I am heat sensitive and have been for years, it makes my heart beat fast and makes me feel tired and panicky , thyroid normal am 37 , low bp?

Unusual: Could be a neurologic issue. The anx 3.0 is a device that evaluates how the nervous system communicates. Also neurotransmitter imbalances may contribute and can be assessed by urine testing pharmasan labs.

Sweaty?: If you're heat sensitive, tired with low bp, consider dehydration. Two major causes: sweating and not drinking enough? (if you have other fluid losses like diarrhea, vomiting, or bleeding, they would also contribute to your symptoms). Panicky does not fit- you may have two distinct issues. Uncontrolled diabetes, the rare entity, diabetes insipidus, and some drugs could contribute.
