Hi thanks for asking question. Hypertension can lead to headache, nausea , sweating etc.symptoms. Hypertension not directly lead to dizziness. Dizziness might be from other causes like hypoglycemia , sleep deprivation , dehydration , labyrinthitis , antihypertensive medication enalapril etc. You have not mentioned your blood pressure. In mild stage of hypertension try to control it with life style measures like low salt diet, regular exercise.Avoid alcohol and stop smoking. Green leafy vegetables helpful.Drink more water. If your blood pressure moderately high then amlodipine or losartan like drug can be started. Finally if you have difficulty in walking, slurred speech etc.like neurological symptoms then stroke should be though that can lead to dizziness. Wish you good health.
