Patients with primary hypertension can eat a little sugar, but not too much. Patients with diabetes, obesity and other diseases should eat as little or no sugar as possible. In recent years, the number of people suffering from hypertension has been increasing, and there are many causes of hypertension, most of which are caused by poor diet and lifestyle habits. Studies have shown that eating sugary drinks more than three times a day increases the risk of hypertension by 87%. Excess sugar may be converted into fat in the body, accelerating the production of atherosclerosis, which can eventually increase the resistance of peripheral blood vessels and lead to an increase in blood pressure. Eating too much sugar at one time may cause an increase in blood sugar and increase insulin secretion in the body, which reflexively makes the body’s heart beat faster and blood vessels constrict, causing an increase in blood pressure. Long-term excessive sugar intake may also lead to obesity in patients with hypertension, increasing the risk of coronary heart disease and other cardiovascular diseases.
