A plain-language starting point. What is happening, what it can look like, how to look after yourself while you support her, and where to find reliable medical information.
Perimenopause most often begins between 45 and 55, but symptoms can start earlier. The average age of menopause itself in the UK is 51.
Medically, menopause is the point at which she has gone twelve months without a period. Everything before that is perimenopause; everything after is postmenopause.
For many women, symptoms last between four and eight years. For some, they continue longer. This is a marathon, not a week of hot flushes.
There are more than 30 recognised symptoms, affecting sleep, mood, memory, joints, skin, heart and sexual health.
Hormone replacement therapy (HRT) is the most effective treatment for many symptoms. Non-hormonal options exist too. Her GP or a menopause specialist can talk her through the risks and benefits.
What can look like irritability, distance or disinterest is often her body responding to significant hormonal change. She may not fully understand it either.
Every woman's experience is different. She may have a few of these, or many, and they can change over time. Want the partner's-eye explanation? Read What is menopause and Symptoms explained.
Read the basics so she doesn't have to explain everything. Understanding the biology stops you taking symptoms personally.
Night sweats and broken sleep can affect you both. It's okay to keep your own anchor points: exercise, friends, quiet time.
"What would help right now?" beats guessing. Sometimes she wants solutions; often she just wants to be heard.
If a conversation is escalating, it's fine to say you love her and you'll pick it up later. Stepping back is not abandoning her.
Walks, a cup of tea, touch that isn't about sex. Small, low-pressure moments of closeness matter more when big ones feel hard.
Secondary stress is real. Talk to a friend, use the community forums here, or speak to your own GP if it's affecting your mental health.
