Ok i'm only repeating what the doc told me. You don't get ulcers from stress, but stress makes it worse. 85% of the population usually get the bacteria by the time they are 5 years old. It gets transfered when one kid comes into contact with another persons
So imagine your 2 years old playing in the sand box and another kid throws up and you put your hands to your mouth. Gross i know.
Not to worry it is treatable with 14 days of heavy antibiotics. I had to be treated for it only cause i'm having Gastric Bypass Surgery and once he closes off the stomach he can't get back in to treat me for ulcers if i get them.
When i explained this to the hubby he accused me of being a vomit eater...
