Gastric ulcer with vomiting blood means that the bleeding volume is more than 500 ml, and this condition may be life-threatening for the person. Its impact on health mainly depends on the amount of bleeding and whether there is immediate hemostasis, and also whether the ulcer is malignant, which can also affect the person’s life expectancy. If the bleeding is heavy and there is no immediate hemostasis, shock is likely to occur and even endanger a person’s life. In addition, if the bleeding ulcer is malignant, which is often referred to as “stomach cancer”, it will affect the life expectancy of a person, and the survival time will not exceed one year. Excluding the above cases, benign gastric ulcers that do not bleed much, or with immediate hemostasis and blood transfusion to replenish blood volume, can recover as normal and will not affect a person’s life expectancy.
