Autonomic Dysfunction in Long Covid


In the wake of Covid, a significant proportion of patients have developed a range of varied and debilitating symptoms, termed long covid, or long haul covid.

Dr Lim, who leads the Imperial Syncope service, has been able to review the tilts of many patients who have presented with long covid, and these tilt data typically demonstrate autonomic dysfunction responses to covid.

Some of the most common symptoms of long covid include:

1. Fatigue
2. Palpitations
3. Shortness of breath
4. Dizziness
5. Chest pain
6. Stomach upset/regurgitation/change in bowel habits
7. Insomnia/ sleep difficulty
8. Brain fog or difficulty in concentration

Self-education is the first step, and reading the free-downloadable leaflet below may help give you an initial strategy for improving symptoms:
