When patients with anemia lose weight, they should choose some foods with rich nutrition, high iron content and no obesity. Remember not to blindly choose some low-calorie foods, but also avoid some strenuous exercise to prevent the burden on some hearts from being aggravated. Of course, moderate aerobic exercise is ok. Note that if there are some obvious palpitations and shortness of breath during exercise, you should stop. This is because people with anemia have low blood transport ability.
