Dizziness
Several things can cause you to feel dizzy and lightheaded all of a sudden. If you haven’t had enough food to eat or enough water to drink, you might feel dizzy. If you stand up too fast after sitting or lying down, you might also feel dizzy. Above all these, dizziness can be a symptom of Congestive Heart Failure; when the heart is not able to pump well, it might cause your blood pressure to drop, and when this happens, you feel dizzy. If you ever develop sudden dizziness, or you develop shortness of breath and feel you can’t explain the cause, you should see a doctor. [4]
