The doctor asked about his condition and measured his blood pressure, the result was 140/100mmHg. The doctor suggested: 1, rest, avoid overworking and staying up late, reduce socializing; 2, eat lightly; 3, measure blood pressure every day for the last 3 days. The doctor gave him a diagnosis of hypertension and had him undergo laboratory tests. Xiao Zhang’s self-symptoms improved through regular life regulation and diet regulation. Blood pressure also decreased, so he insisted on life regulation. In the following 3 months, his high pressure was always around 120mmHg, while his low pressure was always higher than 90mmHg. Finally, the doctor diagnosed him with hypertension and recommended him to further lower his blood pressure. Zhang thought: I’m young, if I start taking medication now, how troublesome, but do not take medication blood pressure is still high, and damage to health, torn ah! For this situation, the doctor advised Xiao Zhang: continue life regulation and diet control, while increasing aerobic exercise walking 12,000 steps a day to reduce weight. At the doctor’s suggestion, Zhang wore a pedometer to supervise himself every day to walk as much as possible, and began to make further changes. Many people don’t understand, just having high low pressure is considered high blood pressure? Of course it is. In fact, in reality, there are many hypertensive patients like Xiao Zhang who only have elevated low pressure. Most of them are young and vigorous age, when hypertension is found only low pressure elevation, high pressure is normal or slightly elevated. As they grow older and the hardening and elasticity of the large arteries disappear, they show a significant increase in high pressure, while the low pressure is normal or significantly lower, and the pulse pressure is very large. Therefore, high low pressure is a manifestation of hypertension and must be taken seriously.
