Yes, it is possible for you to get the nausea after the cataract surgery. After the cataract surgery, there are many side effects, including the headaches. The nausea may be caused by the headache. However, you should better have the good care for the eyes after the cataract surgery. Or else, it may leave many problems.
Well, in my opinion, I do not think the nausea can be caused by the cataract surgery. First, you should know that nausea is the sensation of unease and discomfort in the upper stomach and head with an urge to vomit. So we can say that it is a kind of problem which is about the stomach. Generally speaking, alcohol, or stress are the causes which can lead to it. So there is nothing to do with the cataract surgery. But if you have taken surgery, there are many tips you should pay attention to. For example, you should not watch TV or computer in the first week, and also should be careful when you have shower. For foods, you should eat foods high in beta-carotene, Vitamin C and Vitamin E. These substances are called antioxidants, and most of the nutritional components of cataract prevention and reversal are related to boosting antioxidant levels.
