Gastrointestinal bleeding is a common acute and critical condition in clinical practice. Of course, if the cause can be identified in a timely manner and active rescue and treatment are carried out, the prognosis is generally good.
If the bleeding volume is large and rapid, and timely treatment is not provided, those with mild conditions may have sequelae of varying degrees, while those with severe conditions may die quickly.

When the amount of gastrointestinal bleeding is relatively large, it can cause a series of complications. For example, it can cause blood supply disorders to the brain tissue. For elderly patients with cerebral arteriosclerosis, even if the bleeding volume is not very large, it may induce cerebral infarction and even disable the patient.
When severe anemia occurs, it can cause hemorrhagic shock. In addition, a large amount of bleeding may induce myocardial infarction and heart failure.
