GASTROINTESTINAL TRACT BLEEDING
Full Answer Section
Diverticulosis is a condition in which pouches develop in the wall of the colon. These pouches can become inflamed and bleed, leading to diverticulitis. Other causes of GI tract bleeding include:- Cancer of the digestive tract
- Inflammatory bowel disease (IBD), such as Crohn's disease and ulcerative colitis
- Mallory-Weiss tear, which is a tear in the lining of the esophagus caused by vomiting
- Hemorrhoids, which are swollen veins in the rectum
- Anal fissures, which are small tears in the lining of the anus
- Alcohol abuse: Alcohol can irritate the lining of the stomach and duodenum, increasing the risk of peptic ulcers.
- Poorly controlled peptic ulcer disease: Peptic ulcers that are not properly treated can become larger and deeper, increasing the risk of bleeding.
- Overweight: Excess weight can increase the pressure on the stomach and duodenum, making them more likely to bleed.
- Recent weight loss: Rapid weight loss can lead to electrolyte imbalances, which can increase the risk of bleeding.
- Hematemesis (vomiting blood)
- Melena (black, tarry stools)
- Hematochezia (bright red stools)
- Hematochezia (bright red stools)
- Rectal bleeding
- Maroon-colored stools
- Intravenous fluids to replace blood loss
- Blood transfusions
- Endoscopic hemostasis, which is a procedure to stop bleeding with a thin, flexible tube with a camera and light attached (endoscope)
- Medications to reduce the production of acid in the stomach
- Surgery to remove the affected area of the digestive tract
- Surgery to bypass the affected area of the digestive tract
- Monitoring vital signs and assessing for signs and symptoms of bleeding
- Administering intravenous fluids and medications as prescribed
- Providing education and support to patients and their families
- Monitoring stool output and color
- Preventing complications, such as shock and infection
Sample Solution
Pathophysiology of Gastrointestinal (GI) Tract Bleeding
GI tract bleeding can occur anywhere in the digestive tract, from the esophagus to the rectum. The most common causes of GI tract bleeding are peptic ulcers, esophageal varices, and diverticulosis.
Peptic ulcers are sores that develop in the lining of the stomach or duodenum (the first part of the small intestine). They are caused by a combination of factors, including acid and pepsin (a digestive enzyme) produced by the stomach.
Esophageal varices are enlarged veins in the esophagus. They are caused by portal hypertension, which is high blood pressure in the portal vein. The portal vein carries blood from the digestive organs to the liver.
