Globally, black adults have among the highest rates of hypertension, with an increasing prevalence. Although white adults also have an increasing incidence of high BP, they develop this condition later in life than black adults and have much lower average BPs. In fact, compared to hypertensive white persons, hypertensive black individuals have a 1.3-fold higher rate of nonfatal stroke, a 1.8-fold higher rate of fatal stroke, a 1.5-fold higher mortality rate due to heart disease, and a 4.2-fold higher rate of end-stage renal disease (ESRD).

Potassium – as part of the electrolyte panel, which also includes sodium, chloride, and carbon dioxide (CO2); to evaluate and monitor the balance of the body's electrolytes. For example, low potassium can be seen in Cushing syndrome and Conn syndrome, two causes of secondary hypertension. Some high blood pressure medications can upset electrolyte balance by causing excessive loss of potassium or potassium retention.

Insulin resistance also may increase your risk for metabolic syndrome. Insulin resistance is a condition in which the body can’t use its insulin properly. Insulin is a hormone that helps move blood sugar into cells where it’s used for energy. Insulin resistance can lead to high blood sugar levels, and it’s closely linked to overweight and obesity. Genetics (ethnicity and family history) and older age are other factors that may play a role in causing metabolic syndrome.
Exposure to certain viral infections (mumps and Coxsackie viruses) or other environmental toxins may serve to trigger abnormal antibody responses that cause damage to the pancreas cells where insulin is made. Some of the antibodies seen in type 1 diabetes include anti-islet cell antibodies, anti-insulin antibodies and anti-glutamic decarboxylase antibodies. These antibodies can be detected in the majority of patients, and may help determine which individuals are at risk for developing type 1 diabetes.

Resistant hypertension is defined as high blood pressure that remains above a target level, in spite of being prescribed three or more antihypertensive drugs simultaneously with different mechanisms of action.[131] Failing to take the prescribed drugs, is an important cause of resistant hypertension.[132] Resistant hypertension may also result from chronically high activity of the autonomic nervous system, an effect known as "neurogenic hypertension".[133] Electrical therapies that stimulate the baroreflex are being studied as an option for lowering blood pressure in people in this situation.[134]
Type 2 DM is characterized by insulin resistance, which may be combined with relatively reduced insulin secretion.[11] The defective responsiveness of body tissues to insulin is believed to involve the insulin receptor. However, the specific defects are not known. Diabetes mellitus cases due to a known defect are classified separately. Type 2 DM is the most common type of diabetes mellitus.[2]

So far, none of the hypotheses accounting for virus-induced beta cell autoimmunity has been supported by stringent evidence in humans, and the involvement of several mechanisms rather than just one is also plausible.
Type 1 diabetes is partly inherited, with multiple genes, including certain HLA genotypes, known to influence the risk of diabetes. In genetically susceptible people, the onset of diabetes can be triggered by one or more environmental factors,[41] such as a viral infection or diet. Several viruses have been implicated, but to date there is no stringent evidence to support this hypothesis in humans.[41][42] Among dietary factors, data suggest that gliadin (a protein present in gluten) may play a role in the development of type 1 diabetes, but the mechanism is not fully understood.[43][44]
Hypertension is diagnosed on the basis of a persistently high resting blood pressure. The American Heart Association recommends at least three resting measurements on at least two separate health care visits.[74] The UK National Institute for Health and Care Excellence recommends ambulatory blood pressure monitoring to confirm the diagnosis of hypertension if a clinic blood pressure is 140/90 mmHg or higher.[75]
Type 2 DM begins with insulin resistance, a condition in which cells fail to respond to insulin properly.[2] As the disease progresses, a lack of insulin may also develop.[12] This form was previously referred to as "non insulin-dependent diabetes mellitus" (NIDDM) or "adult-onset diabetes".[2] The most common cause is a combination of excessive body weight and insufficient exercise.[2]
With secondary hypertension, if the condition causing the high blood pressure can be resolved (e.g., by removing an adrenal tumor or stopping a medication) or controlled (e.g., by controlling diabetes or thyroid disease), then blood pressure levels may fall to normal or near normal levels. When a cure is not possible and control of the underlying condition consists of minimizing further damage, as may occur with kidney disease, then hypertension will be controlled with a combination of medications and the person will be monitored closely to help maintain organ function and address acute problems as they arise.

A 2015 review of several studies found that restoring blood vitamin D levels by using supplements (more than 1,000 IU per day) reduced blood pressure in hypertensive individuals when they had existing vitamin D deficiency.[167] The results also demonstrated a correlation of chronically low vitamin D levels with a higher chance of becoming hypertensive. Supplementation with vitamin D over 18 months in normotensive individuals with vitamin D deficiency did not significantly affect blood pressure.[167]

Lifestyle changes and medications can lower blood pressure and decrease the risk of health complications.[8] Lifestyle changes include weight loss, physical exercise, decreased salt intake, reducing alcohol intake, and a healthy diet.[5] If lifestyle changes are not sufficient then blood pressure medications are used.[8] Up to three medications can control blood pressure in 90% of people.[5] The treatment of moderately high arterial blood pressure (defined as >160/100 mmHg) with medications is associated with an improved life expectancy.[14] The effect of treatment of blood pressure between 130/80 mmHg and 160/100 mmHg is less clear, with some reviews finding benefit[7][15][16] and others finding unclear benefit.[17][18][19] High blood pressure affects between 16 and 37% of the population globally.[5] In 2010 hypertension was believed to have been a factor in 18% of all deaths (9.4 million globally).[9]
Usually, diastolic pressures will mirror systolic pressures, but as people age, the diastolic pressure tends to level out. Then, the form of hypertension that involves primarily the systolic pressure (called isolated systolic hypertension) becomes more common. In general, the greater the blood pressure for extended periods of time, the greater the potential for damage.

One hypothesis is that prehypertension results in oxidation of lipids such as arachidonic acid that leads to the formation of isoketals or isolevuglandins, which function as neoantigens, which are then presented to T cells, leading to T-cell activation and infiltration of critical organs (eg, kidney, vasculature). [16] This results in persistent or severe hypertension and end organ damage. Sympathetic nervous system activation and noradrenergic stimuli have also been shown to promote T-lymphocyte activation and infiltration and contribute to the pathophysiology of hypertension. [17, 18, 19]
You can take additional magnesium if you do not think you’re getting enough in the diet. Dr. Weil recommends magnesium citrate, chelate, or glycinate. Avoid magnesium oxide, which can be irritating, and take half the amount of magnesium as the calcium you take in supplemental form. If you do not take any supplemental calcium, watch out for taking large amounts of magnesium, which can cause diarrhea.
People who have metabolic syndrome typically have apple-shaped bodies, meaning they have larger waists and carry a lot of weight around their abdomens. It's thought that having a pear-shaped body — that is, carrying more of your weight around your hips and having a narrower waist — doesn't increase your risk of diabetes, heart disease and other complications of metabolic syndrome.
The good news is that if you suspect you might have metabolic damage there are real answers and solutions and even tests to tell you what is going wrong in your body.  For those looking to get answers on how to fix metabolism problems and metabolic damage we have created a FREE  3 part Metabolic Repair Video Course that walks you through all the steps.  From how to get the correct tests to a done for you comprehensive metabolism assessment we cover it all in the course.  The course will teach you:
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.
Once the diagnosis of hypertension has been made, healthcare providers should attempt to identify the underlying cause based on risk factors and other symptoms, if present. Secondary hypertension is more common in preadolescent children, with most cases caused by kidney disease. Primary or essential hypertension is more common in adolescents and has multiple risk factors, including obesity and a family history of hypertension.[83] Laboratory tests can also be performed to identify possible causes of secondary hypertension, and to determine whether hypertension has caused damage to the heart, eyes, and kidneys. Additional tests for diabetes and high cholesterol levels are usually performed because these conditions are additional risk factors for the development of heart disease and may require treatment.[6]

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
“Your doctor is probably not trained about the types of exercises and their related recommended intensities for improving specific parameters of this syndrome,” says Joey Gochnour, RDN, an exercise physiologist in Austin, Texas. Gochnour points out that even moderate aerobic exercise can improve cholesterol levels. He recommends exercising regularly, preferably at least 30 minutes a day, five days a week to help ward off metabolic syndrome.
Formal guidelines for measuring blood pressure state that it should be measured in a quiet, warm environment after you have been sitting restfully for at least five minutes. You should not have had coffee or used tobacco for at least 30 minutes. At least two blood pressure measurements should be taken under these conditions at least five minutes apart. This should be repeated until the measurements agree to within 5 mmHg.
Weight loss surgery in those with obesity and type two diabetes is often an effective measure.[14] Many are able to maintain normal blood sugar levels with little or no medications following surgery[95] and long-term mortality is decreased.[96] There is, however, a short-term mortality risk of less than 1% from the surgery.[97] The body mass index cutoffs for when surgery is appropriate are not yet clear.[96] It is recommended that this option be considered in those who are unable to get both their weight and blood sugar under control.[98]
Hypertension, the medical term for high blood pressure, is known as "the silent killer." More than 80 million Americans (33%) have high blood pressure, and as many as 16 million of them do not even know they have the condition. If left untreated, high blood pressure greatly increases your risk for heart attack and stroke. Hypertension is projected to increase about 8 percent between 2013 and 2030.
Here’s how it works: Each time you hit the gym, you work your whole body with circuits or pairs of multijoint, free-weight exercises that put the body through a full range of basic functional movements such as squatting, deadlifting, lunging, pulling, pushing and twisting. Because you exercise your entire body every workout, your metabolism has to work overtime for many hours afterward to help you recover. This leads to an intense, round-the-clock fat burn that you can’t get from programs that isolate muscle groups.
Hypertension is one of the most common worldwide diseases afflicting humans and is a major risk factor for stroke, myocardial infarction, vascular disease, and chronic kidney disease. Despite extensive research over the past several decades, the etiology of most cases of adult hypertension is still unknown, and control of blood pressure is suboptimal in the general population. Due to the associated morbidity and mortality and cost to society, preventing and treating hypertension is an important public health challenge. Fortunately, recent advances and trials in hypertension research are leading to an increased understanding of the pathophysiology of hypertension and the promise for novel pharmacologic and interventional treatments for this widespread disease.
When there is excess glucose present in the blood, as with type 2 diabetes, the kidneys react by flushing it out of the blood and into the urine. This results in more urine production and the need to urinate more frequently, as well as an increased risk of urinary tract infections (UTIs) in men and women. People with type 2 diabetes are twice as likely to get a UTI as people without the disease, and the risk is higher in women than in men.
You are more likely to develop type 2 diabetes if you are age 45 or older, have a family history of diabetes, or are overweight. Physical inactivity, race, and certain health problems such as high blood pressure also affect your chance of developing type 2 diabetes. You are also more likely to develop type 2 diabetes if you have prediabetes or had gestational diabetes when you were pregnant. Learn more about risk factors for type 2 diabetes.
Defining abnormally high blood pressure (BP) is extremely difficult and arbitrary. Furthermore, the relationship between systemic arterial pressure and morbidity appears to be quantitative rather than qualitative. A level for high BP must be agreed upon in clinical practice for screening patients with hypertension and for instituting diagnostic evaluation and initiating therapy. Because the risk to an individual patient may correlate with the severity of hypertension, a classification system is essential for making decisions about aggressiveness of treatment or therapeutic interventions. (See Presentation.)
The most current set of dietary guidelines for Americans encourages a diet that is plant-focused. Julie Upton, RD, of San Francisco, the cofounder of Appetite for Health, encourages a Mediterranean style of eating. The Mediterranean diet showcases fruits, veggies, whole grains, legumes, and seafood but has less meat, cheese, sugars, and sweets. Says Upton: “Not only is this plan helpful for your heart, but it also lowers risks for metabolic syndrome.”
