Effective lifestyle modification may lower blood pressure as much as an individual antihypertensive medication. Combinations of two or more lifestyle modifications can achieve even better results.[87] There is considerable evidence that reducing dietary salt intake lowers blood pressure, but whether this translates into a reduction in mortality and cardiovascular disease remains uncertain.[96] Estimated sodium intake ≥6g/day and <3g/day are both associated with high risk of death or major cardiovascular disease, but the association between high sodium intake and adverse outcomes is only observed in people with hypertension.[97] Consequently, in the absence of results from randomized controlled trials, the wisdom of reducing levels of dietary salt intake below 3g/day has been questioned.[96]
Usually, there are no immediate physical symptoms of metabolic syndrome. People with metabolic syndrome do have a tendency to be overweight, especially around the abdomen – having an “apple shape.” Moreover, since this condition is associated with insulin resistance, individuals with metabolic syndrome may display some of the clinical features associated with an increase in the production of insulin. For instance, women may experience cysts on their ovaries (metabolic syndrome is associated with polycystic ovarian syndrome) and irregular periods. Individuals can have an increased incidence of skin tags, benign raised growths of skin that usually appear increases on the neck and back. In addition, they can exhibit acanthosis nigricans – a pigmentation of the skin, which appears discolored or dirty over the back of the neck and underarms.
In 1977 and 1978, Gerald B. Phillips developed the concept that risk factors for myocardial infarction concur to form a "constellation of abnormalities" (i.e., glucose intolerance, hyperinsulinemia, hypercholesterolemia, hypertriglyceridemia, and hypertension) associated not only with heart disease, but also with aging, obesity and other clinical states. He suggested there must be an underlying linking factor, the identification of which could lead to the prevention of cardiovascular disease; he hypothesized that this factor was sex hormones.[66][67]
The oral glucose tolerance test (OGTT), or glucose tolerance test is a blood test used (not routinely however) to diagnose diabetes, and gestational diabetes. Information in regard to reliability of the oral glucose tolerance test is important, as some conditions (common cold), or food (caffeine), or lifestyle habits (smoking) may alter the results of the oral glucose tolerance test.

Blood pressure goals are generally set lower than 130/80. Some blood pressure medications offer more benefits than simply lowering blood pressure. For example, a class of blood pressure drugs called ACE inhibitors has been found to also reduce the levels of insulin resistance and actually deter the development of type 2 diabetes. This is an important consideration when discussing the choice blood pressure drugs in the metabolic syndrome.
14 November 2018. On World Diabetes Day 2018, WHO joins partners around the world to highlight the impact diabetes has on families and the role of family members in supporting prevention, early diagnosis and good management of diabetes. More than 400 million people live with diabetes worldwide, and the prevalence is predicted to continue rising if current trends prevail. Diabetes is a major cause of premature dying, blindness, kidney failure, heart attack, stroke and lower limb amputation. It was the seventh leading cause of death in 2016.
The previous definitions of the metabolic syndrome by the International Diabetes Federation[40] and the revised National Cholesterol Education Program are very similar and they identify individuals with a given set of symptoms as having metabolic syndrome. There are two differences, however: the IDF definition states that if body mass index (BMI) is greater than 30 kg/m2, central obesity can be assumed, and waist circumference does not need to be measured. However, this potentially excludes any subject without increased waist circumference if BMI is less than 30. Conversely, the NCEP definition indicates that metabolic syndrome can be diagnosed based on other criteria. Also, the IDF uses geography-specific cut points for waist circumference, while NCEP uses only one set of cut points for waist circumference regardless of geography. These two definitions are much more similar than the original NCEP and WHO definitions.

Since cardiovascular disease is a serious complication associated with diabetes, some have recommended blood pressure levels below 130/80 mmHg.[89] However, evidence supports less than or equal to somewhere between 140/90 mmHg to 160/100 mmHg; the only additional benefit found for blood pressure targets beneath this range was an isolated decrease in stroke risk, and this was accompanied by an increased risk of other serious adverse events.[90][91] A 2016 review found potential harm to treating lower than 140 mmHg.[92] Among medications that lower blood pressure, angiotensin converting enzyme inhibitors (ACEIs) improve outcomes in those with DM while the similar medications angiotensin receptor blockers (ARBs) do not.[93] Aspirin is also recommended for people with cardiovascular problems, however routine use of aspirin has not been found to improve outcomes in uncomplicated diabetes.[94]
Just briefly I want to mention something for the more savvy readers out there. Many, who are well versed in metabolism, will immediately point out that if you lose weight, then of course you are going to be burning less calories because you have less body tissue. True. But what research shows, and my clinical experience validates, is that the reduced rate of metabolic output goes far beyond what would be predicted from loss of fat mass or muscle mass.
The clinical value of using "metabolic syndrome" as a diagnosis has previously been debated due to different sets of conflicting and incomplete diagnostic criteria. These concerns have led the American Diabetes Association and the European Association for the Study of Diabetes to issue a joint statement identifying eight major concerns on the clinical utility of the metabolic syndrome diagnosis.[69] The principal argument has been that when confounding factors such as obesity are accounted for, diagnosis of the metabolic syndrome has a negligible association with the risk of heart disease.[70]
Eating healthfully. The Dietary Approaches to Stop Hypertension (DASH) diet and the Mediterranean diet, like many healthy-eating plans, limit unhealthy fats and emphasize fruits, vegetables, fish and whole grains. Both dietary approaches have been found to offer important health benefits — in addition to weight loss — for people who have components of metabolic syndrome.
