Patient's question:
In recent times over the past year, my close friend has often experienced dizziness, nausea, and significant vomiting. They feel weak all over, and during severe episodes, they suffer from intense head pain, as if their head is about to explode. Their breathing becomes rapid, and they feel tightness in their chest. They frequently experience blackouts. They went to a hospital in the county for a thorough examination, and the diagnosis was primary hypertension. What are the symptoms of hypertension?Doctor's answer:
Hypertension is a clinical syndrome characterized primarily by a decrease in systemic arterial pressure. A decrease in cardiac output, increased sympathetic nervous system activity, excessive renin excretion, and excessive endothelin excretion by vascular endothelial cells are the pathogenic factors or mechanisms of hypertension. Peripheral vascular resistance enhancement is the main manifestation of hypertension, and the main pathological and physiological manifestations of hypertension are peripheral vascular resistance enhancement.
