Gastrointestinal Medicine Associates, P.C.Logo Design Contest

Hi, Entry #22 - here I am trying to convey the company initials and incorporate imagery of your area of expertise.

#21- Can you insert a colon into the design? So there is a colon and a stomach? Can we also play with the colors a little also? Our main practice color is Dark Red, almost crimson. Can you make the design that color. Also, can you incorporate "GMA" into it?
