For a normal reading, your blood pressure needs to show a top number (systolic pressure) that’s between 90 and less than 120 and a bottom number (diastolic pressure) that’s between 60 and less than 80. The American Heart Association (AHA) considers blood pressure to be within the normal range when both your systolic and diastolic numbers are in these ranges.
Instead of an arbitrary goal to “lose weight,” talk with your doctor about a healthy weight for you. The Centers for Disease Control and Prevention (CDC) recommends a weight loss goal of one to two pounds a week. That means starting off eating 500 calories less per day than what you normally eat. Then decide on what physical activity you can start in order to reach that goal. If exercising five nights a week is too hard to work into your schedule, aim for one more night than what you’re doing right now. When that fits comfortably into your schedule, add another night.
Certain groups of people—the elderly, African Americans, and those with a family history of high blood pressure—are more likely than others to have blood pressure that's particularly salt-sensitive. But because there's no way to tell whether any one individual is at risk, everyone should consume less sodium, says Eva Obarzanek, PhD, a research nutritionist at the National Heart, Lung, and Blood Institute.

With age, comes an increased risk for systolic hypertension which can be aggravated by severe atherosclerosis. According to one study, the diuretic chlorthalidone (Hygroton) had significant benefit in elderly patients with systolic hypertension. Along with a diuretic, some calcium channel blockers, ACE inhibitors and angiotensin II receptor blockers may also be good choices. However, beta blockers may not be as effective for hypertension in those over 60; though they may be good choices if co-existing heart disease is present. It also may be preferable in elderly patients to give two high blood pressure medications at a low dose versus one at a higher dose.
If you’re feeling overwhelmed about how to make changes to your diet or if you’re trying to lose weight, you may want to consider working with a registered dietitian-nutritionist (RDN). Some people work with an RDN if they have a health condition like type 2 diabetes. In fact, high blood pressure is a risk factor for type 2 diabetes. This is partly because they share similar modifiable risk factors, like being overweight or obese, following an unhealthy diet, and having a lack of physical activity.
When discussing blood pressure issues, the healthcare professional may ask questions about past medical history, family history, and medication use, including prescriptions, over-the-counter medications, herbal remedies, and food additives. Other questions may include lifestyle habits, including activity levels, smoking, alcohol consumption, and illegal drug use.
These drugs block the effects of angiotensin, a chemical that causes the arteries to become narrow. Angiotensin needs a receptor- like a chemical "slot" to fit into or bind with- in order to constrict the blood vessel. ARBs block the receptors so the angiotensin fails to constrict the blood vessel. This means blood vessels stay open and blood pressure is reduced.
For most people, the first-choice medication for high blood pressure is a thiazide diuretic. For other people, a diuretic alone is not enough to control blood pressure. In these cases, a diuretic may be combined with a beta-blocker, ACE inhibitor, angiotensin II receptor blocker, or calcium channel blocker. Adding a second medication may lower your blood pressure more quickly than using a diuretic alone. Also, it allows you to take less of each medication, which may reduce side effects.

In “guessing” on the best initial single drug to try, most experts now recommend beginning either with either a thiazide diuretic (usually chlorthalidone or hydrochlorothiazide), a long-acting calcium blocker, or an ACE inhibitor. ARBs are generally thought of as substitutes for ACE inhibitors, and generally, are used only when ACE inhibitors are poorly tolerated.

Healthcare professionals use a stethoscope and a manual sphygmomanometer to measure your blood pressure. Typically they take the reading above your elbow. The sphygmomanometer has a bladder, cuff, bulb, and a gauge. When the bulb is pumped it inflates the bladder inside the cuff, which is wrapped around your arm. This inflation will stop the blood flow in your arteries. The stethoscope is used to listen for sound of the heartbeat, and no sound indicates that there is no flow. As the pressure is released from the bladder, you will hear the sound of the blood flowing again. That point becomes systolic reading. The diastolic reading is when you hear no sound again, which means that the blood flow is back to normal.

Many kids and teens with high blood pressure have an unhealthy lifestyle — a bad diet, excess weight, stress, and too little physical activity. So the health care provider might recommend weight loss, exercise, reduced screen time (time spent watching TV, or using a computer or mobile devices), dietary changes, and even relaxation techniques. Teens with hypertension should not smoke because it can make the long-term associated heart problems worse.
Blood pressure fluctuates throughout the day, so measuring it in the morning might yield a different number than, say, the afternoon. Conditions like stress and lack of sleep can also fluctuate blood pressure. Visiting your doctor might feel nerve-wracking, which can elevate your blood pressure and create a condition called white coat hypertension.
Blood spots in the eyes : Blood spots in the eyes (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 also not related to high blood pressure. However, an eye doctor (ophthalmologist) may be able to detect damage to the optic nerve caused by untreated high blood pressure.   

Blood pressure is measured both when the heart is actually beating (systolic pressure – the first measurement) and between beats (the resting rate, or diastolic pressure – the second measurement). It is given as two figures, eg 120/80. A device called a sphygmomanometer is used. An inflatable cuff is wrapped around your upper arm. When inflated the cuff stops the blood flow in the main blood vessel in your arm. The nurse then watches a gauge in the sphygmomanometer and listens through a stethoscope as the air in the cuff is released. When the first sound of the heartbeat is heard, the systolic pressure is recorded. When the sound disappears, the diastolic pressure is recorded. Sometimes a computerised blood pressure machine is used to take the readings automatically.
About This Image: Person receiving a blood pressure test. Medical research shows that as we age blood pressure rises slightly to accommodate an increased demand of oxygen and nutrients. It is completely natural for the first number (systolic) to be 100 plus our age. A recent study by a group of UCLA researchers came very close to corroborating Dr. Piette's guide for blood pressure of 100 plus your age for men, subtracting 10 for women, and this is after this rule had been in use for five or more decades. Are we now being taught that Dr. Piette's guide for blood pressure is wrong merely for drug company profit?
An important part of a high blood pressure treatment plan is to stick to a healthy diet, including limiting sodium intake. The 2015-2020 Dietary Guidelines for Americans recommend consuming less than 2,300 milligrams (mg) of sodium per day (2). People with high blood pressure may need to restrict sodium intake even more. The American Heart Association (AHA) recommends an ideal limit of no more than 1,500 mg per day for adults with hypertension. (3)
Hypertension is a common diagnosis in medical practice and is usually considered to bear a serious connotation. Arterial hypertension has been described as the most common and important of all types of heart diseases.1 Yet the levels which constitute abnormally high blood pressure at various ages have not been accurately determined. The various figures now in use—140, 150 or 160 mm. of mercury systolic and 90 to 100 mm. of mercury diastolic—are arbitrary, particularly when age is concerned. The observation that many persons with high blood pressure live to old age suggests that undue significance is frequently attached to the degree of hypertension.2
7. Visit your chiropractor. A special chiropractic adjustment could significantly lower high blood pressure, a placebo-controlled study suggests. “This procedure has the effect of not one, but two blood–pressure medications given in combination,” study leader George Bakris, MD, told WebMD. Your chiropractor can create an effective protocol that helps normalize blood pressure without medication or other invasive procedures.
Your total blood pressure reading is determined by measuring your systolic and diastolic blood pressures. Systolic blood pressure, the top number, measures the force your heart exerts on the walls of your arteries each time it beats. Diastolic blood pressure, the bottom number, measures the force your heart exerts on the walls of your arteries in between beats.
