Why not to take lightheadedness lightly
Have you been feeling faint, dizzy, weak and light-headed quite often? Please don’t ignore it. You need to see a doctor! It can be because of something as simple as hunger or as complicated as a heart issue.
The medical term for this condition is presyncope. You almost feel like fainting with dizziness, light-headedness and muscle weakness. You can feel faint when there is a temporary fall in the flow of oxygen-carrying blood to the brain, lower than what is needed for normal functioning. However, there is no loss of consciousness.
Presyncope is not taken seriously most often. But it is important that you find out what is causing it. Even if you won’t faint, there is always a risk of falling down. Additionally, it can lead to life threatening conditions if not diagnosed in time.
Reasons why you feel faint
Normal BP is 120/80. You have low BP when the reading is 90/60 or lower. However, there are people who have low BP all the time, they don’t have any symptoms and their low BP readings are normal for them. In other people, BP drops when they sit up from a lying position or when the stand up from a sitting posture. There is dizziness only for a short period of time and BP quickly gets adjusted to the new posture and gets back to normal. This is termed as postural hypotension. This can get troublesome with advancing age, especially for people who have diabetes, central nervous system diseases and those who are dehydrated due to hot weather or less fluid intake. Another reason for your BP to drop below normal is loss of blood.
