The sex hormones -testosterone in male and estrogen in the female are blamed for these changes. The fluctuation in hormonal level leads to instability in thoughts and behavior in adolescents. But sex hormones are not the only hormones responsible for changes during adolescence. There are few other hormones that act in the background, let’s learn about them.

Hormones Other Than Sex Hormones


Endocrine system or glands secrete chemicals into blood called hormones. These chemicals are capable of influencing the control of heartbeat. The hormonal imbalance may lead to a variety of diseases and disorders . Hence, hormones are secreted as per the requirement of our body. Hormone secretion also takes place in animals as well as in plants and each of the hormones has a specific role to play.

Thyroxine is a hormone released by the thyroid gland. It is present in the front part of the neck. Insufficient secretion of thyroxine leads to swelling of the throat, a disease called goiter.



  • Insulin

Insulin is a hormone which controls the sugar level in our body. This hormone is secreted by the pancreas. If the pancreas does not produce enough insulin, the blood sugar level increases and leads to a condition called diabetes.
