How much does it grow per year?

Growth speed graph by year according to age – up to 19 years. Reference: (1)

Body growth in children 2-3 years old is the most active; statistics show up to 40 mm per year. After that, the increase in growth slows down a bit, averaging up to 5-6 mm per year between 4-11. (2)

In adolescents, the fastest growth peak is between 11 and 12 years old. Once they develop, they begin to grow around 2.5 to 5 cm. After 15 – 16 years, this figure gradually decreases. The processes continue until the age of 18-19, and the increased growth stops.

The hormone growth hormone is mainly affecting the development of the tissues of the body. The level of this hormone is highest in children and is high in adolescence, and after 35-40 years, it begins to decrease at a rate of 15-17% per decade.

Factors that affect your height

Around 60-80% of growth factors are at the genetic level, while the remaining 20-40% are determined by diet and lifestyle. In particular, adequate protein, calcium, and vitamin D directly affect growth.

Excluding the negative factors that reduce growth: nutritional deficiencies, bad habits, recurrent infections, and a sedentary lifestyle will contribute to the total number that a person can grow per year.

This is especially important in adolescence when the body is in the growth phase. However, it is essential to know that when it comes to growth, it is necessary to cover an adequate amount of these nutrients: an excess of calcium not only does not help to increase growth, but it can have undesirable consequences for health. Factors affecting growth:

  • Genetics
  • Nutrition
  • Physical exercise
  • Sex
  • Hormones
  • Some medical conditions
