During menopause, hormonal changes occur in the female body, including a reduction in the sex hormone oestrogen. These hormonal fluctuations can cause menopausal symptoms such as hot flushes, sleep disturbances, and mood swings.
Oestrogen is essential for maintaining vaginal health. It keeps the vagina moist and clean, supports the vaginal flora (a balance of healthy and potentially harmful bacteria), and inhibits the growth of unwanted bacteria and fungi.
In perimenopause, progesterone levels decrease more rapidly than oestrogen levels, which can lead to oestrogen dominance. This may result in increased discharge.
As oestrogen levels decline further during menopause, the healthy vaginal flora can become disrupted. Low oestrogen levels often lead to a thinner, drier vaginal wall and a reduction in healthy bacteria and fungi. This imbalance in the vaginal microbiome, combined with dryness, can cause irritation and changes in the colour, smell, consistency, and amount of discharge.
The changes are somewhat similar to those experienced during your menstrual cycle. Immediately after your period (when the uterine lining is being rebuilt), discharge may be less and clearer. Around ovulation (when oestrogen levels rise), discharge increases and becomes mucus-like, thin, and slippery, resembling egg whites. After ovulation, the texture changes to a creamy, sticky consistency and turns white or light yellow.
Research indicates that two-thirds of women in menopause experience vaginal issues. Vaginal dryness is the most common complaint, though some women experience the opposite: increased and mucus-like discharge. A quarter of women report excessive or abnormal discharge. After menopause, when hormone levels stabilise at a new low, these symptoms often subside.
