Causes of Lightheadedness and Dizziness

Several factors can lead to feelings of lightheadedness and dizziness, including stress or anxiety. Additionally, low blood sugar levels (hypoglycemia) are common, particularly in individuals with diabetes. Another cause can be a sudden drop in blood pressure when changing positions quickly, known as postural hypotension. Lastly, dehydration or heat exhaustion can also contribute to these sensations.
