An elevated blood pressure is clearly identified when both systolic blood pressure ≥ 140 and/or diastolic blood pressure ≥ 90 mmHg are measured under the premise of correct blood pressure measurement. A sudden increase in blood pressure may be a physiological change or there may be a pathological trigger, and the appropriate interventions should be taken for the specific situation. When elevated blood pressure is detected, the following steps can be referred to: 1. Immediate treatment methods: Anxiety and fear can contribute to a further increase in blood pressure, and it is recommended to remain calm and rest in bed. If the rise in blood pressure is physiological due to emotional excitement or after exercise, it can return to normal by getting rid of the trigger. Patients who find high blood pressure for the first time should not take other people’s antihypertensive drugs on their own, but should go to the hospital as soon as possible to clarify the diagnosis and follow the doctor’s instructions; if patients who have been diagnosed with hypertension find a sudden rise in blood pressure, they should promptly take the antihypertensive drugs prescribed by the doctor during the previous visit, and improve their lifestyle to control the causes of the rise in blood pressure. 2, control the triggers: sudden increase in blood pressure may be caused by not paying attention to control the triggers that raise blood pressure, therefore, you need to avoid staying up late, quit smoking, quit drinking, prohibit overeating or excessive dieting, control blood sugar, maintain emotional stability, avoid irritability, avoid heat stroke, dehydration and other conditions. Because these conditions can induce rapid changes in blood pressure within a short period of time. 3, follow the doctor’s instructions reasonable use of drugs: blood pressure is normal to stop the drug, blood pressure rises and then take the drug, this kind of irregular medication, will lead to a large rise and fall in blood pressure. Anti-hypertensive drugs need to be taken continuously and regularly in order to lower blood pressure smoothly. Most antihypertensive drugs should be taken on an empty stomach, some slow-release, controlled-release dosage form of drugs, can not be broken or chewed to take. 4, secondary hypertension: secondary hypertension can occur in normal people who do not have hypertension, but also in patients who have suffered from primary hypertension. Clinically manifested as a paroxysmal increase in blood pressure or stable blood pressure after taking medication, or sustained elevation, often accompanied by other uncomfortable symptoms, the need for timely consultation. In simple secondary hypertension, after eliminating the primary disease, most patients can return to normal blood pressure, without the need to take antihypertensive drugs. 5, home blood pressure monitoring: most hypertensive patients need long-term or lifelong medication, but the timing of medication, the amount of medication, how the combination of drugs, is not fixed. Blood pressure fluctuates throughout the day, and the pattern of blood pressure changes varies from day to day, and with the change of seasons blood pressure will change accordingly, so standardized home self-measurement of blood pressure is an important part of blood pressure management. Sudden increases in blood pressure must be treated promptly to avoid cardiovascular and cerebrovascular adverse events and to prolong life expectancy and improve quality of life. When you notice an increase in blood pressure, please follow the individualized principle and choose a treatment plan that suits you under the guidance of your doctor.
