Ongoing tiredness can affect your mood, focus, and motivation, but in most cases, it has identifiable and treatable causes. Factors such as hormonal imbalance, thyroid function, iron or vitamin B12 levels, sleep quality, nutrition, stress, medications, and metabolic health can all contribute to low energy.

At Omniya Clinic in London, we take a medical, root-cause approach. Your clinician will assess your overall health, identify what’s driving your fatigue, and design a personalised treatment plan to help you restore energy, mental clarity, and resilience, safely and sustainably.

What is Tiredness (Fatigue)?

Fatigue is a persistent feeling of physical or mental exhaustion that doesn’t fully improve with rest or sleep. You may feel flat, foggy, or less resilient, as though you’re constantly running on empty.
While busy schedules and stress can certainly contribute, ongoing tiredness often points to an underlying imbalance, such as issues with hormones, thyroid function, nutrition, or metabolism.

Identifying the root cause is the first step toward meaningful, lasting improvement.

Common Causes of Tiredness

Tiredness can stem from many overlapping factors, often more than one at a time. At Omniya Clinic, we investigate your hormonal, nutritional, and lifestyle profile to pinpoint what’s driving your fatigue.

Hormonal changes

Perimenopause and menopause (oestrogen and progesterone fluctuations)
Low testosterone in men, and sometimes in women
Underactive thyroid (hypothyroidism)

Nutritional and metabolic factors

Low iron or ferritin, vitamin B12, or vitamin D
Blood-sugar dysregulation, insulin resistance, or weight gain
Dehydration, or diets low in protein and fibre

Lifestyle and sleep

Poor sleep quality, irregular sleep times, or sleep apnoea
Long-term stress, anxiety, or low mood
Alcohol excess, smoking, or low physical activity

Medical and medication factors

Post-viral fatigue or chronic inflammation
Side-effects from certain medicines (e.g. for blood pressure, mood, or allergies)
Long-term conditions such as diabetes

Seek urgent medical help if you experience chest pain, breathlessness at rest, fainting, sudden weakness, or severe new headaches.

Symptoms to Look Out For

Fatigue can affect both body and mind, often building gradually. Common signs that it’s time to get checked include:

Persistent tiredness or a sense of “heavy limbs”
Brain fog, reduced motivation, or slower thinking and memory
Headaches, dizziness, muscle weakness, or slower reflexes
Irritability, anxiety, or low mood
Dark circles, a “run-down” appearance, or frequent colds and infections

If these symptoms persist for several weeks or start to affect your daily life, it might be beneficial to book a medical review. Identifying the cause early can make recovery much faster and more effective.

What You Can Do At Home

Small, consistent habits often make a noticeable difference in energy and focus. These foundations support recovery while you work on the underlying causes of fatigue:

Sleep: Keep a regular schedule, even on weekends. Aim for a cool, dark bedroom, a caffeine curfew after midday, and a wind-down routine that helps your body recognise when it’s time to rest.
Nutrition: Include protein at every meal, fibre-rich carbohydrates, and plenty of hydration throughout the day. Limiting alcohol on weeknights and ultra-processed foods can also stabilise energy and mood.
Movement: Engage in daily light-to-moderate activity such as walking, cycling, or yoga, and try to include two strength sessions per week to boost stamina, metabolism, and mental clarity.
Stress Care: Incorporate brief breathwork or mindfulness breaks, morning daylight exposure, and short walks between tasks to calm your nervous system and improve focus.
Medication Check: Never stop prescribed medicines abruptly. If you suspect a medication may be contributing to your tiredness, speak to your clinician, a simple review can often help.

How We Treat Tiredness at Omniya

At Omniya Clinic in Knightsbridge, every treatment plan is built around the root cause of your fatigue. Your clinician will combine medical insight with practical strategies to help you restore sustainable energy, focus, and wellbeing.

For Female Hormone Replacement Therapy (HRT)

When perimenopause or menopause contributes to low energy, HRT can help improve sleep, cognition, mood, and overall vitality.

Male Testosterone Replacement Therapy (TRT)

For men with clinically confirmed low testosterone, TRT can boost energy, motivation, focus, and stamina while supporting long-term hormonal balance.

Thyroid Therapy

Optimising thyroid function supports metabolism, mood, and endurance, particularly where hypothyroidism or suboptimal thyroid levels are contributing to fatigue.

GP Wellness Check

A doctor-led review with targeted blood tests, assessing key markers such as thyroid function, ferritin/iron, B12, vitamin D, HbA1c/glucose, inflammatory markers, and hormones where indicated.

Weight Management & Metabolic Support

Structured nutrition, movement, and medical support to improve insulin sensitivity, body composition, and sleep quality, all crucial for restoring daytime energy and reducing fatigue.

Comprehensive Gut Health Analysis

For patients experiencing bloating, IBS-type symptoms, or digestive discomfort, gut-focused assessment helps rebalance the microbiome, which plays a key role in energy regulation and immunity.

IV Drips (Adjunctive Support)

Intravenous formulations designed to rehydrate and replenish micronutrients. Energy and Recovery drips can provide short-term relief while you work on underlying causes.

Hormones MOT Programme

A deeper assessment of sex hormones, thyroid markers, and adrenal balance, followed by a personalised optimisation plan to support long-term vitality.

Tiredness FAQs

Is an IV drip for tiredness safe?

IV therapy is generally safe when administered by qualified medical professionals. At Omniya, IV drips are tailored to your needs and used as an adjunct to a broader care plan, not a substitute for identifying and treating the underlying cause of fatigue.

How does HRT help with lethargy and tiredness?

When tiredness stems from perimenopausal or menopausal hormone changes, HRT can make a noticeable difference. By restoring oestrogen and progesterone balance, HRT helps reduce hot flushes, night sweats, and sleep disruption — often improving overall energy, clarity, and mood.

If I stop taking TRT will I have low testosterone count again?

Testosterone Replacement Therapy (TRT) doesn’t permanently “reset” hormone production. If treatment stops, levels typically return to your individual baseline. That’s why we review your goals, results, and safety markers regularly to ensure the best long-term approach.

Can TRT be injected?

Yes. TRT can be given as injections or topical gels, depending on what best fits your lifestyle and treatment goals. Your clinician will guide you through dosing, frequency, and follow-up monitoring.

How quickly will I feel better?

Some patients report more clarity and energy within a few weeks, while deeper improvements, particularly those involving hormones, thyroid, or nutrient balance, may take a few months. We monitor your progress and adjust your plan as your body responds.

When should I see a doctor about fatigue?

If tiredness lasts more than a few weeks, affects your daily functioning, or is accompanied by symptoms like shortness of breath, chest pain, fainting, or severe headaches, it’s important to seek medical advice. Persistent fatigue often has a treatable cause.
