My daughter has finally realized she needs help and has entered an eating disorders program.she is 5 ft 3 inches + weighs 77 lbs..she ended up in emergency from extreme abdominal pain from eating too much and bn unable to purge.its a very sad and heartbreaking disorder for a mother to witness..she is now on a plan to just maintain her weight for the next few weeks..my question is how long will it take to actually start to put on weight and will she have any long term damage or side effects..also her blood pressure is low but pulse rate fast..I am completely in the dark so I hope someone can help.due to patient confidentiality I am not privileged to any information involved with her care but desperately need to know so I can help her any way I can.I don't want my daughter to die :(
