Low Energy: Causes, Symptoms & Treatments
at Omniya Clinic in London
Feeling constantly tired, foggy, or unmotivated can affect everything – your mood, productivity, and relationships. At Omniya Clinic in Knightsbridge, we understand how draining persistent fatigue can be. Our medical team takes a root-cause approach, looking beyond symptoms to uncover what’s really depleting your energy.
Low energy (also known as fatigue) is common and often has treatable causes. Hormones, thyroid function, nutrition, stress, poor sleep, low iron or B12 levels, and certain medications can all contribute to feeling "run down."
Your clinician will review your symptoms, lifestyle, and medical history, then create a targeted plan, whether that’s HRT, TRT, thyroid optimisation, nutrition support, or IV therapies, to help you regain energy safely and sustainably.
What is Low Energy (Fatigue)?
Low energy, often referred to as fatigue, is a persistent sense of physical or mental exhaustion that doesn’t improve with rest. You may feel flat, unfocused, less resilient, and simply "not yourself."
It’s more than just being tired after a long day. Fatigue can sap motivation, concentration, and emotional balance, affecting how you function and engage with life. While busy schedules or stress can contribute, ongoing low energy usually signals an underlying imbalance that’s worth investigating.
Common contributors include hormonal changes, thyroid dysfunction, nutrient deficiencies, poor sleep, or chronic stress. At Omniya Clinic, we take a medical, root-cause approach to uncover why you’re feeling depleted and create a personalised plan to restore your energy, clarity, and drive.
Common Causes of Low Energy
Low energy can develop for many reasons, from hormonal imbalances and nutritional gaps to lifestyle pressures and medical conditions. Understanding the cause is the first step toward restoring lasting energy and focus.
Symptoms of Low Energy
Low energy (fatigue) can affect both the body and mind, showing up as more than just tiredness. You might notice changes in focus, motivation, and even how your skin looks and feels. These symptoms can develop gradually, often becoming "the new normal" until energy levels are properly assessed and restored.
Common symptoms of low energy include:
These signs may range from subtle to severe and can impact productivity, confidence, and quality of life.
Seek urgent medical help if you experience chest pain, breathlessness at rest, fainting, severe new headaches, or sudden weakness, as these may indicate a more serious underlying issue.
What Treatments Are Available For Low Energy?
Self-Care Foundations
When you’re feeling drained, small daily habits make a big difference. Consistent, low-effort changes can help restore balance, stabilise energy levels, and support any medical treatment you’re receiving.
Aim for a regular sleep schedule – ideally going to bed and waking up at similar times each day. Create a calming wind-down routine, reduce screen exposure and bright light an hour before bed, and set a caffeine curfew in the afternoon to improve sleep depth and recovery.
Include protein with every meal to stabilise blood sugar, pair it with fibre-rich carbohydrates, and stay well-hydratedthroughout the day. Try to limit alcohol during the week, as even small amounts can disrupt sleep and energy metabolism.
Gentle, consistent activity improves circulation, metabolism, and mood. Aim for daily low-to-moderate movement – such as walking, yoga, or swimming – and add two strength-training sessions per week if possible to build endurance and support hormone health.
Stress drains energy as much as lack of sleep. Short, frequent breaks work best: try paced breathing, mindfulness, or a brief walk between tasks to reset the nervous system. Little and often goes a long way.
These self-care foundations complement the medical and hormonal Advanced Treatments (dhaestheticsclinic.com) available at Omniya Clinic in Knightsbridge, helping you feel clearer, calmer, and more resilient day to day.
Low Energy FAQs

Tesosterone replacement therapy treatment shouldn’t be given to individuals with a diagnosis of prostrate or blood cancer. A thorough medical history and investigations will be carried out prior to the commencement of any treatment at Omniya Clinic.
Not necessarily. Ageing can change hormones and sleep, but persistent fatigue usually has specific, addressable drivers.
We use targeted bloods (thyroid, iron/ferritin, B12, vitamin D, glucose/HbA1c, hormones where indicated) and a clinical review of sleep, stress and medications via our GP Wellness Check.
When symptoms and test results indicate a hormonal driver and it’s safe for you. Your clinician will discuss benefits, risks and alternatives.
They can support hydration and micronutrient status, but long-term improvement comes from addressing the root cause (hormones, thyroid, iron, sleep, stress, metabolism). IVs are an adjunct – not a replacement for diagnosis.
Some people notice changes within weeks; deeper hormonal, thyroid or iron corrections can take longer. We review and adjust so progress is steady and sustainable.
