Is eyelid edema a bad rest, or is the organ sick? What common sense do you know?

Many people will have this experience, that is, after a night's sleep, they wake up the next morning and find that their eyes are suddenly swollen. Is the eyelid edema a bad rest or an organ disease? Do you know why?

First of all, the occasional edema is probably due to drinking a lot of water before going to bed at night, so after getting up the next morning, my eyes will have moderate swelling. I usually drink water before going to bed at night, because if I don't drink water, I always have a dry cough. I get up at night after drinking water. I know this habit is not good, but I never thought of a good solution. There is also the problem of edema. I don't think I am swollen. Maybe I am old? Does this mean that I am young? Okay!

the second question is, if you don't drink a lot of water and your eyelids keep swelling, is it because your boyfriend punched you? If so, don't say it, you deserve it! Because you beat someone in the hospital, they still don't scratch you twice? This joke seems to be on the live broadcast. Although it is a joke, it also shows that no matter what the situation is, as long as it is swollen, there is a reason, and it will never be for no reason.

The third one is edema without drinking water, so you should really pay attention. It is likely that there is something wrong with the organs. At this time, the best way is to go to the hospital to see a doctor in time. If you think this is serious, go to a special hospital, and once again, go to a special regular hospital. Don't go to those small clinics with doors, which may be unqualified. You'd better not go to such a place, which will cost a lot of money and make a lot of crimes.
