How to distinguish between panic disorder and hyperthyroidism symptoms. I am currently on anti psychotic and anti anxiety medications for almost 10 years. At present my symptoms of excessive sweating rapid heart rate palpitations blood pressure changes have worsened. I sweat excessively in my whole body even in air conditioning room. Since I read about hyperthyroidism on the internet and the symptoms are little similar to panic disorder would need your guidance in my case whether it could be because of hyperthyroidism.
