Introduction to Houston Pediatric Endocrinology

Our experienced Houston Pediatric Endocrinologist Dr. Deepa Suresh can manage your child's endocrine conditions. The endocrine system controls reproductions, development, growth, and maintains the internal environment. Originally the endocrine system was thought to regulate metabolism via biochemical messengers (hormones) that were released from specialized organs (glands) into the general blood circulation so they could act at a far away distance from where they originated. Therefore hormones were thought to be circulating messengers the the location of their action far away from their site of production.  Hormone action can be paracrine (acting on an adjacent neighboring cells) or autocrine (acting on cell of origin by diffusion). 

In the past, most of the endocrine glands seemed to be controlled by the pituitary gland. Therefore, the pituitary gland was considered the "master gland." The part of the brain call the hypothalamus also has some control over the pituitary. There is an overlap between the control of the endocrine system and the nervous system.

Hormones are often regulated in a feedback loop, so that the production of a hormone is controlled by it's effect. There is a set point of the equilibrium between the feedback loop hormones, which may change with development. In pre-puberty small amounts of sex steroids (like estrogen) suppress the gonadotropins (like LH and FSH), but during pubertal development, the sensitivity of this feedback loop decreases. Thus increased sex steroid production that causes the subsequent physical changes of puberty occur without the sex steroids suppressing pituitary control as would happen in a pre-pubertal state. A pediatric endocrinologist may figure out the level of an endocrine defect in the system after measuring serum concentrations of the hormones at different steps of the expected processes.
