off the top of my head
  1. H.Pylori
  2. gastritis
    (caused by the H.Pylori infection of course!)
  3. tuberculosis
    it was just mono :/
  4. Lyme disease
    actually this was my boyfriend when he got a rash once. I lowkey wondered though
  5. pregnancy
    not a disease but not a desirable
  6. diabetes
    same WebMD streak as the preggo scare!
  7. brain cancer
    nope! it was just a hangover
