Management of Mild Exertional Dyspnea in Pregnancy

Initial Approach

• For a 28-week pregnant patient with mild shortness of breath on exertion, normal physical examination, and no prior medical conditions, reassurance is the appropriate initial approach without pulmonary function testing, as recommended by the British Journal of Sports Medicine 1, 2

Indications for Pulmonary Function Testing

• Pulmonary function testing is reserved for specific populations, including those with severe respiratory disorders such as COPD, severe asthma, cystic fibrosis, or restrictive lung disease, according to the British Journal of Sports Medicine guidelines 1, 2, 3

Physical Activity Recommendations

• Women with well-controlled mild-moderate respiratory disease who are asymptomatic should be encouraged to maintain physical activity without restriction, as recommended by the British Journal of Sports Medicine 1, 2
• Pregnant women without contraindications should maintain moderate-vigorous physical activity, as encouraged by the British Journal of Sports Medicine 1, 2

Red Flags for Pathologic Causes

• Severe respiratory disease may be indicated by oxygen desaturation with exertion, uncontrolled symptoms, or exercise intolerance below normal pregnancy thresholds, according to the British Journal of Sports Medicine 1, 2

Patient Counseling

• Pregnant women should be instructed to seek immediate care if they develop chest pain, severe dyspnea at rest, palpitations, syncope, or signs of fluid overload, as recommended by the European Heart Journal and the American Journal of Respiratory and Critical Care Medicine 4, 5
• Routine follow-up should be scheduled to reassess symptoms and ensure no progression, as recommended by the British Journal of Sports Medicine 1
