Dear Yi-En,
Hello, smoking hinders the gastrointestinal absorption of nutrients, and the nicotine in cigarettes also reduces appetite.
Additionally, smoking is associated with the occurrence of many cancers.
Therefore, quitting smoking before puberty is crucial for development and growth.
If you truly want to grow taller, you should make the decision to quit smoking and maintain a regular lifestyle, avoid staying up late, and ensure a balanced diet.
Engage in at least three sessions of jumping exercises each week, such as jumping rope or playing basketball.
If you find it difficult to quit smoking on your own, many hospitals offer smoking cessation clinics or have smoking cessation educators available to assist you.

Wishing you all the best in achieving your goals and growing tall and handsome!
Sincerely,
Dietitian Shih Kuei-Mei

At 14 years old, your body is still in a critical phase of growth and development. It's understandable to be concerned about height, especially when comparing yourself to peers. The question of whether smoking can stunt growth is significant, and the answer is a resounding yes. Smoking, particularly during adolescence, can have detrimental effects on your growth potential.

Firstly, smoking introduces harmful substances into your body, including nicotine, which can affect your appetite and the absorption of essential nutrients. Adolescence is a time when your body requires a variety of nutrients to support growth, including proteins, vitamins, and minerals. Smoking can lead to decreased appetite, which may result in inadequate nutrition. This lack of proper nutrition can hinder your growth and overall development.

Moreover, studies have shown that smoking can negatively impact bone health. Nicotine affects the production of hormones that are crucial for bone growth and density. This can lead to weaker bones and potentially stunt growth during these formative years. Additionally, smoking can lead to respiratory issues, which can affect your physical activity levels. Regular exercise is vital for promoting healthy growth, and if smoking limits your ability to engage in physical activities, it could further impact your height.

Regarding your family background, genetics plays a significant role in determining your height. The average height of your parents can give you a rough estimate of your potential adult height, but it is not the only factor. The formula often used is to take the average of your parents' heights and adjust for gender. For example, if your father is shorter than average and your mother is 158 cm, your potential height may be influenced by these factors. However, it is essential to remember that many other factors, including nutrition, physical activity, and overall health, can also play a role in your growth.

To maximize your growth potential, consider the following recommendations:
1. Quit Smoking: If you are currently smoking, it is crucial to stop. Seek support from healthcare professionals or smoking cessation programs. Quitting smoking will not only improve your overall health but also enhance your growth potential.

2. Nutrition: Focus on a balanced diet rich in fruits, vegetables, lean proteins, and whole grains. Ensure you are getting enough calcium and vitamin D, which are essential for bone health. Foods like dairy products, leafy greens, and fish can help support your growth.

3. Physical Activity: Engage in regular physical activities, especially those that promote stretching and strengthening, such as swimming, basketball, or jumping rope. Aim for at least 60 minutes of exercise most days of the week.

4. Sleep: Ensure you are getting adequate sleep. Growth hormone is primarily released during sleep, so maintaining a regular sleep schedule and getting enough rest is vital for growth.

5. Consult a Healthcare Professional: If you have concerns about your growth or overall health, consider consulting a pediatrician or an endocrinologist. They can assess your growth patterns, possibly perform a bone age test, and provide personalized advice.

In conclusion, smoking can indeed stunt growth, and it is essential to prioritize your health during these crucial years. By making positive lifestyle choices, you can enhance your growth potential and overall well-being. Remember, height is just one aspect of who you are, and focusing on your health and self-esteem is equally important.
