10 Causes of Dizziness

Nearly 40% of people over the age of 40 experience dizziness in their lifetime. Dizzy spells are uncomfortable but they are very common in adults. Vertigo is a more serious condition than ordinary dizziness and it makes you feel like the room is spinning as you stand still. This is usually caused by head movement or positioning. Several diseases of the balance organs found within the inner ear can cause vertigo. Dizzy spells can range in severity from just annoying to serious and debilitating.

Dizziness may be a symptom of a condition that is more dangerous and should be discussed with a doctor, especially if it is chronic. Medical treatment depends on the underlying cause of the dizziness. Most causes of dizziness are harmless and the problem tends to go away on its own. However, it is important not to be deterred from visiting the doctor because dizziness can sometimes be the only symptom of a serious disease that may be life-threatening.

Cause #1: Pregnancy

Dizziness is a common symptom of pregnancy. The rise in hormones that causes blood vessels to dilate, increases blood flow to the baby and lowers blood pressure as well. Women who are anemic or have varicose veins may also be more susceptible to experiencing dizzy spells. This is the reason for temporary dizziness during pregnancy.

Another cause of dizziness during pregnancy may be low blood sugar levels due to the body’s metabolism changing. This can occur in any trimester but is most common in the first trimester as the body is trying to adjust to the new pregnancy. Dizziness is also common in the second trimester when the uterus is expanding and putting pressure on surrounding blood vessels. In the third trimester, the weight of the baby on your body will press into a large vein, called the vena cava, and affect the blood that is being carried from your lower body to your heart, also resulting in dizziness.
