Researchers evaluated the relationship between lung function measured by barometric whole-body plethysmography and obesity in cats with bronchoconstriction.

Fifty-three cats were included in the study.

Thirty-six cats were considered to be normal-weight cats and 17 cats were considered overweight or obese cats. Overweight cats were mainly male cats and older, and presented lower tidal volume values, lower minute volume values, and lower peak inspiratory and expiratory flows than normal-weight cats.

According to the study, overweight cats showed a more compromised lung function parameters related to restrictive pattern compared with normal-weight cats, but they did not show a higher bronchoconstriction level compared with normal-weight cats.
