Small children are affected by certain diseases that cause them to be noticeably thin compared to normal children. Obviously thin children is one of the clinical symptoms of congenital heart disease. Infants and young children with congenital heart disease are significantly behind the development of children of the same age, manifested by thinness, malnutrition and developmental delay. Congenital cardiovascular disease is the most common type of congenital malformation. With the advances in cardiac diagnostic methods and surgical treatment techniques, the vast majority of congenital cardiovascular diseases can now be definitively diagnosed and surgically corrected and treated, and the prognosis is significantly better than before. The following diseases are also causes of pediatric apparent thinness: 1, pediatric chancre dysentery pediatric chancre dysentery, meridian point alias. See Introduction to Acupuncture Points.

With the progress of cardiac diagnostic methods and surgical treatment technology, the vast majority of congenital cardiovascular disease can get a clear diagnosis and surgical corrective treatment, the prognosis of a significant improvement. 3, chronic pulmonary heart disease chronic pulmonary heart disease (chronic cor pulmonale) is caused by the lung tissue, pulmonary artery blood vessels or thoracic chronic lesions of the lung tissue structure and function abnormalities, resulting in increased pulmonary vascular resistance, pulmonary artery pressure increases, so that the right heart dilation, hypertrophy, with or without the right heart failure heart disease. It can occur in the elderly, but most of them develop from middle age. Most of the pulmonary heart disease in the elderly develops from chronic obstructive pulmonary disease (COPD). It is highly prevalent, especially among smokers, and tends to increase over the years.
