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.
When you have diabetes, it’s important to avoid eating many packaged, processed snacks such as cookies, chips, cake, granola bars, and the like, in lieu of fresh, whole foods, like fiber-rich fruits, veggies, and whole grains. (27) Eating foods high in fiber can help keep blood sugar levels steady and fill you up, potentially promoting weight loss and improving insulin sensitivity. (28)

This is true for two reasons. Not only are many fad diets low fat, but they are also low calorie. Your body is not stupid! It can see that you are not taking in enough energy to support your basal metabolic rate. Your basal metabolic rate is the number of calories that your body requires to run your heart, brain, liver, digestive system, lungs etc. This critical number is very responsive to the environment because back in the good old days food wasn’t widely available. If you weren’t able to find food for a few days then your whole system slowed down to require less calories and protect you from dying.
Abnormal cholesterol and triglyceride levels. If you have low levels of high-density lipoprotein (HDL), or "good," cholesterol, your risk of type 2 diabetes is higher. Triglycerides are another type of fat carried in the blood. People with high levels of triglycerides have an increased risk of type 2 diabetes. Your doctor can let you know what your cholesterol and triglyceride levels are.

Insulin is a hormone that is produced by specialized cells (beta cells) of the pancreas. (The pancreas is a deep-seated organ in the abdomen located behind the stomach.) In addition to helping glucose enter the cells, insulin is also important in tightly regulating the level of glucose in the blood. After a meal, the blood glucose level rises. In response to the increased glucose level, the pancreas normally releases more insulin into the bloodstream to help glucose enter the cells and lower blood glucose levels after a meal. When the blood glucose levels are lowered, the insulin release from the pancreas is turned down. It is important to note that even in the fasting state there is a low steady release of insulin than fluctuates a bit and helps to maintain a steady blood sugar level during fasting. In normal individuals, such a regulatory system helps to keep blood glucose levels in a tightly controlled range. As outlined above, in patients with diabetes, the insulin is either absent, relatively insufficient for the body's needs, or not used properly by the body. All of these factors cause elevated levels of blood glucose (hyperglycemia). https://i.ytimg.com/vi/03Ar9vo6VbM/hqdefault.jpg?sqp
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).
Serum creatinine is measured to assess for the presence of kidney disease, which can be either the cause or the result of hypertension. Serum creatinine alone may overestimate glomerular filtration rate and recent guidelines advocate the use of predictive equations such as the Modification of Diet in Renal Disease (MDRD) formula to estimate glomerular filtration rate (eGFR).[27] eGFR can also provide a baseline measurement of kidney function that can be used to monitor for side effects of certain anti-hypertensive drugs on kidney function. Additionally, testing of urine samples for protein is used as a secondary indicator of kidney disease. Electrocardiogram (EKG/ECG) testing is done to check for evidence that the heart is under strain from high blood pressure. It may also show whether there is thickening of the heart muscle (left ventricular hypertrophy) or whether the heart has experienced a prior minor disturbance such as a silent heart attack. A chest X-ray or an echocardiogram may also be performed to look for signs of heart enlargement or damage to the heart.[23]
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.
In most people with established essential hypertension, increased resistance to blood flow (total peripheral resistance) accounts for the high pressure while cardiac output remains normal.[52] There is evidence that some younger people with prehypertension or 'borderline hypertension' have high cardiac output, an elevated heart rate and normal peripheral resistance, termed hyperkinetic borderline hypertension.[53] These individuals develop the typical features of established essential hypertension in later life as their cardiac output falls and peripheral resistance rises with age.[53] Whether this pattern is typical of all people who ultimately develop hypertension is disputed.[54] The increased peripheral resistance in established hypertension is mainly attributable to structural narrowing of small arteries and arterioles,[55] although a reduction in the number or density of capillaries may also contribute.[56]
Another common endocrine cause is oral contraceptive use. Activation of the renin-angiotensin-aldosterone system (RAAS) is the likely mechanism, because hepatic synthesis of angiotensinogen is induced by the estrogen component of oral contraceptives. Approximately 5% of women taking oral contraceptives may develop hypertension, which abates within 6 months after discontinuation. The risk factors for oral contraceptive–associated hypertension include mild renal disease, familial history of essential hypertension, age older than 35 years, and obesity. It would be better to group oral contraceptives and steroids with drug-induced hypertension (see Table 1, below).
The previous definitions of the metabolic syndrome by the International Diabetes Federation[40] and the revised National Cholesterol Education Program are very similar and they identify individuals with a given set of symptoms as having metabolic syndrome. There are two differences, however: the IDF definition states that if body mass index (BMI) is greater than 30 kg/m2, central obesity can be assumed, and waist circumference does not need to be measured. However, this potentially excludes any subject without increased waist circumference if BMI is less than 30. Conversely, the NCEP definition indicates that metabolic syndrome can be diagnosed based on other criteria. Also, the IDF uses geography-specific cut points for waist circumference, while NCEP uses only one set of cut points for waist circumference regardless of geography. These two definitions are much more similar than the original NCEP and WHO definitions.
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.
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.
As of 2016, 422 million people have diabetes worldwide,[101] up from an estimated 382 million people in 2013[17] and from 108 million in 1980.[101] Accounting for the shifting age structure of the global population, the prevalence of diabetes is 8.5% among adults, nearly double the rate of 4.7% in 1980.[101] Type 2 makes up about 90% of the cases.[16][18] Some data indicate rates are roughly equal in women and men,[18] but male excess in diabetes has been found in many populations with higher type 2 incidence, possibly due to sex-related differences in insulin sensitivity, consequences of obesity and regional body fat deposition, and other contributing factors such as high blood pressure, tobacco smoking, and alcohol intake.[102][103]
Though it may be transient, untreated GDM can damage the health of the fetus or mother. Risks to the baby include macrosomia (high birth weight), congenital heart and central nervous system abnormalities, and skeletal muscle malformations. Increased levels of insulin in a fetus's blood may inhibit fetal surfactant production and cause infant respiratory distress syndrome. A high blood bilirubin level may result from red blood cell destruction. In severe cases, perinatal death may occur, most commonly as a result of poor placental perfusion due to vascular impairment. Labor induction may be indicated with decreased placental function. A caesarean section may be performed if there is marked fetal distress or an increased risk of injury associated with macrosomia, such as shoulder dystocia.[51]
Insulin is a fat storage hormone, it works to shuttle the sugar from your blood stream into your fat cells to store for later. Insulin has a number of other reproductive functions and has effects on skin health, cravings and the like. Insulin levels naturally increase after eating a meal that contains carbohydrates, dairy or protein. If you are insulin resistant then you can have an elevated level of insulin when you are fasting, or you can experience too much insulin release in response to those foods. This can trap your body in fat storage mode and inhibit fat loss.
"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]
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. https://i.ytimg.com/vi/xQRE2ht3elA/maxresdefault.jpg

Exogenous administration of the other steroids used for therapeutic purposes also increases blood pressure (BP), especially in susceptible individuals, mainly by volume expansion. Nonsteroidal anti-inflammatory drugs (NSAIDs) may also have adverse effects on BP. NSAIDs block both cyclooxygenase-1 (COX-1) and COX-2 enzymes. The inhibition of COX-2 can inhibit its natriuretic effect, which, in turn, increases sodium retention. NSAIDs also inhibit the vasodilating effects of prostaglandins and the production of vasoconstricting factors—namely, endothelin-1. These effects can contribute to the induction of hypertension in a normotensive or controlled hypertensive patient.

Metabolic syndrome (also known as metabolic syndrome X) is a grouping of cardiac risk factors that result from insulin resistance (when the body's tissues do not respond normally to insulin). A person with metabolic syndrome has a greatly increased risk of developing type 2 diabetes, cardiovascular disease and premature death. In fact, another name for metabolic syndrome is pre-diabetes. https://www.clairekerslake.com/wp-content/uploads/2011/11/candles.jpg
Some risks of the keto diet include low blood sugar, negative medication interactions, and nutrient deficiencies. (People who should avoid the keto diet include those with kidney damage or disease, women who are pregnant or breast-feeding, and those with or at a heightened risk for heart disease due to high blood pressure, high cholesterol, or family history. (40)
The best way to prevent metabolic syndrom is to adopt heart-healthy lifestyle changes. Make sure to schedule routine doctor visits to keep track of your cholesterol, blood pressure, and blood sugar levels. Speak with your doctor about a blood test called a lipoprotein panel, which shows your levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.
In a meta-analysis of pooled data from 19 prospective cohort studies involving 762,393 patients, Huang et al reported that, after adjustment for multiple cardiovascular risk factors, prehypertension was associated with a 66% increased risk for stroke, compared with an optimal blood pressure (< 120/80 mm Hg). [41, 42] Patients in the high range of prehypertension (130-139/85-89 mm Hg) had a 95% increased risk of stroke, compared with a 44% increased risk for those in the low range of prehypertension (120-129/80-84 mm Hg). [41, 42]
In the Framingham Heart Study, the age-adjusted risk of congestive heart failure was 2.3 times higher in men and 3 times higher in women when the highest BP was compared to the lowest BP. [44] Multiple Risk Factor Intervention Trial (MRFIT) data showed that the relative risk for coronary artery disease mortality was 2.3 to 6.9 times higher for persons with mild to severe hypertension than it was for persons with normal BP. [45] The relative risk for stroke ranged from 3.6 to 19.2. The population-attributable risk percentage for coronary artery disease varied from 2.3 to 25.6%, whereas the population-attributable risk for stroke ranged from 6.8-40%.
Physical changes: If something in your body changes, you may begin experiencing issues throughout your body. High blood pressure may be one of those issues. For example, it’s thought that changes in your kidney function due to aging may upset the body’s natural balance of salts and fluid. This change may cause your body’s blood pressure to increase.

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).
A positive result, in the absence of unequivocal high blood sugar, should be confirmed by a repeat of any of the above methods on a different day. It is preferable to measure a fasting glucose level because of the ease of measurement and the considerable time commitment of formal glucose tolerance testing, which takes two hours to complete and offers no prognostic advantage over the fasting test.[66] According to the current definition, two fasting glucose measurements above 7.0 mmol/l (126 mg/dl) is considered diagnostic for diabetes mellitus.
Usually, there are no immediate physical symptoms. Medical problems associated with the metabolic syndrome develop over time. If you are unsure if you have metabolic syndrome, see your healthcare provider. He or she will be able to make the diagnosis by obtaining the necessary tests, including blood pressure, lipid profile (triglycerides and HDL), and blood glucose.
Type 1 diabetes occurs because the insulin-producing cells of the pancreas (beta cells) are damaged. In type 1 diabetes, the pancreas makes little or no insulin, so sugar cannot get into the body's cells for use as energy. People with type 1 diabetes must use insulin injections to control their blood glucose. Type 1 is the most common form of diabetes in people who are under age 30, but it can occur at any age. Ten percent of people with diabetes are diagnosed with type 1.

Eating healthfully. The Dietary Approaches to Stop Hypertension (DASH) diet and the Mediterranean diet, like many healthy-eating plans, limit unhealthy fats and emphasize fruits, vegetables, fish and whole grains. Both dietary approaches have been found to offer important health benefits — in addition to weight loss — for people who have components of metabolic syndrome.
