Here are the clinical manifestations of childhood obesity: childhood obesity can occur at any age, even fetus can also occur, most commonly in infancy, 5 to 6 years old children and adolescents. Affected children usually have a strong appetite, like to eat sweets and high-fat food.

Severe obesity restricts chest expansion and diaphragm movement due to excessive accumulation of fat, resulting in reduced pulmonary air exchange, causing hypoxia, shortness of breath, cyanosis, increased red blood cells, heart enlargement or congestive heart failure or even death, called obesity-poor oxygen exchange syndrome. Clinically, the diagnosis of childhood obesity is measured by the calculated value of the child’s weight and length. If a child’s weight reaches or exceeds 20% of the average standard weight calculated by length, has a history of over-nutrition, under-activity or family history of obesity, and is uniformly obese without other abnormal clinical manifestations, it can be diagnosed as simple obesity. Weight more than 20% to 30% of the standard weight is mild obesity, more than 30% to 50% is moderate obesity, >50% is severe obesity. In addition to the above clinical manifestations, the physical examination of the affected children is also different from normal children. Obese children’s physical examination can be seen in the children’s subcutaneous fat, but uniform distribution, abdominal expansion and sagging, serious obesity can be due to excessive subcutaneous fat, so that the pleura, buttocks and thighs skin white or purple lines; because of excessive weight, walking two lower limbs overload can lead to knee valgus and flat feet. Excess chest fat in girls should be distinguished from breast development, which can be palpable as hard nodules in the breast tissue.

Obese children often develop sexually earlier, so their final height is often slightly lower than that of normal children.
