Endocrinology

The endocrine system comprises all the endocrine glands in our body—namely, glands capable of producing hormones. Hormones are biochemical substances that carry a signal through the bloodstream from one cell to another cell, tissue, or organ, in order to trigger a specific functional response.
The endocrine system is fundamentally important throughout our entire lives: it regulates growth, metabolism, sexual development, digestion, mood, stress response, and the sleep-wake cycle.
The major endocrine glands are:

• the hypothalamus – it secretes the hormones required to interact with and stimulate the adjacent pituitary gland. It is situated below the thalamus;
• the pituitary gland– of paramount importance as, stimulated by the hypothalamus, it secretes 9 distinct hormones: growth hormone, thyrotropin, adrenocorticotropin, prolactin, gonadotropins, melanotropin, oxytocin, and antidiuretic hormone;
• the thyroid gland– located at the base of the neck, it produces 3 hormones: thyroxine, triiodothyronine, and calcitonin;
• the pineal gland – it secretes melatonin, which regulates the circadian sleep-wake cycle;
• the pancreas – an integral part of the digestive system that secretes the hormones insulin, glucagon, and pancreatic polypeptide;
• the adrenal glands – located superior to the kidneys, they are responsible for secreting adrenaline, cortisol, noradrenaline, and aldosterone;
• the gonads – corresponding to the ovaries in females and the testes in males, they produce gametes and sex hormones.

Through a painless, non-invasive endocrinological consultation, it is possible to identify, evaluate, and promptly manage issues related to potential hormonal imbalances.
Indeed, endocrinology addresses all types of hormonal disorders, including:

• diabetes mellitus – a metabolic disorder caused by a decrease in the activity or production of the hormone insulin, synthesized by the pancreas;
• growth disorders – dwarfism and gigantism represent the two main categories of growth-related pathologies; the former describes statural growth deficits, while the latter involves excessive statural development;
• thyroid diseases – the most common and well-known include hypothyroidism, hyperthyroidism, thyroiditis, thyroid nodules, and goiter;
• infertility issues due to hypogonadism – hypogonadism denotes reduced functional activity of the gonads, which are tasked with producing gametes and sex hormones;
• menopausal disorders – menopause is a physiological condition marked by profound hormonal fluctuations; an endocrinological assessment is recommended both for severe symptoms and in cases of premature menopause (occurring before the age of 40);
• precocious or early puberty – defined as precocious puberty when secondary sexual characteristics develop before age 9 in boys and age 8 in girls;
• dyslipidemia disorders – lipid profile abnormalities can lead to elevated blood cortisol levels, an essential component in steroid hormone synthesis.

Many other pathologies can be promptly diagnosed and managed through an endocrinological consultation.
