1000-Lb Sistersstar Amanda Halterman has been struggling with health issues for the last few months, and after a new update I think things are scarier than they seem surrounding her heart health and what her next steps are. Throughout 1000-Lb Sisters season 6, Amanda was a major source of help for Amy Slaton and Tammy Slaton. As the women's older sister, she knew how to be there for them with tough love in difficult moments, and knew when to step back and pump the brakes. Amanda made it clear that she was there for her family no matter what.
