What is perimenopause?
Perimenopause is the time leading up to menopause when the ovaries gradually begin to change how they function. During this stage, hormone levels can rise and fall unpredictably rather than following a regular pattern.
These hormonal changes can affect the menstrual cycle and cause a wide range of symptoms. Some women notice only mild changes, while others experience more significant symptoms that affect daily life.
Common symptoms of perimenopause
Symptoms can vary widely, but may include:
-
sleep problems
-
mood changes or anxiety
-
headaches
-
joint aches
-
changes in skin or hair
Symptoms can come and go and may not follow a clear pattern, especially in the earlier stages.
