A Root-Cause Approach to Long Covid Recovery with Mosaic Medical
What Is Long Covid?
Long Covid (also known as Post-Acute Sequelae of SARS-CoV-2 Infection, or PASC) describes a collection of symptoms that persist for weeks or months after the initial Covid-19 infection.
These symptoms can affect multiple systems in the body — including cardiovascular, neurological, immune, and respiratory — and vary in severity between individuals. For some, Long Covid is a fluctuating condition that significantly impacts daily life and makes recovery feel uncertain.
- Extreme fatigue or exhaustion
- Brain fog or difficulty concentrating
- Shortness of breath or chest tightness
- Muscle and joint pain
- Headaches or migraines
- Heart palpitations or racing heart
- Sleep disturbances or insomnia
- Anxiety or depression
- Digestive issues (diarrhoea, bloating, constipation)
- Loss of smell or taste
- Exercise intolerance or post-exertional malaise
Conventional treatment often focuses on symptom management (for example, medication for pain or sleep, breathing exercises, or physical therapy). While these can help, they rarely explore why symptoms persist or how to support the body’s recovery mechanisms.
Our Functional Medicine Approach
At Mosaic Medical, we take a root-cause approach to Long Covid recovery. We aim to understand the underlying drivers of your ongoing symptoms and design a personalised plan to restore balance and support healing.
- Immune system dysregulation and chronic inflammation
- Viral reactivation (such as Epstein-Barr or CMV)
- Hormonal imbalances (thyroid, cortisol, sex hormones)
- Gut health issues (dysbiosis, SIBO, intestinal permeability)
- Neurological dysfunction (brain fog, sensory changes)
- Detoxification and oxidative stress
- Mitochondrial health and energy production
- Adrenal and nervous system resilience
- Blood clotting issues
- Post-viral autoimmunity
- Advanced lab testing (immune function, viral load, inflammatory markers, gut health)
- Targeted nutrition (anti-inflammatory diets, antioxidant support, mitochondrial nutrients)
- Supplement and herbal protocols (e.g. vitamin D, glutathione, curcumin)
- Stress regulation (mindfulness, meditation, breathwork, pacing strategies)
- Pacing guidance to avoid post-exertional crashes

FAQ – Long Covid & Functional Medicine
What is Long Covid, and how does it affect the body?
Long Covid refers to ongoing symptoms after Covid-19 infection. It can affect the immune, cardiovascular, neurological, hormonal, and digestive systems.
How can functional medicine help with Long Covid recovery?
We investigate the underlying drivers of your symptoms — from immune imbalance to viral reactivation or mitochondrial dysfunction — and create a plan that supports recovery across all systems of the body.
Do you offer lab testing for Long Covid?
Yes. We use advanced testing for immune markers, inflammatory load, viral reactivation, gut health, and hormones to guide personalised treatment.
Can Long Covid symptoms be fully reversed?
Many patients experience improvement with the right approach, though recovery can be gradual. Each person’s journey is unique, and we support you step by step.
How long does it take to see improvement?
Some patients notice changes within weeks, while others require months depending on symptom severity, duration, and underlying health. We aim for steady, sustainable progress.
Do you offer remote consultations?
Yes. We work with patients virtually across the UK, with in-person appointments if clinically required.
How do appointments work?
Your first appointment is 90 minutes, with your doctor reviewing your case beforehand. Together, we’ll identify likely root causes, discuss testing if needed, and create a plan to support recovery.
Does the appointment price include testing?
No. Testing is separate, and we only recommend it when results will change your management plan.
I already have test results and a diagnosis – can you still help?
Yes. You can upload your results before your consultation. If there are many, there may be a small preparation fee, but this will always be discussed with you first.
