Everyone feels tired now and then. Late nights, stress, and life in general can catch up with anyone. But when low energy becomes the norm rather than the exception, it’s a signal that something might be happening beneath the surface.
At Omniya Clinic in Knightsbridge, we see many patients who describe the same frustration: “I just don’t feel like myself anymore.” Energy is low, motivation dips, and even after rest, the fatigue lingers. When tiredness persists despite good sleep, nutrition and lifestyle, it may just be a sign that your body needs a little extra support in finding its balance again.
Understanding Fatigue: A Medical Perspective
Fatigue isn’t the same as ordinary tiredness. In medical terms, fatigue is a persistent, often debilitating lack of physical or mental energy that does not improve with sleep or rest. It can make even simple tasks feel overwhelming and may last for weeks or months.
Clinically, fatigue is considered a non-specific symptom: it can arise from multiple causes, including nutrient deficiencies, infection, chronic inflammation, or hormonal imbalance. The key to effective management lies in identifying the root cause.
Doctors typically divide fatigue into:
- Physiological fatigue, caused by reversible factors such as poor sleep, dehydration, or overexertion.
- Pathological fatigue, linked to underlying conditions such as anaemia, thyroid dysfunction, or hormonal imbalance.
At Omniya, we approach fatigue as an important diagnostic clue, not something to be brushed aside.
When “Normal Fatigue” Becomes a Clinical Sign
Feeling tired occasionally is part of life, but persistent fatigue that affects concentration, motivation, or mood deserves medical attention. Tiredness can stem from a wide range of causes, from simple dehydration to complex metabolic changes. The most common non-hormonal causes include:
- Poor sleep quality or sleep apnoea
- Nutritional deficiencies (iron, B12, folate, or vitamin D)
- Chronic stress and elevated cortisol levels
- Poor blood sugar regulation or insulin resistance
- Thyroid disorders or autoimmune disease
At Omniya, our medical assessment starts with these fundamentals. Once lifestyle and nutritional causes are ruled out, we often turn to hormonal evaluation, since endocrine imbalance is a frequently overlooked factor in ongoing fatigue.

The Hormonal Connection: Why Energy Depends on Balance
Your hormones are chemical messengers, controlling metabolism, sleep, mood, motivation, and how your body uses energy. Even small disruptions in this finely tuned system can lead to a cascade of symptoms.
For Men: Low Testosterone (Hypogonadism)
Low testosterone levels are a common yet under-diagnosed cause of fatigue in men. Testosterone isn’t just about libido. It supports red blood cell production, muscle tone, cognition, and mental drive.
Men with low testosterone often describe:
- Feeling “flat” or unmotivated
- Poor recovery after exercise
- Loss of strength or muscle mass
- Low mood or irritability
- A sense of chronic tiredness, even after rest
If these sound familiar, it may be worth exploring whether Testosterone Replacement Therapy (TRT) is appropriate.
Our TRT doctors take a medical approach, with full blood testing (including free and total testosterone, SHBG, LH, FSH, and thyroid hormones) before any treatment is considered. TRT can restore energy, focus, and physical vitality when deficiency is clinically confirmed.
For Women: Perimenopause, Menopause and Adrenal Fatigue
For women, the conversation often centres around fluctuating oestrogen and progesterone levels. During perimenopause or menopause, these hormonal shifts can significantly affect energy, sleep, and mental clarity.
Other endocrine factors, such as low thyroid function or adrenal dysregulation, can also contribute to that feeling of constant tiredness.
Our Female Hormone Replacement Therapy (HRT) programmes are tailored to restore balance safely and effectively, helping women regain their energy, focus, and sense of wellbeing.
How We Diagnose Hormonal Causes of Fatigue
At Omniya, we combine medical diagnostics with a functional, whole-body approach. That means understanding why your energy is low, not just treating the symptom.
Our assessment may include:
- Comprehensive consultation: reviewing symptoms, lifestyle, stress, and medical history.
- Blood testing: measuring testosterone, oestrogen, thyroid hormones (TSH, free T4, free T3), cortisol, vitamin D, ferritin, and glucose regulation markers.
- Follow-up review: your doctor explains results clearly and discusses appropriate next steps.
- Personalised treatment plan: addressing root causes through hormonal optimisation, nutrition, IV therapy, and tailored lifestyle interventions.
Learn more about this process through our Hormones MOT service, designed to assess your entire hormonal picture.
Rebuilding Energy, The Right Way
If hormones are part of the picture, restoring balance can have a profound effect. Many patients report improvements not just in energy, but in sleep, concentration, confidence, and general wellbeing.
Depending on your results, we may recommend:
- Testosterone Replacement Therapy (TRT) for men
- Bioidentical Hormone Therapy (HRT) for women
- Thyroid or adrenal support where clinically indicated
- IV nutrient therapy or vitamin injections to support recovery
- Lifestyle and nutritional adjustments guided by our team
These treatments are always doctor-led and individually prescribed, never one-size-fits-all. Our aim is to restore your baseline energy, not create artificial peaks that fade over time.
When to Ask For Help
If your energy has been consistently low for more than a few weeks, and you’ve ruled out obvious causes such as poor sleep or overwork, it’s worth booking a consultation.
Some signs that warrant a closer look include:
- Constant tiredness despite adequate rest
- Brain fog or poor concentration
- Low motivation or mood changes
- Weight gain and muscle loss
- Poor recovery after exercise
Even subtle changes can signal early hormonal imbalance, something best addressed proactively.
