29/f. a little overweight for my age and height. my resting heart rate is always between 105-115 this is extremely high. what could be the cause?

Tachycardia: Newly evident rapid heart rates need evaluation to exclude organic pathology which can be myriad eg thyrotoxicosis, anemia, infections, pulmonary disorder, cardiac disorder et cetera. In the absence of organic underlying pathology it frequently is a reflection of cardiopulmonary deconditioning. Please check in with a local health care provider or via the concierge at this website.
