Type 2 DM is characterized by insulin resistance, which may be combined with relatively reduced insulin secretion. 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.
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.
Hypertension may be primary, which may develop as a result of environmental or genetic causes, or secondary, which has multiple etiologies, including renal, vascular, and endocrine causes. Primary or essential hypertension accounts for 90-95% of adult cases, and a small percentage of patients (2-10%) have a secondary cause. Hypertensive emergencies are most often precipitated by inadequate medication or poor compliance.
When the glucose concentration in the blood remains high over time, the kidneys will reach a threshold of reabsorption, and glucose will be excreted in the urine (glycosuria). This increases the osmotic pressure of the urine and inhibits reabsorption of water by the kidney, resulting in increased urine production (polyuria) and increased fluid loss. Lost blood volume will be replaced osmotically from water held in body cells and other body compartments, causing dehydration and increased thirst (polydipsia).
Type 2 diabetes was also previously referred to as non-insulin dependent diabetes mellitus (NIDDM), or adult-onset diabetes mellitus (AODM). In type 2 diabetes, patients can still produce insulin, but do so relatively inadequately for their body's needs, particularly in the face of insulin resistance as discussed above. In many cases this actually means the pancreas produces larger than normal quantities of insulin. A major feature of type 2 diabetes is a lack of sensitivity to insulin by the cells of the body (particularly fat and muscle cells). http://www.clairekerslake.com/wp-content/uploads/2014/03/ipad_new.png
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.
Development of metabolic syndrome depends on distribution as well as amount of fat. Excess fat in the abdomen (called apple shape), particularly when it results in a high waist-to-hip ratio (reflecting a relatively low muscle-to-fat mass ratio), increases risk. The syndrome is less common among people who have excess subcutaneous fat around the hips (called pear shape) and a low waist-to-hip ratio (reflecting a higher muscle-to-fat mass ratio). https://www.healthshare.com.au/storage/avatars/patricia-durning.jpg.60x60_q85_box-0,0,100,100.jpg
Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas to normalize the glucose level by promoting the uptake of glucose into body cells. In patients with diabetes, the absence of insufficient production of or lack of response to insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
Leading a healthy lifestyle now can reduce your risk of developing the health risks associated with metabolic syndrome as you get older. Effective prevention includes eating a healthy diet by following Canada's Food Guide and exercising for 150 minutes every week. Seeing your doctor for routine check ups and checking your blood glucose levels, blood pressure, blood cholesterol, and weight will help you monitor your health.

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.
In addition, metabolic syndrome has been implicated in the pathophysiology of several other diseases, including obstructive sleep apnea. Breast cancer has also been linked to metabolic syndrome, possibly through dysregulation of the plasminogen activator inhibitor-1 (PAI-1) cycle.  Additional studies have linked metabolic syndrome with cancers of the colon, gallbladder, kidney, and, possibly, prostate gland.  Evidence is emerging of an association with psoriasis. [66, 67]
Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. Insulin is a hormone that helps the glucose get into your cells to give them energy. With type 1 diabetes, your body does not make insulin. With type 2 diabetes, the more common type, your body does not make or use insulin well. Without enough insulin, the glucose stays in your blood. You can also have prediabetes. This means that your blood sugar is higher than normal but not high enough to be called diabetes. Having prediabetes puts you at a higher risk of getting type 2 diabetes.
