Insulin is vital to patients with type 1 diabetes - they cannot live without a source of exogenous insulin. Without insulin, patients with type 1 diabetes develop severely elevated blood sugar levels. This leads to increased urine glucose, which in turn leads to excessive loss of fluid and electrolytes in the urine. Lack of insulin also causes the inability to store fat and protein along with breakdown of existing fat and protein stores. This dysregulation, results in the process of ketosis and the release of ketones into the blood. Ketones turn the blood acidic, a condition called diabetic ketoacidosis (DKA). Symptoms of diabetic ketoacidosis include nausea, vomiting, and abdominal pain. Without prompt medical treatment, patients with diabetic ketoacidosis can rapidly go into shock, coma, and even death may result.

Consistently high levels of insulin are associated with many harmful changes in the body prior to its manifesting as disease including chronic inflammation and damage to arterial walls, decreased excretion of salt by the kidneys, and thickening of the blood. People with metabolic disease also exhibit elevations in blood pressure and changes in their blood lipids, primarily with triglycerides (elevated) and good cholesterol or high density lipoprotein (HDL) (reduced). Problems associated with metabolic syndrome develop over time and usually worsen if left untreated.

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).

The earliest surviving work with a detailed reference to diabetes is that of Aretaeus of Cappadocia (2nd or early 3rd century CE). He described the symptoms and the course of the disease, which he attributed to the moisture and coldness, reflecting the beliefs of the "Pneumatic School". He hypothesized a correlation of diabetes with other diseases, and he discussed differential diagnosis from the snakebite which also provokes excessive thirst. His work remained unknown in the West until 1552, when the first Latin edition was published in Venice.[110]

Blood pressure was traditionally measured using a stethoscope and a blood pressure cuff (called a sphygmomanometer), a device that includes a cuff, a bulb, and a pressure dial that reads the pressure in millimeters of mercury (mm Hg). This is still considered the best method but, more commonly, devices that combine a blood pressure cuff with electronic sensors are used to measure blood pressure.
Let me give you an example of this. A person decides to follow a low calorie diet. They determine that their resting metabolic rate is 2000 calories per day. They decide, according to conventional wisdom, to reduce their daily calorie intake by 500 calories per day. Now they are consuming 1500 calories per day. They remain compliant and in a few weeks have lost a few pounds.

Enlarged heart. High blood pressure increases the amount of work for your heart. Like any heavily exercised muscle in your body, your heart grows bigger (enlarges) to handle the extra workload. The bigger your heart is, the more it demands oxygen-rich blood but the less able it is to maintain proper blood flow. As a result, you feel weak and tired and are not able to exercise or perform physical activities. Without treatment, your heart failure will only get worse.

First, the essence of MRT is to pack more exercise into less time. This is best achieved by employing high repetitions (15-20 reps per set, equating to about 60-65% 1RM) with minimal rest between sets4. The key to optimizing results is to train at maximal or near-maximal levels of effort. So take most sets to muscular failure or close to it (equating to a Rated Perceived Exertion [RPE] of 9 or 10 on a scale of 1-10). If you aren't sufficiently pushing yourself to complete each set, the metabolic effect and your results will suffer.

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.
The first WHO Global report on diabetes demonstrates that the number of adults living with diabetes has almost quadrupled since 1980 to 422 million adults. Factors driving this dramatic rise, which is largely on account of type 2 diabetes, include overweight and obesity. The new report calls upon governments to ensure that people are able to make healthy choices and that health systems are able to diagnose, treat and care for people with diabetes.
This is an incredibly important, but commonly overlooked factor that heavily influences a metabolic resistance training program's success. While you can usually get by with minimal equipment with a MRT program, body weight only can get old very quickly.  Fortunately, just adding a kettlebell, band, suspension trainer, barbell, or other implement can quickly expand your exercise selection pool.  It's important to realize that a little bit can go a long way, especially if you're training in a busy gym and can't monopolize pieces of equipment for too long without someone walking off with them!
If the amount of insulin available is insufficient, or if cells respond poorly to the effects of insulin (insulin insensitivity or insulin resistance), or if the insulin itself is defective, then glucose will not be absorbed properly by the body cells that require it, and it will not be stored appropriately in the liver and muscles. The net effect is persistently high levels of blood glucose, poor protein synthesis, and other metabolic derangements, such as acidosis.[60]

Approximately half of individuals with hypertension have OSA, and approximately half with OSA have hypertension. Ambulatory BP monitoring normally reveals a "dip" in BP of at least 10% during sleep. However, if a patient is a "nondipper," the chances that the patient has OSA is increased. Nondipping is thought to be caused by frequent apneic/hypopneic episodes that end with arousals associated with marked spikes in BP that last for several seconds. Apneic episodes are associated with striking increases in sympathetic nerve activity and enormous elevations of BP. Individuals with sleep apnea have increased cardiovascular mortality, in part likely related to the high incidence of hypertension.

The exact cause of metabolic syndrome is not known. Many features of the metabolic syndrome are associated with "insulin resistance." Insulin resistance means that the body does not use insulin efficiently to lower glucose and triglyceride levels. Insulin resistance is a combination of genetic and lifestyle factors. Lifestyle factors include diet, activity and perhaps interrupted sleep patterns (such as sleep apnea).
Moderate weight loss, in the range of 5 to ten percent of body weight, can help restore the body’s ability to recognize insulin and greatly reduce the chance of developing diabetes. It will also lower blood pressure and cholesterol. Aerobic exercise such as a brisk 30-minute daily walk can be highly effective in improving insulin levels, facilitating weight loss, and improving related symptoms. Most practitioners recommend 30-60 minutes daily of moderate intensity exercise on at least five days a week either divided throughout the day or all at once; the same benefit is achieved either way.
The relationship between type 2 diabetes and the main modifiable risk factors (excess weight, unhealthy diet, physical inactivity and tobacco use) is similar in all regions of the world. There is growing evidence that the underlying determinants of diabetes are a reflection of the major forces driving social, economic and cultural change: globalization, urbanization, population aging, and the general health policy environment.[74]
In animals, diabetes is most commonly encountered in dogs and cats. Middle-aged animals are most commonly affected. Female dogs are twice as likely to be affected as males, while according to some sources, male cats are also more prone than females. In both species, all breeds may be affected, but some small dog breeds are particularly likely to develop diabetes, such as Miniature Poodles.[123]

The pressure generated by the beating heart forces the blood forward and stretches the elastic walls of the arteries. In between heartbeats, as the heart muscle relaxes, the arterial walls snap back to their original shape, moving the blood forward to the body’s tissues. With hypertension, the pressure in the arteries is high enough to eventually produce damage to the blood vessels.

High blood pressure is a common and dangerous condition. Having high blood pressure means the pressure of the blood in your blood vessels is higher than it should be. But you can take steps to control your blood pressure and lower your risk of heart disease and stroke. About 1 of 3 U.S. adults—or about 75 million people—have high blood pressure.1 Only about half (54%) of these people have their high blood pressure under control.1 Many youth are also being diagnosed with high blood pressure.2 This common condition increases the risk for heart disease and stroke, two of the leading causes of death for Americans.3 Get more quick facts about high blood pressure, or learn more about high blood pressure in the United States.

This explains why my attempts at a low fat, high protein, high carb diet left me gaining weight all while eating 1000 calories per day! Those 1000 calories were simply fueling my brain and then getting shuttled into my fat cells. If you are not insulin resistant, then this diet may be just the thing you need to shed some short term pounds (although I never recommend a 1000 calorie diet!- more on that later), but to me it caused metabolic chaos.

The United Kingdom Prospective Diabetes Study (UKPDS) was a clinical study conducted by Z that was published in The Lancet in 1998. Around 3,800 people with type 2 diabetes were followed for an average of ten years, and were treated with tight glucose control or the standard of care, and again the treatment arm had far better outcomes. This confirmed the importance of tight glucose control, as well as blood pressure control, for people with this condition.[86][132][133]
In Europe hypertension occurs in about 30-45% of people as of 2013.[12] In 1995 it was estimated that 43 million people (24% of the population) in the United States had hypertension or were taking antihypertensive medication.[141] By 2004 this had increased to 29%[142][143] and further to 32% (76 million US adults) by 2017.[7] In 2017, with the change in definitions for hypertension, 46% of people in the United States are affected.[7] African-American adults in the United States have among the highest rates of hypertension in the world at 44%.[144] It is also more common in Filipino Americans and less common in US whites and Mexican Americans.[6][145] Differences in hypertension rates are multifactorial and under study.[146]

The word diabetes (/ˌdaɪ.əˈbiːtiːz/ or /ˌdaɪ.əˈbiːtɪs/) comes from Latin diabētēs, which in turn comes from Ancient Greek διαβήτης (diabētēs), which literally means "a passer through; a siphon".[111] Ancient Greek physician Aretaeus of Cappadocia (fl. 1st century CE) used that word, with the intended meaning "excessive discharge of urine", as the name for the disease.[112][113] Ultimately, the word comes from Greek διαβαίνειν (diabainein), meaning "to pass through,"[111] which is composed of δια- (dia-), meaning "through" and βαίνειν (bainein), meaning "to go".[112] The word "diabetes" is first recorded in English, in the form diabete, in a medical text written around 1425.
The prevalence of metabolic syndrome increases with age, with about 40% of people older than 60 years meeting the criteria. [26] However, metabolic syndrome can no longer be considered a disease of only adult populations. Alarmingly, metabolic syndrome and diabetes mellitus are increasingly prevalent in the pediatric population, again in parallel with a rise in obesity. [50]

Because some medications, such as over-the-counter cold medicines, pain medications, antidepressants, birth control pills and others, can raise your blood pressure, it might be a good idea to bring a list of medications and supplements you take to your doctor's appointment. Don't stop taking any prescription medications that you think may affect your blood pressure without your doctor's advice.
