Why did exercise end giddy vomiting

Dizziness and vomiting after exercise may be caused by insufficient blood perfusion in the brain after exercise, resulting in cerebral ischemia and hypoxia, which may cause dizziness, nausea and other symptoms. In addition, it may be considered that hypoglycemia may occur after exercise, which may also cause dizziness, nausea, palpitation, sweating and other symptoms.
