Stress and illness

The last time I got sick i had to have my apendix removed. The doctors couldnt figure out why there was infection in my stomach that cause my apendix to swell. Did stress cause this? It has been known that when you stress it can lead to ulcers, strokes and possibly heart attacks. So please pay attention to your body it has a story to you. When people start getting sick they could experience headaches or stomach aches for no appearent reason. Could that mean your starting to get sick? Maybe if you know yourself well enough.
  As an employer, knowing myself and what can cause me to stress maybe I can help my employees. I could find the cheapest health insurance to offer my employees. Have the resources to help my employees. Finally listen to them. They might already have the resources and just need someone to talk to. That was how my boss helped me when I was employed through someone else.
