what does it mean if my daughter is underweight (23 years old, 80 pounds) has not slept much in the last 2 days due to stress, and is not using drugs of any kind. Her vision blurred, uncontrollable fast heart rate while all her muscles were shaking and at points could not communicate back with me even though she could hear me. Had a hard time breathing and walking. She is extremely active and healthy ..please help
Thanks for your question on Chat Doctor. I can understand your concern. By her symptoms, possibility of stress related symptoms is more. But better to rule out hyperthyroidism as this can cause all such symptoms in young females. So get done serum TSH, Free T3 and free T4. If all these are normal then no need to worry about thyroid diseases. Sometimes, uncontrolled stress and anxiety can cause such symptoms. So consult psychiatrist for her and get done counselling sessions. Try to identify stressor in her life and start working on its solution. She may need anxiolytic Chat Doctor.  Don't worry, she will be alright with counselling sessions and anxiolytic
