Graves’ disease and endurance athletes
How are you able to discern what symptoms (ex high heart rate and shortness of breath) are from working out and what is from graves? I (25yo female) am training for a triathlon, and I’ve run 3 marathons in the past, but I’m new to swimming. I’ve always had a really low heart rate, but this recent reoccurrence of graves has caused my heart rate to increase SIGNIFICANTLY when I exercise. However, when I swim my heart rate increases so much I feel like I’m dying and I’m not sure if it’s just because I’m new to swimming or bc my graves is untreated currently. When I swim it gets into the upper 180s/low 190s but then quickly drops to 140s as soon as I rest at the edge of the pool. I have an appointment to see endo next month, and I’m hoping to get a stress test/ecg if possible to check my heart. But anyway it’s so frustrating because I feel so anxious when my heart rate increases so much but I feel like I could swim so much more if my heart rate was slower. Any tips for managing graves and training would be very helpful! Any effects of methimazole with training?
