Are girls suitable to be gastroenterologists?

You can do it. Gender is not a restrictive condition for becoming a gastroenterologist, and both men and women can engage in this profession. Gastroenterologist is the doctor in charge of endoscopy, and needs to have relevant medical knowledge and skills, such as diagnosis and treatment of digestive system diseases, endoscopic operation skills and so on. The work of gastroenterologists requires seriousness, carefulness, patience and responsibility, which have nothing to do with gender.
