There has been increasing research on the role of eosinophils and connective tissue disorders. The eosinophils main role is fighting off parasitic infections, however they also play a huge part in allergic responses and inflammation. They release many cytotoxic and neurotoxic chemicals that damage foreign invaders but also your own cells / tissue.

I'm doing more research into this and may post on other threads the more I find out. Let me know if anyone else has any info on eosinophils and their roles specifically in EDS, POTS, ME/CFS, and MCAS. Also if your eosinophils ever consistently came back high on blood tests. Thanks.

Here are some studies:

High prevalence of eosinophilic esophagitis and connective tissue disorders: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3807809/
High ECP found in CFS patients: https://pubmed.ncbi.nlm.nih.gov/8738520/
On their prevalence in autonomic dysfunction / POTS: https://pubmed.ncbi.nlm.nih.gov/30851172/
Eosinophil interaction with Mast Cells: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4083463/
Eosinophilic gastrointestinal disorders and autoimmune connective tissue disease: https://pubmed.ncbi.nlm.nih.gov/26709253/

I don’t know if I have an eosinophil disorder but the one time they were measured they were high
If due to low pyruvate the red blood cell wall hardens could the eosinophils be attacking this
My Eosinophils have come up only slightly high on a couple CBCs but not all of them. It wasn't anything bad enough to alert doctors. Most of the time it's normal. However its come to my knowledge that people could still have problems with eosinophils even if they come back normal or slightly elevated. It's similar to how people can come back negative for MCAS but still have MCAS.

I'm going to be getting an Eosinophil Cationic Protein test to more accurately determine if the Eosinophils are releasing their toxic chemicals into my blood stream. It's the same test in the link where ECP was found elevated in some CFS patients.

Weird, my Eosinophil count was very very high during my ME onset... But I had a parasite infection.
