I am not sure what the 'other procedures' were, but dying of a tonsillectomy seems a tad, well, wrong.
I understand all operations have risk, but that one isn't real high on the list.
She had her tonsils and adenoids removed and her uvula reduced to help her sleep apnea. Basically this obese girl had a pretty involved procedure to widen her throat so she could breath better, because mommy and daddy wouldn’t cook her healthy food or exercise with her.
