Pediatric Endocrinology

Pediatric endocrinology is a subspecialty that deals with the diagnosis, treatment, and follow-up of hormonal system diseases during childhood and adolescence. Hormones are chemical messengers that regulate the body's fundamental vital functions such as growth, development, metabolism, and reproduction. Any disorder in the balance of these hormones directly affects a child's physical development, growth, and overall health. The Pediatric Endocrinology Department at Koru Hospital offers comprehensive solutions for children's hormonal health issues with its expert physicians.

What Does Pediatric Endocrinology Deal With?

Pediatric endocrinologists evaluate diseases of endocrine organs such as the pituitary, thyroid, adrenal glands, pancreas, gonads (ovaries and testes), and parathyroid glands. These specialists monitor a child's growth curve, detect hormonal imbalances, and implement appropriate treatment protocols. Unlike adult endocrinology, pediatric endocrinology also comprehensively evaluates growth and puberty processes.

Hormonal disorders can manifest in different ways at various ages in children. Ambiguous genitalia in the neonatal period, hypoglycemia attacks in infancy, growth retardation in school-age children, or early or delayed puberty in adolescence are just a few of the conditions that fall within the scope of pediatric endocrinology.

Common Pediatric Endocrine Diseases

Growth Disorders

Short stature is one of the most common reasons for referral to the pediatric endocrinology outpatient clinic. There can be many reasons for short stature:

• Growth hormone deficiency: A condition where the pituitary gland cannot produce a sufficient amount of growth hormone. With early diagnosis and growth hormone therapy, it is possible to help the child achieve height growth appropriate to their genetic potential.
• Familial short stature: A condition of remaining below the expected average height due to genetic structure.
• Constitutional growth and puberty delay: A clinical picture where growth slows down temporarily but returns to normal in later periods.
• Turner syndrome: A chromosomal anomaly seen in girls, characterized by short stature and delayed puberty.
• Short stature due to chronic diseases: Celiac disease, kidney diseases, and inflammatory bowel diseases can negatively affect growth.

Thyroid Diseases

Thyroid gland diseases are among the frequently encountered endocrine problems in childhood:

• Congenital hypothyroidism: A condition where the thyroid gland does not function sufficiently from birth. Early diagnosis through the newborn screening program can prevent negative effects on mental development.
• Hashimoto's thyroiditis: An autoimmune thyroid disease and the most common cause of goiter and hypothyroidism in children.
• Hyperthyroidism (Graves' disease): A condition where the thyroid gland is overactive. It manifests with palpitations, weight loss, nervousness, and eye symptoms.
• Thyroid nodules: Although rare in children, these are conditions that require careful evaluation.

Diabetes

Type 1 diabetes is the most important chronic endocrine disease of childhood. It develops as a result of the autoimmune destruction of insulin-producing beta cells in the pancreas. It may present in children with excessive thirst, frequent urination, weight loss, and fatigue. Early diagnosis and appropriate insulin therapy are life-saving.

• Type 1 diabetes management: Includes insulin therapy, blood glucose monitoring, nutritional planning, and exercise regulation.
• Type 2 diabetes: The incidence in children is increasing in parallel with the rise in obesity.
• Diabetic ketoacidosis: An urgent and life-threatening complication of diabetes. It requires rapid intervention.
• Insulin pump and continuous glucose monitoring systems: Advanced technologies used in modern diabetes management.

Puberty Disorders

• Precocious puberty: The onset of puberty symptoms before the age of 8 in girls and 9 in boys. If left untreated, it can lead to early bone maturation and a shorter final adult height.
• Delayed puberty: The absence of puberty symptoms by age 13 in girls and 14 in boys. Treatment is planned according to the underlying cause.
• Gynecomastia: Breast enlargement in boys; although usually temporary, it requires evaluation.

Adrenal Gland Diseases

• Congenital adrenal hyperplasia (CAH): A genetic disease that develops due to enzyme deficiency in the cortisol production of the adrenal glands. Early diagnosis can be made through the newborn screening program.
• Addison's disease: Adrenal insufficiency that manifests with fatigue, weight loss, and darkening of the skin color.
• Cushing's syndrome: A condition that develops as a result of excessive cortisol production. Weight gain, rounding of the face, and growth retardation are observed.

Other Endocrine Diseases

• Calcium and Vitamin D metabolism disorders: Conditions such as rickets, hypoparathyroidism, and hypercalcemia are evaluated.
• Obesity and metabolic syndrome: Hormonal and metabolic complications of childhood obesity are monitored.
• Disorders of sex development: Evaluation of ambiguous genitalia and differences in sex development is performed.
• Hypoglycemia: Investigation of the causes of low blood sugar attacks and planning of treatment.

Diagnostic Methods

Accurate diagnosis in the field of pediatric endocrinology requires a comprehensive evaluation process:

• Growth curve analysis: Monitoring the child's height and weight development on percentile curves forms the basis of the diagnosis.
• Hormonal tests: Measurement of hormone levels in blood and urine samples.
• Stimulation tests: Assessing hormone response by applying stimulation tests in cases of suspected growth hormone deficiency.
• Bone age assessment: Determining the level of bone maturation via wrist X-ray to predict growth potential.
• Imaging methods: Methods such as thyroid ultrasound, pituitary MRI, and adrenal CT are used.
• Genetic tests: Chromosome analysis, gene mutation research, and newborn screening tests are performed.

The Relationship Between Childhood Obesity and Endocrine

Childhood obesity is one of the most important public health problems of our time and is a condition that directly affects the endocrine system. Endocrine complications such as insulin resistance, Type 2 diabetes, precocious puberty, polycystic ovary syndrome, and metabolic syndrome are frequently seen in obese children. The pediatric endocrinologist investigates the hormonal causes of obesity, evaluates existing complications, and creates a treatment plan specific to the child.

In obese children, growth is usually accelerated, and bone age may be advanced. This can be confused with precocious puberty and requires careful evaluation. Distinguishing between endocrine-related obesity (hypothyroidism, Cushing's syndrome, growth hormone deficiency, genetic syndromes) and nutrition-related obesity determines the treatment approach. While endocrine-related obesity is usually accompanied by growth retardation, growth is preserved or accelerated in nutrition-related obesity.

Genetic and Rare Endocrine Diseases

Pediatric endocrinology also covers the management of endocrine components of certain rare genetic syndromes. Growth disorders, puberty anomalies, and metabolic problems frequently accompany genetic diseases such as Turner syndrome, Klinefelter syndrome, Prader-Willi syndrome, and Noonan syndrome. Long-term endocrinological follow-up of these patients is of great importance in terms of improving their quality of life. Through genetic counseling services, families are informed about the inheritance pattern of the disease and the risks in future pregnancies.

Treatment Approaches

In pediatric endocrinology, treatment is planned according to the type of disease and the child's individual characteristics:

• Hormone replacement therapy: The administration of the missing hormone from an external source. Growth hormone, thyroid hormone, and cortisol replacement are the most frequently applied treatments.
• Insulin therapy: Lifelong insulin use is required in Type 1 diabetes. Better glycemic control is achieved with modern insulin analogs and pump systems.
• GnRH analogs: Used in the treatment of precocious puberty to stop the puberty process and prevent the loss of final height.
• Nutrition and lifestyle regulation: In addition to medical treatment, diet and exercise planning are carried out for obesity, diabetes, and metabolic diseases.
• Multidisciplinary approach: Holistic treatment is offered with genetic counseling, psychological support, dietitian, and physical therapy services.

When Should You Take Your Child to a Pediatric Endocrinologist?

It is recommended to consult a pediatric endocrinologist in the following situations:

• If there is significant short stature or tallness compared to peers
• If a sudden slowing or stopping in growth rate is observed
• If puberty symptoms have started before the age of 8 in girls and 9 in boys
• If puberty symptoms have not started by the age of 13 in girls and 14 in boys
• If there is excessive thirst, frequent urination, and unexplained weight loss
• If swelling in the front of the neck (goiter) is noticed
• If excessive weight gain and growth retardation are observed together
• If ambiguous genitalia or genital area anomaly is detected in a newborn
• If there is a family history of endocrine disease

Diabetes Education and Quality of Life

For children and families diagnosed with Type 1 diabetes, comprehensive diabetes education is one of the cornerstones of treatment success. Detailed information is provided to the family and the child on topics such as insulin injection techniques, carbohydrate counting, recognizing symptoms of hypoglycemia and hyperglycemia, and diabetes management during school and sports activities. With modern diabetes technologies such as continuous glucose monitoring systems and insulin pumps, the child's daily quality of life can be significantly improved.
