Why Has My Cycle Changed After 40?
Have your periods become heavier, lighter, shorter, longer or less predictable than they used to be?
Perhaps you're spotting before your period, experiencing worsening PMS, waking through the night or wondering whether your hormones are changing.
If this sounds familiar, you're certainly not alone.
Many women notice significant changes in their menstrual cycle during their 40s, often years before menopause itself occurs.
In many cases, these changes are associated with the transition known as perimenopause.
What is perimenopause?
Perimenopause refers to the years leading up to menopause.
During this time, ovarian hormone production begins to change. These hormonal fluctuations can affect the menstrual cycle long before periods stop altogether.
While menopause is confirmed after twelve months without a menstrual period, perimenopause may begin years earlier.
For some women, symptoms begin in their late 30s. For others, changes may not become noticeable until their mid-to-late 40s.
How can periods change during perimenopause?
Every woman's experience is different.
Common changes may include:
Shorter cycles
Longer cycles
Heavier bleeding
Lighter bleeding
Irregular timing
Increased clotting
Spotting before periods
Changes in PMS symptoms
More painful periods
Missed periods
Some women notice only subtle changes, while others experience significant disruption.
It's not just your period
Menstrual changes are often accompanied by other symptoms, including:
Sleep disturbances
Anxiety
Mood changes
Hot flushes
Night sweats
Brain fog
Fatigue
Reduced stress tolerance
Changes in skin health
Changes in vaginal health
Many women are surprised to discover that some of these symptoms may be related to hormonal fluctuations occurring during perimenopause.
Looking at the bigger picture
At Diamond Creek Natural Medicine Centre, we rarely look at symptoms in isolation.
When a woman presents with changes to her cycle, we also consider:
Hormonal health
Sleep
Stress
Energy
Digestive health
Skin health
Reproductive history
Lifestyle factors
From a Chinese medicine perspective, women experiencing perimenopause may present with a variety of patterns, and no two experiences are exactly the same.
Some women may experience signs of Yin deficiency, while others may present with patterns involving Liver Qi stagnation, Blood deficiency, Kidney deficiency or a combination of several patterns.
Understanding these individual presentations helps guide a personalised treatment approach rather than assuming every woman requires the same support.
Is it definitely perimenopause?
Not necessarily.
While changes to your cycle may be associated with perimenopause, they can also occur alongside thyroid conditions, reproductive health concerns, stress, medical conditions or other hormonal changes.
If you're experiencing significant changes to your cycle, it's important to seek appropriate medical assessment and discuss any concerns with your healthcare provider.
When should you seek support?
If your cycle has changed and you're unsure why, it's worth seeking guidance.
Changes may be associated with perimenopause, but understanding what is happening can provide reassurance, clarity and a plan for moving forward.
You don't need to wait until symptoms become overwhelming before seeking support.
