E20-E35: Disorders of other endocrine glands

E30: Disorders of puberty, not elsewhere classified

Disorders of puberty, not elsewhere classified, refers to a set of conditions related to abnormal growth and sexual development during puberty. This group is characterized by challenges in the developmental process that takes children through physical changes like growth spurts and the development of secondary sexual characteristics such as breasts in girls and deepening voices in boys. These disorders can often be instigated by several factors such as genetic abnormalities, hormonal imbalances, malnutrition, chronic illnesses, or certain types of tumors. Common symptoms include delayed or early onset of puberty, abnormal growth patterns, or the absence or irregular development of secondary sexual characteristics. These disorders typically progress over time and directly affect the endocrine system, which is responsible for hormonal regulation in the body. Extensive medical assessment is often required to accurately diagnose and manage these conditions.
