<s>[INST] I had an ultrasound performed and it stated my liver was slightly enlarged at 17 cm. I am 31 years old female and rarely drink. I quit smoking over 4 months ago. I am not on any particular medicine except lo loestrin birth control. I am 5'4 and weigh 158. I walk and jog everyday. Everything else on ultrasound and hida scan were normal. [/INST] Hi and welcome to HCM. Thank you for your query.ENlarged liver can be found in healthy epople and this doesnt indicate any pathology. If tehre was no other lesion or you dont have any symptms you should not worry at all. Loestrin has some liver side effects such as adenoma and raising LFT,but this is rare and benign. YOu should just do once a yeasr US follow up and thats all.  WIsh you good health. </s>
