Higher blood pressure at night is possible according to the doctor’s instructions to add medication, but do not add medication without authorization. Higher blood pressure at night may be caused by a change in the circadian rhythm of blood pressure fluctuations, by a poor medication regimen that does not last through the night, or by poor lifestyle habits at night, such as smoking, drinking alcohol, drinking tea, and engaging in excitatory activities. People with high blood pressure need to keep it under strict control and keep it stable every day to avoid damage to the cardiovascular system. Therefore, if your blood pressure increases at night, you should go to the hospital, and according to the doctor’s inquiry and examination to find out the cause, and then add medicine and change the dosage of medicine to maintain the stability of blood pressure, and at the same time, strictly prohibit unauthorized addition of medicine to avoid serious consequences.
