Endocrine Disorders And Glands

The Endocrine system is a powerful network of various glands. They have a great impact on other organ systems and their functions. The chemicals secreted by endocrine glands called hormones. Hormones can manipulate or change various cell activities in such a way that they can make us as tall as a tree and as short as a herb. Hence, hormone level needs to maintain at equilibrium.

“Too much of anything and too little of anything are always dangerous”. The term the hormone imbalance also explains the same.In the case of hormones, an excess of the hormone may lead to some diseases, too little hormone also causes disease. The endocrine glands itself has a feedback mechanism to counteract the hormone imbalance but sometimes it fails and leads to some disorders or diseases. Few of them are as follow:

Dwarfism

Growth hormone secreted by the pituitary gland is responsible for dwarfism or shortness. When pituitary produces an insufficient amount of growth hormone, it retards the height of an individual.

Acromegaly:

Acromegaly is also known as gigantism. It is also a growth hormone-related disorder. In contrast to dwarfism, gigantism is the outcome of the excess secretion of growth hormone by the pituitary.

Cretinism

It is an endocrine disorder caused due to deficiency of thyroid hormones. Cretinism is a type of hypothyroidism that occurs in infants or kids. It leads to mental and physical growth impairment.

Goiter

When the level of thyroid hormone is too high in blood, it shows symptoms like excess sweating, weight loss, etc. It also leads to the amplification (swelling) of the thyroid gland. This condition is known as goiter. It is either due to iodine deficiency or hyperthyroidism or hypothyroidism.

Graves’ disease

Also known as exophthalmic goiter- a type of hyperthyroidism. It is an autoimmune disorder which is commonly found in kids. In this condition, thyroid gland becomes overactive and secretes too much thyroid hormones.

Diabetes mellitus

The endocrine part of pancreas produces two hormones for the balancing blood glucose level; they are – glucagon and insulin. Diabetes mellitus, commonly known as diabetes is a condition in which blood glucose level is high due to insufficient secretion of insulin. Excessive thirst, weight loss, frequent urination are certain symptoms of the disease.

Addison’s disease

This is a condition which shows symptoms of extreme weakness and fatigue, dehydration, etc. Addison’s disease (adrenal insufficiency) is a hormonal disorder which explains the inefficiency of the adrenal cortex to produce its hormones like corticosteroids.

Here we had a glimpse of few endocrine disorders and conditions. For more details on endocrine glands download Byju’s-The Learning app.
