What Is Erectile Dysfunction (ED)?

Erectile dysfunction (ED) refers to difficulty getting or keeping an erection firm enough for sexual activity. It’s one of the most common concerns affecting men’s health, and while occasional issues are normal, frequent or ongoing ED often signals an underlying, treatable cause.

Common causes of erectile dysfunction include:

Psychological factors such as stress, anxiety, or relationship tension
Hormonal imbalances, particularly low testosterone or thyroid dysfunction
Circulatory problems affecting blood flow to the penis, often linked to high blood pressure or metabolic syndrome
Medication side effects, especially from antidepressants, blood pressure tablets, or prostate drugs
Lifestyle factors such as poor sleep, smoking, excessive alcohol, or lack of exercise

Understanding what’s behind your symptoms is key, because in most cases, ED can be successfully treated with a personalised plan that restores both confidence and sexual wellbeing.

Common Causes of Erectile Dysfunction

Erectile dysfunction can result from a combination of physical, hormonal, and psychological factors. Understanding the root cause is key to restoring both function and confidence.

Physical Causes of ED

Cardiovascular health issues: reduced blood flow from high blood pressure, high cholesterol, or vascular disease can make it harder to achieve or maintain an erection.
Diabetes and insulin resistance: elevated blood sugar can damage blood vessels and nerves involved in arousal.
Low testosterone: impacts libido, energy levels, and erection quality.
Thyroid dysfunction: both overactive and underactive thyroids can reduce libido and energy.
Medication side effects: certain antidepressants, antihypertensives, and prostate medications may interfere with sexual function.
Sleep apnoea, obesity, smoking, and excessive alcohol: all affect circulation, hormones, and energy levels.

If hormones are contributing factors, we may recommend: Testosterone Replacement Therapy (TRT) to restore balance, energy, and libido. For a broader medical assessment, you can also book a GP Consultation at Omniya Clinic in Knightsbridge.

Psychological Causes of ED

Emotional and mental wellbeing play a significant role in sexual performance. Common psychological triggers include:

Stress and anxiety, which can reduce sexual arousal and focus.
Low mood or depression, often linked to reduced libido.
Relationship concerns, including communication or intimacy issues.
Performance anxiety, especially following a single difficult or stressful experience.

Many men experience a mix of both physical and psychological factors. At Omniya, our approach combines medical testing, hormone assessment, and holistic support to find the right path to recovery.

Symptoms of Erectile Dysfunction to Look Out For

Erectile dysfunction (ED) can develop gradually or appear suddenly, and the symptoms often overlap with wider issues such as hormonal imbalance, metabolic health, or stress. Recognising these signs early can help you take action before they affect confidence or relationships.

Common symptoms include:

Ongoing difficulty getting or maintaining erections, despite feeling aroused or wanting sex.
Fewer or weaker morning erections, which may signal changes in blood flow or testosterone.
Reduced sex drive and overall energy, often linked to low testosterone or chronic fatigue.
Fatigue, low mood, or brain fog, which can accompany hormonal or thyroid imbalance.
Signs of metabolic health changes, including weight gain around the middle, high blood pressure, or raised triglycerides, which can impact circulation and erectile function.

We use advanced diagnostics to identify underlying causes. Typical tests include:

Lifestyle and nutrition guidance, including structured Weight Loss Consultation for patients with insulin resistance or metabolic issues.
Management of contributing conditions, such as blood pressure, diabetes, or medication side effects.

Erectile Dysfunction FAQs

Is viagra the only drug for erectile dysfuntion?

PDE5 inhibitors like sildenafil and tadalafil can help, but ED is often multifactorial. Addressing hormones, metabolic health and stress can deliver better, longer-term results.

How long does TRT take to improve erections?

If low testosterone is the driver and TRT is appropriate, libido and energy often improve within weeks; erectile quality may take longer and benefits build with consistent therapy and lifestyle changes.

Will TRT have any other positive effects on me?

Many patients report improved energy, mood, concentration, body composition and libido when TRT is clinically indicated and correctly managed. Your response is individual and monitored.
