Is a 110-113 pulse for a 21 year old female abnormal? any reason for concern?

Depends: After exertion, after caffeine, when anxious perfectly normal to have pulse in 110-120 range. If it's always or nearly always in that range, see your doctor and have exam/ekg/blood tests including thyroid function

Depends: If this is a "resting pulse" then it is abnormal. If you have just been on a nice walk, then checked and had this pulse rate then it is normal. A high resting pulse in a young woman needs to be evaluated. Thyroid disease is one possibility. Thanks for trusting Healthtap!
