Look up information on autonomic dysfunction and postural orthostatic tachycardia syndrome (POTS). POTS in particular can be caused by several things (such as surgery) or even secondary to another disease, such as with one person who posted in this section was recently diagnosed with Hashimoto's and POTS.
