Summary

A new study links GLP-1 drugs like Ozempic to serious eye conditions, including nonarteritic anterior ischemic optic neuropathy (NAION), which can lead to blindness.

Researchers reviewed nine cases where patients developed vision problems after starting semaglutide or similar medications.

While the study does not prove causation, scientists suspect the drugs may contribute to these issues by rapidly lowering blood sugar or affecting optic nerve cells.

Experts call for more research and suggest that adjusting dosage rates might help mitigate potential risks for high-risk patients.

Just gonna be blunt and say that this is a pretty shitty misconception, like saying cancer sufferers didn't pray hard enough or something.

I'm T2D. I'm not going to provide my "fitness creds" (because why would you believe me anyway) but I'll just say it's absolutely not possible that my T2D is caused by poor diet or lack of exercise.

T2D is caused by insulin in insufficient quality or quantity. The pancreas produces insulin. Some people just have a shitty pancreas that produces shitty insulin that doesn't work. If you're overweight then fatty pancreas makes it worse, but it's not the underlying cause.

If you have T2D you can't store glucose effectively, it hangs around in your blood and fucks everything up. Consequently you shouldn't consume carbohydrates which your liver covers to glucose.

T2D is not caused by the consumption of sugar, but people with T2D cannot process sugar.

For a newly diagnosed person with T2D, diet and exercise is indeed the first recommendation, because the meds suck and losing some weight might make smaller doses more effective.

I, and others like me, lost the genetic lottery. I have to stick to an incredibly restrictive diet, and bullshit exercise regime, to delay the inevitable deterioration of my health. Even so I will be lucky to live to 60, and if I do ill probably have ass cancer or amputations or dead kidneys or some other fuckery.

Honestly, stick your "diet and lifestyle" misconceptions up your jumper.

Pretty sure T2D is reversible with diet and exercise. It's not like T1D. It absolutely is brought on by obesity.

It's pretty well known at this point that if you have T1D your in the "need meds" camp. If you have T2D you're in the "lose weight" camp. There's tons of research on this and a ton of people who lose the weight and the T2D goes with it.

It's not a misconception just not a 100% rule.

I have high blood pressure and can't fix it with diet and exercise either, was underweight and a runner, now healthy weight yoga & lifting, have been vegetarian and omnivore, it doesn't affect it at all. Drugs work so I take them. But it's also true that people who are fat or inactive can reduce their blood pressure and blood sugar by getting in shape, it is usually a lifestyle thing.
