Nurse Advice & Daily Care

Introduction When your body starts behaving differently, it can feel unsettling. Maybe your periods have changed, your moods feel harder to steady, your sleep is broken, your skin is flaring, or you feel tired in a way that rest does not fix. Many of us wonder, quietly, “Is this hormones?” The causes of hormonal imbalance in women can include normal life stages, stress, thyroid problems, PCOS, perimenopause, medication effects, pregnancy-related changes, and other medical conditions. This guide explains what hormonal imbalance is, why it happens, the symptoms to watch for, what is common, and when it is safer to get checked. What Is Hormonal Imbalance? Hormonal imbalance means one or more hormones are higher, lower, or fluctuating in a way that affects how the body feels or functions. Hormones are chemical messengers. They help regulate periods, ovulation, fertility, mood, metabolism, sleep, temperature control, skin, hair growth, appetite, energy, and sexual well-being. Important hormones in women’s health include oestrogen, progesterone, testosterone, thyroid hormones, insulin, cortisol, prolactin, and reproductive hormones such as FSH and LH. A hormonal imbalance can affect women and people assigned female at birth at any age. It may happen during puberty, after stopping contraception, during pregnancy or after birth, during perimenopause and menopause, or because of conditions such as PCOS or thyroid disease. PCOS is described by the Office on Women’s Health as a condition involving hormonal imbalance and metabolism problems, affecting about 1 in 10 women of childbearing age. (Office on Women’s Health) PCOS Symptoms: What Irregular Periods May Be Telling You Why Does It Happen? The causes of hormonal imbalance in women are not always one single thing. Sometimes hormones shift during a normal transition. Other times, symptoms are a sign that something needs to be assessed. i. Life stage hormone changes Hormones naturally fluctuate across the menstrual cycle. Oestrogen and progesterone rise and fall each month, which can affect mood, energy, sleep, appetite, breast tenderness, discharge, and bleeding patterns. Perimenopause is another major hormone transition. Oestrogen can fluctuate unpredictably before periods stop, and this may cause hot flushes, night sweats, sleep disturbance, mood changes, brain fog, vaginal dryness, joint aches, heavier or irregular periods, and changes in libido. NICE guidance covers identifying and managing menopause, including premature ovarian insufficiency. (NICE) Pregnancy, miscarriage, abortion, breastfeeding, and the months after birth can also bring strong hormone shifts. These changes can affect bleeding, mood, hair shedding, sleep, skin, pelvic symptoms, and energy. ii. PCOS and ovulation problems PCOS is one of the common causes of hormonal imbalance in women, especially when symptoms include irregular periods, acne, increased facial or body hair, scalp hair thinning, weight changes, or difficulty getting pregnant. NHS guidance notes that women with PCOS may ovulate infrequently, leading to irregular or absent periods and fertility difficulties. (nhs.uk) iii. Thyroid problems The thyroid helps regulate metabolism, body temperature, heart rate, bowel habits, menstrual cycles, mood, and energy. An underactive thyroid may cause fatigue, weight gain, constipation, low mood, dry skin, hair thinning, heavy periods, and feeling cold. An overactive thyroid may cause anxiety, palpitations, weight loss, sweating, diarrhoea, tremor, lighter or irregular periods, and heat intolerance. iv. Stress, sleep, and blood sugar Stress does not “ruin” hormones overnight, but chronic stress, poor sleep, under-eating, over-exercising, alcohol, high caffeine intake, and unstable blood sugar can worsen symptoms. Cortisol, insulin, reproductive hormones, and thyroid function all interact. This is why the causes of hormonal imbalance in women often include both medical and lifestyle contributors. vi. Other possible medical causes Symptoms may also be linked to endometriosis, fibroids, adenomyosis, high prolactin, diabetes or insulin resistance, eating disorders, adrenal conditions, premature ovarian insufficiency, medication side effects, or gynaecological conditions affecting the womb or ovaries. Hormonal Acne: Causes and Treatment Options Signs and Symptoms Hormonal symptoms can be obvious, subtle, or easily mistaken for stress, burnout, ageing, or “just life.” Common symptoms include: Irregular periods Missed periods Heavy bleeding or flooding Bleeding between periods Painful periods Hot flushes or night sweats Mood swings, anxiety, irritability, or low mood Poor sleep or waking in the early hours Fatigue that feels out of proportion Brain fog or poor concentration Acne or oily skin Facial hair growth or scalp hair thinning Weight gain or difficulty losing weight Breast tenderness Low libido Vaginal dryness or pain with sex Headaches or migraines that follow a cycle Bloating, cravings, or appetite changes Palpitations or feeling shaky Feeling unusually cold or hot Constipation or diarrhoea Less obvious symptoms may include recurrent thrush-like irritation, urinary symptoms, joint aches, dry eyes, worsening PMS, emotional sensitivity, dizziness, and reduced exercise tolerance. What Is Normal and When to Pay Attention? Some hormonal changes are common, but “common” does not always mean “ignore it.” The key question is whether symptoms are new, worsening, disruptive, unusual for you, or linked with red flags. a. Common Changes These can be common but are still worth tracking: Mild PMS before a period Slight cycle variation from month to month Breast tenderness before bleeding Heavier or irregular periods during perimenopause Temporary cycle changes after illness, travel, stress, or stopping hormonal contraception Hair shedding after childbirth Mild hot flushes during perimenopause Mood changes that improve once bleeding starts b. Needs Urgent Attention Please seek urgent medical help or same-day advice if you have: Very heavy bleeding, soaking pads quickly, or passing large clots Bleeding after menopause Bleeding after sex Severe pelvic or abdominal pain Chest pain, shortness of breath, fainting, or sudden weakness Pregnancy with pain, bleeding, dizziness, or shoulder-tip pain New breast lump, nipple discharge, or skin changes Unexplained weight loss Symptoms of anaemia such as breathlessness, dizziness, racing heart, or extreme fatigue Severe mood changes, feeling unsafe, or thoughts of self-harm NHS guidance states that postmenopausal bleeding should be assessed and that people should be referred to a specialist clinic or hospital. (nhs.uk) ACOG also highlights that bleeding after menopause should be discussed with an obstetrician-gynaecologist.
