BBC Look East - Nicola Haseler report on Long Covid and Mast Cell Activation Syndrome

This BBC Look East report explores the potential link between long COVID-19 symptoms and Mast Cell Activation Syndrome (MCAS) as well as histamine intolerance. Dr. Tina Peers discusses the hypothesis that some individuals' severe reactions to COVID-19, both acute and long-term, may stem from underlying histamine intolerance or hyperactive mast cells, which are part of the immune system. Mast cells, when triggered, release chemicals including histamine, and an imbalance or overactivity can lead to excessive inflammation and various symptoms similar to those seen in long COVID, such as chronic fatigue and pain. Dr. Peers emphasizes the need for further research and suggests using data collected from an app to better understand the potential connection between MCAS and long COVID symptoms. This approach aims to identify whether managing histamine levels could alleviate post-COVID-19 syndrome symptoms.
