Anemia caused by gastrointestinal bleeding usually requires 2 to 3 months after the bleeding in the gastrointestinal tract stops before gradual recovery, and the exact recovery time is related to the severity of the condition and one’s own physical condition. Anemia can be treated with medication, food and other methods. 1. Drug treatment: If anemia is too serious, drug treatment is needed. Commonly used medications include iron, etc., but they need to be taken in accordance with the doctor’s instructions, and need to be taken on a long-term basis, on time, and with regular check-ups. 2. Food treatment: daily you can eat more food rich in vitamin C, such as tomatoes, lettuce, hawthorn, apples, oranges, etc. You can also eat more fresh lean meat, nuts, animal offal, etc., which can promote iron absorption.
