15660 Bioidentical Hormones

Overview

Bioidentical hormones are hormones made to be chemically identical to the hormones your body makes on its own, such as oestrogen and progesterone. They come in two main forms. The first are licensed products made by mainstream drug companies, with standard doses and official safety checks. The second are 'compounded' products, mixed up by a special pharmacy for one person, often as creams, gels or capsules, sometimes based on saliva or blood tests. Both types are used mostly to ease symptoms of the menopause, such as hot flushes and night sweats. The word 'bioidentical' may sound like it means safer or more natural, but that is not automatically true — what matters is whether a product has been properly tested, licensed and monitored.

Menopause symptoms are extremely common, and many people consider hormone treatment at some point. Compounded bioidentical hormones are much less common and are not recommended as a first choice by mainstream medical guidance. Interest in them has grown, partly because of marketing that describes them as 'natural' or 'customised'.

This topic mostly affects women going through perimenopause (the run-up to the menopause) and menopause, usually between the ages of 45 and 55. It can also affect people who have had their ovaries removed, people with premature ovarian insufficiency (ovaries that stop working early), and people whose menopause started early for medical reasons. A smaller number of men ask about bioidentical hormones for low energy or low sex drive, but there is little good evidence for this use.

Symptoms

Common symptoms

• Hot flushes and sudden waves of heat, sometimes with sweating and a racing heart
• Night sweats that soak bedding and disturb sleep
• Mood changes, irritability, anxiety or low mood
• Trouble sleeping or waking up tired
• Vaginal dryness, discomfort during sex, or repeated urinary infections
• Lower sex drive
• Brain fog — trouble concentrating or remembering words
• Joint aches and stiffness
• Irregular or changing periods during perimenopause

Symptoms in children

• This topic does not usually apply to children. Children do not go through the menopause and are not given hormone treatment for menopausal symptoms.
• A rare exception is a young person whose ovaries stop working early (premature ovarian insufficiency). They need specialist care, and any hormone treatment is arranged by a children's or adolescent specialist team.
• If you are worried about a young person's puberty or hormones, speak to their doctor rather than using any hormone product bought online.

Symptoms in older adults

• Symptoms such as hot flushes can last many years, and some people still have them in their 60s or later.
• The risks and benefits of hormone treatment change with age. Starting hormone therapy many years after the menopause, or at an older age, is usually considered more carefully.
• Older adults are more likely to take other medicines, so a full medication review with a doctor or pharmacist is worthwhile.
• Bone thinning (osteoporosis) becomes more likely after the menopause, so bone health is an important part of the conversation.

Causes

Main causes

• The natural drop in oestrogen and progesterone as the ovaries slow down and stop releasing eggs — this is the menopause itself
• Surgical menopause, when the ovaries are removed during an operation, which causes symptoms very suddenly
• Premature ovarian insufficiency, where the ovaries stop working before age 40 because of genetics, medical treatment or sometimes an unknown cause
• Some treatments such as chemotherapy or radiotherapy to the pelvis, which can affect hormone levels
• Marketing pressure — 'hormone imbalance' is a popular phrase online, but it is not a precise medical diagnosis, and many symptoms blamed on hormones have other causes such as stress, thyroid problems or low iron

Risk factors

• Smoking, which can bring on the menopause earlier and raises the risk of blood clots and heart disease
• A personal or family history of blood clots in a vein (such as deep vein thrombosis)
• A personal or family history of breast cancer or other hormone-sensitive cancer
• Being over 60, or many years past the menopause, when starting hormone treatment
• Uncontrolled high blood pressure, diabetes, or being very overweight
• Liver disease, or a history of migraine with aura
• Buying hormone products online or from unregulated sellers, where quality and ingredients are unknown

When to see a doctor

See a doctor urgently if:

• You have vaginal bleeding after your periods have stopped for a year or more
• You notice a new breast lump or change in the shape or skin of your breast
• You have a severe headache with changes to your vision
• You feel very low in mood, anxious, or have thoughts of harming yourself
• You think you are having a bad reaction to any hormone product, including a compounded one

Book a routine appointment if:

• Menopause symptoms are bothering you and you want to talk about options
• You are thinking about starting, changing or stopping bioidentical hormones, especially compounded ones
• You are buying hormone products online or from a clinic and want a second opinion
• Your symptoms are affecting sleep, work, relationships or mood
• You want to talk about bone health, heart health, or breast screening after the menopause

Diagnosis

There is no single test that tells you whether bioidentical hormones are right for you. Your doctor will mostly listen: your symptoms, when they started, how they affect your life, your periods if you still have them, and any medicines or hormone products you already use. They will ask about your health history, including blood clots, cancer, migraine and blood pressure. Your doctor can then explain the difference between licensed hormone treatments and compounded bioidentical products, and discuss what the evidence says. If you are using a compounded product, bring it (or a photo of the label) to the appointment so your doctor can see exactly what is in it.

Tests that may be done

• A full history and symptom review, including a review of any hormone products you take
• Blood pressure, weight and pulse measurements
• Blood tests may be used to confirm the menopause in some situations, for example if you are under 45, or to check thyroid, iron or vitamin levels that can mimic menopause symptoms
• Hormone blood or saliva tests are sometimes used to adjust compounded doses, but these are not reliable for this purpose — hormone levels naturally swing around, and a single result cannot guide a dose safely
• Breast screening and cervical screening status may be discussed
• A bone density scan is arranged only in specific situations, such as early menopause or a higher fracture risk

What to expect at your appointment

Expect a conversation rather than a quick prescription. Your doctor may want to see you more than once, and may suggest trying a licensed treatment first or a non-hormonal approach. They should explain the possible benefits and risks in plain terms and give you time to decide. If a compounded product has been suggested to you, it is fair to ask what evidence supports it, how its strength is checked, and how you will be monitored. Getting a second opinion is always acceptable.

Treatment

Treatment is about reducing symptoms and protecting long-term health, using the lowest effective support for as long as you need it. Options include lifestyle changes, non-hormonal treatments, vaginal treatments for dryness, and licensed hormone replacement therapy. Which one suits you depends on your symptoms, your age, your medical history and what matters to you. Most guidelines advise using licensed hormone products, because they have been tested for quality, dose accuracy and safety. Compounded bioidentical hormones are generally not recommended by major medical bodies, except in rare cases managed by a specialist such as an endocrinologist.

Self-care at home

• Keep a simple symptom diary for a few weeks so you can see patterns and share them at appointments
• Dress in layers, keep a cool drink nearby, and use a fan at night for hot flushes
• Cut back on alcohol, caffeine and spicy food if you notice they trigger flushes
• Aim for regular sleep and a consistent bedtime routine
• Stay physically active — even a daily walk helps mood and sleep
• Use a vaginal moisturiser or lubricant for dryness, available from a pharmacy without a prescription
• Stop smoking, and ask your GP or pharmacist for support if you want to quit
• Be cautious with supplements and 'natural hormone' creams sold online — check with your pharmacist first

Medical treatments

Medical options fall into a few broad groups. Licensed hormone replacement therapy replaces oestrogen, usually with a progestogen to protect the lining of the womb if you still have a womb; it comes as tablets, patches, gels or sprays, and there are also local vaginal versions for dryness. Non-hormonal prescription medicines can help with flushes and sleep when hormones are not suitable. Some people are offered talking therapy for mood and sleep difficulties. All of these are started at a low dose, reviewed regularly, and adjusted to suit you. Your doctor will also talk through the known risks, which vary depending on your age, how long you use treatment, and your personal health history. Compounded bioidentical products are not standard treatment and are not quality-checked in the same way, so discuss any product you are offered with a doctor or pharmacist before using it.

When is surgery considered?

Surgery is not a treatment for menopause symptoms. It may come up in two situations: if you have surgery to remove your ovaries, which brings on the menopause suddenly and may need hormone treatment afterwards; or if surgery is needed for another gynaecological reason. Your specialist team would discuss hormone support with you before and after any operation.

Living with this condition

Most people find a routine that keeps symptoms manageable: layers of clothing, a fan by the bed, a regular sleep and wake time, and gentle exercise. Plan around your energy — if mornings are harder, put important tasks later in the day. Keep a note of what you take and when, including any creams or gels, so reviews are straightforward. If you use a compounded product, ask for the exact ingredients and strength in writing and keep it with your medicines list.

Lifestyle tips

• Stay active most days, mixing walking, strength work and something you enjoy
• Keep alcohol within low levels and consider cutting down if flushes worsen
• Stop smoking — this is one of the single biggest things you can do for your heart, bones and clot risk
• Manage stress with breathing exercises, gentle yoga or time outdoors
• Keep hydrated and eat regularly to steady your energy
• Protect sleep with a cool, dark room and less screen time before bed
• Stay connected — coffee with a friend or a local group can lift a difficult week

Diet and exercise

A balanced diet with plenty of vegetables, fruit, whole grains, beans and lean protein supports energy and heart health. Calcium and vitamin D matter for bones — dairy, fortified plant milks, leafy greens and safe sun exposure all help, and your GP can advise on supplements if needed. Weight-bearing exercise such as walking, dancing or light weights helps keep bones strong, while strength and balance work reduces falls risk later on. Aim for movement you can keep up rather than a perfect plan, and build up gradually if you have not exercised for a while.

Mental health and emotional wellbeing

Mood changes, anxiety and broken sleep are common around the menopause, and they can feel unsettling. This is not a sign of weakness, and it is not 'just hormones' that you have to put up with. Talking therapies, peer support and, where appropriate, treatment for low mood can all help. If you ever have thoughts of harming yourself, please reach out for crisis support straight away and tell someone you trust — you deserve help quickly, and effective support is available.

Prevention

The menopause itself cannot be prevented — it is a natural part of ageing. What you can do is lower the chance of problems around it: not smoking, keeping active, eating well, keeping blood pressure and weight in a healthy range, and getting any new symptoms checked early. If you are thinking about hormone treatment, choosing licensed, monitored products rather than unregulated ones reduces the risk of unexpected side effects.

Vaccines

There is no vaccine for the menopause. Do keep up with routine vaccinations offered to you, such as flu and any others your local health service recommends, as these protect your general health.

Screening programmes

Keep up with the screening you are invited to — breast screening and cervical screening are offered at set ages in the UK and many other countries. Screening helps find problems early, when treatment works best. Ask your GP or local health service what you are due for, and mention any family history of breast, ovarian or bowel cancer so your risk can be assessed. Bone density checks are arranged only when there is a specific reason.

Complications

If left untreated

• Symptoms such as flushes, poor sleep and mood changes can continue for years and wear you down
• Sleep loss and low mood can affect work, relationships and day-to-day enjoyment
• Vaginal and urinary symptoms can become more uncomfortable and increase the chance of urine infections
• Bone thinning speeds up after the menopause, raising the risk of fractures later in life
• Heart health risk rises after the menopause, which is one reason lifestyle and blood pressure checks matter
• Unregulated compounded hormones may carry extra risks if the strength is wrong, ingredients are impure, or no one is monitoring you
• Hormone treatment is not suitable for everyone; using it without a proper review can be harmful for people with certain health conditions

Long-term outlook

The great majority of people get through the menopause and feel well again. Symptoms usually ease over time, and there are many safe ways to manage them in the meantime. The key is getting good information, choosing a monitored option that suits you, and having regular reviews rather than going it alone. Many people find this stage of life brings new energy and freedom once symptoms settle.
