Hormones and Hormaonal Disorders

Adolescence commences with lots of changes, marking the transition from childhood to adulthood. This may include physical, emotional, social, and behavioral changes. 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.

Hormonal Disorders:

Hormones are very particular about their action; they act only on their specific target site. Visit endocrine glands and hormones to know more about endocrine gland and all the different hormones in detail. Some of the important hormones secreted by different endocrine glands and disorders caused by their imbalance are as follows.

  • Thyroxine

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.



  • Adrenaline

Adrenaline is released from a pair of adrenal glands present at the top of kidneys. Adrenaline is known as “fight-flight hormone”. It is the hormone of emergency. It also helps to balance the salt level in the blood.

Among these, thyroxine and adrenaline are released as per the signal sent from the master gland called pituitary gland. It is located in the brain. This gland secretes the growth hormone. The growth hormone controls the body growth viz. how tall or short you should be.
