Fibroids are most commonly found in women during their reproductive years, often beginning in their 30s. It is estimated that 70 to 80 per cent of women develop one or more fibroids at some stage during their reproductive life.
The exact reasons and mechanisms behind the development of fibroids in the uterus remain unclear. However, it is known that fibroids grow under the influence of oestrogen and progesterone. Scientific studies confirm that elevated oestrogen levels, in particular, contribute to the growth of a myoma.
During menopause, hormonal balance fluctuates, which can affect the growth of fibroids. This is especially evident during perimenopause, when progesterone levels decline more rapidly than oestrogen levels, resulting in oestrogen dominance: an excess of oestrogen relative to progesterone.
In most cases, fibroids do not cause symptoms and are often discovered "by chance" during a routine medical examination.
If the fibroid is larger, it is more likely to cause symptoms. Possible symptoms include:
- Heavy bleeding or pain during menstruation
- Intermenstrual bleeding
- Pain during intercourse
- Frequent urination (due to pressure on the bladder)
- Pelvic pain or lower back pain
- Digestive issues and sharp abdominal pain
- Reduced fertility
