Steve Jobs posted a letter to the Apple Community this morning concerning his health which has caused concern within the community and on Wall Street.

Jobs explained that his weight loss throughout 2008 had been a mystery to him and his doctors until recently. The cause of his weight loss is a hormone imbalance that has been "robbing" his body of the proteins he needs to stay healthy.

The treatment for the problem is, "simple and straightforward" according to Jobs who has already begun treatment. The doctors expect Jobs to regain his lost weight by the late Spring.

Steve concluded his letter with the following:

I have given more than my all to Apple for the past 11 years now. I will be the first one to step up and tell our Board of Directors if I can no longer continue to fulfill my duties as Apple’s CEO. I hope the Apple community will support me in my recovery and know that I will always put what is best for Apple first.

So now I’ve said more than I wanted to say, and all that I am going to say, about this.

Steve
