My male personal trainer friend has the same problem. He's very sick for about a year loosing weight and can't even exercise at the gym anymore and is missing college too. He's had every medical test u could imagine including neurological and brain scans and cameras put inside him, colon cleaned. Etc nothing helps! He's been to several of the top hospitals and they check him in for a week then says he's healthy. What can we do??  His symptoms include stomach pain, not being able to eat often, vomiting, throwing up blood, weight loss, dizziness, vertigo, upset stomach. What can we do? Can someone help? He's only 35 years old
