Dizziness can be caused by a variety of problems, including blood pressure changes, heart problems, strokes, cancers, and migraines. It can be difficult to describe, but can include symptoms such as feeling lightheaded, the room spinning, weakness, confusion, nausea, and vomiting. It can be a sign of a life-threatening condition, so seeking medical attention is advised.
Dizziness is an episode of feeling lightheaded or faint. An individual who experiences dizziness may feel as if they are close to fainting or experience overwhelming weakness. Some people also feel confused or nauseous when they feel dizzy; some even vomit. During a spell, a person may feel the room spin or have difficulty speaking, concentrating, walking, or performing ordinary tasks. These spells can be caused by a wide variety of problems, including blood pressure changes, heart problems, strokes, cancers, and migraines; medications and acute infections can also cause them.
While dizziness is common, it can be difficult to describe. This is because they can include a wide range of symptoms. For example, one person may describe dizziness as feeling lightheaded, while another may say they feel like the room is spinning. Some people may describe the spells as a feeling of being overly hot while also dealing with an overwhelming weakness. An individual may shiver or tremble when feeling dizzy or may feel nauseous; the individual’s nausea can sometimes even progress to vomiting.
Numerous diseases and conditions are associated with vertigo, and it can be difficult for a doctor to provide an accurate diagnosis if it is a patient’s only symptom. Problems that can cause dizziness include infections, low blood sugar, dehydration, and inadequate oxygen intake. Anemia, internal bleeding, and even panic disorder can also cause dizziness. Additionally, a person may have episodes of dizziness due to a heart condition, stroke, tumor, or migraine.
In some cases, age-related changes and illnesses can contribute to vertigo episodes. For example, age-related decreased exercise tolerance can cause dizziness. Age-related circulatory problems and hardened arteries can also lead to vertigo episodes. Additionally, nerve dysfunction related to other age-related conditions can cause or contribute to dizziness.
Because dizziness can develop as a sign of a life-threatening condition, health experts often advise patients to seek medical attention after an initial, unexplained dizziness. If a person has a history of vertigo episodes, but they get worse, they may do well to seek a doctor’s evaluation as well. Likewise, dizziness that occurs after a person begins taking a new medication or in combination with chest or arm pain requires medical attention. If an individual has difficulty walking or standing after an episode, this is also an indication of a serious condition that requires medical evaluation.
