The conversation between human and AI assistant.
[|Human|] I m 16 years old and about 5ft 6 in height. And about 3 months ago I had my appendix taken out which I never went for a check up afterwards. But I have been having severe headaches mainly when go from sitting to standing. I also have been feeling dizzy but rarely, I feel nausea now and then. And just today I have been having a green poop. I have been really tired all the time even though I have been sleeping. Is something wrong?
[|AI|]  Hi, First, you should measure your blood pressure and if you were a woman, and you take oral contraceptive pills, you should ask a gynecologist to adjust the dose. Secondly, if your blood pressure were high, you should do an ECHO and an ECG on your heart. After the surgery you should have done liver and kidney function tests, besides CBC to assess your health and the results of these investigations can help us with your diagnosis. Finally, you should not ignore the psychological factors such as stress. Hope I have answered your query. Let me know if I can assist you further.
