Doctors Near You for Lightheadedness in Newfoundland and labrador

Lightheadedness is a sensation of feeling faint, dizzy, or unsteady, often described as feeling as if one might pass out. Unlike vertigo, which involves a spinning sensation, lightheadedness typically does not affect balance significantly but can still cause discomfort and concern. The sensation may come on suddenly or gradually and can vary in intensity. Lightheadedness can result from various causes, including dehydration, low blood sugar, sudden changes in posture (such as standing up quickly), and prolonged standing or overheating. It can also be a side effect of certain medications, like blood pressure medications or antidepressants. More serious causes may include heart conditions, such as arrhythmias or heart attack, anemia, neurological disorders, or anxiety and panic attacks. Treatment for lightheadedness depends on the underlying cause. If dehydration is the culprit, increasing fluid intake, particularly water and electrolyte-rich drinks, can alleviate symptoms. For lightheadedness caused by low blood sugar, consuming a quick source of glucose, like fruit juice or a piece of candy, can provide relief. If standing up too quickly causes the sensation, taking care to rise slowly from sitting or lying positions can help prevent episodes. For those whose lightheadedness is medication-induced, adjusting the dosage or switching medications under a doctor's supervision may be necessary. In cases where an underlying medical condition is the cause, such as a heart problem or anemia, treating the condition itself is crucial. Managing anxiety through relaxation techniques, cognitive-behavioral therapy, or medication can also help if psychological factors are contributing. If lightheadedness is persistent, recurrent, or accompanied by other concerning symptoms like chest pain or shortness of breath, it is essential to seek medical evaluation to determine the cause and appropriate treatment.
