People who are obese -- more than 20% over their ideal body weight for their height -- are at particularly high risk of developing type 2 diabetes and its related medical problems. Obese people have insulin resistance. With insulin resistance, the pancreas has to work overly hard to produce more insulin. But even then, there is not enough insulin to keep sugars normal.
Don’t be alarmed: This is not diabetic retinopathy, where the blood vessels in the back of the eye are getting destroyed, says Dr. Cypess. In the early stages of diabetes, the eye lens is not focusing well because glucose builds up in the eye, which temporarily changes its shape. “You’re not going blind from diabetes,” Dr. Cypess says he assures patients. “In about six to eight weeks after your blood sugars are stabilized, you’re not going to feel it anymore; the eye will adjust.” Here are more surprising facts you never knew about diabetes.
Hypoglycemia. Hypoglycemia or “insulin shock” is a common concern in DM management. It typically develops when a diabetic patient takes his or her normal dose of insulin without eating normally. As a result, the administered insulin can push the blood sugar to potentially dangerously low levels. Initially the patient may experience, sweating, nervousness, hunger and weakness. If the hypoglycemic patient is not promptly given sugar (sugar, cola, cake icing), he or she may lose consciousness and even lapse into coma. Questions and Answers about Diabetes and Your Mouth Q: If I have diabetes, will I develop the oral complications that were mentioned? A: It depends. There is a two-way relationship between your oral health and how well your blood sugar is controlled (glycemic control). Poor control of your blood sugar increases your risk of developing the multitude of complications associated with diabetes, including oral complications. Conversely, poor oral health interferes with proper glucose stabilization. Indeed, recent research has shown that diabetic patients who improve their oral health experience a modest improvement in their blood sugar levels. In essence, “Healthy mouths mean healthy bodies.” Q: What are the complications of diabetes therapy that can impact my oral health? A: One of the most worrisome urgent complications associated with diabetes management is the previously described hypoglycemia or insulin shock. In addition, many of the medications prescribed to treat diabetes and its complications, such as hypertension and heart disease, may induce adverse side effects affecting the mouth. Common side effects include dry mouth, taste aberrations, and mouth sores. Q: I have type-2 diabetes. Are my dental problems different than those experienced by people with type-1 diabetes? A: No. All patients with diabetes are at increased risk for the development of dental disease. What is different is that type-2 disease tends to progress more slowly than type-1 disease. Thus, most type-2 diabetes patients are diagnosed later in life, a time in which they are likely to already have existing dental problems. Remember, there is no dental disease unique to diabetes. Uncontrolled or poorly controlled diabetes simply compromises your body’s ability to control the existing disease.
Treatment of high blood pressure and high cholesterol levels, which can contribute to circulation problems, can help prevent some of the complications of diabetes as well. A low dose of aspirin taken daily is recommended in people with risk factors for heart disease. All people with diabetes who are between 40 and 75 years are given a statin (a drug to decrease cholesterol levels) regardless of cholesterol levels. Younger people with an elevated risk of heart disease should also take a statin .
Prediabetes is a condition in which blood glucose levels are too high to be considered normal but not high enough to be labeled diabetes. People have prediabetes if their fasting blood glucose level is between 100 mg/dL and 125 mg/dL or if their blood glucose level 2 hours after a glucose tolerance test is between 140 mg/dL and 199 mg/dL. Prediabetes carries a higher risk of future diabetes as well as heart disease. Decreasing body weight by 5 to 10% through diet and exercise can significantly reduce the risk of developing future diabetes.
Diabetes mellitus, or as it's more commonly known diabetes, is a disease characterized by an excess of blood glucose, or blood sugar, which builds up in the bloodstream when your body isn't able to adequately process the sugar in food. High blood sugar is an abnormal state for the body and creates specific symptoms and possible long-term health problems if blood sugar is not managed well.
Insulin treatment can cause weight gain and low blood sugar. In addition, there may be discomfort at the injection site. There are several types of tablets used to treat diabetes and they have different side-effects. The most common are diarrhoea (metformin), nausea (GLP-1 agoniists), weight-gain (sulphonylureas and pioglitazone), low blood sugar (sulphonylureas) and genital thrush (SGLT2 inhibitors). However, not all patients will experience some or any of these side-effects and patients should discuss any concerns with their doctor.

Skin care: High blood glucose and poor circulation can lead to skin problems such as slow healing after an injury or frequent infections. Make sure to wash every day with a mild soap and warm water, protect your skin by using sunscreen, take good care of any cuts or scrapes with proper cleansing and bandaging, and see your doctor when cuts heal slowly or if an infection develops.
Other studies have focused, not on sugar overall but specifically on sodas and other sugar-sweetened beverages. Many have found no significant relationship, apart from sugar’s extra calories that lead to weight gain. For example, the Women’s Health Study,8 the Atherosclerosis Risk in Communities Study,9 the Black Women’s Health Study,10 and the Multi-Ethnic Study of Atherosclerosis found no significant associations between sugar consumption and diabetes risk after adjustment for measures of body weight. Some studies have had mixed results, exonerating sucrose, but indicting glucose and fructose.12,13 And some studies have shown associations between sugar-sweetened beverages and diabetes that persist after adjustment for body weight.14,15
Treatment of pituitary diabetes insipidus consists of administration of vasopressin. A synthetic analogue of vasopressin (DDAVP) can be administered as a nasal spray, providing antidiuretic activity for 8 to 20 hours, and is currently the drug of choice. Patient care includes instruction in self-administration of the drug, its expected action, symptoms that indicate a need to adjust the dosage, and the importance of follow-up visits. Patients with this condition should wear some form of medical identification at all times.
Diabetic retinopathy is a leading cause of blindness and visual disability. Diabetes mellitus is associated with damage to the small blood vessels in the retina, resulting in loss of vision. Findings, consistent from study to study, make it possible to suggest that, after 15 years of diabetes, approximately 2% of people become blind, while about 10% develop severe visual handicap. Loss of vision due to certain types of glaucoma and cataract may also be more common in people with diabetes than in those without the disease.
Every cell in the human body needs energy in order to function. The body's primary energy source is glucose, a simple sugar resulting from the digestion of foods containing carbohydrates (sugars and starches). Glucose from the digested food circulates in the blood as a ready energy source for any cells that need it. Insulin is a hormone or chemical produced by cells in the pancreas, an organ located behind the stomach. Insulin bonds to a receptor site on the outside of cell and acts like a key to open a doorway into the cell through which glucose can enter. Some of the glucose can be converted to concentrated energy sources like glycogen or fatty acids and saved for later use. When there is not enough insulin produced or when the doorway no longer recognizes the insulin key, glucose stays in the blood rather entering the cells.
Is it your fault for getting type 2 diabetes? No – type 2 diabetes is not a personal failing. It develops through a combination of factors that are still being uncovered and better understood. Lifestyle (food, exercise, stress, sleep) certainly plays a major role, but genetics play a significant role as well. Type 2 diabetes is often described in the media as a result of being overweight, but the relationship is not that simple. Many overweight individuals never get type 2, and some people with type 2 were never overweight, (although obesity is probably an underlying cause of insulin resistance). To make matters worse, when someone gains weight (for whatever reason), the body makes it extremely difficult to lose the new weight and keep it off. If it were just a matter of choice or a bit of willpower, we would probably all be skinny. At its core, type 2 involves two physiological issues: resistance to the insulin made by the person’s beta cells and too little insulin production relative to the amount one needs.
Diabetes mellitus is not a single disorder but a heterogeneous group of disorders. All forms are characterized by hyperglycemia and disturbances of carbohydrate, fat, and protein metabolism which are associated with absolute or relative deficiencies of insulin action and/or insulin secretion. The World Health Organization (WHO) developed a now widely accepted classification of the disorder, largely based on clinical characteristics (see Table 1, WHO, 1985).
Type 2 diabetes, which is often diagnosed when a person has an A1C of at least 7 on two separate occasions, can lead to potentially serious issues, like neuropathy, or nerve damage; vision problems; an increased risk of heart disease; and other diabetes complications. A person’s A1C is the two- to three-month average of his or her blood sugar levels.
