Sweating and dizziness while working are mainly considered for the following reasons: First, if a patient with previous hypertension has sweating and dizziness while working, get his blood pressure measured. Some patients have elevated blood pressure during activity, which may manifest as dizziness, sweating, nausea, and vomiting; second, if sweating and dizziness occur while working, ask the patient if he or she usually has low blood pressure. There are some patients who have insufficient amount of fluid due to a lot of sweating while working, and they are prone to hypotension, which can be manifested as dizziness. The patient may need to do electrocardiogram plus cardiac ultrasound and cardiac enzymology.
