How can I loose weight simply with minimal exsurize? I am 17 years old (18 in few days) 5ft 0 in and 156 lbs

The only realistic method is decrease of calorific intake and increase in aerobic activity.
(Less food, more exercise)

Does Zumba count as an exsurize method? Love it when I can get to the gym. I work with kids lots of running and workouts( bounce place with a lot of climbing and bouncing)as well. Since my stomach is bad and don't know what going on I can't say what good foods will be avaibul to me.

Zumba is indeed a good form of excersise.
