High blood pressure can drink cola in moderation, but not too much. However, if combined with diabetes, it is not allowed to drink cola. At present, China’s blood pressure standards are: normal: systolic blood pressure <120mmHg, diastolic blood pressure <80mmHg; high normal: systolic blood pressure 120～139mmHg and/or diastolic blood pressure 80～89mmHg; hypertension: systolic blood pressure ≥140mmHg and/or diastolic blood pressure ≥90mmHg, which is applicable to adults over 18 years old. Hypertensive patients can drink cola in moderation, which generally does not have much effect on blood pressure control. However, the caffeine contained in cola may cause excitation of the nervous system, leading to an increase in blood pressure, so it is not recommended to drink large amounts. In addition, cola contains a lot of sugar, so if a hypertensive patient has diabetes, he or she should not drink cola, as it will lead to an increase in blood sugar, which may also cause an increase in blood pressure. Patients with high blood pressure are advised to maintain a low-salt and low-fat diet, lose weight, stop smoking and limit alcohol consumption, reduce mental stress, maintain a balanced mind, and take antihypertensive medication regularly as prescribed by a doctor if necessary. If you feel sick, consult a doctor in time and standardize the treatment under the doctor's guidance.
