Hi, Lightheadedness has many causes, including:
- Allergies.
- Illnesses such as the flu or colds. Home treatment of your flu and cold symptoms usually will relieve lightheadedness.
- Vomiting, diarrhea, fevers, and other illnesses that cause dehydration.
- Very deep or rapid breathing (hyperventilation).
- Anxiety and stress.
- The use of tobacco, alcohol.
Anxiety and stress is the cause of being light-headed most of the time.
