What is menopause, and how long does it last?

What changes in your body at menopause?

The final period is only the marker. Around it, a lot of the body's day-to-day management shifts. Estrogen (oestrogen in the UK) looked after temperature control, bone, the heart and blood vessels, muscle, the vagina and bladder, sleep and mood, so when it changes, those areas change with it. Let's be clear about what that list is. It isn't a verdict on your health or your future. It's a map, and every item on it has something that helps, which is the whole point of knowing where the terrain runs rough.

Hot flashes (hot flushes in the UK) and night sweats get the most attention, and fairly so. SWAN, the long-running US study of women through midlife, found they are usually at their worst in the year or two around the final period. How bothersome they are differs from woman to woman. Some find them an occasional nuisance, others find them soaking the sheets and derailing the workday. Bothersome flashes are a recognized reason to ask about treatment, and many women find it worthwhile to raise them with an OB-GYN (a GP in the UK) rather than sit through them politely.

Bone is the one with a deadline. The fastest bone loss of adult life happens in the years just before and after the final period, according to SWAN's bone research. That makes these years a good moment to put bone health into the conversation, while there is the most to protect. It is a quiet process, and quiet processes are easy to leave off the agenda. Putting it on the agenda early is the sensible move, and it costs little.

The heart changes too. LDL cholesterol jumps around the final period, and heart disease risk rises steadily from here, according to SWAN's cholesterol research. Heart health belongs in any honest account of menopause, right next to the hot flashes. Many women find these years a natural point to ask their primary care doctor (GP in the UK) about knowing their numbers and what they mean for the decades ahead.

Muscle mass and power keep declining without training, a process researchers call anabolic resistance. That is not a reason to do less. It is the reason the evidence favors heavier, more deliberate training, and it is why the old advice to potter gently through midlife deserves retiring. Muscle is not decoration. It is how you carry shopping, climb stairs, recover from a fall and stay independent, so a slow decline is worth taking seriously, and worth meeting with something that works.

Fat continues to shift toward the abdomen, even without weight gain. That is a redistribution, not a character flaw, and the scale can miss it entirely. Health here is about strength, function and how you feel, not a number on a dial. If your waistband tells a different story from your weight, that is the change, not a failure on your part, and it responds to the same tools that serve muscle and bone.

Vaginal and urinary changes are among the least discussed and the most worth discussing. Dryness, painful sex, urgency and repeated UTIs are common, and they can get worse over time without treatment. That is the opposite of a symptom that fades by itself, and it is a good reason not to treat embarrassment as a plan. Many women find it a relief to bring the subject up, because the options are simple and well established.

Then there is sleep and mood. Night sweats and early waking disrupt sleep for many women, and low mood, anxiety and brain fog are common. None of it means you are losing your grip. It means your body is in a well-documented transition, and brain fog usually improves after menopause. Each piece of this picture can be addressed, and several of them can be addressed together.

Joint aches and drier, thinner skin are common in these years as well. They rarely make headlines, but they shape daily life, from how easily you get out of a chair to how you feel about the mirror. They are part of the same transition, and the answer is not to stop moving or to buy your way out of ageing. Staying active and keeping up a basic skincare routine are the plain answers, and they sit comfortably alongside everything else on this map.

What helps with menopause symptoms and long-term health?

The evidence points to a short list: heavy lifting, enough protein, hormone therapy where it suits, and targeted treatment for sleep, mood and vaginal symptoms. None of it needs an anti-aging routine or a shelf of products. The basics are unglamorous, and they are where the research is.

For muscle, the answer is heavy, progressive lifting: loads that feel challenging and that rise over time. For bone, the evidence supports heavy and impact loading together with enough calcium and vitamin D. "Take it easy at your age" is advice worth retiring. Starting points differ, so many women begin lighter than they expect and add load gradually, building confidence along with strength. Strength training also helps with the abdominal fat shift, alongside high-intensity interval training (HIIT), adequate protein, decent sleep and less alcohol.

Protein does the other half of the job. A sensible daily target sits in the key numbers on this page, and it comes with a pattern: protein at several meals through the day rather than most of it at dinner. That approach comes from the PROT-AGE position paper and the ISSN position stands, and the spread is part of the target, not a detail. Many women find that the easiest way in is to look at breakfast first, because that is where protein tends to run short.

HRT, usually called hormone therapy in the US, deserves a fair hearing. The Menopause Society's 2022 position statement describes the balance as favorable for bothersome hot flashes and for preventing bone loss in women under 60 or within 10 years of menopause onset who have no contraindications. In the UK, NICE guideline NG23 (updated 2024) covers the same ground. Most is not all. Your own medical history decides which side of that line you are on, and that is a conversation worth having with the facts in hand, not the old headlines.

For vaginal and urinary symptoms, the options are vaginal estrogen, moisturizers (moisturisers in the UK) and pelvic floor training. Because these changes can worsen without treatment, many women find that raising them sooner rather than later gives them more choice. An OB-GYN or GP can talk through which fits, and none of these options asks you to put up with the problem.

For sleep, three things have support: treating the flashes that wake you, CBT-I (cognitive behavioral therapy for insomnia) and a cool bedroom. For mood and brain fog, the list is exercise, better sleep, HRT or other treatment, and CBT. Treating night sweats helps sleep, better sleep helps mood, and exercise helps both. Starting with whichever symptom bothers you most often brings improvements elsewhere.

The same few tools keep turning up across this page, and that is good news. Lifting serves muscle and bone. Exercise serves mood, and also joints, since aching joints are a reason to keep moving with a plan that suits you, not a reason to stop. Staying active and a simple skincare routine cover the rest of the joint and skin picture, and none of it requires the anti-aging aisle. One good decision tends to pay out in several places, which is the best argument for starting with the one that feels most doable.

Next steps

If you take three things from this page, let them be these. First, many women find it helps to jot down which changes bother them most before an appointment with an OB-GYN or primary care doctor (a GP in the UK). Second, consider adding a strength session and a little more protein to your week, then building from there. Third, if symptoms are getting in the way, it is reasonable to ask where hormone therapy fits for you and your history. The signs in the red flags list are good reasons to book a prompt appointment. The pages linked from this hub go deeper on symptoms, treatment, nutrition, supplements, training, sleep and health checks, so follow the one that matches your biggest question. Strong, independent decades are built from choices like these. Still, menopause is not one size fits all, and what fits you is yours to decide.
