A 14-year-old adolescent with pectus excavatum (thoracic depression) was discovered asymptomatic during a school health check-up. Questions were raised about the potential impact on future health and the measures to be taken.
I had pectus excavatum when I was young, but it seemed to have improved during that time, but it seems a bit deeper now. I was checked for calcium deficiency. What type of calcium should I supplement?
