There’s been some interesting research done in to long covid over the last year or so. It has been so hard to define as people will have a different group of symptoms depending on how covid has attacked their body.
Scientists know that covid can affect your heart, which explains the heart problems, chest pain, palpitations and sometimes the fatigue that people feel:

And it can affect blood vessels, leading to POTs, dizziness etc:

Lung damage can be seen on specialised scans on long covid patients:

It can affect the immune system:

And it can affect your neurological system.

And cause microclots:

From the Forbes article:
“The plight of long haulers was dismissed early on in the pandemic, often leaving sufferers to deal with life-altering symptoms on their own, without clinical or institutional support. This analysis by Phetsouphanh et al. helps firmly ground their experiences in biology. Long Covid is a medical condition, often debilitating, and has to be treated as such.”
I think people tend to see long covid as some kind of wishy-washy fatigue that can’t be defined, hence thinking it’s easy to fake. However, all of the problems above (heart, pots, immune, neurological etc) are all measurable. Like the article says, there are bio markers, damage is visible on scans or in blood tests and sometimes the physical changes can be seen with the naked eye.
Unfortunately for long covid patients some of the technology that detects these symptoms isn’t easily available on the NHS, or widely understood yet by GPs. I hope awareness continues to be raised for the sake of not only long covid patients but those with ME/CFS, lupus, PVS and similar who have been battling this lack of understanding for years.
