Typical symptoms include bloody vomit and stool, rectal bleeding, abdominal pain, and other symptoms. These can also be warning signs of a serious underlying health problem.
Bleeding can occur in the upper digestive tract such as the esophagus, stomach or duodenum, which is the first part of the small intestine. Meanwhile, lower digestive tract bleeding will affect the rest of the small intestine, colon, rectum to anus, according to the health website Medical News Today (UK).
Abdominal pain is one of the typical symptoms of enteritis.
This condition can range in severity and can even be life-threatening. In addition to abdominal pain, black stools, and bloody vomit, gastrointestinal bleeding can cause difficulty breathing, fainting, chest pain, weakness, rapid breathing, loss of consciousness, and other symptoms.
Common causes of gastrointestinal bleeding include:
Peptic ulcer
This is one of the most common causes of gastrointestinal bleeding. Ulcers form on the lining of the stomach and upper part of the small intestine. As a result, stomach acid, bacteria, or ingredients in anti-inflammatory drugs further damage the stomach lining.
Esophageal tear
Mallory Weiss syndrome, also known as esophageal tear, is a condition in which a tear occurs in the lining of the esophagus, sometimes causing severe bleeding. People who drink a lot of alcohol and vomit are at high risk for esophageal tears.
Inflammatory bowel disease
Inflammatory bowel disease is a condition in which the intestines become inflamed, leading to digestive symptoms such as abdominal pain, diarrhea, vomiting, and many others. It is one of the most common causes of lower gastrointestinal bleeding. Among the types of inflammatory bowel disease, ulcerative colitis is important. The disease causes the intestinal lining to swell and ulcerate the colon and rectum.
Hemorrhoids
Hemorrhoids occur when veins in the rectum and anus become swollen and bleed. Symptoms of hemorrhoids include bleeding during bowel movements, anal pain, and a visible hemorrhoid mass in the anus.
Colon polyps
Colon polyps are small clumps of abnormal cells that form on the lining of the colon. They can cause bleeding. Although most colon polyps are harmless, some can develop into cancer, according to Medical News Today .
