Do i need endoscopy?

I was recently told I had peptic ulcer disease. The doctor insisted I undergo an upper endoscopy. I am only 42. Is this necessary?
Some of the biggest abusers of medical procedures just for financial gain are the gastroenterologists. Everyone who walks into their office nowadays get a scope down the mouth or up the arse. And this is not because they love your body parts but because they make a lot of money. Any astute doctor can make a clinical diagnosis of peptic ulcer disease. Sometimes a trial of peptic ulcer drugs may help determine the cause. My best advice to you is get some over the counter anti-ulcer medication and if you have peptic ulcer disease, the relief will be instant (in a matter of minutes). If that works you do not need any endoscopy. All this bullshit about Helicobacter pylori and taking 3 drugs is hogwash. It is just another money making scheme in medicine. Please change your doctor, because he /she is not interested in your welfare but your money.
