Perimenopause, menopause and HRT • Costa del Sol

You want to feel
like yourself again.
That's a medical question.

Not a phase to be endured. Not stress. Not your age. The fog, the broken nights, the body that changed without permission, the drive that vanished, the mood that isn't yours. These are measurable, and you're allowed to want your life back.

Reachable this week No referral English or Dutch

What perimenopause and menopause actually are, how they are diagnosed, and what the evidence says about hormone therapy. Written and answered by an endocrinologist, in Endocrinology and Internal Medicine, on the Costa del Sol.

Every article here is free. Having it read against your case is the paid part.

  • The fog. Words gone mid sentence. You have started to worry about it.
  • The nights. Three in the morning, soaked, then awake until six.
  • The body. Weight around the middle, hair in the brush, a shape you didn't choose.
  • The intimacy. Dryness, pain, no drive, and infections that keep coming back.
  • The mood. Flat, tearful, short tempered. You don't recognize her.

You could wait
for this chair.

A referral, a waiting list, and a short appointment with someone who has never seen your file. Or you speak to the specialist this week, in English or Dutch, and walk into that appointment already knowing what to ask for.

Why This Is Hard To Find

A hormone doctor, for a hormone problem.

Menopause is a hormonal event, and it does not stay in one place. It reaches bone, heart, metabolism, sleep and mood at the same time. Reading all of that together is what two specialties are for.

EndocrinologyThe hormone specialty. Not a general practice that added menopause last year, and not a confident voice online with no medical training at all.
Internal MedicineThe discipline of the whole body, and the basis of serious medical thinking. It is why your heart, your bones and your medication belong in the same conversation.

Fourteen years of medical training, board certified in Spain, three health systems behind him, and a career spent in hormonal and metabolic medicine. And he answers you himself.

You are not imagining it

You were told it was just your age.

Nothing was measured. It was a short appointment, and you left with everything you came in with.

Free to read. Nothing to enter.

Every one of these is a hormone question

Most women have raised these one at a time, with different people, and had each one answered on its own. Together they are one story.

01

Brain fog

Losing the word, losing the thread, rereading the same paragraph. It is the one women worry about most, and the one they are least likely to say out loud. It is also very common, and it is worth raising.

Cognition
02

Sleep that broke

Waking at three, soaked, then lying there. Everything else on this list gets worse when the sleep goes, which is why it's rarely just the sleep.

Nights
03

Dryness, pain, and infections that return

Around half of women have this, and very few mention it. Unlike the hot flashes it does not settle on its own, so it is worth raising early rather than late. Recurrent urinary infections belong to the same cause.

Intimacy
04

The drive that disappeared

Not a relationship problem, and nothing to do with willpower. There is a hormone behind it that women are rarely told they still make.

Libido
05

A mood that is not yours

Flat, tearful, irritable, anxious in a way you never were. An antidepressant can be exactly right. It is worth having the hormones looked at in the same conversation, so the choice is made on the whole picture.

Mood
06

The middle, and the hair

The shape changes while the scale barely moves, and there is more hair in the brush. Both follow the same shift, and neither is really a question of eating less.

Body

Six things women describe here

Mark the ones that are true of you. Fifteen seconds, nothing entered, nothing sent.

The panel could not answer the question.

In these years the levels move week to week, so a single panel often reads normal while everything you described is still true. What you notice is the evidence, and it is worth bringing.

Ask what is worth checking
Four steps

From the symptom
to the specialist

In order, or straight to the part you came for.

Start here

Six complaints, or one story

You have probably raised these one at a time, to different people, and had each one answered separately.

The fog went to one doctor. The sleep to another. The dryness to nobody. Put together, in front of someone who works in hormones, they are one story. And they belong to the years before anything stops, which is where most of the disruption lives and where almost nobody is looking.

Put them together for a specialist
Why nobody found anything

The panel was never built to answer your question

You were tested, told the numbers were normal, and sent home with everything you walked in with.

The British national guideline is unusually blunt about this. In women aged 45 and over, perimenopause and menopause are diagnosed from symptoms and menstrual history, without routine hormone testing, because the levels fluctuate too much to be interpreted. Which means the test was never going to settle it, and what you described in the room was the evidence all along. Knowing that changes the next appointment you have.

Have your case read properly
What is moving while you wait

Nothing hurts, and that is the problem

Being told to give it time is not neutral. Three things move during exactly those years, and none of them announces itself.

Bone loss runs fastest from about a year before the final period through to two years after it, which is precisely the window in which almost nobody is scanned. Muscle falls and deep abdominal fat rises while the scale barely moves. And the dryness and urinary symptoms advance rather than settle. None of it is a certainty about you, and all of it is easier to act on early than late.

Ask what is worth measuring now
And this is what decides it

You were shown one decision. It is several.

What arrives as a single yes or no actually contains a decision about route, a decision about timing, and a decision about what else you carry.

Route is not interchangeable: a 2023 systematic review screened 1,369 papers and included 51 that compared the two routes directly in postmenopausal women. Timing changes the whole picture. And where estrogen is not an option there is now a class that is not a hormone at all, carrying one specific interaction trap that has to be known about. Reading all of that against your heart, your bones and your medication is what two specialties are for.

Ask the hormone specialist
Twelve articles, every number traced to published research. Read the journal
What is worth knowing now

How long this usually goes on for.

Seven and a half years. Among 1,449 women with hot flashes and night sweats in the Study of Women's Health Across the Nation, the median total duration was 7.4 years.
And 4.5 years after the last period. In the same study, that is the median time they persisted once periods had stopped.
Longer if they started early. For women whose symptoms began while they were still having periods, the median course ran beyond 11.8 years. Median means half of them had it longer.
The one that does not fade. Dryness, pain and returning urinary infections. The 2025 European Society of Endocrinology guideline puts prevalence at 50 to 75 percent after breast cancer treatment. Unlike the hot flashes, this one advances rather than settles.
Bone, quietly. Loss runs fastest around the final period, and it does not announce itself, which is exactly why it is worth measuring while it matters.
The shape, not the scale. Muscle falls and deep abdominal fat rises through the transition, which is why the weighing scale is the wrong instrument for it.

These are findings in populations, not predictions about you, and none of them is a diagnosis. The duration figures are from the Study of Women's Health Across the Nation, the prevalence figure from the 2025 European Society of Endocrinology guideline. Every figure above is traced to its source in the journal.

Some of this is easier
to act on early.

Bone density, muscle and the tissue changes all move through these years. None of it is a certainty about you, and all of it is easier to act on while it is still early.

How He Thinks

Two appointments. The same woman.
Opposite answers.

If you have been told two different things, you are not imagining it. Both answers can be given in good faith, and they still leave the question open.

One appointment Handed something within the week Symptoms described, a decision made quickly, and nobody established what else was going on or what else you carry.
The other appointment Tested, normal, sent home The same symptoms, one result inside a printed range, and a suggestion to give it time.

Both of those are quick answers.
Neither one is an assessment.

The guideline position is that at 45 and over this is settled on symptoms and menstrual history, not on a hormone level. So the appointment that tested you was measuring against something that cannot settle it, and the appointment that moved quickly did not get to the rest of the questions.
A quick answer asks whether you clear a threshold. An assessment asks what is actually happening to you. Your bones, your heart, your metabolism and your medication belong in that answer. That is what having Endocrinology and Internal Medicine in the same room is actually for, and it is why the honest answer is sometimes that your hormones are not the problem.

The 45-and-over rule is the British national guideline position, in the wording this site uses throughout. The prevalence of the intimate symptoms is from the 2025 European Society of Endocrinology guideline. Both are set out in the article on how it is diagnosed.

Being told you are fine is not the same as being assessed.
Most of the time, nobody has put it together yet.

What is on offer is knowledge, guidance and consultation, and nothing else.

Not "managing symptoms". Getting her back.

Every woman who writes describes the same three things, and none of them is a lab value.

01

Quality of life, back

Sleeping through. Thinking clearly. Wanting things again. The ordinary days stop being something to get through.

The whole point

Yourself, back

Not a calmer version. Not a coping version. The woman your family recognizes, in her own temper and her own energy.

Not a compromise

A note from the doctor

Most women get to the end of a consultation having talked about sleep and tiredness, and never mention the rest. Dryness. Sex that hurts. A drive that has simply gone. A mood you don't recognize as your own.

You can write those words to me plainly. I've heard all of them before and none of them is too small to raise.

I write and review every page here myself, and I answer the messages myself too. I won't tell you what to take. I'm also not going to pretend one number settles anything, because it doesn't. What I will do is read your situation properly and tell you what I actually think, including the times when the honest answer is that your hormones are fine and the problem is somewhere else. Plenty of women hear that from me. It's still worth knowing.

Write it rather than say it
