What causes hormonal imbalance in women?
All of the occurrences listed above involve a predictable hormone imbalance. But sometimes, your body will throw in some less common fluctuations too which may require further attention from your doctor. These include:
Polycystic ovary syndrome
People with PCOS may have abnormally high levels of androgens (male sex hormones), which can cause symptoms such as irregular periods, unwanted hair on the body and face, and acne. The condition can also make it more difficult to conceive.11,12

Hysterectomy
While a hysterectomy can be done without removing the ovaries, if they are removed, this can lead to a sharp decline in oestrogen, progesterone, and testosterone levels, and even trigger an early menopause.13
Early menopause
When your periods stop before the age of 45, this is referred to as early
menopause.

Menopause before the age of 40 is called premature menopause. This is sometimes called premature ovarian failure, or primary ovarian insufficiency (POI). Premature menopause means that the ovaries aren’t working properly, so they stop producing eggs much earlier than usual.14
Sometimes this is a side effect of a treatment, like a hysterectomy. But it’s also possible for your ovaries to stop making normal levels of certain hormones naturally, causing periods to either stop or become
infrequent.
14 Premenstrual dysphoric disorder
Like PMS, premenstrual dysphoric disorder (PMDD) can occur a week or two before your period starts. Affecting approximately 5%–8% of women of reproductive age, the condition is also thought to be caused by increased sensitivity to hormonal fluctuations during the menstrual cycle (especially progesterone).15,16
However, PMDD causes more severe symptoms than PMS, including severe depression, irritability, and tension. As such, you should consult your doctor if you think you might be suffering with PMDD.15,16
