Some of the conditions that may cause lightheadedness in a patient include low blood pressure, high blood pressure, dehydration, medications, postural or orthostatic hypotension, diabetes, endocrine disorders, hyperventilation, heart conditions, and vasovagalsyncope. Vertigo is most often caused by a problem in the balance centers of the inner ear called the vestibular system and causes the sensation of the room spinning. It may be associated with vomiting. Symptoms often are made worse with position changes. Those with significant symptoms and vomiting may need intravenous medication and hospitalization. Vertigo is also the presenting symptom in patients with Menieres Disease and acoustic neuroma, conditions that often require referral to an ENT specialist. Vertigo may also be a symptom of stroke. Most often, dizziness or lightheadedness is a temporary situation that resolves spontaneously without a specific diagnosis being made. Introduction to dizziness feeling dizzyDizziness is one of the most common symptoms that will prompt a person to seek medical care. The term dizziness is sometimes difficult to understand since it means different things to different people. It is either the sensation of feeling lightheaded as if the individual is weak and will pass out, or it describes vertigo or the sensation of spinning, as if the affected person just got off a merry go round. Lightheadedness is often caused by a decrease in blood supply to the brain, while vertigo may be caused by disturbances of the inner ear and the balance centers of the brain. It is important that the health care provider understand the complaint the person is experiencing. That is the first important step so that the proper direction can be taken to find a diagnosis and begin treatment. Dizziness Symptoms and Signs. Dizziness is a painless head discomfort with many possible causes including disturbances of vision, the brain, balance vestibular system of the inner ear, and gastrointestinal system. Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions such as lightheadedness, unsteadiness, and vertigo. What causes dizzinessWhile classifying dizziness into lightheadedness and vertigo categories may help understand how the body works, sometimes it is worthwhile to review common reasons why people might complain of dizziness. Low blood pressure as a cause of dizziness. Dizziness, lightheadedness, and the feeling of passing out is a common complaint in people who have low blood pressure. When the blood pressure is too low, not enough oxygen rich blood is being delivered to the brain, and its function can be affected. If the brains blood supply is decreased too much, the person may pass out syncope. Symptoms may worsen when changing position from lying down or sitting, to standing up. In addition to feeling dizzy, associated symptoms may include Low blood pressure may be the result of an underlying illness or disease, or it may be a normal physiologic condition. Some common reasons for low blood pressure include the following Anemia decreased red blood cell count due to decreased production or increased destruction of red blood cells. Bleeding may cause anemia due to red blood cell loss. Dehydration loss of water in the body often occurs with infections that cause vomiting and diarrhea. Intel Centrino Advanced N Wimax 6250. Fever also can cause a significant amount of water loss due to increased metabolic rate and excessive sweating as the body tries to cool itself. Heat related illnesses associated with dehydration such as heat cramps, heat exhaustion, or heat stroke a medical emergency. Side effects of certain medications used to control blood pressure and heart rate. Examples include beta blockers propranolol Inderal, Inderal LA, atenolol Tenormin, metoprolol, Lopressor, Toprol XL, which block adrenalin receptors in the heart and may limit the ability of the heart rate to increase in response to changes of position, decreased red blood cell count, or dehydration. Nitroglycerin and isosorbide mononitrate Imdur, a long acting nitroglycerin, are medications that are prescribed to dilate blood vessels in the heart to treat angina. However, these medications also cause other blood vessels in the body to dilate, decreasing blood pressure. Diuretics that can cause dehydration. ACE inhibitors that slow the heart rate, and. Medications for erectile dysfunction sildenafil Viagra, Revatio, tadalafil Cialis, and vardenafil Levitra, Staxyn ODT, avanafil Stendra that can dilate blood vessels. Alcohol use. Pregnancy. Postural or orthostatic hypotension as a cause of dizziness. In individuals who are dehydrated or anemic, blood pressure readings may be normal when they are lying flat however, the lack of fluid is unmasked when they stand up quickly. The lack of blood to the brain may cause dizziness and lightheadedness. This feeling may pass in a few seconds as the body adapts. However, if dehydration or medications for example, beta blockers prevent the body from reacting by constricting blood vessels and increasing the heart rate, the dizziness may persist to the point at which the patient passes out faints, or experiences syncope. Some diseases are associated with an inability to compensate for changes in body position autonomic dysfunction. Normally when a person stands, blood vessels contract to increase blood pressure slightly, and the heart rate increases to pump blood uphill to the brain against gravity. In autonomic dysfunction, a person may become dizzy when they move from a lying position to sitting or standing up. Examples of these diseases include diabetes, Addisons disease, or Parkinsons disease. Orthostatic hypotension is a common symptom with Shy Drager syndrome. Shy Drager syndrome is a rare disease in which the autonomic nervous system degenerates and cannot provide the routine control mechanisms for the body including heart rate, blood pressure, and bowel and bladder function. High blood pressure. High blood pressure, or hypertension, is known as the silent killer since it often has no symptoms, even if blood pressure readings are markedly elevated. On occasion, a person may complain of headache, nausea, or dizziness, although the complaints dont necessarily correlate with the degree of blood pressure elevation. However, if the blood pressure is elevated and the person has symptoms, there is a need to bring the blood pressure under control relatively quickly. The more severe the symptoms, the quicker blood pressure control needs to be achieved. For example, if a person is having chest pain or stroke symptoms associated with high blood pressure, the blood pressure needs to be controlled immediately hypertensive emergency. Diabetes as a cause of dizziness. Dizziness is a common complaint in persons with diabetes, and may be caused by low blood sugar hypoglycemia, high blood sugar hyperglycemia, or autonomic dysfunction see previous section. Hypoglycemia or low blood sugar hypolow glycsugar emiablood describes an inadequate amount of glucoseconcentration in the blood.
