I ve also steadily gained about 20 pounds over the last year and 1/2.
<bot>: Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms could be related to a lung disorder or overweight. For this reason, I would recommend consulting with your attending physician for a careful physical exam and some tests: - a chest X-ray study and pulmonary function tests- a resting ECG and cardiac ultrasound to examine your heart function and structure-thyroid hormone levels for thyroid dysfunction- blood electrolytes for possible imbalance. An ambulatory 24-48 hours ECG monitoring would help examine your heart rhythm trends for a prolonged time and exclude possible cardiac arrhythmia. Hope you will find this answer helpful! Wishing all the best,
