Patients with hypertension who specifically have morning hypertension have a higher risk of stroke, compared with other hypertensive patients without morning hypertension Figure 2. High blood pressure can cause a stroke, which is a sudden loss of brain function due to a lack of blood supply to the brain. Two types of stroke exist?
A stroke caused by a blood clot is called an ischemic stroke. Hemorrhagic strokes occur when a blood vessel ruptures in the brain. Morning hypertension also can increase your risk of other heart and blood vessel problems. It has been associated with changes in your heart's rhythm and size, which can lead to a heart attack or heart failure. Be sure to contact your doctor immediately if you experience symptoms such as severe headache, chest pain, and numbness or tingling in your face or arms.
Doctors recommend that patients monitor their blood pressure at home to help determine their risk of morning hypertension by using a home blood pressure monitor that has been clinically proven to be accurate. You can purchase a home blood pressure monitor without a prescription at your local pharmacy.
Several types of monitors are available, including automatic and manual models. The only home blood pressure monitor currently on the market cleared by the FDA to help determine a patient's risk of morning hypertension is manufactured by Omron Healthcare Model HEM In the study, researchers looked at data from people in Japan and found that, when measured in the morning, higher blood pressure was related to an increased risk of stroke.
When measured in the evening, however, higher blood pressure was not as closely related to people's stroke risk. Blood pressure has a tendency to surge in the morning, and this surge is greater in Asian populations than in people in Western countries, said Dr. Satoshi Hoshide, an associate professor of cardiovascular medicine at Jichi Medical University in Japan and the lead author of the study. Because of this, the morning blood pressure measurement is important, especially in Asian populations, Hoshide told Live Science today Nov.

The top number denotes systolic blood pressure, which is the pressure when the heart contracts. The bottom number shows diastolic blood pressure, which is a measure of the pressure when the heart relaxes. A blood pressure monitor uses a unit of measurement called millimeters of mercury mm Hg to measure the pressure inside the blood vessels.
Blood pressure rises and falls throughout the day and night. It then increases around the time of wakening. In some people, this increase may be significant, resulting in morning hypertension. People who have an abnormal blood pressure pattern may be at risk of complications, such as heart attack and stroke.
As a review notes, the onset of stroke and other serious cardiac events peaks in the first 4—6 hours after waking. Regular use of a home blood pressure monitor can help people better understand their blood pressure fluctuations. It can also allow people to identify episodes of morning hypertension. These monitors are more reliable than monitors that attach to the finger or wrist. High blood pressure typically does not cause symptoms, even when levels are dangerously high.
Certain symptoms are more common in people with hypertension. However, they do not necessarily occur as a direct result of hypertension. These symptoms include:. Depending on what these readings show, a doctor may recommend a 24 hour blood pressure monitoring test.
This test involves wearing a device that takes regular blood pressure readings throughout the day and night. If necessary, they may order additional tests to confirm or rule out a diagnosis.
