Imagine a garden hose hooked up to a spigot. When the hose is flexible and there are no kinks in it, you can turn on the water full blast and it will flow easily through the hose. But if there’s a kink in the hose, the water doesn’t flow as well beyond the kink. And the pressure inside the hose builds up behind the kink. Or imagine there is gunk inside the hose blocking the path of the water. Your arteries are a lot like that garden hose.

Treatment for high blood pressure is decided based on current medical conditions. In some cases, intravenous therapy is started on emergency basis while further tests are conducted to identify the pathology in other cases. Based on the outcomes, a regimen is provided by the doctor in order to control the blood pressure. If high blood pressure results from different pathologies, then multiple therapies may also be conducted. In more severe cases such as advanced kidney damage or tumors, surgical intervention may also have to be carried out."
The JAMA study was an extensive chart review of over 38,000 patients at low risk for heart disease who had stage two hypertension (blood pressure between 149/90 and 159/99) and were treated with blood pressure medications. Over an average follow-up time of almost six years, they found no reduction in the risk of cardiovascular disease events or risk of death with medication use. They did, however, find an increased risk for low blood pressure, fainting, and acute kidney injury among those treated with medications.
An exception to this is those with very high blood pressure readings especially when there is poor organ function.[79] Initial assessment of the hypertensive people should include a complete history and physical examination. With the availability of 24-hour ambulatory blood pressure monitors and home blood pressure machines, the importance of not wrongly diagnosing those who have white coat hypertension has led to a change in protocols. In the United Kingdom, current best practice is to follow up a single raised clinic reading with ambulatory measurement, or less ideally with home blood pressure monitoring over the course of 7 days.[79] The United States Preventive Services Task Force also recommends getting measurements outside of the healthcare environment.[80] Pseudohypertension in the elderly or noncompressibility artery syndrome may also require consideration. This condition is believed to be due to calcification of the arteries resulting in abnormally high blood pressure readings with a blood pressure cuff while intra arterial measurements of blood pressure are normal.[81] Orthostatic hypertension is when blood pressure increases upon standing.[82]
Kiwis are another fruit that positively impacts blood pressure. Some researchers studied how the fruit fares compared to apples. They found that eating three kiwis a day over eight weeks reduced blood pressure in people with slightly high blood pressure more so than eating one apple per day during the same time. A daily serving of kiwi was also found to reduce blood pressure in people with only mildly elevated levels. Kiwis are also an excellent source of vitamin C which can also also improve blood pressure. 
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.
In the study, Naci's team analyzed data from 197 clinical trials that assessed the effects of structured workouts on lowering systolic blood pressure, the top number in a reading. The investigators also looked at data from 194 trials that examined the impact of prescription drugs on blood pressure. In total, the studies included nearly 40,000 people.
Health care providers measure blood pressure with a sphygmomanometer (sfig-mo-muh-NAH-muh-ter), which has a cuff that's wrapped around the upper arm and pumped up to create pressure. When the cuff is inflated, it squeezes a large artery in the arm, stopping the blood flow for a moment. Blood pressure is measured as air is gradually let out of the cuff, which allows blood to flow through the artery again.

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.
Essential hypertension is also greatly influenced by diet and lifestyle. The link between salt and high blood pressure is especially compelling. People living on the northern islands of Japan eat more salt per capita than anyone else in the world and have the highest incidence of essential hypertension. By contrast, people who add no salt to their food show virtually no traces of essential hypertension.
In addition to medications your doctor may prescribe, there are several lifestyle changes you can make to help to lower your blood pressure. These include things like eating a healthy diet, maintaining a regular exercise routine, quitting smoking and limiting your alcohol intake. Here are five more blood pressure-reducing techniques that don’t require a prescription:

Johns Hopkins researchers have identified the genes responsible for aortic ballooning and the sequence of events leading to aortic aneurysms. Dr. Hal Dietz currently conducts clinical trials of therapies for people with inherited aortic aneurysms to improve health and quality of life for these patients.Learn more about Dr. Deitz and his aortic ballooning therapies.
The cuff is placed around the upper arm and inflated with an air pump to a pressure that blocks the flow of blood in the main artery that travels through the arm. The arm is held at the side of the body at the level of the heart, and the pressure of the cuff is gradually released. As the pressure decreases, a health practitioner listens with a stethoscope over the artery at the front of the elbow or an electronic machine senses the pulsation. The pressure at which the practitioner (or machine) first hears a pulsation from the artery is the systolic pressure (the top number). As the cuff pressure decreases further, the pressure at which the pulsation finally stops is the diastolic pressure (the bottom number).

Blood tests may be done to assess risk factors for heart disease and stroke as well as looking for complications of hypertension. These include complete blood count (CBC), electrolytes, BUN (blood urea nitrogen), and creatinine and GFR (glomerular filtration rate) to measure kidney function. A fasting lipid profile will measure cholesterol and triglyceride levels in the blood. If appropriate, blood tests may be considered to look for an underlying cause of high blood pressure (secondary hypertension)including abnormal thyroid or adrenal gland function.
Blood pressure control is a lifelong challenge. Hypertension can progress through the years, and treatments that worked earlier in life may need to be adjusted over time. Blood pressure control may involve gradually making lifestyle changes like diet, weight loss, exercise, and possibly taking medicine if necessary. In some situations, medications may be recommended immediately. As with many diseases, you and your doctor should work together to find the treatment plan that works for you.
