Premature Ovarian Insufficiency (also referred to as Premature Ovarian Failure) can be a confusing and emotionally challenging diagnosis, particularly as it often occurs much earlier than many women expect.
Understanding what POI is, how it differs from menopause, and recognising the symptoms can help you seek the right support and treatment sooner.
Menopause is defined as having no period for 12 consecutive months with no other medical explanation. This is when the ovaries stop releasing eggs and oestrogen levels decline, often leading to symptoms such as hot flushes, mood changes and sleep disturbances. But when menopause occurs before the age of 45, it is considered an early menopause, and when it happens before 40, it is classed as premature.
Premature ovarian insufficiency occurs when ovarian function declines earlier than expected. For many women, the first and most noticeable sign is the loss of regular periods. However, there is also a range of other physical and psychological changes that could appear.
Below, we explore the most common premature ovarian insufficiency symptoms and how they might be affecting your health.
Symptoms of Premature Ovarian Insufficiency
Hot flushes
Hot flushes are one of the hallmark symptoms associated with falling oestrogen levels. They often come on suddenly and may be accompanied by sweating, dizziness, and a racing heart. These episodes can be disruptive during the day and particularly uncomfortable at night.
Insomnia
Sleep disturbances are common with POI. Difficulty falling asleep, waking frequently during the night, or early morning waking can all be linked to hormonal fluctuations, particularly low oestrogen and progesterone levels.
Low libido
Many women with POI notice a significant reduction in sexual desire. Androgen hormones, including testosterone, often fall to levels lower than those seen in natural menopause. This sudden hormonal shift can end up having a profound impact on libido, arousal and overall sexual wellbeing.
Loss of concentration
Brain fog, difficulty focusing, and reduced mental clarity are frequently reported. Estrogen plays a key role in cognitive function, and its decline can affect attention and productivity.
Joint pain
Falling oestrogen levels reduce the hormone’s natural anti-inflammatory and lubricating effects within the joints. As a result, joint stiffness, aches and pains are common premature ovarian insufficiency symptoms that can affect daily movement and comfort.
Changes to the hair and skin
Oestrogen supports collagen production and healthy hair growth. When levels drop, skin may become thinner, drier or less elastic, while hair can appear drier, weaker or begin to thin.
Depression and anxiety
Mood changes can be particularly severe with POI due to significant and sudden hormone fluctuations. Beyond the physical effects, the diagnosis itself can impact emotional wellbeing, leading to low mood, anxiety, reduced self-esteem and feelings of inadequacy, especially around concerns about future fertility.
Low thyroid
The thyroid is a gland that makes hormones that control your body’s metabolism and energy level. Low levels of thyroid hormones can affect your metabolism and can cause very low energy, mental sluggishness, and other symptoms.
Brittle bones
The hormone oestrogen helps keep bones strong. Without enough oestrogen, women with POI often develop osteoporosis. This is a bone disease that causes weak, brittle bones that are more likely to break.
Memory loss
Short-term memory issues and difficulty retaining information are commonly reported. These cognitive changes are closely linked to declining oestrogen levels and can be distressing if not properly addressed.
Vaginal dryness
Reduced oestrogen can lead to thinning and drying of vaginal tissues, often resulting in discomfort or pain during intercourse. This symptom can significantly affect the quality of life and intimate relationships.
Recurrent thrush and urinary symptoms
POI can cause the skin around the vulva to become thin, sensitive and itchy, increasing susceptibility to thrush. The bladder wall may also become thinner and less elastic, contributing to recurrent cystitis and stress incontinence.
“POI is not just a reproductive condition; it affects every aspect of a woman’s physical, emotional, and long-term health. Too many women experience years of symptoms without clear answers or adequate support. Greater awareness, earlier diagnosis, and access to specialist-led, individualised care are essential to ensure that women with POI can manage their symptoms effectively and protect their future wellbeing.” – Dr Ghazala Aziz-Scott
Recognising premature ovarian insufficiency symptoms early is crucial, as untreated POI can have long-term implications for bone, heart and mental health.
