If you’re on Ozempic, Wegovy or Mounjaro to lose weight or manage diabetes, you’ve probably heard plenty about the benefits. These meds have been game-changers for blood sugar control and helping people shed stubborn kilos.
But here’s something you might not have heard; new research suggests these drugs might, in rare cases, cause serious eye problems.
We’re talking about uncommon but significant side effects that could affect your sight. Knowing the signs means you can take action early and keep your vision sharp.
Why your eyes could be affected
The drugs work by controlling blood sugar and appetite, but they can also cause rapid changes in your body.
Experts believe that sudden drops in blood sugar or changes in blood flow to the optic nerve may contribute to the problem.
If you’ve already got conditions like diabetes or high blood pressure, your eyes may be more vulnerable to these changes.
Some of the issues being reported include:
- Sudden vision loss or blurry spots, which can be permanent if not treated quickly
- Swelling of the optic nerve, causing pain, blurred or patchy vision
- Dark patches or blind spots from damage to the retina
They’re rare, but if they happen, they’re serious.
Warning signs to watch for
Keep an eye out (pun intended) for:
- Blurry or dim vision
- Losing side (peripheral) vision
- Dark or grey shadows in your sight
- Trouble seeing colours
- Eye pain, flashing lights or sudden floaters
If anything changes suddenly, don’t “wait and see”. Book an urgent eye exam with your trusted optometrist. Fast action can make a huge difference.
Protecting your vision while on these meds
The good news? Most people won’t have problems — and there’s plenty you can do to protect yourself:
- Book regular eye exams every six to 12 months if you’re on these meds or have diabetes
- Tell your optometrist and GP you’re using Ozempic, Wegovy or Mounjaro
- Report any vision changes immediately, no matter how small
- Keep your health in check by managing blood sugar, blood pressure and cholesterol
Bottom line
Ozempic and other weight loss/diabetes drugs are powerful tools for improving your health. Eye side effects are rare, but your sight is too important to risk.
