Regular visits with your doctor are also key to controlling your blood pressure. If your blood pressure is well-controlled, check with your doctor about how often you need to check it. Your doctor may suggest checking it daily or less often. If you're making any changes in your medications or other treatments, your doctor may recommend you check your blood pressure starting two weeks after treatment changes and a week before your next appointment.
Stroke. A stroke occurs when part of your brain is deprived of oxygen and nutrients, causing brain cells to die. Uncontrolled high blood pressure can lead to stroke by damaging and weakening your brain's blood vessels, causing them to narrow, rupture or leak. High blood pressure can also cause blood clots to form in the arteries leading to your brain, blocking blood flow and potentially causing a stroke.
A later study, published in the Journal of Hypertension, found similar results. Researchers analyzed data from 4,680 participants aged 40 to 59 years from 17 different areas in Japan, China, the United Kingdom, and the United States. They looked at blood pressure, cholesterol levels, and diet over the previous 24 hours. The results showed that cholesterol was directly related to blood pressure for all participants.
Most doctors do not make a final diagnosis of high blood pressure until they measure your blood pressure several times (at least 2 blood pressure readings on 3 different days). Some doctors ask their patients to wear a portable machine that measures their blood pressure over the course of several days. This machine may help the doctor find out whether a patient has true high blood pressure or what is known as “white-coat hypertension.” White-coat hypertension is a condition in which a patient’s blood pressure rises during a visit to a doctor when anxiety and stress probably play a role.
Lifelong control of hypertension will minimize the risk of developing heart attack, stroke, kidney failure, blindness, and a variety of other illnesses. Unlike other illnesses in which medications are taken for only a short period of time, high blood pressure medication is usually expected to be taken for the rest of the individual's life. It is uncommon, but not rare, that significant lifestyle changes can lower blood pressure readings to normal.

The brain requires unobstructed blood flow to nourish its many functions. Very high, sustained blood pressure will eventually cause blood vessels to weaken. Over time these weaken vessels can break, and blood will leak into the brain. The area of the brain that is being fed by these broken vessels start to die, and this will cause a stroke. Additionally, if a blot clot blocks a narrowed artery, blood ceases to flow and a stroke will occur.

Kidney failure. High blood pressure is one of the most common causes of kidney failure. That's because it can damage both the large arteries leading to your kidneys and the tiny blood vessels (glomeruli) within the kidneys. Damage to either makes it so your kidneys can't effectively filter waste from your blood. As a result, dangerous levels of fluid and waste can accumulate. You might ultimately require dialysis or kidney transplantation.
Diabetes can upset the balance between HDL and LDL cholesterol levels. People with diabetes tend to have LDL particles that stick to arteries and damage blood vessel walls more easily. Glucose (a type of sugar) attaches to lipoproteins (a cholesterol-protein package that enables cholesterol to travel through blood). Sugarcoated LDL remains in the bloodstream longer and may lead to the formation of plaque. People with diabetes tend to have low HDL and high triglyceride (another kind of blood fat) levels. Both of these boost the risk of heart and artery disease.
Blood pressure is more than just a number. Managing hypertension can reduce your risk of heart attack, stroke, and early death. If you’re committed to making positive lifestyle changes and managing your blood pressure, you can reduce or even eliminate your need for blood pressure medication. Lower your blood pressure and take control of your health.
