Sudden increase in blood pressure, dizziness, vomiting and then normal may be due to stress, emotional over-excitement and other physiological factors, but also may be due to pheochromocytoma and other pathological factors.
1. Physiological factors: when the patient is suddenly nervous and over-excited, the sympathetic nerves will be over-excited, which will lead to a transient increase in blood pressure, dizziness and vomiting. Patients can usually return to normal after calming down.
2. Pheochromocytoma: Pheochromocytoma can intermittently release a large amount of catecholamines (such as epinephrine, etc.), which will cause vasoconstriction and increase cardiac output, thus leading to paroxysmal hypertension, which will cause dizziness and vomiting, and then return to normal.
After eliminating physiological factors, patients who still experience sudden increase in blood pressure, dizziness and vomiting and then normalization, should go to regular hospitals in a timely manner, under the guidance of a professional doctor for standardized treatment, so as to avoid delays in the condition.
