Endocrine system

The endocrine system plays a crucial role in important functions such as digestion, reproduction and homeostasis (constant internal balance). The endocrine system is primarily made up of the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body and the reproductive glands. The endocrine secretions work along with the immune system and the nervous system to aid the body in various situations. Endocrine glands secrete major hormones directly into the bloodstream. This is then carried to all parts of the body.

• The hypothalamus is the hub for the endocrine and nervous systems. It controls the functioning of the pituitary gland.
  
• The pituitary secretions exercise control over other endocrine glands. Some of the important hormones secreted by the pituitary are the growth hormone, prolactin, corticotropin, endorphin and thyrotropin.
  
• The thyroid hormones are vial to the development of brain and nervous system in children.
  

Endocrine disorder

Endocrine system disorders occur either due to too much or too little or sometimes no hormone. These disorders may lead to abnormal growth pattern, osteoporosis, diabetes, high cholesterol and triglyceride levels and thyroid malfunction. Endocrine system disorders include hyperthyroidism, hypercalcemia, growth hormone deficiency, Addison\\\'s disease, Cushing\\\'s Syndrome and hypothyroidism. Endocrine disorders can be triggered by tumors, steroid medications or autoimmune problems. A person suffering from a disorder caused by any of the malfunctioning endocrine glands may notice change in weight, change in libido, mood swings, increased fatigue and thirst or urination. Endocrine disorders are caused due to malfunctioning endocrine glands. In some cases, the gland produces in excess while in others there is insufficient activity of the gland. Inadequate secretion of endocrine glands (hypofunction) can be attributed to malformations or disease or injury. Excessive production of hormones (hyperfunction) is usually caused by glandular tumors or auto immune reactions. Endocrine disorders are treated with hormone replacement in cases of inadequate production. In cases of excessive production of hormones, the abnormal gland tissues are removed.
