Justrecently lunchtimes, and evenings i have bouts of constant yawning, these can last for about an hour a time, this leaves me feeling anxious and my heart feels fluttery.Once the yawning stops i feel exhausted and as though my body has no air and oxygen in it.. can you tell me whats happening please and what it could be causing it
Thanks for your question on Chat Doctor. I can understand your concern. Yawning and Fluttering sensations in chest are commonly seen with arrhythmia (rhythm disturbances in heart). So consult doctor and get done ECG, 2d echo and Holder monitoring (24 hours continuous recording of ECG). If all these are normal then no need to worry about arrhythmia or other heart diseases. Sometimes, uncontrolled stress and anxiety can also cause similar symptoms. So consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
