What usually causes this
Anaemia
Very common, especially in women. Causes lightheadedness and breathlessness on exertion.
Low blood pressure on standing
Common in heat and with dehydration, and with some medications.
Low blood sugar
Particularly in people on diabetes medication, or after long gaps without food.
Inner ear problems
True spinning sensation, often with nausea, usually settles with treatment.
Heart rhythm problems
Less common but important — dizziness with palpitations needs assessment.
