High Testosterone — UK Health Guide
High testosterone (also called hyperandrogenism) is when testosterone levels in the blood are higher than the normal range. In the UK, testosterone is typically measured in nanomoles per litre (nmol/L), and what counts as "high" differs between men and women. For men, normal testosterone is usually 7.7–29.4 nmol/L; for women, normal levels are much lower at 0.3–2.4 nmol/L. High testosterone can cause various physical and health effects, and it's important to understand what your levels mean and when to seek NHS guidance.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
High Testosterone — Symptoms and Health Effects
In men, elevated testosterone is relatively uncommon but can cause symptoms including increased aggression, mood swings, acne, male pattern baldness, and infertility. It may also lead to liver problems and increased risk of heart disease if very high. In women, high testosterone is more commonly encountered and often related to polycystic ovary syndrome (PCOS). Symptoms in women include irregular periods, excess facial and body hair (hirsutism), male pattern baldness, acne, deepening voice, and difficulty conceiving.
High testosterone can also affect weight management and metabolism. Some individuals with elevated testosterone experience increased muscle mass, which is why testosterone levels are sometimes relevant to weight, body composition discussions, and using our free BMI calculator to check your overall health context.
If you suspect your testosterone is elevated, your GP can arrange a simple blood test to measure your levels accurately. NHS guidance recommends testing if symptoms are present or if you have underlying health concerns.

NHS Guidance and When to See Your GP
In the UK, if you experience symptoms of high testosterone such as irregular periods, excessive hair growth, acne, infertility, or mood changes, your GP should be your first point of contact. They can order a testosterone blood test and, if needed, refer you to an endocrinologist (hormone specialist) through NHS services.
Treatment depends on the underlying cause. For women with PCOS, lifestyle changes including sustainable weight management, regular physical activity, and dietary adjustments are often recommended first. Our free weight converter and progress tracker can help you monitor your health journey alongside any medical treatment your GP recommends. Men with high testosterone may need medication or specialist input depending on the cause.
The NHS emphasises that high testosterone should be investigated to rule out serious conditions like tumours or other endocrine disorders.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What are normal testosterone levels in the UK?
In men, normal testosterone is approximately 7.7–29.4 nmol/L. In women, normal levels are much lower at around 0.3–2.4 nmol/L. Your GP can arrange a blood test to measure your exact levels. The NHS uses these ranges to determine if your levels are elevated.
Can high testosterone affect weight and body composition?
Yes. High testosterone can increase muscle mass and affect how the body stores fat. This is why understanding your overall health context through our free BMI calculator is helpful. Weight management for individuals with high testosterone should be discussed with your GP, as treatment of the underlying hormonal imbalance is also important.
Is high testosterone more common in men or women?
High testosterone (above normal range) is relatively rare in men but more commonly seen in women, particularly in those with PCOS (polycystic ovary syndrome). Women with PCOS may have testosterone levels 2–3 times higher than normal, leading to symptoms like excess hair growth and irregular periods.
What should I do if I think I have high testosterone?
Contact your GP and describe your symptoms (irregular periods, excess facial hair, acne, infertility, mood changes, etc.). They can arrange a blood test to confirm testosterone levels. If elevated, your GP may refer you to an endocrinologist or hormone specialist through the NHS for further investigation and treatment.
Can lifestyle changes help manage high testosterone?
Yes, for some conditions like PCOS, lifestyle changes including weight management, regular physical activity, balanced nutrition, and stress reduction can help. Work with your GP or NHS services to create a plan. Our progress tracker can help you monitor changes over time alongside any medical treatment recommended.
