Hello, if only B-ultrasound shows that the spleen is a little big, but there is no lesion and its function is normal. You can pass the civil service physical examination, so don't worry too much about it. The physical examination of civil servants is generally mainly to check whether there are heart diseases, cardiomyopathy, coronary heart disease and other diseases that seriously affect their work. Although you can pass the physical examination of this disease, it doesn't mean that you can do it without treatment. I suggest you do a detailed examination and then treat it correctly under the guidance of a doctor.
