Thank you for requesting me.
There is no indication in your description that indicates a need for a treadmill test.
IN the US, a heart exam and EKG with an internal medicine doctor, or caridologist is adequate.
More importantly, you should not be exercising without having been cleared by your doctor...that can be dangerous.
In addition, to answer your question, you can be fit and overweight, but this does not mean you are healthy being this overweight, as heart disease, cancer and other diseases are increased in this situation.
You should have your thyroid function checked. If your TSH is over 2.5 this is contributing to your problem.
I am a double board certified US doctor and will always give you correct, precise, safe, and comprehensive answers.
When you request me, do so in the medical category, and use a long request lock.
