Since high blood pressure may not cause any symptoms, it can be distressing to visit your doctor and obtain a high blood pressure reading. Triggers for high blood pressure may include heart disease, high cholesterol, excessive salt consumption, and smoking. Individuals at risk for high blood pressure include those who are advancing in age, overweight, or have a family history of the condition. In addition to the long-term effects that genetics, smoking, or obesity can have on the heart, there are more temporary conditions that can cause acute increases in your blood pressure. 10. The Need to PeeYou may be surprised to learn that your blood pressure increases when you need to urinate. One study noted a rise in blood pressure in middle-aged women who had gone at least three hours without urinating. Therefore, when visiting your doctor for a checkup, it may be wise to empty your bladder before having your vital signs checked. Additionally, a study in the Journal of Hypertension found that frequently getting up in the night to urinate was linked to a rise in blood pressure. 9. Consuming Added SugarYou are likely well aware of the risk of high blood pressure due to excessive dietary salt. However, the consumption of excess sugar may also trigger a rise in blood pressure. High fructose corn syrup, in particular, may contribute to an increased risk of high blood pressure. A study in the Journal of the American Society of Nephrology linked consumption of high fructose corn syrup to elevated blood pressure measurements in healthy adults. Ditch the processed foods with their added sugars and stick to the sweetness of heart-healthy fruits instead.
