Hormone Imbalance: What It Really Means and Which Tests Matter

"Hormone imbalance" isn't a medical diagnosis. It's a catch-all phrase for symptoms such as tiredness, weight change, irregular periods, acne, low libido or low mood that may, or may not, have a hormonal cause. When hormones genuinely are the problem, it is usually a specific, testable condition: an underactive or overactive thyroid, PCOS (now being renamed PMOS), insulin resistance, low testosterone or perimenopause. The best next step is a proper assessment and the right blood tests through your doctor, not a social-media "hormone reset".

Hormones are chemical messengers that help control metabolism, sleep, mood, appetite, reproduction and more. They also naturally rise and fall across the day, the month and your lifetime. That's why vague "imbalance" talk can be so confusing. Here's how to separate real conditions from online myths.

What "hormone imbalance" means, and what it doesn't

Doctors don't diagnose "imbalance". They diagnose particular conditions, using symptoms, an examination and tests that compare your levels with reliable reference ranges. Many common symptoms, such as fatigue, bloating or stubborn weight, have causes that aren't hormonal at all: poor sleep, stress, low iron, depression, medicines, or simply a busy life. Labelling everything "hormones" can delay finding the real reason.

Real hormonal conditions worth knowing about

Condition	Common signs	Key test
Underactive thyroid	Tiredness, feeling cold, weight gain, constipation, low mood, dry skin, irregular periods	TSH and free T4
Overactive thyroid	Weight loss, racing heart, anxiety, heat intolerance, tremor	TSH and free T4/T3
PCOS / PMOS	Irregular periods, excess hair, acne, scalp hair thinning, trouble conceiving	Clinical assessment, testosterone, glucose tests, sometimes ultrasound or AMH
Insulin resistance / prediabetes	Often no symptoms; weight around the middle, dark velvety skin patches	HbA1c, fasting glucose or a glucose tolerance test
Low testosterone (men)	Low libido, erection problems, low energy, loss of muscle	Two early-morning fasting testosterone tests
Perimenopause	Changing periods, hot flushes, sleep and mood changes, brain fog	Usually diagnosed from symptoms over 45

Thyroid problems

An underactive thyroid is common and is most often caused by Hashimoto's disease, an autoimmune condition that mainly affects women between 30 and 50, according to the NHS. Symptoms build slowly and are easy to blame on stress. A simple blood test for TSH (thyroid-stimulating hormone) and T4 gives a clear answer, and treatment with daily thyroid hormone is well established.

PCOS, now PMOS

The WHO estimates that 10 to 13% of women of reproductive age have polycystic ovary syndrome, and up to 70% of them don't know it. It isn't just a fertility issue: it raises long-term risk of insulin resistance, type 2 diabetes and weight gain. In May 2026 an international consortium led by Monash University announced in The Lancet that PCOS is being renamed polyendocrine metabolic ovarian syndrome (PMOS), because the condition doesn't actually involve cysts and its metabolic side was being overlooked. The change will be phased in over about three years, so you'll see both names.

The international PCOS guideline recommends a 75g oral glucose tolerance test as the most accurate way to check blood sugar in people with the condition, whatever their weight. In South Africa, where type 2 diabetes is common, that's worth asking about.

Low testosterone

Testosterone naturally varies through the day, and one low result is not a diagnosis. A 2026 Endocrine Society statement reiterated that low testosterone should only be diagnosed with consistent symptoms plus at least two early-morning, fasting blood tests from an accredited lab. Weight gain, poor sleep, heavy drinking and some medicines can all lower testosterone, and those are worth addressing first.

Perimenopause

In perimenopause, oestrogen and progesterone swing unpredictably, sometimes for years. Mayo Clinic notes that hormone testing usually isn't helpful to confirm perimenopause for exactly that reason, though your doctor may check your thyroid.

Social-media myths and at-home tests

• "Adrenal fatigue." A 2018 editorial in the South African Medical Journal by Ross, Jones and Blockman concluded that current evidence does not support the existence of adrenal fatigue or the usefulness of supplements to "support" the adrenals, and noted that the US Endocrine Society does not recognise it as a medical condition. Real adrenal disorders do exist and are diagnosed with proper blood tests.
• "Cortisol belly" and "hormone-balancing" diets. Stress does affect cortisol, but no single food, drink or seed routine has been shown to "balance" hormones.
• At-home hormone panels. Finger-prick and saliva kits can be convenient, but a single sample taken at the wrong time of day or cycle can be misleading, and results aren't interpreted alongside an examination. The SAMJ authors note that in studies, salivary cortisol often didn't distinguish fatigued people from healthy controls.
• "Detoxing" hormones. Your liver and kidneys already clear hormones. There's no good evidence that cleanses or teas improve this.

Which blood tests to ask your doctor about

Which tests make sense depends on your symptoms, age and sex. Common, useful starting points include:

• TSH, with free T4 if abnormal, for tiredness, weight change, mood or cycle changes
• Full blood count and ferritin to check for anaemia or low iron, a very common cause of fatigue
• HbA1c or fasting glucose (or a glucose tolerance test if PCOS is suspected)
• Cholesterol profile, especially with PCOS, low testosterone or menopause
• For irregular periods: a pregnancy test, testosterone, prolactin and sometimes FSH/LH, timed as your doctor advises
• For men with symptoms: two early-morning fasting total testosterone tests

Lifestyle habits with real evidence

• Sleep. In a small JAMA study, ten young men who slept under five hours a night for a week had 10 to 15% lower testosterone. Consistent, sufficient sleep supports normal hormone rhythms.
• Movement, including strength training. The WHO stresses healthy eating and physical activity for everyone with PCOS, even if weight doesn't change, because they improve insulin sensitivity.
• Waistline and alcohol. Gradual weight loss where needed and drinking less help blood sugar, testosterone and menstrual regularity.
• Stress. Long-term stress affects sleep, appetite and cycles. Regular downtime matters.
• Weight-loss medicines. GLP-1 medicines such as Ozempic and Mounjaro are increasingly prescribed; they don't replace investigation of an underlying hormonal condition.

Be careful with "hormone" supplements

• Iodine, kelp and sea moss. Iodine is essential for the thyroid, but too much can also cause thyroid problems such as goitre and inflammation. The US upper limit for adults is 1,100mcg a day from all sources, and iodine can interfere with antithyroid medicines. If you have a thyroid condition, speak to your doctor before taking sea moss or kelp. See our sea moss guide.
• Ashwagandha. Studies have found small increases in thyroid hormone levels, and there are case reports of an overactive thyroid and of liver injury. It may interact with thyroid medicine, and it isn't advised in pregnancy. More in our ashwagandha guide.
• Inositol for PCOS. The international guideline notes it offers limited clinical benefit and that metformin is more effective for metabolic features.
• Anything promising to "balance hormones". Be sceptical. Herbal products can contain hidden ingredients and can interact with contraception and other medicines.

See a doctor if…

• Your periods have stopped for three months or more (and you're not pregnant), or are very irregular.
• You have unexplained weight loss, a racing heart, tremor or a swelling in your neck.
• You notice new excess facial or body hair, a deepening voice or rapid hair loss.
• You have extreme thirst, frequent urination or blurred vision. Seek urgent care if you also feel very unwell.
• You have low libido or erection problems lasting months.
• Tiredness or low mood persists for weeks. SADAG's helpline is 0800 567 567; in an emergency call 112 or 10177.

Frequently asked questions

What are the signs of a hormone imbalance in women?

Irregular or absent periods, acne, excess hair, unexplained weight change, persistent tiredness and mood changes can all have hormonal causes, such as thyroid disease or PCOS. Blood tests help find the reason.

Can a blood test show hormone imbalance?

Blood tests can diagnose specific conditions, such as thyroid disease or low testosterone. Timing matters, and results need to be read alongside your symptoms.

Is adrenal fatigue real?

No. There's no evidence it is a real medical condition. Genuine adrenal disorders exist but are rare and diagnosed with specific tests.

Why has PCOS been renamed PMOS?

Because the condition doesn't involve true cysts and has important metabolic effects. The new name, polyendocrine metabolic ovarian syndrome, was announced in 2026.

Can sea moss affect my thyroid?

Yes. Sea moss contains iodine, and too much iodine can upset thyroid function. Check with your doctor if you have a thyroid condition.
