Hormonal Imbalance in Women: Symptoms, Causes, and When to Get Help

A hormonal imbalance occurs when you have too much or too little of one or more hormones in your body. Hormones are chemical messengers produced by glands in the endocrine system, including the ovaries, thyroid, adrenal glands, and pituitary gland. Even small changes in hormone levels can have significant effects on your health and wellbeing.

Some degree of hormonal fluctuation is normal, levels naturally change throughout your menstrual cycle, during pregnancy, and as you approach menopause. However, persistent imbalances can cause symptoms that interfere with your quality of life.

Symptoms vary depending on which hormones are affected, but common signs include:

• Irregular periods, cycles that are too long, too short, or unpredictable
• Heavy or very light periods
• Missed periods (when not pregnant)
• Acne, particularly along the jawline
• Excess facial or body hair (hirsutism)
• Hair thinning or loss
• Unexplained weight gain or difficulty losing weight
• Fatigue and low energy
• Mood changes, anxiety, or depression
• Sleep disturbances
• Low libido
• Hot flushes or night sweats
• Vaginal dryness
• Difficulty conceiving

Many factors can disrupt hormonal balance:

• Polycystic ovary syndrome (PCOS), one of the most common causes, affecting ovulation and androgen levels
• Thyroid disorders, both overactive (hyperthyroidism) and underactive (hypothyroidism) thyroid can cause symptoms
• Perimenopause and menopause, natural decline in oestrogen and progesterone
• Primary ovarian insufficiency, when ovaries stop functioning normally before age 40
• Stress, chronic stress elevates cortisol, which can affect other hormones
• Weight changes, both underweight and overweight can disrupt hormone production
• Certain medications, some drugs can affect hormone levels
• Pituitary disorders, the pituitary gland controls many hormonal functions
• Diabetes and insulin resistance, closely linked to hormonal regulation

Diagnosis typically involves:

• Medical history, your doctor will ask about your symptoms, menstrual cycle, and general health
• Physical examination, checking for signs like acne, excess hair growth, or weight changes
• Blood tests, to measure levels of various hormones including oestrogen, progesterone, testosterone, thyroid hormones, FSH, LH, and prolactin
• Pelvic ultrasound, to examine the ovaries and uterus

Testing is usually timed to specific days of your menstrual cycle, as hormone levels naturally fluctuate.

Yes. Hormones control ovulation, and imbalances can prevent the release of eggs or affect the uterine lining's ability to support pregnancy. Conditions like PCOS, thyroid disorders, and hyperprolactinaemia are common hormonal causes of fertility difficulties.

The good news is that many hormone-related fertility issues are treatable. Once the underlying imbalance is identified, targeted treatment can often restore ovulation and improve the chances of conception.

Treatment depends on the underlying cause and may include:

• Lifestyle modifications, diet, exercise, and stress management can significantly improve hormonal balance
• Hormonal contraceptives, can help regulate periods and reduce symptoms of excess androgens
• Thyroid medication, to correct underactive or overactive thyroid
• Metformin, often used in PCOS to improve insulin sensitivity
• Hormone replacement therapy, for menopausal symptoms
• Fertility medications, to induce ovulation if trying to conceive
• Anti-androgen medications, to reduce symptoms like acne and excess hair

Treatment is individualised based on your specific situation, symptoms, and whether you're planning pregnancy.

Yes, lifestyle modifications can make a meaningful difference:

• Maintain a healthy weight, even modest weight loss can improve hormone levels in women with PCOS
• Regular exercise, helps regulate insulin and reduces stress hormones
• Balanced diet, focus on whole foods, adequate protein, and limiting processed sugars
• Manage stress, chronic stress affects cortisol and can disrupt other hormones
• Prioritise sleep, poor sleep affects hormone production
• Limit alcohol, excessive alcohol can affect oestrogen metabolism

Consider seeking help if you experience:

• Persistent irregular or absent periods
• Symptoms that affect your quality of life
• Difficulty conceiving after 12 months (or 6 months if over 35)
• New or worsening symptoms like excess hair growth or hair loss
• Unexplained weight changes despite healthy habits
• Severe mood changes or depression

Early assessment allows for appropriate testing and treatment before symptoms worsen or affect fertility.
