Yes, blood spots in the eyes, or subconjunctival hemorrhage, are more common in people with diabetes or high blood pressure, but neither condition causes the blood spots. Floaters in the eyes are not related to high blood pressure. However, an ophthalmologist may be able to detect damage to the optic nerve caused by untreated HBP.
Facial flushing occurs when blood vessels in the face dilate. The red, burning face can occur unpredictably or in response to certain triggers such as sun exposure, cold weather, spicy foods, wind, hot drinks and skin-care products. Facial flushing can also occur with emotional stress, exposure to heat or hot water, alcohol consumption and exercise, all of which can raise blood pressure temporarily. While facial flushing may occur while your blood pressure is higher than usual, HBP is not the cause of facial flushing.
Although it is not caused by HBP, dizziness can be a side effect of some high blood pressure medications. Nonetheless, dizziness should not be ignored, especially if you notice a sudden onset. Sudden dizziness, loss of balance or coordination and trouble walking are all warning signs of a stroke. HBP is one of the leading risk factors for stroke.
As mentioned above, only when blood pressure readings soar to dangerously high levels (systolic of 180 or higher OR diastolic of 110 or higher) may obvious symptoms occur. Blood pressure this high is known as hypertensive crisis, and emergency medical treatment is needed.
