At a glance
Hormone Replacement Therapy (HRT) is a treatment that adds hormones to the body when the body no longer makes enough of them on its own. It is most often used to replace estrogen and progesterone in women whose levels drop sharply at menopause, but it is also used for other hormone deficiencies in both men and women.
When hormone levels fall, tissues throughout the body that depend on those hormones begin to change. Bones may thin, the lining of the vagina may dry out, body temperature regulation can become erratic, and mood can shift. HRT delivers hormones through tablets, patches, gels, injections, or implants so that blood levels return to a range the body recognises, easing those changes.
Medical Condition
HRT is prescribed when the body's own hormone production falls below what is needed for normal function, causing symptoms that affect daily life or long-term health. The underlying reason may be a natural life stage, a surgical procedure, or a medical condition affecting the glands that make hormones.
- Menopause and perimenopause (the transition years leading up to menopause): hot flushes, night sweats, mood changes, vaginal dryness, and sleep problems.
- Surgical menopause: sudden hormone loss after the ovaries are removed.
- Premature ovarian insufficiency (the ovaries stop working before age 40).
- Hypogonadism (the testes or ovaries do not produce enough sex hormones), whether from a genetic condition, injury, or disease.
- Gender-affirming hormone therapy for transgender and non-binary individuals.
- Osteoporosis (thinning of the bones) prevention in women at high risk when other treatments are not suitable.
- Hypopituitarism (the pituitary gland in the brain does not produce enough signalling hormones that tell other glands to work).
HRT is generally not recommended in certain situations, and a doctor will weigh the risks and benefits carefully before prescribing it.
- A personal history of hormone-sensitive cancers, such as breast or uterine cancer.
- Unexplained vaginal bleeding that has not yet been investigated.
- A history of blood clots in the veins (deep vein thrombosis) or lungs (pulmonary embolism), depending on the type of HRT considered.
- Active liver disease.
- Recent heart attack or stroke.
- Uncontrolled high blood pressure.
Risks & Complications
HRT is well-established and widely used, but like any hormonal treatment it carries risks that depend on the type of hormones used, the delivery method, the dose, and how long therapy continues.
- Breast tenderness, bloating, and nausea in the first few weeks of use.
- Irregular vaginal bleeding or spotting, especially in the early months.
- Headaches or migraine in people who are susceptible.
- Mood changes, including low mood or irritability during dose adjustments.
- Skin irritation at the site of a patch or gel application.
- Increased risk of blood clots in the veins with some forms of oral HRT. Transdermal (through-the-skin) forms carry a lower risk.
- A small increase in the risk of stroke with certain types and durations of HRT.
- A modest increase in the risk of breast cancer with combined estrogen-and-progestogen therapy used for several years. The risk appears to return toward baseline after stopping.
- A small increase in the risk of endometrial cancer (cancer of the uterine lining) if estrogen is used without progestogen in women who still have a uterus.
- Gallbladder disease is somewhat more common in people taking oral estrogen.
Preparation & Procedure
HRT does not require fasting or an overnight hospital stay, but preparation still involves several steps to make sure the right type and dose are chosen safely.
Before starting, a doctor will usually ask about personal and family medical history, particularly any history of cancer, blood clots, or heart disease. Smoking should be discussed honestly, because it changes the risk profile of some HRT types. Alcohol intake and any current medications, including blood thinners and herbal supplements, are also reviewed.
Several tests are typically run before prescribing HRT to establish a baseline and rule out contraindications (reasons the treatment would not be safe).
- Blood hormone levels, including FSH (follicle-stimulating hormone, a signal that shows whether the ovaries are still responding), LH (luteinising hormone), estrogen, and sometimes testosterone.
- Thyroid function tests, because thyroid problems can cause symptoms similar to menopause.
- Blood pressure measurement.
- A breast examination and, depending on age and risk, a mammogram (an X-ray of the breast tissue).
- A pelvic examination and, where indicated, a cervical smear (Pap smear).
- Bone density scan (DEXA scan) if osteoporosis is a concern.
- Blood tests for liver function and cholesterol, especially if oral HRT is being considered.
- Blood glucose, as hormonal changes can affect blood sugar regulation.
The procedure itself is the consultation and initiation visit rather than a single surgical act. The steps generally follow this order.
- The doctor reviews all test results and discusses symptoms in detail.
- The most suitable type of HRT is selected: estrogen-only, combined estrogen and progestogen, or testosterone, depending on the patient's anatomy and goals.
- The delivery form is chosen: daily tablet, weekly or twice-weekly skin patch, daily gel applied to the skin, vaginal ring or cream, subcutaneous (under-the-skin) implant, or injection.
- The starting dose is set, usually at the lowest level expected to relieve symptoms.
- The doctor explains how and when to use the chosen form, what to watch for, and when to return for a review.
- A follow-up appointment is booked, usually within three months, to assess the response and adjust the dose if needed.
Aftercare
HRT is an ongoing therapy rather than a one-time procedure, so aftercare is really about managing the treatment safely over time. Most people continue with normal daily activities from the first day, but regular monitoring is essential to catch any problems early and to reassess whether continuing HRT is still the right choice.
- A review appointment, usually at three months after starting, to check whether symptoms have improved and whether any side effects have appeared.
- Annual reviews thereafter, covering blood pressure, breast health, and a general reassessment of risks and benefits.
- Mammogram and bone density scans at intervals recommended by the doctor, based on age and risk.
- Patch or gel application sites should be rotated to avoid skin irritation; the skin should be clean and dry before applying.
- If implants were inserted, the next insertion is typically needed every few months. The doctor will monitor blood hormone levels to time this correctly.
- Any unusual bleeding, breast changes, leg pain or swelling, sudden chest pain, or changes in vision should be reported to a doctor promptly, as these can signal rare but serious complications.
- Lifestyle habits that support bone and heart health, such as weight-bearing exercise and not smoking, are encouraged alongside HRT rather than as a replacement.
- Duration of therapy is reviewed annually. Some people use HRT for a few years; others may continue longer under careful supervision. There is no single rule that fits everyone.
Cost & What Determines It
The cost of HRT varies widely because it is not a single event but a continuing therapy that may span years, with choices at every stage about the type of hormones, how they are delivered, and how often monitoring is needed.
- Type and combination of hormones: estrogen-only therapy differs in cost from combined estrogen-progestogen or testosterone therapy.
- Delivery method: implants inserted in a clinic cost more per session than daily gel or tablets, though the frequency of clinic visits differs.
- Hospital class and country: the same hormone formulation can differ greatly in price depending on whether it is dispensed at a public facility, a private clinic, or an internationally accredited hospital abroad.
- Diagnostic workup before starting: bone density scans, hormone panels, mammograms, and other baseline tests each add to the initial cost.
- Ongoing monitoring: blood tests and consultations repeated every few months over years contribute significantly to the total cost.
- Duration of therapy: a treatment plan spanning several years costs considerably more in total than one used for a shorter period.
- Management of side effects or complications: dose adjustments, additional consultations, or switching delivery methods add to the overall cost.
- Concurrent medications: drugs used to support bone health or manage cardiovascular risk alongside HRT are usually billed separately.
Hospital packages for HRT initiation typically include the first consultation, a standard set of baseline blood tests, and the first supply of the chosen hormone product. Follow-up consultations, specialised imaging such as bone density scans or mammograms, and ongoing prescriptions are usually billed as separate items outside the package.
BPJS Kesehatan and most Indonesian private insurance policies do not cover medical treatment received abroad, which means patients travelling overseas for HRT usually pay entirely out of pocket or rely on private international health insurance. Before travelling, asking the hospital for a written cost estimate that itemises the initial workup, the first treatment, and the expected monitoring schedule helps avoid unexpected bills. Ongoing therapy will also continue after the patient returns home, so understanding the local cost of maintaining the same regimen in Indonesia is equally worth planning for.
Frequently Asked Questions
How many sessions of Hormone Replacement Therapy will I need?
There is no fixed number of sessions because Hormone Replacement Therapy is ongoing, not a short course. Your doctor will review your hormone levels and symptoms at regular check-ups, usually every few months at first, and adjust the plan as your body responds. Some people stay on therapy for a few years, others for longer, depending on the reason they started.
How does Hormone Replacement Therapy feel, and are there side effects?
Most people notice changes gradually over the first few weeks, such as shifts in mood, energy, or sleep rather than anything sudden. Some experience mild side effects early on, like bloating, breast tenderness, or headaches, which often settle once the dose is balanced. Your doctor will monitor your response and can adjust the type or amount of hormones if side effects persist.
How soon will Hormone Replacement Therapy start working?
Many people notice some improvement in symptoms, such as hot flashes, low energy, or mood changes, within a few weeks of starting. Full benefit usually takes two to three months, because the body needs time to adjust to the new hormone levels. Your doctor may fine-tune the therapy during this period based on how you feel and follow-up blood test results.
How much does Hormone Replacement Therapy cost?
The cost depends on several factors specific to your situation, including the type of hormones prescribed, the form they come in (such as patches, gels, or tablets), how long treatment continues, and how frequently you need specialist consultations and blood tests to monitor progress. A written estimate from the hospital or clinic will give you the clearest picture of what to expect for your individual plan.
