Obesity can lead to breathing difficulties

According to a new study shows that true obesity can lead to breathing difficulties, but the need to further explore the reasons.

Recife, Brazil Boer Nan S. Federal University of W. Ladosky and his colleagues to line 77 of the fat gastroplasty patients (body mass index (BMI) to 40 ~ 69kg/m2) and 28 line of abdominal surgery Pianshou Persons (BMI for 20 ~ 29kg/m2) for the study to measure their lung function, including the breath residual capacity, forced vital capacity, forced expiratory volume, forced vital capacity) and found that obese patients with shallow breathing, which Prompted the weight of adipose tissue on the chest wall of oppression can lead to the results of the abnormal.

The researchers found that when the body mass index increased, decreased vital capacity, which led to flow and volume also declined. Forced expiratory volume and forced vital capacity proportional decline, with the largest amount of ventilation-related.

Ladosky believe that the increase in adipose tissue on the chest wall of the main pressure is to reduce the impact of its compliance, increased difficulty in breathing, leading to still lower the volume and flow, which is more obese patients with persistent severe respiratory diseases.
