Can a “Heavy Chest” Actually Hurt Your Lungs?
The Weight on Your Chest
Women with macromastia (excessively large breasts) often complain of a “heavy” feeling on their chest. They may feel short of breath during exercise or even while resting.
Is this just a sensation? Or does the weight of the breasts actually restrict the lungs from filling with air?
A Randomized Controlled Trial from the University of Hull in the United Kingdom sought to answer this medical question.
The Study: Testing Lung Capacity
The researchers wanted to see if removing the breast weight improved lung function physically. They conducted a high-quality study (Randomized Controlled Trial) with 73 women.
- Group 1 (Surgery): These women had breast reduction surgery immediately (within 6 weeks).
- Group 2 (Control): These women waited 6 months before having surgery.
The doctors used spirometry (lung function tests) to measure how much air the women could inhale and exhale. They compared the results between the two groups.
The Findings: Weight Matters
The results revealed an interesting connection between breast size and breathing.
When they looked at the groups as a whole, the difference wasn’t immediately obvious. However, when they looked closer at the surgery group, they found a clear pattern.
- The Correlation: There was a positive correlation between the weight of the tissue removed and the improvement in lung function.
- The Takeaway: The more weight the surgeon removed, the better the patient’s lung test scores (like Peak Expiratory Flow) became.
- Significant Improvement: Specifically, the study showed a significant improvement in Forced Vital Capacity (FVC). This measures the total amount of air you can forcibly exhale from your lungs.
Why Does This Happen?
Large breasts can act like a physical weight on the chest wall. This external weight may prevent the ribcage from expanding fully when you take a deep breath.
By performing a reduction mammaplasty, the surgeon removes this restriction. This allows the chest wall to move more freely, helping the lungs expand to their full predicted capacity.
Conclusion
If you have massive breasts and struggle to catch your breath, it might not just be “in your head.” It could be a mechanical restriction.
This study confirms that for women with heavy breasts, reduction surgery does more than relieve back pain. It correlates with a measurable improvement in pulmonary (lung) function.
