Puberty is a natural stage of life when a child's body begins to mature into that of an adult. It involves physical, hormonal, and emotional changes. For girls, puberty typically starts between the ages of 8–13 years, while for boys it usually begins between 9–14 years. When these changes occur much later than expected, it's known as delayed puberty.

What is Delayed Puberty?

Delayed puberty is when a child shows no signs of puberty by the expected age:

Girls: No breast development by age 13 or no menstrual period by age 15.

Boys: No testicular enlargement by age 14.

Possible Causes

Several factors can cause delayed puberty, including:

1. Constitutional Delay

o A common and harmless cause.

o Puberty starts later but progresses normally.

o Often runs in families.

2. Chronic Medical Conditions

Diabetes, kidney disease, inflammatory bowel disease, and other long- term illnesses can affect growth and hormonal changes.

3. Hormonal Disorders

Problems with the pituitary gland, hypothalamus, or thyroid can delay puberty.

4. Genetic Conditions

Turner syndrome, Kallmann syndrome, or other genetic disorders may be involved.

5. Poor Nutrition or Low Body Weight

Eating disorders or excessive physical activity can slow puberty onset.
