A year ago I was prescribed 22,000$ dollar immunosuppressant injection called Stelara to combat Chrons disease. This was all after a pretty sudden surgery caused by perforations in my small intestine. I lose my insurance in a couple months so I am not sure what i will do then. What exactly causes this disease and what are natural ways to combat it? I asked my Jo o ish pill pushing doctor if i should do any preventative maintenance in regards to exercise and diet and he said No just dont smoke tobbaco. I find it hard to believe a gastrointestinal disease has nothing to do with the food you ingest.
