i'm sorry to hear this. it's worrisome for both mother and daughter isn't it? your daughter needs to seek medical attention for this. i'm not talking about rushing to the emergency room but she should make an appointment with a health care provider for an evaluation. it's always a concern when someone is losing weight without trying to. many conditions can cause unintentional weight loss including hyperthyroidism. only a physical exam and additional testing by a medical professional can diagnose what's causing your daughter's symptoms. i wish you both the best!
my daughter keeps loosing weight and she is not trying to she feels sick when she tries to eat
