Choáng nhẹ, chớ xem thường
ôi khi đang làm việc, đứng lên, ngồi xuống, bạn cảm thấy choáng, chóng mặt. Cơn choáng có thể xảy ra trong chốc lát và sau đó hết, rồi bình thường trở lại đã khiến nhiều người chủ quan, dễ bỏ qua triệu chứng này. Nguyên nhân gây choáng có thể do lượng máu cung cấp lên não giảm nhanh chóng, người bị thiếu máu do thiếu sắt vì chế độ ăn quá nghèo dinh dưỡng, người mắc bệnh tim cũng hay gặp choáng. Nếu cơn choáng tái diễn nhiều lần có thể là dấu hiệu của rối loạn chức năng thần kinh.
