Some people experience poor vision after eating. Shroud, not focusing, all the cases. I would like to come up with a harmless reason for such a symptom, but more often everything is bad.
As for diabetes mellitus, in this case, a horror story about visual impairment is not suitable. Well, that is, on the Internet, there is a story about the deterioration of vision from an increase in blood glucose levels. Only this increase should not be just after eating, but in a couple of weeks sooner.
In diabetes mellitus, the most serious cause of visual impairment is glucose damage to small blood vessels in the retina. This is very bad. You can go blind.
But the less terrible, but the most common cause of visual impairment in diabetes mellitus is the swelling of the optical media of the eye under the influence of glucose.
You all heard about glycated hemoglobin. We have already discussed it here a couple of times. And we discussed that blood glucose can impregnate not only hemoglobin, but many other things as well.
In particular, elevated blood glucose levels cause sugar to get stuck even inside the transparent filling of the eye. Sugar pulls water on itself, and the eye swells slightly. In this form, it is more difficult for him to focus on something, and vision deteriorates.
Therefore, people with diabetes can order new glasses only after they have properly monitored their blood sugar levels for a month. Otherwise, there will be an error in optometry.
This was the same story about the deterioration of vision from high blood glucose levels. But such a harmful effect does not develop in the afternoon, but in a few weeks. So it doesn't fit our topic.
The option with robbery is more suitable for us. If an atherosclerotic plaque has settled in the carotid artery, which greatly interferes with blood flow, then after food, the remnants of blood will not go to the brain and not to the eyes, but will remain in the stomach, supporting digestion. This sharply deteriorates vision. This is rare and bad. It is easy to die from this stenosis of the carotid artery.
In parting, I will give you one less terrible option, which we have already sorted out. It's simple light-headedness after a sudden transition to an upright position in the first 90 minutes after eating. The eyes may darken as before fainting. This is the most harmless thing that I can offer you. Sorry!
