The following paragraphs are a brief explanation of some of the most well-known causes of dizziness and lightheadedness. The main causes of dizziness are inherited and can be either temporary or permanent. The most common causes of dizziness and lightheadedness involve side effects of drugs, fluctuations in blood pressure, pregnancy, and other illnesses. In each of these cases, dizziness occurs as a result of the body’s reactions to the medication it has been prescribed.
The most frequent and common causes of dizziness and lightheadedness are temporary conditions brought on by sickness or exhaustion. They’re often easy to identify, since the symptoms are fairly obvious – sweating, shaking, tiredness, and so on. Examples of common causes of dizziness and lightheadedness that are temporary include high blood pressure, fluid retention, diarrhea, viral infections, and the flu. High blood pressure can cause a feeling of faintness and loss of balance, usually accompanied by a feeling of nausea and vomiting. Fluid retention, which can also be caused by dehydration, can also cause nausea, vomiting, and loss of balance.
Another frequent cause of dizziness is frequent urination, which is sometimes called urge incontinence. It can be brought on by a decrease in urinary muscle tone, or by an excess of liquid in the tissues. Sometimes, when a person has frequent urination, he or she might feel dizzy, as if being flushed by the bladder. Vomiting and frequent urination can also be symptoms of a serious condition called electrolyte imbalance, which can lead to electrolyte imbalances throughout the body, including dizziness. The most common symptoms of electrolyte imbalance include tremors and tingling, vomiting, fever, weakness, and muscle cramps.
One of the more unusual but still quite common causes of dizziness is problems with blood flow to the brain. If there is a problem with the way blood flows to the brain, the nerves that allow your eyes to move may malfunction. This is called “vertigo,” and it can have several unpleasant symptoms, including an imbalance of heart rhythm, chest pain, fainting, nausea, blurred vision, and numbness or tingling in the extremities. Women may sometimes experience dizziness accompanied by labored breathing.
Other causes of dizziness and lightheadedness that do not have common symptoms are a condition known as orthostatic hypotension. With this condition, the cerebrospinal fluid that exists within the brain and spinal cord causes the spinal cord to relax to a degree that the cerebrospinal fluid can drain into the lungs, causing a drop in the blood pressure. The most common symptoms of this condition are a feeling of being out of breath that becomes more intense as it gets higher, a feeling that you are going to faint, shortness of breath, palpitations, and chest discomfort. Some people also report nausea and a sensitivity to light that may make seeing difficult.
Another set of causes of dizziness and lightheadedness are related to dehydration and electrolyte imbalance. Dehydration is one of the more common causes of the symptoms described above and usually occurs when you drink an abundance of liquids that are relatively weak in concentration (soft drinks for example). Because of the way fluids drain from the body, when you go to sleep at night you can become dehydrated. In addition, a lack of potassium in the body can also lead to the same issues as dehydration.
Medications can also be one of the causes of dizziness and lightheadedness, as many medications act differently in people with certain conditions. Some drugs cause a rise in blood pressure, which causes a rise in the amount of fluid that is excreted from the body as well. Other drugs like aspirin or certain antidepressants increase fluid levels in the blood but reduce potassium levels. While rare, some medications like lithium also have the ability to alter the brain chemistry in ways that affect the regulation of body fluids.
It is important to rule out any serious medical causes of dizziness and lightheadedness before resorting to over-the-counter medications, as the side effects from these medications can be far worse than the symptoms themselves. A doctor should be consulted if you experience severe dizziness and lightheaded feelings on a regular basis. If you suspect that your symptoms are caused by a physical problem, such as a brain tumor or low blood pressure, you should immediately see your doctor for consultation. Doctors can screen for serious problems, such as epilepsy and multiple sclerosis, which can have dangerous side effects. However, in the vast majority of cases, a simple checkup will clear up any issues and get you back on the road to normal health again.
