Many people may suddenly appear dizzy and nauseous under normal circumstances. If it is not frequent, most people will not pay special attention to it. However, if there is frequent dizziness and nauseous phenomenon, we should pay more attention to it, because it is very likely that there is something wrong with the body, so what causes dizziness and nauseous?
First, it may be a virus infection. If the body is infected by virus, it is easy to have fever, which may cause dizziness and nausea. So sometimes if you have a viral cold, these things will happen.
Second, it may also be caused by anemia. If the body’s absorption of nutrition is not particularly comprehensive in daily life, it will easily lead to malnutrition, which may lead to anemia. Mild anemia may not have a particularly obvious impact, but if anemia is serious, it will easily lead to dizziness and nausea.
