Hematochezia
Hematochezia is a form of blood in stool, in which fresh blood passes through the anus while defecating. It differs from melena, which commonly refers to blood in stool originating from upper gastrointestinal bleeding (UGIB). The term derives from Greek αἷμα ("blood") and χέζειν ("to defaecate"). Hematochezia is commonly associated with lower gastrointestinal bleeding, but may also occur from a brisk upper gastrointestinal bleed. The difference between hematochezia and rectorrhagia is that rectal bleeding is not associated with defecation; instead, it is associated with expulsion of fresh bright red blood without stools. The phrase bright red blood per rectum is associated with hematochezia and rectorrhagia. Causes In adults, most common causes are hemorrhoids and diverticulosis, both of which are relatively benign; however, it can also be caused by colorectal cancer, which is potentially fatal. In a newborn infant, haematochezia may be the result of swallowed mater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melena
Melena is a form of blood in stool which refers to the dark black, tarry feces that are commonly associated with upper gastrointestinal bleeding. The black color and characteristic strong odor are caused by hemoglobin in the blood being altered by digestive enzymes and intestinal bacteria. Iron supplements may cause a grayish-black stool that should be distinguished from melena, as should black coloration caused by a number of medications, such as bismuth subsalicylate (the active ingredient in Pepto-Bismol), or by foods such as beetroot, black liquorice, or blueberries. Causes The most common cause of melena is peptic ulcer disease. However, any bleeding within the upper gastrointestinal tract or the ascending colon can lead to melena. Melena may also be a complication of anticoagulant medications, such as warfarin. Causes of upper gastrointestinal bleeding that may result in melena include malignant tumors affecting the esophagus, stomach or small intestine, hemorrhag ...

Gastrointestinal Bleeding
Gastrointestinal bleeding (GI bleed), also called gastrointestinal hemorrhage (GIB), is all forms of bleeding in the gastrointestinal tract, from the mouth to the rectum. When there is significant blood loss over a short time, symptoms may include vomiting red blood, vomiting black blood, bloody stool, or black stool. Small amounts of bleeding over a long time may cause iron-deficiency anemia resulting in feeling tired or heart-related chest pain. Other symptoms may include abdominal pain, shortness of breath, pale skin, or passing out. Sometimes in those with small amounts of bleeding no symptoms may be present. Bleeding is typically divided into two main types: upper gastrointestinal bleeding and lower gastrointestinal bleeding. Causes of upper GI bleeds include: peptic ulcer disease, esophageal varices due to liver cirrhosis and cancer, among others. Causes of lower GI bleeds include: hemorrhoids, cancer, and inflammatory bowel disease among others. Small amounts o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemorrhoid
Hemorrhoids (or haemorrhoids), also known as piles, are vascular structures in the anal canal. In their normal state, they are cushions that help with stool control. They become a disease when swollen or inflamed; the unqualified term ''hemorrhoid'' is often used to refer to the disease. The signs and symptoms of hemorrhoids depend on the type present. Internal hemorrhoids often result in painless, bright red rectal bleeding when defecating. External hemorrhoids often result in pain and swelling in the area of the anus. If bleeding occurs, it is usually darker. Symptoms frequently get better after a few days. A skin tag may remain after the healing of an external hemorrhoid. While the exact cause of hemorrhoids remains unknown, a number of factors that increase pressure in the abdomen are believed to be involved. This may include constipation, diarrhea, and sitting on the toilet for long periods. Hemorrhoids are also more common during pregnancy. Diagnosis is made by lo ...

Upper Gastrointestinal Bleeding
Upper gastrointestinal bleeding (UGIB) is gastrointestinal bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. Blood may be observed in vomit or in altered form as black stool. Depending on the amount of the blood loss, symptoms may include shock. Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin. Significant upper gastrointestinal bleeding is considered a medical emergency. Fluid replacement, as well as blood transfusion, may be required. Endoscopy is recommended within 24 hours and bleeding can be stopped by various techniques. Proton pump inhibitors are often used. Tranexamic acid may also be useful. Procedures (such as TIPS for variceal bleeding) may be used. Recurrent or refr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Gastrointestinal Bleeding
Lower gastrointestinal bleeding (LGIB) is any form of gastrointestinal bleeding in the lower gastrointestinal tract. LGIB is a common reason for seeking medical attention at a hospital's emergency department. LGIB accounts for 30–40% of all gastrointestinal bleeding and is less common than upper gastrointestinal bleeding (UGIB). It is estimated that UGIB accounts for 100–200 per 100,000 cases versus 20–27 per 100,000 cases for LGIB. Approximately 85% of lower gastrointestinal bleeding involves the large intestine, 10% are from bleeds that are actually upper gastrointestinal bleeds, and 3–5% involve the small intestine. Signs and symptoms A lower gastrointestinal bleed is defined as bleeding originating distal to the ileocecal valve, which includes the colon, rectum, and anus. LGIB was previously defined as any bleed that occurs distal to the ligament of Treitz, which included the aforementioned parts of the intestine and also included the last 1/4 of the duodenum and t ...

Blood In Stool
Blood in stool looks different depending on how early it enters the digestive tract—and thus how much digestive action it has been exposed to—and how much there is. The term can refer either to melena, with a black appearance, typically originating from upper gastrointestinal bleeding; or to hematochezia, with a red color, typically originating from lower gastrointestinal bleeding. Evaluation of the blood found in stool depends on its characteristics, in terms of color, quantity and other features, which can point to its source, however, more serious conditions can present with a mixed picture, or with the form of bleeding that is found in another section of the tract. The term "blood in stool" is usually only used to describe visible blood, and not fecal occult blood, which is found only after physical examination and chemical laboratory testing. In infants, the Apt test, a test that is particularly useful in cases where a newborn has blood in stool or vomit, can be us ...

Ulcerative Colitis
Ulcerative colitis (UC) is one of the two types of inflammatory bowel disease (IBD), with the other type being Crohn's disease. It is a long-term condition that results in inflammation and ulcers of the colon and rectum. The primary symptoms of active disease are abdominal pain and diarrhea mixed with blood ( hematochezia). Weight loss, fever, and anemia may also occur. Often, symptoms come on slowly and can range from mild to severe. Symptoms typically occur intermittently with periods of no symptoms between flares. Complications may include abnormal dilation of the colon ( megacolon), inflammation of the eye, joints, or liver, and colon cancer. The cause of UC is unknown. Theories involve immune system dysfunction, genetics, changes in the normal gut bacteria, and environmental factors. Rates tend to be higher in the developed world with some proposing this to be the result of less exposure to intestinal infections, or to a Western diet and lifestyle. The remova ...

Beetroot
The beetroot (British English) or beet (North American English) is the taproot portion of a ''Beta vulgaris'' subsp. ''vulgaris'' plant in the Conditiva Group. The plant is a root vegetable also known as the table beet, garden beet, dinner beet, or else categorized by color: red beet or golden beet. It is also a leaf vegetable called beet greens. Beetroot can be eaten raw, roasted, steamed, or boiled. Beetroot can also be canned, either whole or cut up, and often are pickled, spiced, or served in a sweet-and-sour sauce. It is one of several cultivated varieties of ''Beta vulgaris'' subsp. ''vulgaris'' grown for their edible taproots or leaves, classified as belonging to the Conditiva Group. Other cultivars of the same subspecies include the sugar beet, the leaf vegetable known as spinach beet (Swiss chard), and the fodder crop mangelwurzel. Etymology ''Beta'' is the ancient Latin name for beetroot,Gledhill, David (2008). "The Names of Plants". Cambridge University Press. ...

Reddish Stool In Toilet Bowl Water Due To Dragon Fruit Consumption
Reddish is an area of the Metropolitan Borough of Stockport, Greater Manchester, England, south-east of Manchester city centre. At the 2011 census, the population was 28,052. Historically part of Lancashire, Reddish grew rapidly in the Industrial Revolution and still retains landmarks from that period, such as Houldsworth Mill, a former textile mill. Reddish Vale is a country park. History Toponymy Reddish is recorded as Redich (1205, 1212), Redych, Radich (1226), Radish, Rediche (1262), Redditch (1381), Redwyche, Radishe and Reddishe (16th century).Farrer and Brownbillpp. 326–9Booker, p. 197. The name either means "reedy ditch" ( OE ''hrēod-dīc'') or "red ditch" (OE ''rēad-dīc''). Ekwall (1922) allows either form, stating "red" is less probable; Mills (1991) and Arrowsmith (1997) only give the "reed" option.Arrowsmith, p. 23. The ditch referred to is possibly the Nico Ditch, an earthwork of uncertain origin bordering Reddish, Manchester and Denton. Folklore ha ...

Pitaya
Pitaya () or pitahaya () (common names strawberry pear or dragon fruit) is the fruit of several cactus species indigenous to the region of southern Mexico and along the Pacific coasts of Guatemala, Costa Rica, and El Salvador. Pitaya is cultivated in East Asia, South Asia, Southeast Asia, the United States, the Caribbean, Australia, Brazil, and throughout tropical and subtropical regions of the world. ''Pitaya'' usually refers to fruit of the genus ''Stenocereus'', while ''pitahaya'' or ''dragon fruit'' refers to fruit of the genus '' Selenicereus'' (formerly ''Hylocereus''), both in the family Cactaceae. The common name in English derives from the leather-like skin and scaly spikes on the fruit exterior, resembling dragon skin. Depending on the variety, pitaya fruits may have sweet- or sour-tasting flesh that can be red, white, or yellow in color. Vernacular names These fruits are commonly known in English as strawberry pear or dragon fruit, a name used since 1963, appare ...
