Excessive intestinal gas and loose stools

For several months now I have been having excessive noisy gas in my intestines. It sounds like rumbling thunder. It feels as though liquide and air are in my intestines. Then I get diarrhea  without cramping or discomfort but it comes out full force. I have no pain at all and have soiled myself several times because it feels like gas. I also feel bloated. Just before this occured I had started to change my diet to more healthy foods and take vitamins and suppliments. I've tried stopping the suppliments and eatting like I use to but I still have this problem.  What can cause this?  I have had to call in out sick from work because of this.
