Possible to Have Breathing Problems (Dyspnoe) Because of a Diastasis Recti?

Most of the time, humans use their diaphragms to breath. The abdominal muscles have a secondary effect. Something intraabdominal can cause breathing problems and a distended abdomen, such as excess fluid. If you are truly short of breath, you should see your medical doctor.

The abdominal musculature play very little role in breathing mechanics.   I would undergo a thorough evaluation by your primary care physician.    I am also concerned that a tummy tuck could worsen your symptoms, not improve them.   Therefore, I would postpone any surgery until the underlying cause of your breathing problem is determined.

Diastasis, or a separation of the sit-muscles is not related to shortness of breath, or directly involved in the mechanics of breathing. Correction will improve the abdominal tone and contour, but don't expect an improvement in breathing.
Best of luck,

Diastasis Recti or weak abdominal muscles do not cause breathing problems. You need an evaluation by an internist or pulmonologist.
