Bad eyesight after sugar binge?

Answered on August 19, 2014
Created January 19, 2011 at 3:48 PM

Last night I had yet another sugar binge... I am still learning how to deal with it. I had a craving for popcorn and figured it wasn't THAT bad for paleo. All of a sudden I wanted more and more carbs. Didn't turn out so well for me hahah.. This morning I woke up and it seems like I NEED to wear my glasses to read this website. I usually don't have to wear my glasses but it makes everything a little bit clearer. Has this happened to anyone? Also does paleo help your eyesight?

You could try drinking it without sugar, and try half-caff (I know it sounds scary, but if you cut back a bit on the caffeine, and add another stimulant like Siberian Ginseng extract or a cup of salty broth, it can totally work and you won't miss the extra caffeine). Sensitive folks can get vision changes from both caffeine and sugar because of a quick bump in blood glucose or blood pressure.

^^^^^^ +1. Check you're blood sugar with a meter if this continues... First thing in the morning, just before a binge, and every 15 minutes afterwards for 2 hours.

There is no way to know you don't have diabetes without testing, you need to investigate this with a doctor. Even slightly blurry vision after ingesting more carbs than you can process is not to be taken lightly.

You might want to check your blood sugar. My eyesight changed when I was diagnosed with type 1, but corrected itself when my blood sugar was normalized.

yeah I don't think I have insulin resistance.. I am pretty lean and only 20 years old. But I am dehydrated.. maybe that has something to do with blurry vision?

I work at an Optometrists office, and a persons blood sugar definitely can affect their vision. In fact, sometimes a change in vision can be one of the first indicators of insulin resistence or diabetes.

Blurry vision after overdoing processed carbohydrates is quite common. It IS a sign of insulin resistance. Just because you are young and lean doesn't mean insulin resistance cannot happen. The blurry vision is just another indication of being in a carbohydrate brain "fog". Other people who experience this tend to make decisions slower, are a bit more forgetful, take longer doing regular tasks, find themselves much more fatigued, etc.

Dehydration will just make things worse. Dehydration, by itself, unless severe (and I mean severe like soldiers experience in war zones with high heat), won't do much to affect blurry-ness. Dehydration can make your eyes hurt, and make you want to blink a lot or keep them closed.

You might want to get an OGTT and see what happens when you ingest a lot of glucose and see how your insulin responds. OR, you might want to look into why you binge, so you can stop doing it.

I am diabetic and this is a symptom of high blood glucose. I agree that it may be worthwhile investing in a blood glucose monitor or asking for a glucose tolerance test.

I was diagnosed with diabetes aged 27, but I started to gain weight at 17 - all blood tests came back negative for diabetes. I was diagnosed with an OGTT even when blood tests still came back negative.

The blurry eyes are a diabetic complication & can lead to retinopathy. Non-diabetics can also suffer from retinopathy - have a look at diabetes101.

I never would have guessed that this would occur as a result of a one-time binge, but obviously degeneration of the eyes is concomitant with diabetes.

If you're having trouble with cravings, try at first to replace these foods with fruits, and then eventually phase out the fruits in favor of starchy tubers. There is evidence however that leaving anything sweet in your diet is going to undermine your ability to free yourself completely. That being said, binging on blueberries isn't really going to be all that bad.

I think I know what you mean, and have experienced similar things. Loren Cordain has a interesting paper on myopia and chronic hyperinsulinemia, but I think he talks about the long term effects.

I know I'm late but wanted to tell you what has helped me from having those carb cravings. I recently been taking magnesium and chromium supplements and they really seem to be helping, finally am feeling that full feeling that I never gotten no matter how much I ate. Maybe they can help you guys, do a search on magnesium and cravings you will find a lot of information on it.

I haven't officially even started Paleo yet...just learning about it. But I suffer from insulin resistance due to PCOS, and my fasting glucose in recent blood tests show I'm in the pre-diabetes range. I have been making healthy changes to my diet for the past two months, including giving up fast food and soda. I was a Coke addict.

Today I drank some Pepsi at my Mom's while doing housework. I knew it was a bad idea, and I didn't enjoy the taste, but I started binging on it. I drank about 3 tall 12 oz. glasses of it this afternoon/evening. My heart's been racing off and on, and I also notice my vision is really blurry tonight. I've worn glasses for many years, and my eyes seem to be deteriorating, including atrophy in my left eye.

Since I'm paying attention to how food affects me now that I've began to clean up my diet and be more mindful, I am really sensitive to the sugar/eye connection. Just as diabetics experience blood sugar spikes, my insulin resistance due to PCOS mimics the same symptoms, including the blurred vision. Just one more reason not to give in to sugar cravings!

I have had the same experience. My vision is usually significantly worse for about 24 hours after a severe sugar binge.

I had a similar experience even when I ate a whole foods vegan diet. Even though I ate a lot of grains, I only got about 40% of my calories from carbs, rarely ate sugar.

On my birthday I went out for pizza with my family and ate a huge pizza (Just sauce and spices, veggies), a local sugar filled ginger-ale, then went home and had a huge helping of chocolate cake. That night must have been probably 80% carbs.

By the time I'd gotten home, even before the cake, I felt stoned, vision was extremely bad, and I could hardly think, much less concentrate.

Even so I still continued to binge on carbs, for the next 2months. Only recently has it stopped. The only way to control it, in my experience, is to not even start. All the willpower in the world can't stop a carb binge once the seed's been planted.

I do not have high blood pressure (typically 110/70), and I have this happen to me too. For breakfast this morning I had a coffee (with 1/2 tsp sugar) and a couple pieces of french toast (made with whole grain kamut bread) but I used syrup. Now I have to wear my glasses to read b/c my eyes won't focus sharply. It doesn't always happen to me, but occasionally. I don't have diabetes, but pre-insulin resistance is possible... I'm due for my physical....

i too rarely eat white sugar. but since i grew up eating so much of it, my body has an addiction to it. so when i eat a little, it is hard to stop. i just ate a few sugar-filled pastries and about 25 minutes later noticed my vision got worse. i had never noticed it so clearly before to happen... but before i said anything to anyone around, i ran to the computer and typed "sugar eyesight". turns out its true that white sugar blurs vision. of course this is no scientific test, but i do scientific tests on myself. for example if i didnt eat dairy for a while and then ate a large piece of cheese, i notice the effects. nowadays i don't eat dairy because of that. and so on and so forth, im learning to be perceptive and figure out how things REALLY effect me as opposed to how i was taught, told, or brainwashed things effect me (i.e. milk gives you calcium and is good for your bones... well, then why is it that america as the most milk/dairy consuming country has the highest rate of osteoporosis etc)
