Slow growth

Introduction The age and gender height of children are 2 standard deviations below the median, but less than or equal to the median minus 3 standard deviations, which is moderate growth retardation, such as lower than the same age and gender reference population standard. The median of the reference population was reduced by 3 standard deviations for severe growth retardation. This indicator mainly reflects chronic malnutrition in the past or long-term.

Cause

Often secondary to medical and surgical reasons such as chronic diarrhea, short bowel syndrome and malabsorption. The non-medical cause is a shortage of poor food. Lack of nutritional knowledge, parents ignore scientific feeding methods. After one or two years of birth, the growth gradually slows down. The body is short and well-proportioned. The appearance of adulthood is still like children. There are many subcutaneous fats and muscles underdeveloped. The bones are mature, the bone age is younger, and the intelligence is equal to age.

Differential diagnosis

It should be distinguished because of malnutrition and slow growth due to diseases such as stagnation.

Malnutrition is a chronic nutritional deficiency caused by a chronic deficiency of protein and/or total calories, which is more common in infants under 3 years of age. Mainly manifested as progressive weight loss, weight loss or edema, severe cases often have internal organ dysfunction, affecting the heart, liver, kidney and other organ functions.

Dyxiaozheng (daixiaozheng) is also known as "Kettering disease." It is a metabolic disease caused by congenital thyroid hypoplasia or hypofunction. The main manifestation is that the growth and development process is obviously blocked, especially the skeletal system and nervous system.
