Gastrointestinal bleeding does not usually affect life expectancy after treatment, but if the bleeding is large, it may lead to life-threatening hemorrhagic shock. Gastrointestinal bleeding can be categorized into upper gastrointestinal bleeding and lower gastrointestinal bleeding according to the location of the bleeding. Symptoms of upper gastrointestinal bleeding are mainly vomiting blood, black stools, etc.; symptoms of lower gastrointestinal bleeding are mainly blood in the stool. Generally speaking, gastrointestinal bleeding can be treated and will not affect the patient’s life expectancy through active treatment. However, if the bleeding is large and is not stopped in time, it may lead to palpitations, fainting, and shock, which may endanger the patient’s life. If symptoms of gastrointestinal bleeding appear, you should seek medical treatment in time to avoid delaying the condition.
