The consequence of ineffective diaphragm function during breathing is an increased work of breathing. The diaphragm is the primary muscle responsible for facilitating inhalation by contracting and allowing the lungs to expand. If the diaphragm does not function effectively, the body must recruit additional muscles and adopt less efficient breathing patterns to compensate, leading to increased effort and strain.

This can result in a variety of physiological challenges, such as fatigue, respiratory distress, or even a reduced ability to take deep, effective breaths. As a result, individuals may experience breathlessness, particularly during physical activity, as their body struggles to maintain adequate ventilation and gas exchange under the increased demand for effort. Thus, an impaired diaphragm not only makes breathing more laborious but can also lead to further complications and inefficiencies in respiratory mechanics over time.
