Feeling Off? It Could Be Your Testosterone. Here’s How to Know for Sure.

By Dr. Raphael Olaiya, GP and TRT Doctor (GMC No. 7492303)

Are you feeling tired all the time? Has your get-up-and-go got up and gone? You’re not alone. Millions of men in the UK experience a dip in their energy, mood, and libido as they get older. While it’s easy to dismiss these changes as a normal part of ageing, they could be a sign of something more: low testosterone.

Testosterone is the primary male hormone, and it plays a vital role in everything from muscle mass and bone density to sex drive and mental clarity. When your levels are low, it can have a significant impact on your quality of life. In the UK, it’s estimated that 8-12% of men aged 40-69 have testosterone deficiency (TD). That’s a significant number of men who could be feeling better and living fuller lives.

The Silent Epidemic: Are You Experiencing Symptoms of Low Testosterone?

Low testosterone can manifest in various ways, and the symptoms are often subtle and easily overlooked. Do any of the following sound familiar?

• Low Libido: A noticeable decrease in your sex drive. In fact, 31% of men with TD symptoms report low libido.
• Erectile Dysfunction: Difficulty achieving or maintaining an erection. This is reported by 27% of men with TD symptoms.
• Fatigue and Low Energy: Feeling constantly drained, even after a full night’s sleep.
• Loss of Muscle Mass: Finding it harder to build and maintain muscle, even with regular exercise.
• Increased Body Fat: Gaining weight, especially around the midsection.
• Mood Swings and Irritability: Feeling more anxious, depressed, or irritable than usual.
• Brain Fog: Difficulty concentrating and a general lack of mental sharpness.

If you’re nodding along to any of these, it might be time to investigate your testosterone levels. The good news is that you don’t have to suffer in silence.

Don’t Guess, Test: The Importance of a Proper Diagnosis

Self-diagnosing based on symptoms alone is not enough. The only way to know for sure if you have low testosterone is to get tested. A simple blood test can measure your testosterone levels and give you a clear picture of what’s going on inside your body.

Unfortunately, getting a diagnosis isn’t always straightforward. In the UK, only 7% of individuals expressed satisfaction with their access to low testosterone resources. Many men are left feeling frustrated and unheard.

That’s why we’ve made it easy to check your levels from the comfort and privacy of your own home.
