Management of type 2 diabetes focuses on lifestyle interventions, lowering other cardiovascular risk factors, and maintaining blood glucose levels in the normal range.[24] Self-monitoring of blood glucose for people with newly diagnosed type 2 diabetes may be used in combination with education,[70] however the benefit of self monitoring in those not using multi-dose insulin is questionable.[24][71] In those who do not want to measure blood levels, measuring urine levels may be done.[70] Managing other cardiovascular risk factors, such as hypertension, high cholesterol, and microalbuminuria, improves a person's life expectancy.[24] Decreasing the systolic blood pressure to less than 140 mmHg is associated with a lower risk of death and better outcomes.[72] Intensive blood pressure management (less than 130/80 mmHg) as opposed to standard blood pressure management (less than 140-160 mmHg systolic to 85–100 mmHg diastolic) results in a slight decrease in stroke risk but no effect on overall risk of death.[73]
Random blood sugar test. A blood sample will be taken at a random time. Blood sugar values are expressed in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Regardless of when you last ate, a random blood sugar level of 200 mg/dL (11.1 mmol/L) or higher suggests diabetes, especially when coupled with any of the signs and symptoms of diabetes, such as frequent urination and extreme thirst.
Classic symptoms of DM are polyuria, polydipsia, and weight loss. In addition, patients with hyperglycemia often have blurred vision, increased food consumption (polyphagia), and generalized weakness. When a patient with type 1 DM loses metabolic control (such as during infections or periods of noncompliance with therapy), symptoms of diabetic ketoacidosis occur. These may include nausea, vomiting, dizziness on arising, intoxication, delirium, coma, or death. Chronic complications of hyperglycemia include retinopathy and blindness, peripheral and autonomic neuropathies, glomerulosclerosis of the kidneys (with proteinuria, nephrotic syndrome, or end-stage renal failure), coronary and peripheral vascular disease, and reduced resistance to infections. Patients with DM often also sustain infected ulcerations of the feet, which may result in osteomyelitis and the need for amputation.
Persons with diabetes are prone to infection, delayed healing, and vascular disease. The ease with which poorly controlled diabetic persons develop an infection is thought to be due in part to decreased chemotaxis of leukocytes, abnormal phagocyte function, and diminished blood supply because of atherosclerotic changes in the blood vessels. An impaired blood supply means a deficit in the protective defensive cells transported in the blood. Excessive glucose allows organisms to grow out of control.
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]

A second theory, dubbed the hygiene hypothesis, blames the rise of type 1 on a society that's too clean. Good housekeeping and hygiene habits mean far fewer interactions with germs, which in turn may foster an immune system prone to going awry. "In a developing country, you have more infectious disease. This is associated with a lower risk of type 1 diabetes," says Li Wen, MD, PhD, an immunologist at the Yale University School of Medicine. In her lab, rodents raised in hyper-clean environments are more likely to get type 1 than those reared in dirtier cages.
Glucose is vital to your health because it's an important source of energy for the cells that make up your muscles and tissues. It's also your brain's main source of fuel. If you have diabetes, no matter what type, it means you have too much glucose in your blood, although the causes may differ. Too much glucose can lead to serious health problems.
Visual impairment and blindness are common sequelae of uncontrolled diabetes. The three most frequently occurring problems involving the eye are diabetic retinopathy, cataracts, and glaucoma. photocoagulation of destructive lesions of the retina with laser beams can be used to delay further progress of pathologic changes and thereby preserve sight in the affected eye.
For people who want to avoid drugs, taking an aggressive approach to healthy eating plan and lifestyle change is an option. It isn't easy, but if someone is very committed and motivated, lifestyle changes can be enough to maintain a healthy blood sugar level and to lose weight. Learning about a healthy diabetes diet (a low glycemic load diet) can be an good place to start.
After eating carbohydrates, the carbs break down into sugar, trigger the pancreas to produce insulin and are then stored in liver and muscles. However, there is a limit to the amount of sugar the liver and muscles can store. The easiest way to understand this is to think of your liver and muscles as small closets without much storage space. If sugar keeps coming in, the closet will quickly fill up.

Symptoms of type 1 diabetes can start quickly, in a matter of weeks. Symptoms of type 2 diabetes often develop slowly—over the course of several years—and can be so mild that you might not even notice them. Many people with type 2 diabetes have no symptoms. Some people do not find out they have the disease until they have diabetes-related health problems, such as blurred vision or heart trouble.
A 2018 study suggested that three types should be abandoned as too simplistic.[57] It classified diabetes into five subgroups, with what is typically described as type 1 and autoimmune late-onset diabetes categorized as one group, whereas type 2 encompasses four categories. This is hoped to improve diabetes treatment by tailoring it more specifically to the subgroups.[58]
Considering that being overweight is a risk factor for diabetes, it sounds counterintuitive that shedding pounds could be one of the silent symptoms of diabetes. “Weight loss comes from two things,” says Dr. Cypess. “One, from the water that you lose [from urinating]. Two, you lose some calories in the urine and you don’t absorb all the calories from the sugar in your blood.” Once people learn they have diabetes and start controlling their blood sugar, they may even experience some weight gain—but “that’s a good thing,” says Dr. Cypess, because it means your blood sugar levels are more balanced.

Sugar doesn't cause diabetes. But there is one way that sugar can influence whether a person gets type 2 diabetes. Consuming too much sugar (or sugary foods and drinks) can make people put on weight. Gaining too much weight leads to type 2 diabetes in some people. Of course, eating too much sugar isn't the only cause of weight gain. Weight gain from eating too much of any food can make a person's chance of getting diabetes greater.

All you need to know about insulin sensitivity factor Insulin sensitivity factor is a measurement that describes how blood sugar levels are affected by taking 1 unit of insulin. It can help a person with type 1 diabetes regulate their blood sugar levels. Learn more about what insulin sensitivity factor is, who should test and when, and what the results mean. Read now
Accelerated atherosclerosis is the main underlying factor contributing to the high risk of atherothrombotic events in DM patients. CAD, peripheral vascular disease, stroke, and increased intima-media thickness are the main macrovascular complications. Diabetics are 2–4 times more likely to develop stroke than people without DM.2 CVD, particularly CAD, is the leading cause of morbidity and mortality in patients with DM.4 Patients with T2DM have a 2- to 4-fold increase in the risk of CAD, and patients with DM but without previous myocardial infarction (MI) carry the same level of risk for subsequent acute coronary events as nondiabetic patients with previous MI.5 Furthermore, people with diabetes have a poorer long-term prognosis after MI, including an increased risk for congestive heart failure and death.

The WHO estimates that diabetes mellitus resulted in 1.5 million deaths in 2012, making it the 8th leading cause of death.[9][101] However another 2.2 million deaths worldwide were attributable to high blood glucose and the increased risks of cardiovascular disease and other associated complications (e.g. kidney failure), which often lead to premature death and are often listed as the underlying cause on death certificates rather than diabetes.[101][104] For example, in 2014, the International Diabetes Federation (IDF) estimated that diabetes resulted in 4.9 million deaths worldwide,[19] using modeling to estimate the total number of deaths that could be directly or indirectly attributed to diabetes.[20]
Triglycerides are a common form of fat that we digest. Triglycerides are the main ingredient in animal fats and vegetable oils. Elevated levels of triglycerides are a risk factor for heart disease, heart attack, stroke, fatty liver disease, and pancreatitis. Elevated levels of triglycerides are also associated with diseases like diabetes, kidney disease, and medications (for example, diuretics, birth control pills, and beta blockers). Dietary changes, and medication if necessary can help lower triglyceride blood levels.
When diabetes occurs in women during pregnancy, it is called gestational diabetes. It usually is diagnosed between the 24th and 28th weeks of pregnancy. Like in type 1 and type 2 diabetes, blood sugar levels become too high. When women are pregnant, more glucose is needed to nourish the developing baby. The body needs more insulin, which is produced by the pancreas. In some women, the body does not produce enough insulin to meet this need, and blood sugar levels rise, resulting in gestational diabetes.
Family or personal history. Your risk increases if you have prediabetes — a precursor to type 2 diabetes — or if a close family member, such as a parent or sibling, has type 2 diabetes. You're also at greater risk if you had gestational diabetes during a previous pregnancy, if you delivered a very large baby or if you had an unexplained stillbirth.
