Hormones and Your Health: An Essential Guide
Despite the common perception that hormones only have a role in our bodies and thoughts at specific stages of life, like puberty, pregnancy, and menopause, this is far from the truth.
So, what are hormones, exactly? Chemicals called hormones circulate in the body. They are messengers that provide information from the glands that make them to the cells throughout the body. These chemical messengers aid in managing cellular functions, including hunger, growth, blood sugar, stress, sex drive, sleep cycles, and sexual function.
The Role of Hormones
Hormonal has become a synonym for emotional. Hormones do more than just influence mood in the body.
Hormones have a role in everything from the most fundamental (such as hunger and heart rate) to the most intricate aspects of human biology (reproduction and emotion).
In addition to their hormonal roles, certain hormones (including serotonin and dopamine) act as neurotransmitters, molecules that transfer signals between neurons and neurons and muscle cells. Simply put, neurotransmitters regulate our emotions, thoughts, and motor skills.
The Endocrine System's Glands are the Source of the Body's Hormones. The body's main hormone-secreting glands are the pituitary gland, the hypothalamus, the thymus, the adrenal glands, the pancreas, the thyroid, the ovaries, and the testes. The endocrine system is the network of hormone-secreting glands and organs in the body.
Health Issues Caused by Hormonal Imbalances: Diagnosis & Treatment
Given their crucial role in maintaining health, even mild disruptions in hormone balance can have far-reaching effects. It can be challenging to determine whether more or less of a particular hormone is needed, and treating a hormone imbalance often requires more than that.
There are several interconnected parts of the endocrine system. We have yet to fully understand how hormones interact with one another or the immune system, among many other physiological systems. We look at some essential hormones and the many roles that have been discovered for them in the human body.
To fully develop, a woman's reproductive system requires estrogen, which is produced mainly in the ovaries. Estrogen (a group of hormones mostly made up of estrone, estradiol, and estriol) regulates the menstrual cycle throughout a woman's fertile years. The adrenal glands and adipose (fatty) tissue release a tiny amount of estrogen. Estrogen is a crucial hormone for men and women because of its function in maintaining bone health. The male body produces it by converting testosterone into estradiol.
Estrogen influences metabolic processes, including cholesterol regulation, and impacts the brain, liver, heart, and skin health.
Androgens like testosterone are crucial during adolescence in males. Many of the physical traits we associate with men are produced by the hormone testosterone. This includes face and body hair, muscular bulk, and a deep voice.
The testicles produces testosterone, which belongs to the family of hormones known as androgens. Of course, testosterone isn't limited to males. Female adrenal glands and ovaries produce minuscule quantities of testosterone. Ovarian function, bone strength, and potential sex desire are all affected by testosterone in women.
Testosterone levels naturally fall with age in both sexes. Low levels of testosterone have been linked to diminished libido in postmenopausal women. Decreased testosterone levels, commonly called "low T," have been linked in males to various health issues, including weakened bones and muscles, trouble sleeping, and difficulty achieving and sustaining an erection.
Testosterone replacement treatment (TRT) is sought by some men experiencing similar symptoms; however, its long-term consequences are not well-established.
Cortisol, the "Stress Hormone"
The stress hormone cortisol plays an essential role in coping with pressure. Cortisol levels rise in response to stress, giving you energy while also earning it the "stress hormone."
Cortisol is essential because it regulates the metabolic processes that turn proteins, lipids, and carbohydrates into usable fuel.
The adrenals are a pair of triangle glands that secrete the hormone cortisol into circulation. Each kidney has an adrenal gland perched above it. Excess or deficiency of cortisol over time can have detrimental effects on health.
In recent years, "adrenal fatigue" has become a popular buzzword, especially among healthcare professionals marketing medicines that claim to alleviate symptoms, including exhaustion, muscle pain, anxiety, and digestive issues.
The hormone serotonin also acts as a neurotransmitter. Serotonin is sometimes referred to as the "happy chemical" because of its apparent function in mood regulation and the correlation between low serotonin levels in the brain and poor mental health.
Serotonin is crucial for proper brain function and the health of many other bodily systems. It promotes healthy eating, digestion, bone growth, and sexual function. Melatonin regulates the body's sleep-wake cycle and can only be made with serotonin first.
Serotonin is a neurotransmitter that the brain makes. Scientists have recently discovered that serotonin is produced by the intestines, especially the gut bacteria that line them.
The hormone and neurotransmitter dopamine play a crucial role in regulating and coordinating bodily activity. Because of this, several medications for Parkinson's disease (a movement illness) aim to increase brain dopamine levels.
Dopamine neurotransmitter plays a crucial role in the brain's reward system, producing pleasurable states. Some illicit substances can achieve this by binding to and activating the brain's reward system, known as dopamine receptors.
Dopamine is engaged in several non-cognitive tasks outside the brain. It helps dilate blood vessels, stimulates urination, and lowers pancreatic insulin secretion, which impacts blood sugar levels.
The Pregnancy Hormone, Progesterone
Progesterone is a crucial hormone for women attempting to conceive because it helps them prepare their bodies for pregnancy. Since the uterus is prepared to receive and develop a fertilized egg, progesterone is crucial to the initiation and maintenance of pregnancy.
In addition to the ovaries, the placenta contributes to a woman's progesterone production when pregnant. High quantities of the hormone are secreted by the placenta during pregnancy, preventing ovulation and getting the breasts ready to give milk.
Most non-hormonal contraception forms aim to prevent fertilization by preventing sperm from reaching the egg (s). Contraceptives that use hormones change the normal functioning of a woman's body. A woman's chances of ovulation, embryo formation, and successful implantation are diminished when using hormonally-based procedures.
Usually, estrogen, progestin (a synthetic version of progesterone), or a mixture of the two hormones is used in hormonal birth control. Pills for once-a-day usage are one option, while hormonal IUDs can prevent pregnancy for several years.
