Hormones

Types of Hormones

Your body produces multiple types of hormones, each playing a specific role in maintaining overall health and wellbeing. The main types include:

• Thyroid hormones – control metabolism and energy production
• Sex hormones including oestrogen, progesterone, and testosterone – regulate reproductive health and secondary sexual characteristics
• Insulin – manages blood sugar levels
• Cortisol – regulates stress response and metabolism
• Growth hormone – influences body composition and development

When these hormones fluctuate or decline, various symptoms may occur, making treatment necessary to restore balance and improve quality of life.

Hormone Replacement Therapy for Women

Hormone replacement therapy (HRT) is commonly prescribed for women experiencing menopause or perimenopause symptoms. The transition typically occurs between ages 45 and 55 when oestrogen and progesterone levels decline naturally. HRT can significantly reduce hot flushes, night sweats, mood changes, and vaginal dryness that many women experience during this life stage.

Available HRT Products in Australia

Australian pharmacies stock various HRT options tailored to individual needs. Estradot patches deliver oestrogen transdermally and are available in different strengths to suit individual requirements. Premarin contains conjugated oestrogens derived from natural sources, whilst Divina combines oestradiol and medroxyprogesterone for cyclical dosing. Your doctor will determine the most appropriate formulation based on your symptoms, medical history, and individual circumstances.

Forms and Administration

HRT comes in multiple forms allowing patients to choose what works best for their lifestyle. Patches provide consistent hormone delivery and bypass the digestive system, making them suitable for women with certain medical conditions. Oral tablets are convenient for daily dosing, whilst vaginal preparations address localised symptoms like dryness and atrophy. This variety ensures that most women can find an HRT solution that fits their needs and preferences.

Thyroid Hormone Medications

Thyroid hormones regulate metabolism, energy levels, and body temperature. When the thyroid produces insufficient hormones, hypothyroidism develops, causing fatigue, weight gain, and cold sensitivity. Thyroid replacement therapy restores normal hormone levels and alleviates these symptoms. In Australia, levothyroxine is the standard first-line treatment for hypothyroidism, helping patients regain energy and maintain healthy weight.

Common Thyroid Medications Available

Levothyroxine sodium, marketed as Oroxine and generic equivalents, is the most frequently prescribed thyroid medication in Australia. Liothyronine sodium offers an alternative for patients who don’t respond adequately to levothyroxine alone. Some patients benefit from combination therapy using both T4 and T3 hormones. Your doctor will determine appropriate dosing based on blood tests measuring thyroid-stimulating hormone levels to ensure optimal treatment.

Managing Thyroid Treatment

Consistent daily dosing of thyroid medication is crucial for maintaining stable hormone levels. Taking medication on an empty stomach, typically in the morning, optimises absorption. Regular blood tests monitor TSH levels to ensure your dose remains appropriate. Certain foods, supplements, and medications can interfere with thyroid hormone absorption, so discuss all medications and supplements with your healthcare provider to prevent interactions.

Sex Hormones and Reproductive Health

Sex hormones including testosterone, oestrogen, and progesterone regulate reproductive function, sexual characteristics, and mood. In men, testosterone production typically declines after age 30, sometimes causing fatigue, reduced libido, and decreased muscle mass. In women, conditions like polycystic ovary syndrome (PCOS) involve abnormal hormone levels affecting fertility and metabolic health. Hormone treatments address these concerns and help restore hormonal balance for improved wellbeing.

Medications for Men

Testosterone replacement therapy comes in various formulations including injections, gels, patches, and pellets. TRT can improve energy levels, sexual function, and muscle mass in men with clinically confirmed low testosterone. Australian men can access testosterone undecanoate injections and testosterone gel preparations through their doctor. Treatment requires regular monitoring to ensure hormone levels remain within normal ranges and to assess treatment effectiveness and tolerability.

Women’s Reproductive Hormones

Oral contraceptives containing oestrogen and progesterone regulate menstrual cycles and prevent pregnancy. Beyond contraception, they help manage PCOS, endometriosis, and heavy periods. Australian pharmacies stock numerous brands including Microgynon, Yasmin, and Yaz, each with different hormone concentrations and compositions. Progestin-only pills offer alternatives for women who cannot tolerate oestrogen, ensuring effective options for all patients.

Insulin and Blood Sugar Management

Insulin is a hormone produced by the pancreas that regulates blood sugar levels. Type 1 diabetes occurs when the pancreas produces little or no insulin, requiring insulin replacement therapy. Type 2 diabetes involves insulin resistance, sometimes requiring insulin supplementation alongside other medications. Proper insulin management prevents serious complications and maintains stable energy levels throughout the day.

Insulin Products in Australia

Australian diabetes patients can access multiple insulin types designed for different needs. NovoRapid and Humalog provide rapid insulin action for mealtime coverage, whilst Lantus and Levemir offer long-acting basal coverage. Premixed insulins combine rapid and intermediate actions for convenience, and insulin pens and pumps deliver medication precisely. Traditional syringes remain available for those who prefer them. Your endocrinologist will recommend appropriate insulin regimens based on your lifestyle and blood sugar patterns.

Blood Sugar Monitoring

Regular blood sugar testing helps determine correct insulin doses and treatment effectiveness. Continuous glucose monitors provide real-time blood sugar data, improving management outcomes significantly. Maintaining consistent meal timing, exercise routines, and stress levels helps stabilise blood sugar alongside insulin therapy. Healthcare providers adjust insulin doses based on monitoring results to achieve optimal control and prevent complications.

Adrenal and Other Hormonal Disorders

The adrenal glands produce cortisol, adrenaline, and other hormones essential for stress response and metabolism. Adrenal insufficiency occurs when the adrenal glands don’t produce adequate hormones, causing fatigue, weakness, and low blood pressure. Corticosteroid replacement therapy restores hormonal balance. Additionally, other hormonal conditions including growth hormone deficiency and hyperprolactinaemia require specific hormone treatments from specialist healthcare providers.

Adrenal Hormone Treatment

Hydrocortisone tablets provide cortisol replacement for patients with adrenal insufficiency, restoring energy and blood pressure regulation. Prednisolone offers an alternative corticosteroid option for various conditions. Fludrocortisone helps manage mineralocorticoid deficiency affecting sodium and blood pressure regulation. Proper dosing prevents both under and over-treatment complications. Patients learn to adjust doses during illness or stress when hormone demands increase, ensuring consistent wellbeing.

Other Hormonal Conditions

Growth hormone replacement helps adults with growth hormone deficiency improve body composition and quality of life. Bromocriptine and cabergoline treat hyperprolactinaemia by reducing prolactin levels effectively. Hormone treatments for these conditions require specialist oversight and regular monitoring to ensure optimal outcomes. Your doctor will determine appropriate treatment based on hormone level testing and symptom assessment, ensuring you receive comprehensive care for your specific hormonal condition. Australian pharmacies stock these medications under professional guidance to help patients manage their hormonal health effectively.
