When you think about vision, your ability to see clearly and interpret visual information. Also known as eyesight, it's not just about reading the chart at the doctor's office—it's tied to your heart, kidneys, and even what you take every day. Poor vision doesn’t always come from aging. Sometimes, it’s a side effect of something else entirely—like a blood thinner, a diuretic, or even a supplement you thought was harmless.
Take fish oil, a common omega-3 supplement used for heart and brain health. It’s often recommended for its anti-inflammatory benefits, but it also thins your blood. That’s fine on its own. But when combined with aspirin—or worse, warfarin—it can push your INR levels, a measure of how long it takes your blood to clot. too high. High INR? That means you’re at risk for bleeding, even in your eyes. Retinal hemorrhages don’t show up on a routine eye exam unless someone’s looking for them. And if you’re on diuretics, medications that flush out extra fluid, often for high blood pressure or heart failure., you might be losing potassium and magnesium—nutrients your eyes need to function properly. Low potassium? Blurry vision. Low magnesium? Eye spasms. These aren’t myths. They’re documented side effects.
And it’s not just about what you take. It’s about what you stop taking. Ranitidine was once a go-to for acid reflux, but it was pulled because of cancer risks. Now, people switch to other acid reducers—and suddenly, their eyes feel dry, irritated, or sensitive to light. Why? Because stomach acid affects nutrient absorption. No acid, no vitamin A, no retinal health. Even stress, which triggers warts and skin issues, can worsen conditions like glaucoma. Your eyes don’t live in a bubble. They’re connected to your gut, your heart, your kidneys, your mood.
What you’ll find below isn’t just a list of articles. It’s a map. A map showing how your vision ties into blood thinners, diabetes meds, herbal supplements, and even how you buy your prescriptions online. Some posts dig into how fish oil and aspirin interact. Others show how diuretics mess with your electrolytes—and your eyesight. One explains why INR monitoring isn’t just for your heart, but for your retina too. You’ll see real comparisons: Starlix vs metformin, Flomax vs herbal options, how generic Prilosec affects nutrient uptake. No fluff. No guesses. Just facts tied to what you’re actually taking—or thinking about taking.
