Endocrinology is a science that studies the structure and functions of the glands with internal secretion (which lacking the excretory canal send their secretion product-hormones directly into the bloodstream).

These glands are: pituitary, thyroid, parathyroids, epiphysis, suprarenal glands, pancreas and genital glands (ovaries and testicles).

Endocrinology deals with diseases affecting these glands and their treatment.

The thyroid is one of the most important glands of the body. When the thyroid doesn't work properly:

  • may issue too little thyroid hormone - hypothyroidism. How it manifest?
    • fatigue
    • low body temperature
    • Obesity
    • dry skin, dry and thin hair, hair loss
    • edema
    • low heart rate
    • constipation
    • problems with both distant attention
    • hoarseness
    • menstrual cycle disorders
    • infertility
    • goiter (increasing the volume of the thyroid gland)
  • may release too much thyroid hormone - hyperthyroidism. How it manifest?
    • nervousness/irritability
    • weight loss
    • fast/irregular pulse
    • changes in appetite
    • insomnia
    • tremor of the hands
    • shorter and heavier period with low flow
    • exophthalmos
    • goiter (increasing the volume of the thyroid gland)
  • glandular tissue can grow excessively, causing the appearance of lumps, small gland at sweelings.

Many people, especially women, suffer from diseases of the thyroid gland. They can be detected by a visit to the endocrinologist by clinical examination, echographic exam and laboratory tests.
