Although the headline sounds sensational, to Heather Hendershot this was reality. The 25 year old was at home watching TV with her husband when her Apple Watch alerted her of a resting heart rate of around 120 bpm; much higher than a woman her age should have without physical activity.
As the alerts kept coming and her heart beat rate continued to rise, she checked her heart rate as well, confirming that her heart rate was increased, and continued to rise until around 160 bpm. Alerted by her elevated heart rate, the next day Hendershot decided do get checked out by a doctor.
When Hendershot checked into the Stormont Vail Health’s emergency room, having never shown any symptoms before, Hendershot was diagnosed with moderate to severe hyperthyroidism. This is a condition that affects about 1 in 100 people in the US and can be fatal if left untreated. According to the American Thyroid Association symptoms vary, but can include weight change, irritability, fatigue, increased sweating, and heart palpitations as generally all bodily functions tend to speed up.
This story was first reported by the Topeka Capital-Journal, where Hendershot’s treating doctor Alan Wynne, an endocrinologist at the Cotton O’Neil Diabetes and Endocrinology center at Stormont Vail Health, said that “I’ve been doing this 25 years and it’s the first time ever I’ve heard someone tell me they didn’t notice anything and were later diagnosed with severe hyperthyroidism”
Now don’t get freaked out when your Apple Watch shows you an increased heart rate, it doesn’t automatically mean you also suffer from a condition like hyperthyroidism. There are a number of reasons why healthy people experience this. However if this problem persists you may want to consult your doctor and remember to get your annual check ups and blood work done!
