Are there non-surgical ways of treating a funnel chest?

No: Pectus excavatum is the fancy medical term for this condition. For most individuals it is only a cosmetic problem. Rarely does it interfere significantly with heart or lung function. Several surgical approaches can be done. No know exercises have been shown to be of any value.

Perhaps: Some investigators have described the use of suction devices. However the data is incomplete and more investigation is required.

Not usually: Funnel chest or pectus excavatum is a defect of the chest wall and the ribs and stenrum that form the chest wall. These structures can be very rigid in an adult and somewhat compliant in an adolescent. Exercise will help flexibility and develop muscle mass but not change the defect. The defect can be treated by a nuss procedure.
