Type 2 DM is characterized by insulin resistance, which may be combined with relatively reduced insulin secretion.[11] 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.[2]

Insulin resistance also may increase your risk for metabolic syndrome. Insulin resistance is a condition in which the body can’t use its insulin properly. Insulin is a hormone that helps move blood sugar into cells where it’s used for energy. Insulin resistance can lead to high blood sugar levels, and it’s closely linked to overweight and obesity. Genetics (ethnicity and family history) and older age are other factors that may play a role in causing metabolic syndrome.
Blood pressure rises with aging and the risk of becoming hypertensive in later life is considerable.[37] Several environmental factors influence blood pressure. High salt intake raises the blood pressure in salt sensitive individuals; lack of exercise, obesity, and depression[38] can play a role in individual cases. The possible roles of other factors such as caffeine consumption,[39] and vitamin D deficiency[40] are less clear. Insulin resistance, which is common in obesity and is a component of syndrome X (or the metabolic syndrome), is also thought to contribute to hypertension.[41] One review suggests that sugar may play an important role in hypertension and salt is just an innocent bystander.[42]
Taking this a step further, I'd note that there are exercises that might not be self-limiting initially, but reach that point eventually. For example, with a beginner, a suspension trainer inverted row is not self-limiting at all; there are several important technique elements that a lifter needs to master because doing the exercise under conditions of fatigue.
Diabetes mellitus (DM), commonly referred to as diabetes, is a group of metabolic disorders in which there are high blood sugar levels over a prolonged period.[10] Symptoms of high blood sugar include frequent urination, increased thirst, and increased hunger.[2] If left untreated, diabetes can cause many complications.[2] Acute complications can include diabetic ketoacidosis, hyperosmolar hyperglycemic state, or death.[3] Serious long-term complications include cardiovascular disease, stroke, chronic kidney disease, foot ulcers, and damage to the eyes.[2]

A blood pressure reading measures both the systolic and diastolic forces, with the systolic pressure listed first. The numbers show your pressure in units of millimeters of mercury (mm Hg)—how high the pressure inside your arteries would be able to raise a column of mercury. For example, a reading of 120/80 mm Hg means a systolic pressure of 120 mm Hg and diastolic pressure of 80 mm Hg.
In addition to the problems with an increase in insulin resistance, the release of insulin by the pancreas may also be defective and suboptimal. In fact, there is a known steady decline in beta cell production of insulin in type 2 diabetes that contributes to worsening glucose control. (This is a major factor for many patients with type 2 diabetes who ultimately require insulin therapy.) Finally, the liver in these patients continues to produce glucose through a process called gluconeogenesis despite elevated glucose levels. The control of gluconeogenesis becomes compromised.
Now for the big surprise cause. There is another set of signaling molecules that have a huge impact on metabolic compensations during dieting. These compounds are present in your fat cells, and when fat is burned, they are released in significant concentrations. The shocking thing about these compounds is they did not come from your body. They are man made chemicals that you eat, put on your skin, drink in your water, and inhale through the air.

The brain is crucial in development of metabolic syndrome, modulating peripheral carbohydrate and lipid metabolism.[33][34] The metabolic syndrome can be induced by overfeeding with sugar or fructose, particularly concomitantly with high-fat diet.[36] The resulting oversupply of omega-6 fatty acids, particularly arachidonic acid (AA), is an important factor in the pathogenesis of metabolic syndrome.
"Brittle" diabetes, also known as unstable diabetes or labile diabetes, is a term that was traditionally used to describe the dramatic and recurrent swings in glucose levels, often occurring for no apparent reason in insulin-dependent diabetes. This term, however, has no biologic basis and should not be used.[39] Still, type 1 diabetes can be accompanied by irregular and unpredictable high blood sugar levels, frequently with ketosis, and sometimes with serious low blood sugar levels. Other complications include an impaired counterregulatory response to low blood sugar, infection, gastroparesis (which leads to erratic absorption of dietary carbohydrates), and endocrinopathies (e.g., Addison's disease).[39] These phenomena are believed to occur no more frequently than in 1% to 2% of persons with type 1 diabetes.[40]
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.

Cataracts and glaucoma are also more common among diabetics. It is also important to note that since the lens of the eye lets water through, if blood sugar concentrations vary a lot, the lens of the eye will shrink and swell with fluid accordingly. As a result, blurry vision is very common in poorly controlled diabetes. Patients are usually discouraged from getting a new eyeglass prescription until their blood sugar is controlled. This allows for a more accurate assessment of what kind of glasses prescription is required.
