Upper gastrointestinal bleeding

Upper gastrointestinal bleeding 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 refractory bleeding may lead to need for surgery, although this has become uncommon as a result of improved endoscopic and medical treatment. Upper gastrointestinal bleeding affects around 50 to 150 people per 100,000 a year. It represents over 50% of cases of gastrointestinal bleeding. A 1995 UK study found an estimated mortality risk of 11% in those admitted to hospital for gastrointestinal bleeding. Persons with upper gastrointestinal bleeding often present with hematemesis, coffee ground vomiting, melena, or hematochezia (maroon-coloured stool) if the hemorrhage is severe. The presentation of bleeding depends on the amount and location of hemorrhage. A person with upper gastrointestinal bleeding may also present with complications of anemia, including chest pain, syncope, fatigue and shortness of breath. The physical examination performed by the physician concentrates on the following things: Vital signs, in order to determine the severity of bleeding and the timing of intervention Abdominal and rectal examination, in order to determine possible causes of hemorrhage Assessment for portal hypertension and stigmata of chronic liver disease in order to determine if the bleeding is from a variceal source.

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.

Abdominal pain

Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues. Common causes of pain in the abdomen include gastroenteritis and irritable bowel syndrome. About 15% of people have a more serious underlying condition such as appendicitis, leaking or ruptured abdominal aortic aneurysm, diverticulitis, or ectopic pregnancy. In a third of cases the exact cause is unclear.
