Hello,
With the question “What is dyspnea when lying on your back? ”, the doctor would like to answer as follows:
With the symptom of shortness of breath alone, it is difficult to make an accurate diagnosis of the cause that needs to be combined with other symptoms or need additional tests and investigations to support diagnose. Given your age and shortness of breath, doctors are less likely to think about cardiovascular causes. Aim for pleuro-pulmonary (inflammation) cause or pathology Gastroesophageal reflux disease. However, more specific evaluation is needed to make an accurate diagnosis.
If you still have questions about shortness of breath when lying on your back, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
