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.
An upper GI bleed is more common than lower GI bleed. [2] An upper GI bleed occurs in 50 to 150 per 100,000 adults per year. [8] A lower GI bleed is estimated to occur in 20 to 30 per 100,000 per year. [2] It results in about 300,000 hospital admissions a year in the United States. [1] Risk of death from a GI bleed is between 5% and 30%.
Hemorrhoids are common in pregnancy as a result of constipation and increased intra-abdominal pressure. Hemorrhoids can cause bleeding, pain, and itching. [32] Treatment is symptomatic, including improving underlying constipation. Symptoms may resolve spontaneously after pregnancy, although hemorrhoids may remain in the days after childbirth. [33]
A lower gastrointestinal bleed is defined as bleeding originating distal to the ileocecal valve, which includes the colon, rectum, and anus. [2] 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 the entire area of the jejunum and ileum.

These are normal physiological adaptations that cause changes in behavior, the functioning of the heart, blood vessels, and blood, metabolism including increases in blood sugar levels, kidney function, posture, and breathing. During pregnancy numerous hormones and proteins are secreted that also have a broad range of effects.
The scoring system uses clinical criteria (increasing age, co-morbidity, shock) as well as endoscopic finding (diagnosis, stigmata of acute bleeding). It is named for Professor Tim Rockall, who was the main investigator and first author of the studies that led to its formulation.
It takes place in normal pregnancies as well as when there are obstetric or trauma related complications to pregnancy. Normally the maternal circulation and the fetal circulation are kept from direct contact with each other, with gas and nutrient exchange taking place across a membrane in the placenta made of two layers, the syncytiotrophoblast ...
Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).
