<s>[INST] Dear Dr. Grief, My son is 26 yrs. old and will soon graduate from Law School. It has been his dream to serve in the Armed Forces. He is currently applying to the National Guard. However, he has a history of Hereditary Spherocytosis. He was diagnosed at 16 yrs. old and had a laparoscopic procedure to remove his spleen and gallbladder. He has no anemia or other medical issues. His recruiter does not know if this medical history will disqualify him from military service. I would appreciate your medical opinion. Thank you! [/INST] Hi thanks for contacting Chat Doctor .... Noted hereditary phagocytosis is cause for congenital hemolytic anemia... Your children spleen and gall bladder removed. So he might have more chances of bacterial infection like pneumococci, h.influenza etc. So its vaccine taken if feasible and advise by doc. As gall bladder removed he is advised to take low fat diet.... Although he is alright right now but army not advisable.... Still if he joins army care taken regarding taking low fat diet and whenever fever consult army doctor immediately ... In the fitness certificate country rules has to be read whether he is eligible for army in your country or not. Take care. Hope your concern solved. </s>
