Children go through a complicated transitional period known as puberty, which is characterised by the development of secondary sexual traits and an acceleration of growth. It is a stage of both psychological and physical growth. Nonetheless, some children do occasionally experience early puberty. The term “precocious puberty” is used to describe this early puberty. The onset and course of early puberty are significantly influenced by several genetic, environmental, and nutritional variables. Since early puberty can be psychologically distressing for both parents and children, this article covers all the essential characteristics of early puberty in girls.
What is considered early puberty in girls?
The term puberty refers to a critical phase during which your child experiences a growth spurt and acquires adult-like physical and sexual characteristics. This onset of adulthood is marked when the hypothalamus in your child’s brain produces chemicals called hormones that trigger the pituitary gland to release gonadotropin hormones. Gonadotropins stimulate the ovaries, also referred to as the gonads, causing the release of oestrogen.
Since puberty in girls usually starts between the ages of 8 and 13, the ones with early puberty undergo this process much earlier. Hence, the development of secondary sexual characteristics before 8 years of age in girls is known as precocious puberty.
Why do girls go through early or precocious puberty?
As previously stated, the hypothalamus normally initiates puberty. This part of the brain sends signals to the pituitary gland, a pea-sized gland located near the base of the brain, stimulating the production of sex hormones in the ovaries of the girls.
Puberty that comes on too soon is usually just an accelerated version of the normal process; in other words, it’s like a biological alarm that goes off too soon because the clock is running faster.
Puberty can sometimes begin early due to abnormalities in the pituitary gland or the hypothalamus, the area of the brain that regulates the pituitary. The term “true precocious puberty,” or “central precocious puberty,” refers to this type of early puberty. This sort of early puberty is indicative of true pubertal development because of the early activation and maturity of the HPG axis.
Peripheral precocious puberty, or PPP, is defined as the premature development of secondary sexual traits independent of the pulsatile secretion of GnRH; this is caused by the endogenous or exogenous synthesis of sex hormones. The exogenous sources include both environmental and nutritional variables.
In females, idiopathic causes account for the majority of cases. This could be attributed to the transmission of brain signals earlier than it should. While there are no reported medical conditions or triggers, this frequently runs in families.
Precocious puberty is less frequently caused by a more serious issue, like a tumour or trauma. Ovarian or thyroid issues may also be the cause of early puberty. Additional symptoms usually show up in these circumstances, indicating a more serious issue.
Premature adrenarche, a condition in which body odour and pubic and/or axillary hair appear before the age of eight, is brought on by the adrenal glands, tiny glands positioned on top of the kidneys. This might affect both males and females and does not require any therapy.
Furthermore, early puberty may result from using prescribed or over-the-counter creams or medications that contain oestrogen or androgen.
When should parents consult their doctor?
Parents should speak with a doctor if their child exhibits any of the symptoms of early sexual maturation, such as breast development, rapid height growth, menstruation, acne, or a combination of these.
When you visit the doctor because you are concerned about your child reaching puberty too early, apart from looking over the growth chart and having your child examined, there may be additional tests carried out. These tests may include:
- Blood work to measure the levels of oestradiol and pituitary hormones such as luteinizing hormone, or LH, and follicle-stimulating hormone, or FSH, which regulate puberty. Before measuring these hormones, the doctor might inject your child with leuprolide, a synthetic hormone, to assist in obtaining an easier-to-interpret result.
- Bone age, also known as an x-ray of the left hand and wrist, may be taken to gain a better picture of how far along puberty is, how quickly it is proceeding, and how it may affect your child’s height as an adult.
- If your child’s blood tests indicate that they have CPP, a brain MRI may be performed to rule out any underlying abnormalities in the pituitary gland region.
How is precocious puberty medically addressed?
Early puberty in girls is handled in accordance with the type of precocious puberty:
Managing true precocious puberty (CPP): If treatment is necessary, it will depend on the child’s age and the stage of puberty they are approaching. Treatment should be considered if the child’s symptoms are getting worse quickly or if their bone age is noticeably advanced. The primary objectives of therapy are to preserve adult height and lessen the associated psychosocial stress.
The standard treatment protocol involves the administration of GnRH agonists. GnRH agonists, both long- and short-acting, are available for subcutaneous, intramuscular, and inhalation administration. The patient’s and the practitioner’s preferences determine which formulation should be employed.
Addressing precocious puberty with GnRH agonists is usually regarded as safe, and no notable adverse outcomes have been documented. The most common side effects are postmenopausal symptoms like hot flushes and local skin reactions, including intramuscular discomfort and sterile abscesses.
While undergoing therapy, periodic evaluation of pubertal advancement, growth velocity, and skeletal maturation is essential.
Taking Care of Early Puberty from External Sources (PPP): Eliminating the Sex Steroid Source is the ultimate goal of treatment for PPP. Therefore, it is necessary to identify and swiftly eliminate the exogenous or external sources of sex steroids in order to correct PPP.
Prompt management can potentially decrease a girl’s breast size, slow down her height growth to a level normal for prepubescent children, and most importantly, help her behave more appropriately for her age.
What is the impact of unaddressed precocious puberty on children?
The completion of puberty marks the final stage of height growth. Children with untreated premature puberty usually fall short of their adult height potential because their skeletons mature and bone development ceases earlier than usual. Compared to their peers, they may initially be taller due to their early growth spurt. However, they might reach a shorter height than they otherwise would have if they stop growing too soon.
Early puberty can also be socially and psychologically challenging for children. For instance, girls who experience early puberty may feel perplexed or embarrassed about getting their periods early or developing larger breasts before any of their friends. Their appearance might also influence their treatment.
Girls who experience precocious puberty may exhibit grumpy and irritable behaviour due to emotional changes brought on by early hormone play. Hence, parents should seek professional medical support.
The value of parental support:
Explain the situation to your child in a forthright and honest manner. Inform them that their body developed a little too early, even if these changes are normal for young children and teenagers. Let your child know about the treatment process and what to anticipate at every stage of the procedure.
Keep an eye out for indicators that your child’s emotional health may be being negatively impacted by teasing or other issues. Consult your doctor about common warning symptoms such as depression, lack of enthusiasm in academics, loss of interest in daily activities, and difficulties in school.
Fostering a positive self-image and high self-esteem is another way parents may actively help their child cope with early puberty. This can be accomplished by encouraging your child’s interests and praising them for their accomplishments in sports or academics.
Please be mindful that although medical professionals may be able to cure early puberty, prevent children from reaching premature adult height, and lessen the emotional and social pressures associated with early maturation, a child still requires psychological care from their parents.
