which can be inflammatory ulcerative lesions or tumors, can only be determined after gastroscopy**. If there is not only formed black stool, but also more stools, more amounts, or even not just black stools, but similar to asphalt stool, there is an asphalt-like oily, sticky, and bright black stool, accompanied by dizziness, fatigue, etc., it means that the digestive tract has bleeding, and it is a more serious bleeding, and you must go to the hospital in time for examination and **.

Causes of melena:

1. Injury: Chemical injury, such as accidental ingestion of strong acid, strong alkali or other corrosive drugs and heavy drinking, can cause necrosis and bleeding of the esophageal and gastric mucosa; physical injuries such as esophageal foreign bodies or endoscopic injuries, or gastroliths (persimmons); It can cause damage to the esophageal or gastric mucosa and cause bleeding, resulting in melena.

2. Inflammation: stress ulcers: more common in severe trauma; Extensive gastric mucosal erosion and bleeding are often followed by severe infection, cerebrovascular accident, and severe hypoxia.

3. Hypersecretion of gastric acid: if the concentration of gastric acid is too high, pepsinogen will be activated and cause gastric and duodenal ulcers, and active ulcers are easy to cause bleeding; Gastrinomas are caused by the continuous secretion of large amounts of gastrin by the pancreas, which causes excessive gastric acid and causes multiple peptic ulcers and produces melena.

4. Infection: Although tuberculosis and fungal infections are rare, they can indeed cause erosion of the mucosa of the esophagus, stomach and duodenum and hemorrhagic hookworm parasitic in the duodenum, and hookworm is one of the common causes of melena.

5. Drug damage: some drugs can damage the gastric mucosa and cause erosion and ulcers, such as indomethacin, phenylbutazone, aspirin, etc.; Adrenocorticosteroids promote the secretion of gastric acid and pepsin, and may be associated with stress ulcers.

Systemic diseases: such as various blood diseases, hemophilia, uremia, connective tissue diseases, diffuse intravascular coagulation is a kind of coagulation dysfunction caused by a variety of **, sometimes mainly manifested by black.

Some people with ulcer disease have bleeding and are unaware of it. The reason is that when the bleeding is slow and the amount of bleeding is small, the color of the stool is not visible to the naked eye, and the compensatory effect of the body makes the symptoms of blood loss not manifest. It is only when the bleeding is rapid and heavy that the patient may notice a change in the quality of their stool, such as the passage of tarry melena.

When the bleeding is greater and faster, dark red bloody stools may be passed, and even coffee-like vomiting and hematemesis may occur. At the same time, it may also be accompanied by symptoms such as palpitations, dizziness, thirst, cold sweats, syncope, and shock.

About 10% of patients with ulcer disease and bleeding do not usually have the common symptoms of ulcer disease, and there are no obvious signs before bleeding, but the first symptom is sudden heavy bleeding, and the diagnosis of ulcer disease with bleeding is only diagnosed after admission examination. The vast majority of other symptomatic ulcer patients often experience bleeding due to excessive fatigue, poor diet, stress, climate change, and the use of certain medications (such as cold medicines and painkillers). Signs of bleeding include worsening epigastric pain and nausea, but the pain symptoms will be significantly reduced or even completely disappeared after bleeding.

The illusion that these symptoms are getting better is often misleading and the patient is neglected to seek medical attention promptly, resulting in delays in treatment.

Initiatives are proposed. It is recommended that when black stool occurs, the patient should take some measures to flush out the toxins from the body. Drinking a glass of boiled water with salt in the morning is very effective, because salt can promote the peristalsis of the stomach and intestines and help to remove toxins from our body.

The causes of melena are mostly caused by upper gastrointestinal bleeding, food or drugs that cause melena from eating, eating animal offal, etc.

If the blood is bright red, the most common is hemorrhoids, because the hemorrhoids are squeezed too hard when defecation, the blood will stay together, of course, the anal fissure will also be like this, and there may be rectal bleeding, if the anal fissure and hemorrhoids are excluded, you have to go to the hospital.
