what does a hemorrhoids look like,Stool bleeding "three primary colors", easily identify what disease!

    Blood in the stool is generally divided into three forms: stool with blood, or all stools with blood, and the color is bright red, dark red or tarry. These three color forms are just like the three primary colors of "red, yellow and blue" in real life. I call them the "three primary colors of stool blood-black, dark, and red".

    Tar (black) is mostly upper gastrointestinal bleeding

    It should appear in the upper digestive tract-near the stomach and duodenum. It is called "tarmac" because it stays in the intestine for a long time after bleeding from the upper gastrointestinal tract or small intestine, red blood cells are destroyed, hemoglobin combines with sulfide in the intestine to form ferrous sulfide, making the stool look black. Sometimes the stool is shiny with mucus, similar to asphalt.

    1. Continuous pain + hematemesis + melena = stomach cancer

    A small number of patients with early gastric cancer have nausea, vomiting or upper gastrointestinal symptoms similar to ulcer disease. Pain and weight loss are the most common clinical symptoms of advanced gastric cancer. Patients often have clear upper gastrointestinal symptoms, such as upper abdominal discomfort, fullness after eating, upper abdominal pain aggravated as the disease progresses, appetite decreased, and fatigue. Patients with advanced gastric cancer often suffer from anemia, weight loss, malnutrition and even cachexia.

    2. Periodic upper abdominal pain + melena = stomach ulcer

    Stomach ulcer is a common digestive tract disease, and upper abdominal pain is its main symptom. The pain is mostly located in the upper abdomen, but can also appear in the upper left abdomen or behind the sternum and xiphoid process. Often presents dull pain, dull pain, swelling pain, burning pain. The pain of gastric ulcer is usually relieved gradually after 1 to 2 hours after a meal, until the above rhythm reappears after the next meal. Some patients may be asymptomatic, or have complications such as bleeding, melena, or gastric perforation as the first symptoms.

    3. Hematemesis + melena = acute erosive gastritis

    Acute erosive gastritis has a rapid onset and may cause sudden upper gastrointestinal bleeding. Manifestations of hematemesis and melena are rare in people who have melena alone. Bleeding is often intermittent. Heavy bleeding can cause syncope or shock, anemia. There will be dull discomfort or tenderness in the upper abdomen when bleeding.

    4. Upper abdominal pain + hunger pain + melena = duodenal ulcer

    It is manifested as pain in the upper abdomen, which can be dull pain, burning pain, swelling pain or severe pain, or it can be manifested as dull pain and discomfort only when hungry. The typical performance is mild or moderate persistent pain under the xiphoid process. Complications such as bleeding, perforation, and pyloric obstruction can occur. If bleeding occurs, it can cause melena.

    Pus and blood in the stool (dark) colorectal tumor or inflammation

    Dark colored stool is pus and blood stool, which refers to both pus and blood in the excreted stool. The blood is thin in appearance and sometimes contains a lot of mucus. Dark colored stools or bloody stools containing mucus are often found in tumors and inflammations in the rectum or colon, such as:

    1. Continuous difficulty in defecation + tenesmus + constipation/diarrhea + dark stool = rectal cancer

    Early rectal cancer is mostly asymptomatic, but with the growth of colorectal cancer, problems such as changes in bowel habits, bloody stools, pus and bloody stools, tenesmus, constipation and diarrhea will occur to a certain extent. In the later stage, rectal cancer will gradually narrow the stool, and in the later stage, there will be defecation obstruction, weight loss and even cachexia.

    2. Jam type + difficult defecation + dark stool = colon cancer

    Divided into left and right colon cancer, patients with colon cancer early manifested as abdominal distension and indigestion, and then changed bowel habits, abdominal pain before defecation, and later appeared mucus or mucus purulent bloody stool. After tumor ulceration, blood loss, and toxin absorption, poisoning symptoms such as anemia, low fever, fatigue, weight loss, and edema often appear.

    3. Pain + tenesmus + diarrhea + vomiting + dark stool = ulcerative colitis

    The initial manifestations of ulcerative colitis can take many forms. Bloody diarrhea is the most common early symptom. Other symptoms include abdominal pain, blood in the stool, weight loss, tenesmus, and vomiting. Occasionally the main manifestations are arthritis, iridocyclitis, liver dysfunction and skin lesions. Fever is relatively an uncommon symptom. In most patients, the disease is chronic, and in a small number of patients, it presents an acute and catastrophic outbreak. These patients present with frequent bloody stools, up to 30 times a day with high fever and abdominal pain.

    4. Diarrhea + abdominal pain + dark stool = multiple intestinal polyps

    Multiple intestinal polyps are also called familial adenomatous polyposis. Multiple polyps are mostly related to genetics, diet, and inflammatory factors, and their early symptoms are not obvious. Common symptoms include diarrhea, abdominal pain, and blood in the stool. Blood in the stool often persists, accompanied by malignant changes in the later stage. If a secondary infection occurs, the above symptoms will be aggravated, with loose stools, smelly, foamy, and sometimes mucus, pus and blood. There are also constipation associated with tenesmus. In addition, if a large tumor is located at the lower end of the rectum, it can protrude outside the anus after feces, showing a dark red, papillary mass.

    Bloody stools (red) mostly come from the anorectal

    Red stools are bloody stools, and most of the red stools are acute bleeding. The blood flows out of the blood vessels for a short time and then is discharged with the stool through the anus, or flows out directly after the stool. The blood flowing out looks similar to traumatic bleeding, bright red or purplish red, dark red in color, and can coagulate into blood clots after a while. Bloody stools generally come from anorectal diseases, such as:

    1. Splashing/dripping + painless + bright red = hemorrhoids

    Hemorrhoids are the most common disease in anorectal department. Different stages of internal and external hemorrhoids and mixed hemorrhoids can cause fecal bleeding, usually with fresh blood attached to the stool or blood dripping after the stool. In severe cases, splashing blood may appear. It should be noted that external hemorrhoids generally have no stool bleeding.

    2. Painless + blood and feces do not mix + bright red = rectal polyp

    The typical symptom of a low rectal polyp is painless stool bleeding. Bleeding during defecation, stop after defecation, the amount varies, generally blood does not mix with feces. Of course, if the polyps are high and numerous, sometimes the blood will mix with the feces.

    3. Wipe/drip + pain during stool + bright red = anal fissure

    It manifests as pain in the anus during defecation and lasts for a while after defecation. At the same time, it is accompanied by blood in the stool. The bleeding method is that there is blood on the surface of the stool, which does not mix with the stool. Some patients drip or wipe blood after the stool.

    4. Tumor + falling sensation + constipation + bright red = rectal prolapse

    The main symptom of rectal prolapse is the prolapse of a mass from the anus. As the prolapse worsens, it causes varying degrees of anal incontinence, often with mucus outflow, leading to perianal skin eczema and itching. Due to difficulty in emptying the rectum, constipation often occurs, and stools increase frequently, which looks like sheep feces. The mucous membrane is eroded and blood flows out after ulceration.

    So is it enough to only rely on the common features of the disease to identify the disease? Not really. No matter how obvious the symptoms are, it is wrong to rely solely on experience or words before the diagnosis, and more attention should be paid to the specific characteristics of the disease itself. The middle number of the document is just for ease of presentation, not absolute. Once you find symptoms in your body, you should go to the hospital for medical treatment in time to identify the symptoms, so as not to delay the condition.

    These diseases may also cause blood in the stool

    1. Peptic ulcer (black stool)

    It will be accompanied by symptoms such as abdominal pain, heartburn, and spitting out acid water. Because the bleeding site is in the digestive tract, you will see black stools.

    2. Acute hemorrhagic necrotizing enteritis (bloody stools)

    It is usually caused by eating unclean food. First, abdominal pain, diarrhea, bloody stools, nausea, fever, and vomiting. It can be cured within 3 weeks, but it may be more severe. Will be shocked by a lot of blood in the stool.

    4. Ulcerative colitis (pus and blood in the stool)

    The stool is pus and blood, and there is often abdominal pain. The pain can be better after defecation.

    5. Other

Because even hemorrhoids, long-term bleeding can lead to anemia. In severe cases, there will be pallor, fatigue, loss of appetite, palpitations, increased heart rate, shortness of breath after physical activity, edema, etc. The harm to the body cannot be underestimated!
