Pediatric turtle chest (Gui Xiong) refers to a condition where the sternum protrudes and swells, resembling the shell of a turtle, hence the name. This arises from stagnant heat in the Lung meridian. This condition is often caused by the nursing mother consuming excessive spicy, fried, or rich flavors. It may also result from the nursing mother suffering from Qi stagnation and depression, transmitting these emotions through breast milk to the infant. Additionally, exposure to summer heat combined with cold drinks, or cooling off while exposed to wind during breastfeeding, can also induce this condition. One must carefully assess the pathology and treat accordingly; if left untreated for a long time, it becomes a chronic disease.
