Researchers at the University of Cambridge have made a breakthrough in understanding the prolonged effects of COVID-19, also known as long COVID. A recent study published in Nature Immunology has identified iron deficiencies as a key factor in the extended recovery process for some patients.
The research found that individuals with low iron levels experienced increased inflammation, anemia, and disruptions in the production of healthy red blood cells after contracting the virus. This led to a direct correlation between diminished iron reserves and more severe health complications just two weeks after diagnosis, with some individuals even experiencing persistent long COVID symptoms like cognitive decline.
According to estimates from the University of Cambridge, nearly 30% of individuals infected with the SARS-CoV-2 virus could be at risk for long COVID due to iron deficiencies. Data from the CDC further indicates that almost 3 million Americans require treatment for anemia or iron deficiency annually.
Lead researcher Hal Drakesmith highlighted the serious impact of sustained iron insufficiency on oxygen transport, metabolism, and energy levels. Dr. Aimee Hanson also emphasized the importance of regulating iron levels during a COVID infection to prevent further complications.
The study’s findings have significant implications for the understanding and treatment of long COVID symptoms related to iron deficiencies. Researchers are now calling for ways to remobilize iron in the body to help patients recover more quickly and effectively from the virus. This new insight could potentially improve outcomes for millions of individuals struggling with long-lasting effects of COVID-19.
