What are the reasons of giddyness?

Giddiness, often described as a feeling of lightheadedness or dizziness, can be caused by various factors. Common reasons include dehydration, low blood sugar, or sudden changes in position that affect blood flow. It can also result from inner ear issues, anxiety, or medication side effects. In some cases, giddiness may indicate a more serious underlying condition, so it's important to consult a healthcare professional if it persists.
