Hi thanks for contacting HCM. Noted she is very young in age... She has only gall stone problem... It is usually remain asymptomatic in which nothing is done. If it is symptomatic then further treatment given.... Noted she had spleenomegaly two year back. It could be from one of the hemolytic anemia causes. For which peripheral blood smear examination done with electrophoresis... According to cause treatment done... So according to history here nothing seems much danger.... Get her to physician for physical examination with liver and spleen palpation with lymph node palpation and accordingly investigated.... Take care. Dr.Parth Goswami
