Does alcohol stunt growth?

by   |   Jun 12, 2024

Alcohol is widely consumed in beverages, such as beer, wine, liquors, and spirits. We all know the potential dangers of alcoholic intoxication and hangovers, but it is not just confined to such short-term effects. During childhood and adolescence, when the body is still going through significant development, even the least seemingly harmless substances could impose long-lasting consequences. This is why the question of whether alcohol consumption could hinder the growth of children or not. Let’s join us to unveil the science behind this concern.

Key Factors Influencing Growth During Adolescence

Genetics

Genetic makeup sets the blueprint for determining an individual’s final height and overall growth. Since it is passed down from generation to generation, what is determined by genes is hard to change, including those related to growth patterns.

Nutrition

Besides genetics, nutrition plays an indispensable role in ensuring that the body absorbs enough nutrients like protein, vitamins, and minerals essential for well-rounded growth.

Physical Activity

Regular exercises enhance stamina and improve the immune system to help protect the body against infections and illnesses. Besides, weight-bearing activities add extra strength to the bones and joints, reducing the risks of fractures during the growth years.

Sleep

Adequate quality sleep is one of the most important factors that ensure the healthy release of growth hormones, which is imperative for not only physical but also emotional and cognitive well-being.

Health Conditions

Children facing chronic illnesses like cardiovascular diseases that require a consistent usage of medications spanning their lives less or more might experience stunted growth.

Role of Hormones in Growth

  • Growth Hormone (GH): Growth Hormone is produced in the pituitary gland located in the brain. This hormone is in charge of facilitating growth in almost all tissues and cells, including muscles and bones. The levels of growth hormone secretion are primarily driven by genetic predisposition, sleep patterns, nutrition, physical activities, and other lifestyle factors.
  • Insulin-like Growth Factor 1 (IGF-1): Under the influence of growth hormone, the liver produces insulin-like growth factor 1 (IGF-1). The IGF-1 contributes to the proliferation and multiplication of cartilage cells in the growth plates. During teenage years when the growth plates remain active, the new cartilage cells form a template for bone to grow.
  • Sex Hormones: Consists of estrogen and testosterone, two key players involved in growth processes. For example, sex hormones contribute to the development of secondary sexual characteristics and the closure of growth plates during puberty.

How Alcohol Interfere with Hormone Production and Regulation

Growth Hormone Secretion

During the deep sleep stages, the body releases the highest level of growth hormones. Alcohol suppresses the release of growth hormones by disrupting sleep patterns and interfering with the natural rhythms of the sleep-wake cycle. Such suppression could lead to the reduction of nighttime pulses of growth hormones.

Insulin-Like Growth Factor 1 (IGF-1)

Due to the decrease in growth hormone, the levels of IGF-1 also drop, resulting in impaired growth processes and subsequently stunted growth.

Sex Hormones

Alcohol is also one of the main factors disrupting the delicate balance of sex hormones in both males and females. The imbalance of estrogen and testosterone may result in abnormality in growth patterns.

How Alcohol Disrupts Growth: A Multifaceted Approach

Alcohol-induced Liver Diseases

Chronic consumption of alcohol severely damages the liver, which is responsible for metabolizing growth-related hormones. In other words, alcohol impairs the liver’s ability to process and metabolize hormones effectively, leading to hormonal imbalances that affect growth.

Besides, consuming alcohol in the long term could pose higher risks of fatty liver, alcoholic hepatitis, or cirrhosis. These health conditions deviate from the normal detoxification and conversion of hormones involved in growth and development.

Nutrient Absorption

Alcohol consumption throws a wrench in how your body gets nutrients from food, Not only irritating the lining of the small intestine, where most absorption occurs but drinking alcohol also messes with the enzymes that break down food for effective absorption. You can think of these enzymes as tiny keys to unlock the potential of what you eat. By hindering the production and activity of these enzymes, alcohol hinders all the vitamins, minerals, and proteins that should have been utilized for optimal growth.

This adds up to malnutrition and ultimately leads to the lack of nutrients needed for the whole body to function properly. If malnutrition remains unaddressed, it will result in a whole host of problems regarding not only physical but also intellectual and emotional well-being.

Bone Health

Alcohol could directly impact the activity of bone-forming cells called osteoblasts, which translates into a slower rate of bone formation and weakened bones. However, malnutrition is truly a nightmare for bone growth and health. Typically, deficiencies in vitamin D, Calcium, and protein – all the important building blocks, will make your bones brittle and more susceptible to fractures and osteoporosis. Not only does alcohol intervene in calcium intake, but it also facilitates calcium excretion through urine. These double effects gradually deplete calcium levels stored inside the body, leading to a decline in bone mineral density.

Brain Function

Drinking alcohol will severely affect the process of memory concentration, making it hard for children and teenagers to process and retain information. This will further confine their capabilities within the academic and professional realms.

Conclusion: Does Alcohol Stunt Growth?

After examining the evidence-based research about the relationship between alcohol consumption and growth, it is clear that alcohol has negative influences on multiple aspects of the child during their critical developmental stages. Though this article is geared toward the long-term effects of chronic consumption, parents should also be mindful of their children’s occasional and moderate use of alcohol. Imagine that alcohol is like a roadblock on the journey to achieve their full potential. Its impacts range from hormone balance, nutrient absorption, sleep patterns, and brain function. Therefore, it is necessary to educate them about the potential impacts of alcohol on their growth to make informed decisions regarding alcohol consumption.

Besides minimizing alcohol, prioritizing nutritious food choices, good sleep hygiene, and a healthy lifestyle will inevitably help with reaching the fullest growth potential. In the end, responsible decisions more or less pose relative consequences to the overall health, especially of children during adolescence and early adulthood.
