Hi. I Am A 21 Year Old Female. I Weigh

Posted on Sun, 4 Aug 2019

Question: Hi. I am a 21 year old female. I weigh 104 lbs. I used to weigh 110 lbs but I started losing weight about 2-3 months ago for no reason. What is unusual though is my resting heart rate. About 4 months ago my resting heart rate used to be in the 70s. But then it started going upend it hovered around the mid to high 80s for a while. Then it went down a bit to the low 80s, but about 3 weeks ago it started climbing again, and now it is 92. I wear a Fitbit and that's what it says, but I don't know if it maybe wrong, but I don't think so. I had gone to my doctor about it, but before it started rising, and he said it was tachycardia because my heart was beating fast. But I went to him more recently and he said my pulse was 70, which at that moment it was, but for the majority of the day my heart rate is above 100, even when I'm just sitting. Is there any explanation for this? I also occasionally get chest pains, it's bearable but it still hurts a lot.

Also, I take Venlafaxine, Wellbutrin and Vyvanse. My doctor said it was the Vyvanse that was causing the fast heart rate, so he reduced it, which got rid of my constant tremors, although I do still get it from time to time. And it did stop the palpitations; however, my resting heart rate is in fact increasing despite all of that.

Hello!

Welcome to Ask a Doctor service!

Regarding your concern, I would explain that the palpitations and the weight loss could be related to vyvanse adverse effects.

Anyway, before coming to this conclusion, I would recommend checking thyroid hormone levels for possible thyroid gland dysfunction and blood electrolytes for possible imbalances.

An ambulatory 24-48 hour ECG monitoring would help examine your heart rhythm trends for a prolonged period of time and exclude possible cardiac arrhythmia. A cardiac ultrasound would help examine your heart function and structure.

If all the above tests result normal,I would recommend stopping vyvanse and switching to another drug.

Hope you will find this answer helpful!

My doctor checked my thyroid hormone levels and they came back normal. But for the other two, I haven't done them, and I don't think my doctor will do it either.

I am not sure how to get him to do it because he says that he needs a reason before he can do it, and he doesn't think there is a reason. Am I allowed to ask him to do it, or does he have to think it's necessary to do it?

Hello again!

The best thing would be consulting with a cardiologist and discuss about those tests.

Another possible option would be to stop vyvanse and see if your situation improves. In such case, you should consider vyvanse as the main cause of your complaints.
