When a person feels dizzy they are actually disoriented and feel as though they or their surroundings are moving. In severe cases, a person may faint. If a person experiences such extreme dizziness frequently, it indicates some underlying condition that has to be identified. Extreme dizziness may result from number of causes such as vertigo, sugar levels in blood, low blood pressure, panic attacks, poor nutrition and dehydration, or pregnancy.
Vertigo occurs due to problem in the brain (central vertigo) or the inner ear (peripheral vertigo). Peripheral vertigo can be caused by viral or bacterial infection of the inner ear. Vestibular system represents structures in the inner ear and it includes cochlea, a small chamber inside the inner ear which contains cochlear fluid. When infections spread onto cochlear fluid, the nearby nerve, called vestibular nerve cannot send proper signals to the brain. Due to these wrong signals, a person can feel confused, disoriented, and lose his or her balance. Problems with the vestibular system can be treated with vestibular rehabilitation therapy that can reduce dizziness.
Blood Sugar Levels
Normal blood sugar levels range between 70 and 150 mg. Typically, blood sugar levels are lower in the morning which can lead to dizziness. However, chronic low levels of sugar (hypoglycemia) can cause fatigue, imbalance, and falling unconsciousness. Low oxygen levels in blood can also result in dizziness.
Low Blood Pressure
Generally, low blood pressure is often associated with dizziness. Low blood pressure causes syncope, feeling of dizziness that occurs due to sudden changes in body positions. This occurs due to insufficient supply of oxygen to the brain because the heart requires more time to send the blood to the brain. Low blood pressure has to be treated with proper medications to minimize the dizziness.
Dizziness may occur due to certain mental states like depression or anxiety. Anxiety is characterized by panic attacks which is an episode of intense fear. Panic attacks result in physical reactions such as irregular heart beat that can lead to dizziness. Person that experiences panic attack also has breathing rhythm affected. Panic attack may cause shortness of breath or hyperventilation and it is recommended to do deep breathing and other relaxation techniques in such case to relieve the dizziness.
Irregular eating and consuming unhealthy foods can cause vomiting, weakness and extreme dizziness. Dizziness may also occur due to insufficient fluid intake. If dizziness is caused by dehydration it can diminish after you increase intake of water.
Hormonal changes during pregnancy often lead to extreme dizziness. This occurs because hormones contribute widening of blood vessels to ensure adequate blood flow to the fetus while return of the blood to the mother is decreased. This can result in low blood pressure that triggers dizziness.
