my son is 17. HE has been sick for 7 weeks now. Symptoms include weightloss (24 lbs in 7 weeks), vomiting about once a day, loss of appetite, headaches and severe fatigue. We had a stay in the hospital that concluded he had a swollen spleen and a elevated bilirubin count. Liver was fine, mono test negative, hepatitis negative, cbc good,hida scan showed ejection fraction at 37% . My son is extremely sick and no answers so far except for Gilberts disease. He is scheduled for a colonoscopy and a scope tomorrow. Any one ever heard of this?
