Overview

Dizziness and fatigue can result from a lack of fluids or a health-related illness. According to the National Institutes of Health, dizziness and fatigue can be caused by dehydration. If you suffer from chronic fatigue syndrome or one of several types of anemia you may also experience dizziness and fatigue. If symptoms of dizziness and fatigue do not subside or get worse, contact a health-care provider.

Dehydration

If you do not drink enough you water may experience dehydration. According to the NIH, dehydration occurs when your body uses more fluids than it takes in. When your body does not have adequate amounts of fluid, it becomes difficult to carry out its normal functions. Important functions such as digestion require liquids to facilitate proper waste disposal and the absorption of nutrients. Common symptoms of dehydration include dizziness, fatigue and muscle weakness. When dehydration becomes severe there may be a noticeable decrease in the amount of sweat and urination produced. Dehydration may occur as a result of intense bouts of vomiting, diarrhea or sweating. If dehydration goes untreated complications such as kidney damage, brain swelling or hypovolemic shock -- a fatal condition that results from the lack of adequate oxygen reaching body tissue -- can result. Dehydration requires replacing lost fluids and electrolytes either through oral ingestion or intravenously--for severe dehydration.

Anemia

Anemia is an illness that has to do with the amount of red blood cells present in your bloodstream. According to Medline Plus, anemia results when a lack of adequate red blood cells in your body reduces the amount of oxygen that is delivered to your cells and tissue. If your cells and tissue do not get enough oxygen, they cannot carry out their basic functions. If you have anemia often you may feel fatigued and experience bouts of dizziness. Other symptoms of anemia include skin that is pale, frequent headaches, shortness of breath and a fast or irregular heartbeat. There are several types of anemia and each has their own specific cause. For example, sickle cell anemia happens when red blood cells take on an irregular shape and die prematurely, leaving a shortage of red blood cells. Iron deficiency anemia is a condition in which there is not enough iron in the bone marrow to produce enough hemoglobin to be used by red blood cells. Treatment for anemia depends on the particular type of anemia present. Iron deficiency requires a sufficient supply of iron--either through eating enough iron or taking an iron supplement. Treatment for other types of anemia may include vitamin B-12 supplementation or a bone marrow transplant.

Chronic Fatigue Syndrome

Chronic fatigue syndrome -- or CFS -- is a complicated condition that causes extreme bouts of fatigue due to either physical or mental activity. According to the University of Maryland Medical Center, if you have been diagnosed with CFS you may often report feeling extremely tired or sleepy even after rest. A direct cause of CFS remains unclear, but it may result because of a reaction in your body’s immune system or a viral infection. Other symptoms of CFS aside from fatigue include dizziness, unexplained weight loss, aching muscles and the inability to concentrate. You may begin to experience depression or social isolation due to the weakening effects of CFS. Possible treatments for CFS include exercise or medications such as corticosteroids.

Other Possible Causes

Other possible causes of dizziness, as reported by the National Institutes of Health, include low blood pressure, the flu, colds and allergies, low blood sugar and medications you may be taking.
