This is apparent from tests among patients with a mild form of Covid who were examined by Radboudumc for up to six months after infection. The results of the study have recently been published in the scientific journal Physical Therapy & Rehabilitation.
hyperventilate
The study followed 21 patients who were not hospitalized but who developed serious and long-lasting complaints. The postcovid complaints severely limit the daily functioning of these patients. Lung function, blood tests and condition of the patients were completely normal, but about all patients showed abnormal breathing in cycling tests. They also have breathing problems in daily life. Most hyperventilate. This can lead to fatigue, chest pain, dizziness and headaches.
sensors
The reason for the disturbed breathing is not yet clear, the researchers say. It looks like a problem in the control from the brain. They receive too many signals from sensors, causing patients to breathe more than necessary. A disturbed metabolism in the muscles can also have an influence. Stress can also be involved.
Because the respiratory symptoms are very similar to those in a chronic hyperventilation syndrome, the treatment of post-covid symptoms should also focus on this, states Radboudumc. Targeted breathing therapy from a physiotherapist seems to help, the study of 21 patients showed. This effect deserves further investigation.
