Possible Cardiac Causes
Heart conditions like arrhythmias or heart failure can cause coughing during exertion due to fluid buildup in the lungs or reduced cardiac output.

Possible Respiratory Causes
Conditions such as asthma, bronchospasm, or GERD may trigger coughing during intercourse due to airway constriction or acid reflux.

Recommended Evaluation
See a healthcare provider for a history, physical exam, and possible tests like ECG, chest X-ray, or pulmonary function tests.

When to Seek Urgent Care
Seek immediate attention if experiencing chest pain, severe shortness of breath, or fainting during intercourse.
