The prevailing opinion is that all of these markers are signs of insulin resistance, meaning the diminished ability of a given amount of insulin to exert its normal effect. When insulin resistance develops, it can impact metabolic processes in many ways, resulting in the specific markers listed above. However, different individuals respond to insulin resistance in different ways. Also, the time frame in which certain signs develop varies. This variability makes defining—and treating—metabolic syndrome tricky.

What causes high cholesterol? High cholesterol is a risk factor for heart attacks and coronary heart disease, because it builds up in the arteries, narrowing them. It does not usually have any symptoms, and many people do not know they have it. We look at healthy levels and ranges of cholesterol, at ways to prevent it, and medications to treat it. Read now
When you are first diagnosed with hypertension, you can expect a period of time when you will be seeing your doctor more often than usual. You will need some baseline testing to look for an underlying cause for your hypertension, and you will probably need several medical visits to determine whether lifestyle adjustments or medication will be effective in helping you reach your optimal blood pressure.
Diabetes mellitus is classified into four broad categories: type 1, type 2, gestational diabetes, and "other specific types".[11] The "other specific types" are a collection of a few dozen individual causes.[11] Diabetes is a more variable disease than once thought and people may have combinations of forms.[37] The term "diabetes", without qualification, usually refers to diabetes mellitus.
The term "diabetes" or "to pass through" was first used in 230 BCE by the Greek Apollonius of Memphis.[108] The disease was considered rare during the time of the Roman empire, with Galen commenting he had only seen two cases during his career.[108] This is possibly due to the diet and lifestyle of the ancients, or because the clinical symptoms were observed during the advanced stage of the disease. Galen named the disease "diarrhea of the urine" (diarrhea urinosa).[110]

Mind/Body: It is important to attend to stress in positive ways. Rather than using alcohol, tobacco, or television, try breathing exercises. They are simple, free, and right under your nose. Dr. Weil has compiled ten ways to reduce stress and promote relaxation, calm and peace within yourself. Some techniques take practice, and most require some commitment on your part to achieve results. However, the results are well worth the effort.

Central obesity is a key feature of the syndrome, being both a sign and a cause, in that the increasing adiposity often reflected in high waist circumference may both result from and contribute to insulin resistance. However, despite the importance of obesity, patients who are of normal weight may also be insulin-resistant and have the syndrome.[27]
Most people who have metabolic syndrome have insulin resistance. The body makes insulin to move glucose (sugar) into cells for use as energy. Obesity, commonly found in people with metabolic syndrome, makes it more difficult for cells in the body to respond to insulin. If the body can’t make enough insulin to override the resistance, the blood sugar level increases, causing type 2 diabetes. Metabolic syndrome may be a start of the development of type 2 diabetes.
Diabetes mellitus occurs throughout the world but is more common (especially type 2) in more developed countries. The greatest increase in rates has however been seen in low- and middle-income countries,[101] where more than 80% of diabetic deaths occur.[105] The fastest prevalence increase is expected to occur in Asia and Africa, where most people with diabetes will probably live in 2030.[106] The increase in rates in developing countries follows the trend of urbanization and lifestyle changes, including increasingly sedentary lifestyles, less physically demanding work and the global nutrition transition, marked by increased intake of foods that are high energy-dense but nutrient-poor (often high in sugar and saturated fats, sometimes referred to as the "Western-style" diet).[101][106] The global prevalence of diabetes might increase by 55% between 2013 and 2035.[101]
Excess abdominal fat leads to excess free fatty acids in the portal vein, increasing fat accumulation in the liver. Fat also accumulates in muscle cells. Insulin resistance develops, with hyperinsulinemia. Glucose metabolism is impaired, and dyslipidemias and hypertension develop. Serum uric acid levels are typically elevated (increasing risk of gout), and a prothrombotic state (with increased levels of fibrinogen and plasminogen activator inhibitor I) and an inflammatory state develop.
Although many processes are involved in this, your thyroid is one of them. The thyroid is a small gland at the front of the neck that releases hormones that control your metabolic rate and the functions of nearly every cell in the body. Going low calorie is a great way to make you feel cold, tired, constipated and frumpy because your brain uses your thyroid to slow everything down!
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.”
Interestingly enough, some data suggests that consumption of sodas (diet or regular) and other products containing high-fructose corn syrup (HFCS) like salad dressings and ketchup, jams, jellies, ice cream and many more foods may be linked to obesity, insulin resistance, and metabolic syndrome in both adults and children. Interrupted sleep patterns (such as sleep apnea) may also be a factor in increasing the incidence of insulin resistance and metabolic syndrome in the adult population.
Metabolic syndrome is a cluster of metabolic risk factors that come together in a single individual. These metabolic factors include insulin resistance, hypertension (high blood pressure), cholesterol abnormalities, and an increased risk for blood clotting. Affected individuals are most often overweight or obese. An association between certain metabolic disorders and cardiovascular disease has been known since the 1940s.
Metabolic syndrome promotes coronary heart disease through several mechanisms. It increases the thrombogenicity of circulating blood, in part by raising plasminogen activator type 1 and adipokine levels, and it causes endothelial dysfunction. [14] Metabolic syndrome may also increase cardiovascular risks by increasing arterial stiffness. [15] Additional mechanisms include oxidative stress, [16] which has been associated with numerous components of metabolic syndrome. [17]
The distribution of adipose tissue appears to affect its role in metabolic syndrome. Fat that is visceral or intra-abdominal correlates with inflammation, whereas subcutaneous fat does not. There are a number of potential explanations for this, including experimental observations that omental fat is more resistant to insulin and may result in a higher concentration of toxic free fatty acids in the portal circulation. [21]
Creatinine is a chemical waste molecule that is generated from muscle metabolism. Creatinine is produced from creatine, a molecule of major importance for energy production in muscles. Creatinine has been found to be a fairly reliable indicator of kidney function. As the kidneys become impaired the creatinine level in the blood will rise. Normal levels of creatinine in the blood vary from gender and age of the individual.

Glucagon is a hormone that causes the release of glucose from the liver (for example, it promotes gluconeogenesis). Glucagon can be lifesaving and every patient with diabetes who has a history of hypoglycemia (particularly those on insulin) should have a glucagon kit. Families and friends of those with diabetes need to be taught how to administer glucagon, since obviously the patients will not be able to do it themselves in an emergency situation. Another lifesaving device that should be mentioned is very simple; a medic-alert bracelet should be worn by all patients with diabetes.
Cortisol reactivity, an index of hypothalamic-pituitary-adrenal function, may be another mechanism by which psychosocial stress is associated with future hypertension. [20] In a prospective sub-study of the Whitehall II cohort, with 3 years follow-up of an occupational cohort in previously healthy patients, investigators reported 15.9% of the patient sample developed hypertension in response to laboratory-induced mental stressors and found an association between cortisol stress reactivity and incident hypertension.
