Some people may experience significant stomach discomfort after pregnancy, which is related to hormonal changes in the body. When pregnant mothers experience frequent vomiting, it may cause damage to the mucous membrane of the throat and lead to bleeding, but the amount of bleeding is small, so pregnant mothers can rest assured. If the symptoms of vomiting blood are more serious and the bleeding volume is larger, it is considered that there may be an esophageal cardia mucosal tear syndrome. There is also the possibility of gastric bleeding caused by acute erosive hemorrhagic gastritis. There is also a possibility that the pregnant mother has an upper gastrointestinal tract disease, such as peptic ulcer, which may worsen after pregnancy and cause bleeding from the ulcer. If a pregnant mother has a large amount of stomach bleeding, she needs to go to the hospital in time and cooperate with the doctor to give active treatment.
