Why are People with Pectus Excavatum so Skinny

It is known today that almost all people with pectus excavatum are very skinny. Why? I will here give you my theory about that fact.

First of all today science know that people with pectus excavatum are very healthy in general. There is nothing wrong with the metabolism, that is linked to pectus excavatum. There are no known reasons why skinniness is so common (almost everyone). I have earlier stated that pectus excavatum is caused by a compression and rotation of the thorax causing the sternum to be pulled in by the ribs. The space in the upper part of the thorax will therefore be smaller than it should be. Because of the compression and rotation and the sunken sternum, the diaphragm has less space to operate in and to compensate for the smaller space in the upper part of the thorax the diaphragm starts to expand the lungs in the lower part of the thorax causing the ribs to flare out (not only because of the rotation). And now to the point. It is much more energy demanding to constantly lift the lower part of the ribcage than it is to expand the lungs in the upper part of the thorax. This will rise the demand for food consumption a lot. Most people simply don’t eat that much and this will lead to the skinniness. The diaphragm is quite big so it is common sense that if it works a lot more, the energy consumption by it will rise dramatically.

Conclusion: Over activity in the diaphragm, flared ribs and skinniness are linked together.
