Lightheadedness
A feeling of faintness and lightheadedness could indicate many things. It could be a sign of dehydration, anemia, a panic attack, or low blood sugar. In some cases, it may be brought about by some medication treatments. Lightheadedness may also be a symptom of a stroke or a heart attack in the worst-case scenario. It could also be a manifestation of a blood clot.
Lightheadedness or feeling nauseous, sweaty, and unsteady usually occurs when the brain lacks enough blood. It may typically happen when people abruptly change from sitting down to standing up. But while it may happen without life-threatening indications, people should give a frequent feeling of lightheadedness suitable medical attention.
Lightheadedness becomes a medical emergency when it indicates loss of a lot of blood or a blood clot in the arm, especially when the patient has trouble speaking or feels heavy pressure on the chest.
