Whether the symptoms of hypertension at the age of forty are terrible or not, it mainly depends on the control situation and complications; simple hypertension, controlled and stabilized by medication is not terrible; unstable hypertension, with bad effect after medication or accompanied by obvious complications (atherosclerosis, etc.), belongs to a relatively terrible situation. 1. Simple hypertension is not scary if the blood pressure is controlled stably through standardized application of medication and there is no complication in the body, which will not have a particularly great impact on the body. 2. Once malignant hypertension or unstable hypertension occurs, accompanied by atherosclerosis, aneurysm and other conditions, it may cause bleeding, which is a relatively scary situation, and should be regulated under the guidance of clinicians. If you have high blood pressure with obvious symptoms of headache and dizziness, you need to consult a doctor in time and have standardized treatment under the guidance of a clinician.
