Feeling dizzy when you stand up could be an indication of an impending heart ailment

Sudden Dizziness – Make Sure It Is Not Your Heart

It is not uncommon for people to feel sudden dizziness when they stand. In fact, almost every person experiences this sort of dizziness sometimes. Medically, this kind of dizziness is called Orthostatic Hypotension (OH) and it happens due to a number of reasons.

However, one of the ignored yet important implications of this sudden dizziness is a weak heart. Momentary dizziness is often an offshoot of a sudden drop in blood pressure. When you change your action, such as standing from a sitting position, there is a slight increase in the rate of your heartbeat in order to compensate for the additional energy requirement. The increase, however, is not much and only in the range of 8 to 10 heartbeats per minute.

Heart Health Trivia

Heart diseases are the topmost killers in the world

n an average, human heart beats 100,000 times a day pumping out 2000 gallons of blood that flow over a length of 60,000 miles of blood vessels

Subsequent to this increase, blood vessels constrict in order to pump blood more forcefully to the brain. This gush of blood to the brain prevents dizziness when there is a change of action. In case your heart does not pump additional blood to the brain, you feel dizzy, indicating that your heart is not working as it ideally should.

The other reasons that can lead to dizziness are dehydration, low blood pressure and intake of certain kinds of medication.

Research findings reinforce the associated risk

Recent studies on Orthostatic Hypotension(OH) have proven that dizziness could be indicative of heart problems in the future. In the research conducted at UNC-Chappel Hill, researchers registered blood pressure when volunteers were lying down and immediately after they stood up. All the volunteers were followed for 17 years in order to evaluate their heart health.

The results showed that people who experienced dizziness developed higher risks of cardiac illnesses when compared to those who did not feel giddy on standing. The results remained consistent even after considering other essential influencing factors such as inherent diseases and blood pressure.
OH could indicate that a person suffers a condition known as atherosclerosis, which could lead to heart failure.


A mild degree of dizziness is not a cause of concern since dehydration, extreme hot weather conditions, stress or natural low blood pressure can be the cause of problem.
However, if the dizziness is severe, you need to be careful about your heart and get yourself tested. You should also consider taking a medical test if you develop OH severely and suddenly, without having any prior history of the condition.

Orthostatic hypotension is not conclusive proof that you face impending heart risks. However, it definitely is a sort of hint and reason enough for you to keep track of your cardiac health. Being forewarned is definitely an advantage when it comes to risk of heart illnesses. If you feel dizzy, be on your guard so that you can be healthy for long.
