My Daughter Is 11yrs Old And Has Body Aches, Joint

My daughter is 11yrs old and has body aches, joint pain, no ambition to walk to school, snores like a grown adult, has weight gain, breathing problems when ever we tickel her for a minute and she cant breath at all and her eating habits we cut her back on her portions and still gains weight and goes to the bathroom every 5-10 minutes.
