Your tendons need estrogen to repair themselves. It's the signal that tells them to make collagen, stay strong, fix the daily wear and tear.

When estrogen's there, your body patches the damage overnight. When it's gone, the damage piles up until the whole thing gives way.

Here's the part that should make you angry:

You haven't run out of estrogen. Your body still makes it every day, even years after menopause. It's there.

But your body is throwing it away before it ever reaches your tendons.

Your gut is supposed to have a recycling system — bacteria that catch estrogen before it leaves your body and send it back into your blood. This saves 20 to 30 percent of your estrogen daily. That's exactly what your tendons need to survive.

Those bacteria are gone. And they didn't disappear on their own.

The processed food — the ready meals, sugar, preservatives — starves them.

The antibiotics your doctor prescribed over the years wipe them out alongside the bad bacteria.

And here's the one that should make your blood boil:

 The ibuprofen your doctor gave you for your hip is proven to destroy gut bacteria. 

The exact bacteria that recycle your estrogen.

Every time you take a painkiller for your hip, you're killing the bacteria your body needs to heal it.

The treatment is making the disease worse.

Doctor prescribes painkillers. Painkillers destroy gut bacteria. Gut can't recycle estrogen. Tendons starve. Pain gets worse. 

Doctor prescribes more painkillers.

Nobody connected the dots. Nobody told you the Western diet was starving these bacteria. Nobody told you the ibuprofen was the worst thing you could be taking.

That's the real cause of GT. Not ageing. Not arthritis. A recycling system destroyed by the modern world.
