Perimenopause: Symptoms, Weight Changes, and When to Get Help
Perimenopause can be confusing because it does not always announce itself clearly. One month your period is early. Another month it is late. Sleep changes. Mood changes. Weight gathers around the middle. You wonder if it is stress, ageing, hormones, or all of the above.
Often, it is all of the above.
What is perimenopause?
Perimenopause is the transition phase before menopause. Menopause is confirmed after 12 months without a period. Perimenopause can begin years before that, commonly in the 40s, though timing varies.
During this phase, estrogen and progesterone can fluctuate. Symptoms may be steady for some women and unpredictable for others.
Common symptoms
You may notice:
- Irregular periods
- Heavier or lighter bleeding
- Hot flashes
- Night sweats
- Sleep disruption
- Mood changes
- Brain fog
- Vaginal dryness
- Lower libido
- Belly weight gain
- Joint aches
Not every symptom is "just hormones." Heavy bleeding, bleeding after sex, severe pain, or very sudden changes should be checked.
Why weight changes happen
Perimenopause can change where fat is stored, but weight gain is usually multi-factorial. Muscle mass tends to decline with age, sleep gets disturbed, stress may rise, and insulin resistance can become more visible.
This is why eating less and doing more cardio may not be enough. Strength, protein, sleep, and metabolic screening matter.
What can help
Support may include:
- Strength training
- Protein and fibre-focused meals
- Blood sugar and thyroid testing when needed
- Sleep support
- Menopause symptom treatment
- Mental health support
- Medical weight care for eligible women
Perimenopause is a good time to build a preventive health plan, not wait until symptoms become unbearable.
RERO's view
Women are often told to tolerate perimenopause quietly. RERO takes a different view: this is a valid health stage, and weight changes during it deserve proper assessment.
