A peptic ulcer that develops in the digestive tract may begin to bleed, which could lead to a rapid loss of blood.
The term ulcer means a sore that doesn't heal quickly. Ulcers can occur almost anywhere on the body, usually resulting from injuries, illnesses, or infections. They can be short-lived or ongoing.
Most commonly, when people refer to an ulcer, they are referring to peptic ulcers that develop in the digestive tract. The term peptic means it is related to acid.
