Type 2 DM is primarily due to lifestyle factors and genetics. A number of lifestyle factors are known to be important to the development of type 2 DM, including obesity (defined by a body mass index of greater than 30), lack of physical activity, poor diet, stress, and urbanization. Excess body fat is associated with 30% of cases in those of Chinese and Japanese descent, 60–80% of cases in those of European and African descent, and 100% of Pima Indians and Pacific Islanders. Even those who are not obese often have a high waist–hip ratio.
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.

As you lose weight your leptin levels drop, signalling to your body that it should probably start to slow things down. In this case you can feel hungry all of the time, but also sluggish and weight loss stops. Some people even see weight gain which can either send you into frustration nation… or alternatively lead you to cut more calories and drive your metabolic rate and gut hormone signalling down even further! Yikes!

If you’ve been told that you have metabolic syndrome (sometimes called cardiometabolic syndrome), it means that you have several of these health problems. Together, they put you at much greater risk for heart attack, stroke and type 2 diabetes. In general, someone who has metabolic syndrome is twice as likely to develop heart disease and five times as likely to develop diabetes as a person who doesn’t have this grouping of health issues. Unfortunately, amid rising obesity rates in the U.S., this syndrome is becoming more common. Alarmingly, one out of 10 teens may have it.
Research shows that Western diet habits are a factor in development of metabolic syndrome, with high consumption of food that is not biochemically suited to humans. Weight gain is associated with metabolic syndrome. Rather than total adiposity, the core clinical component of the syndrome is visceral and/or ectopic fat (i.e., fat in organs not designed for fat storage) whereas the principal metabolic abnormality is insulin resistance. The continuous provision of energy via dietary carbohydrate, lipid, and protein fuels, unmatched by physical activity/energy demand creates a backlog of the products of mitochondrial oxidation, a process associated with progressive mitochondrial dysfunction and insulin resistance.
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.
The discussion of weight and weight loss has evolved dramatically over the past 10-15 years. In some ways this has been for the better, but in other ways for the worse. I am incredibly grateful that the discussion has moved beyond just the calories in, calories out model (because we all know at this point that that is crap!). This notion though, that calories are not the key point of the equation has spurred a $66.3 BILLION dollar diet industry. Whether this is diet pills, the gym, or other contraptions that promise to shake your last 10lbs off the general understanding is that people are being taken for a very expensive ride. At the same time though, more North American’s are in the over weight and obese category than ever. So what digs?
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. Failing to take the prescribed drugs, is an important cause of resistant hypertension. Resistant hypertension may also result from chronically high activity of the autonomic nervous system, an effect known as "neurogenic hypertension". Electrical therapies that stimulate the baroreflex are being studied as an option for lowering blood pressure in people in this situation.
The metabolic syndrome quintuples the risk of type 2 diabetes mellitus. Type 2 diabetes is considered a complication of metabolic syndrome. In people with impaired glucose tolerance or impaired fasting glucose, presence of metabolic syndrome doubles the risk of developing type 2 diabetes. It is likely that prediabetes and metabolic syndrome denote the same disorder, defining it by the different sets of biological markers.
In autoimmune diseases, such as type 1 diabetes, the immune system mistakenly manufactures antibodies and inflammatory cells that are directed against and cause damage to patients' own body tissues. In persons with type 1 diabetes, the beta cells of the pancreas, which are responsible for insulin production, are attacked by the misdirected immune system. It is believed that the tendency to develop abnormal antibodies in type 1 diabetes is, in part, genetically inherited, though the details are not fully understood.
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.
The most common side effects of anti-hypertensive medications include hypotension (low blood pressure) and dizziness. These effects are the result of the excessive lowering of blood pressure, and they can be alleviated if your doctor adjusts your medication dose. Each drug and medication category also has its own unique side effects, which you should familiarize yourself with when you begin taking the medication (check patient information provided by your pharmacy, or ask the pharmacist herself).
When a blood pressure reading is taken, the higher number represents the systolic pressure and the lower number represents the diastolic pressure. For example: 120/80 (120 over 80) in an adult means that the systolic pressure is 120 and the diastolic pressure is 80. As kids grow, their blood pressure increases from a systolic pressure of about 70–90 (as babies) to adult values (when they're teens).
Weight loss surgery in those with obesity and type two diabetes is often an effective measure. Many are able to maintain normal blood sugar levels with little or no medications following surgery and long-term mortality is decreased. There is, however, a short-term mortality risk of less than 1% from the surgery. The body mass index cutoffs for when surgery is appropriate are not yet clear. It is recommended that this option be considered in those who are unable to get both their weight and blood sugar under control.
Not so anymore. Thanks to the rising obesity epidemic in young people, kids and teens are getting these conditions — and they're getting them earlier than ever before. Some estimates say that nearly 1 in 10 teens — and over a third of obese teens — have metabolic syndrome. And a study of 375 second- and third-graders found that 5% had metabolic syndrome and 45% had one or two risk factors for it.
Metformin is generally recommended as a first line treatment for type 2 diabetes, as there is good evidence that it decreases mortality. It works by decreasing the liver's production of glucose. Several other groups of drugs, mostly given by mouth, may also decrease blood sugar in type II DM. These include agents that increase insulin release, agents that decrease absorption of sugar from the intestines, and agents that make the body more sensitive to insulin. When insulin is used in type 2 diabetes, a long-acting formulation is usually added initially, while continuing oral medications. Doses of insulin are then increased to effect.
Hypertension or high blood pressure is a chronic medical condition in which the pressure or tension in the arteries is elevated. It is often called the "silent disease" as it has no symptoms and can go undetected for years, damaging your tissues and vital organs. If you have hypertension, your heart works harder than it should to pump blood to your tissues and organs. If this pressure isn't controlled, your heart enlarges and your arteries become scarred and hardened. Eventually, your overworked heart may not be able to pump and transport blood properly through these arteries. This can result in heart disease, kidney disease, the hardening of the arteries, eye damage, and stroke. Hypertension can be caused by a number of factors including your genes, underlying disease and lifestyle.
