How Do Hormones Affect Child Growth ?

Several factors like nutrition, genetics, environment, and notably hormones will influence child growth and development. These biochemical messengers play a significant role in regulating height, weight, muscle development, and even brain development. But how will hormones influence the growth and development of the child? 

Simply, growth is not just about getting taller, it’s a huge process regulated by a network of hormones that literally disturbs everything, right from physical development to brain function. We can say that hormones act more like a messenger, guiding a child’s body through critical stages of development. When the hormonal imbalance is not normal, your kid’s growth can be stunted, or delayed. So, let’s explore how these hormones shape a child’s growth journey. 

What are hormones? 

We can say hormones as signalling molecules, which rapidly send specific chemical messages throughout the body. Those hormones will travel via the tissue fluids, like the bloodstream, to trigger specific cells or tissues and exert their effects. Several types of hormones will be produced by the body. Almost all hormones will act on every cell, organ, and bodily process and function. Notably, hormones play a good role in regulating the growth and development, metabolism, cognition, hunger, and reproductive processes. This process is vital in normal development in kids. 

What actually affects the child’s growth?

A few teens will develop a lot more than their peers, which is known as precocious puberty, a few will develop much later than others of the same age, known as delayed puberty. Most of the time, kids and teens can’t grow as fast as their kids of the same age. In case you are short, you may have familial short stature. On the other hand, even short parents have short kids. Suppose your healthcare provider finds you are growing steadily and properly maturing at the appropriate age. In that case, you are expected to grow to the normal height, although there are chances for becoming shorter than average. 

Teens who have constitutional growth will delay growth at a normal rate when they are young, but when it comes to pubertal development, they will lag behind and also their growth will spurt until after most of their peers. Individuals who have constitutional growth delay are often referred to as ‘late bloomers.’ 

When a child has constitutional growth delay, a healthcare provider will take X-rays of the wrist and the healthcare provider will compare them with X-rays of what’s considered normal for the age. Also, teens with this condition will have bones that will look younger than what’s expected for their age. Those teens will lack growth, and they also keep on developing until they become an older adult. Usually, they will match with their peers by the time they are young adults. 

Teens may lack growth when they have hormonal imbalance like: 

• Not getting sufficient protein, calories, and also a few vital nutrients in their diet. 
• Having a prolonged medical condition like issues with kidneys, heart, lungs, and intestines. 
• Having sickle cell anemia 

What are growth disorders? 

Teens may experience growth issues for several reasons. Simply, our body makes some hormones and that will control the growth and development. Several diseases related to the endocrine system can disturb growth. 

Typically, endocrine glands will secrete hormones and that will travel throughout the body in the bloodstream. The hypothalamus, a part of the brain, controls the pituitary gland, which in turn releases some of the hormones that inhibit growth and sexual development. Estrogen and testosterone are crucial hormones that drive sexual development and function. 

Hypothyroidism can result in growth-related issues, because when the thyroid gland fails to make sufficient thyroid hormone, which is crucial for normal growth. Typically, a blood test will indicate low thyroid hormone levels. One of the most common causes of poor growth is genetics. 

The next most leading cause of short stature is dwarfism. In case an individual has dwarfism, bones and cartilage will fail to grow normally. In most cases of dwarfism, both hands and legs will be short and look out of proportion to the rest of the body. Simply act fast to avoid the potential complications in the future. 

What does it mean by hormonal imbalance in children? 

Hormones hold a huge responsibility in the overall health of children, especially the development, and this highlights that unusual functioning of any endocrine gland in the body can have dramatic implications. Most of the disorders associated with hormonal imbalance will affect individuals’ growth and sexual development. 

In case any one of the endocrine glands gets involved in this process, it will show abnormal functioning and secretes very high or too little hormones, which potentially affects the pubertal development. For instance, precocious puberty is when kids will attain puberty in the early periods of life, and some adults will get delayed puberty, both conditions are highly influenced by unusual hormone secretion. 

Simply, kids who are suffering from disorders due to hormonal imbalance need immediate hormonal imbalance treatment in Coimbatore from the pediatric endocrinologist. 

What are the symptoms of growth hormone deficiency? 

Various factors like kids’ age and the cause will greatly influence the signs of growth hormone deficiency. Kids who have poor overall growth rates, typically those kids will grow less than 2.5 inches in a year before the age of 4, less than 2 inches in a year between the age of 4 and 8, and less than 1.5 inches in a year before puberty. Few individuals will have short height with normal upper and lower body proportions. Even a few kids may experience a delay in the development of growth. 

Further, abnormalities may be present based on the cause of the growth hormone deficiency, and the common symptoms include: 

• Congenital abnormalities 
• Face defects like cleft lips  
• Issues with puberty like delayed puberty 
• Weight gain will be out of proportion to growth
• Central hypothyroidism

How to diagnose growth hormone deficiency? 

The common diagnostic methods include: 

• A health care provider will evaluate your growth criteria and previous medical history to identify the cause of slow growth 
• X-rays 
• Blood and other laboratory tests 
• Genetic testing at times 
• Magnetic resonance imaging
• Stimulation tests 

Growth hormone levels in the body vary greatly and are not so crucial as other hormone levels in finding why a child’s growth is delayed. So, typically, doctors will make the diagnosis based on a collection of information. 

Firstly, doctors will check an individual’s height and weight to plot the measurement on age-specific growth charts to find whether they are growing slowly or not. Further, they will suggest bone X-rays in the hand, which shows whether the bones are growing normally for the child’s age. Typically, short kids will have normal bone development for their age. Only those kids with growth hormone deficiency will possess delayed bone development. Also, this delayed bone growth can occur in other conditions such as hypothyroidism and delayed puberty. 

Even doctors will find it difficult to assess the growth hormone deficiency because the production fluctuates throughout the day. At times, the measurement of growth hormone levels is often not helpful. Instead, doctors will order blood tests to measure levels of other substances in the blood that are triggered by growth hormone deficiency. 

Further, laboratory tests are done to identify the other causes of poor growth. Even genetic testing will be done if healthcare providers suspect the kid has a specific syndrome, like Turner syndrome. In case children have no other cause of poor growth, but still their growth hormone levels remain low, typically doctors will do a stimulation test for boosting growth hormone. During the stimulation process, the medications will be given, then measuring the reason for their growth hormone deficiency for a couple of hours. 

How to treat growth hormone deficiency? 

Children will be injected with synthetic boosting growth hormone, usually this injection will be given once a day, but newer forms of boosting growth hormones are injected once a week. This kind of hormone will be given until the kid reaches an ideal height. Kids may grow up to 4 to 5 inches during the first year of treatment. 

Kids won’t face any side effects due to this hormone therapy, but only a few will experience mild swelling of the limbs that typically resolves quickly. Boosting growth hormones will also help in increasing the height in kids who are short but have normally functioning pituitary glands, but this brings more controversy. Few parents are considering short height as a disorder, most of the time, doctors will not approve boosting growth hormone in these children. Regardless of the cause of short height, boosting growth hormone will be effective only when given before the bones stop growing. 

How do hormones influence your child’s growth? 

Hormones are secreted by endocrine glands and circulate through the bloodstream to target organs, directing crucial biological processes. Hormones regulate everything, from cell growth, metabolism, and even puberty begins. Each hormone plays an important role in ensuring a child grows properly. 

Numerous hormones contribute to child growth, and each one plays a unique role, like:  

• Growth hormone: 

Typically, the pituitary gland produces the growth hormones, which are the primary driver of height and muscle growth. This stimulates the production of IGF-1, which helps with bone elongation and tissue growth. 

• Thyroid hormones: 

These hormones regulate metabolism, energy production, and bone development. Without proper thyroid function, kids may experience delayed growth and cognitive impairment. 

• Insulin: 

This is crucial for glucose metabolism, insulin also contributes to cellular growth and energy distribution, ensuring proper development. 

• Cortisol: 

Cortisol helps in reducing stress, but persistent high levels can cause growth hormone deficiency and delay development. 

Do lifestyle changes help in reversing hormonal imbalance? 

While hormones naturally regulate growth, lifestyle factors play a crucial role in reversing hormonal imbalance. 

• Nutrition: 

A nutritious diet rich in proteins, vitamins, and minerals will assist in healthy hormone production. Insufficient iron and iodine can disturb thyroid function and overall growth. 

• Sleep: 

During sleep, the growth hormone secretion will be at its peak. So bad sleep patterns can hinder physical development. 

• Physical activity: 

Consistent exercise will boost GH production, strengthen your bones, and maintain a healthy metabolism. 

• Stress management: 

High stress levels can increase cortisol, which will result in growth hormone deficiency. 

When to see a doctor? 

In case a child shows abnormal growth patterns, delayed puberty, or unusual weight gain or loss, reach out to the pediatric endocrinology doctor in Coimbatore, they may evaluate hormone levels and recommend treatments like hormone therapy, lifestyle changes, or medications. 

Final thoughts: 

In conclusion, we can say that hormones are the crucial component for child development and overall health. Right from growth hormones to thyroid hormones and insulin, each plays a specific role in development. Always remember that, balanced diet, sufficient sleep, and consistent exercise can assist in maintaining optimal hormone levels. In case concerns arise about a child’s development, consider getting medical advice, which plays a significant role in intervention and treatment.
