Every now and then I say to myself, "Am I nuts to be trying to avoid covid infection? No one else is."

And then I think about what those scaremongering bedwetters at the British Heart Foundation say. Image
"How does Covid-19 affect your heart?
We explain what Covid-19 does to your heart and circulatory system and how it can lead to conditions such as blood clots, heart damage, palpitations and high heart rate." Image
All those things sound nice.
What's on this page.

Ooo.
Questions.

And answers. Image
"What’s the link between Covid-19 and heart attacks and stroke?
Research suggests that Covid-19 can increase the risk of heart and circulatory conditions, like heart attack and stroke, after infection." Image
"How does Covid-19
affect the heart?

It's thought that C0vid-19 may damage the
endothelium (the inner lining of blood
vessels in the body).

This damage can lead to abnormal blood
clotting, 'leaky' blood vessels and reduced
blood flow." Image
"This could be part of the reason why
people with existing heart and circulatory
conditions are at a higher risk of
complications from Covid-19."
"What other conditions can you get after Covid-19?
Covid-19 and blood clots
People who develop severe illness from Covid-19 are at a higher risk of blood clots." Image
"This is thought to be due to damage to the blood vessels, either directly caused by the virus or because of the immune system’s response to the infection.

Depending on where they are in your body, blood clots can cause serious problems."
"If a blood clot forms in the blood vessels supplying blood to your heart (coronary arteries), they can block the blood supply, causing a heart attack."
"And clots that block the blood supply to the brain can cause a stroke.

Blood clots can also cause deep vein thrombosis in the blood vessels in your leg, or a pulmonary embolism if they form in the blood vessels in the lung."
"Covid-19 and heart damage
Covid-19 can cause fever and inflammation, which places extra stress on the heart as your body fights the infection.

And if the Covid-19 infection is severe enough to damage the lungs, or a blood clot forms in the lungs’ blood vessels... " Image
"... reduce the amount of oxygen and nutrients reaching the heart.

This increased demand on the heart, paired with a lack of oxygen, can cause damage to the heart muscle.

In some severe cases, this could lead to heart failure."
"Covid-19 and heart palpitations or high heart rate
When you have Covid-19, your heart needs to work harder to pump more blood around your body to fight the infection. This can lead to heart palpitations or a high or irregular heart rate." Image
"Covid-19 and myocarditis
Covid-19 can also lead to inflammation of the heart muscle (myocarditis) and heart lining (pericarditis)." Image
"Can Covid-19 cause high blood pressure?
Some research suggests that Covid-19 could be linked to an increased risk of developing high blood pressure (hypertension).

This is a serious condition, as high blood pressure raises your chances of having a heart attack or stroke." Image
"Can Covid-19 cause diabetes?
There is evidence of a link between Covid-19 and an increased risk of developing diabetes in the weeks after infection." Image
And then I think, no, no I'm not nuts.

People don't understand that there are several real models of cumulative harm that apply to covid infections.

People don't like complex ideas, so they avoid them.

This is going to be a long thread, with several simple ideas that combine to make a big complex one.
First off, we *know* beyond all doubt that covid infections cause short term harm.
The amount of short term harm varies from person to person and infection to infection, but it's there.

Do midwives know that they're now twice as likely to be off sick with a pregnancy related disorder than before the Covid pandemic started? Image
Do nurses?
And health visitors? Image
Similar trend across all staff groups, with an apparent accelerating increase more recently. Image

I think one of the most important conclusions people are missing from the data in the recent big studies is that covid infections cause radically diverse long term effects in different age groups.
So much so that it could appear as if they've been infected with different viruses.
But it's not the virus that's different, it's the immune system, the metabolism, and the way the body repairs the damage done by the infection.

Okay folks, I'm calling it, and it's bad news:

The word mucinous is going to become much more common.

Yes, bookmark this tweet, it looks bland, but it's important.
oh, okay. I won't leave you hanging.

I've written a lot recently about how we're missing the big picture of how covid infection is doing cumulative damage to interfaces in the body - linings, membranes, barriers, walls, filters.
I don't want to rewrite that all here, but I don't want to bust the flow of this thread, so at the end of it, I'll post the thread I wrote on linings.

I know, I know, you're going to laugh at me for saying that you're more likely to have problems with cramp after you've had a covid infection, but it's all very simple science.
Loads of people have been mentioning cramp recently, and like so many other conditions, yes, covid infection makes it more likely, and makes it worse.
It's just an extra factor on top of all the normal factors for cramp.
Muscles are fussy about blood flow.
They need a steady supply of oxygen to contract and, crucially, to relax.
Covid messes with the small blood vessels that supply it, so muscles end up slightly under-fuelled, and under-fuelled muscles cramp.

Do you know which whacky loons say that covid infections increase the risk of heart disease?
The British Heart Foundation.
Do you know which antivaxers say that covid vaccines do not fully protect against infection, illness, or long term effects?
Pfizer.
Do you know which hysterical doom merchants say covid can cause long term lung damage even after a mild case?
British Lung Foundation.
