Weight loss drugs and your eyes

[cal]

Hi All:

In case you haven't seen this there are cases of people losing their eye sight when on weight loss drugs like ozempic and wagovy.  A small percentage developed NAION which stops blood flowing to your optic nerve and causes blindness.   

I guess the caution here for us maybe since we have a pre-existing condition with CRVO or BRVO we might want to avoid these drugs. 

Here is a quote:

"This is information we did not have before and it should be included in discussions between patients and their doctors, especially if patients have other known optic nerve problems like glaucoma, or if there is preexisting significant visual loss from other causes," Dr. Joseph Rizzo, the study's lead author, the director of the neuro-ophthalmology service at Mass Eye and Ear, and a professor of ophthalmology at Harvard Medical School, said in a news release.

Here is a link to the article:

Interesting.  I know of 2 young women who are taking Ozempic for weight loss.  The one just started taking it and the other has been on it for a while, & the transformation of her body is amazing.  She looks fabulous.  I’m not sure if they have any pre-existing eye conditions.  I tried to read the entire article but a pay wall kept popping up. 

I think I read where Oprah took Ozempic which explains how svelte she looks now. 

Diet & exercise is still the best option, especially for those of us who have CRVO & BRVO.

I am not sure why I didn't get the paywall but here's the article:

Patients on Ozempic are developing a rare form of sudden blindness, doctors say

• A new study suggests people on Ozempic or Wegovy may be more likely to suddenly go blind.
• The condition, called NAION, is still exceedingly rare. It's also painless and untreatable.
• Blood-sugar issues can affect our vision.

Eye doctors in Boston have started to notice a small but worrisome uptick in cases of a rare type of sudden blindness among patients taking semaglutide.

They're raising questions about whether taking Ozempic or Wegovy might be leading to more cases of nonarteritic anterior ischemic optic neuropathy, a rare condition where blood stops flowing to the optic nerve, disturbing the connection between the eye and the brain. The issue typically surfaces suddenly, without pain, and results in people waking up in the morning unable to see out of one eye.

The new investigation, published Wednesday in JAMA Ophthalmology, found that people taking semaglutide appeared slightly more likely to develop NAION than other patients with obesity or diabetes. (Semaglutide is the active ingredient in two Novo Nordisk drugs: Ozempic for type 2 diabetes and Wegovy for obesity.)

Rare, and notable

The number of patients on semaglutide who developed NAION was tiny: Out of more than 16,000 eye patients in Massachusetts included in this six-year retrospective investigation, only 37 people on semaglutide developed NAION. But that was still more than four times as many eye problems as those experienced by similar patients who were not on the drugs over the same time period. Only nine people with diabetes or obesity who were not on semaglutide developed NAION, the researchers said.

"This is information we did not have before and it should be included in discussions between patients and their doctors, especially if patients have other known optic nerve problems like glaucoma, or if there is preexisting significant visual loss from other causes," Dr. Joseph Rizzo, the study's lead author, the director of the neuro-ophthalmology service at Mass Eye and Ear, and a professor of ophthalmology at Harvard Medical School, said in a news release.

"The use of these drugs has exploded throughout industrialized countries and they have provided very significant benefits in many ways, but future discussions between a patient and their physician should include NAION as a potential risk," he added.

Pushback from Novo Nordisk

In a statement sent to Business Insider, the semaglutide maker Novo Nordisk said: "Patient safety is a top priority for Novo Nordisk, and we take all reports about adverse events from the use of our medicines very seriously."

But the drugmaker raised concerns about the ways this study was conducted, saying there were too few cases in the trial to draw meaningful conclusions and that this type of backward-looking study could never answer questions about a causal link between semaglutide and NAION.

"NAION is not an adverse drug reaction for the marketed formulations of semaglutide," the company said.

Patients with diabetes and high blood pressure have always been at an increased risk of developing eyesight issues. For example, having chronically high blood sugar can distort your eye lenses, contributing to blurry vision. (Novo Nordisk is working on another, separate study, testing whether semaglutide might be useful in treating diabetic retinopathy.) NAION is usually permanent, and there is no treatment for it.

Hello all-

I have been quiet in thia group because  I found out after joining that I have BRAO (Branch Retinal Artery Occlusion). Although, it is a bit different I learned alot from your messages.

A little background. I was diagnosed with it last year in Dec 2023 at the age of 42. No prior conditions and after full blood  work ups and MRIs all coming back negative, I know that the medication I was taking for weightloss caused it. It was Semaglutide (an Ozempic generic). So proceed with extreme caution!!!

Yes, GLP1 are not the answer. in the first place 40% of the weight loss is muscle and if you are over 40 good luck regaining that. After you get tired of being nauseous all the time and come off the drug the weight comes back in the form of fat gain, so you are really worse off for losing the muscle. Try low carb/keto or hi fat carnivore instead, my opinion
