So far my lab work is consistent with hyperparathyroidism. Nevertheless I have had many symptoms of dysautonomia, such as lightheadedness, weakness, muscle aches, palpitations, shortness of breath, disregulation of temperature, nausea and other gastrointestinal symptoms, loss of appetite, dilated pupils at inappropriate times, fatigue, headaches, tachycardia, postural orthostatic tachycardia, sleep disorders, numbness, parasthesia, light sensitivity, noise sensitivity, and "reactive hypoglycemia" with normal glucose levels. There are few references online that link these two conditions. There is not much, however. Does anyone know about overlap between these conditions? Can one cause the other? Does anyone else have experience having both of these conditions?
