Schedule a yearly physical exam and regular eye exams. Your regular diabetes checkups aren't meant to replace regular physicals or routine eye exams. During the physical, your doctor will look for any diabetes-related complications, as well as screen for other medical problems. Your eye care specialist will check for signs of retinal damage, cataracts and glaucoma.
But preventing the disease from progressing if you already have it requires first being able to spot the signs and symptoms of diabetes when they appear. While some type 2 diabetes symptoms may not ever show up, you can watch out for the following common signs of the disease and alert your doctor, especially if you have any of the common risk factors for diabetes. Also keep in mind that while most signs of type 2 diabetes are the same in men and women, there are some distinctions.
Keep your immunizations up to date. High blood sugar can weaken your immune system. Get a flu shot every year, and your doctor will likely recommend the pneumonia vaccine, as well. The Centers for Disease Control and Prevention (CDC) also recommends the hepatitis B vaccination if you haven't previously received this vaccine and you're an adult age 19 to 59 with type 1 or type 2 diabetes. The CDC advises vaccination as soon as possible after diagnosis with type 1 or type 2 diabetes. If you are age 60 or older, have diabetes and haven't previously received the vaccine, talk to your doctor about whether it's right for you.
Diet management is very important in people with both types of diabetes mellitus. Doctors recommend a healthy, balanced diet and efforts to maintain a healthy weight. People with diabetes can benefit from meeting with a dietitian or a diabetes educator to develop an optimal eating plan. Such a plan includes avoiding simple sugars and processed foods, increasing dietary fiber, limiting portions of carbohydrate-rich, and fatty foods (especially saturated fats). People who are taking insulin should avoid long periods between meals to prevent hypoglycemia. Although protein and fat in the diet contribute to the number of calories a person eats, only the number of carbohydrates has a direct effect on blood glucose levels. The American Diabetes Association has many helpful tips on diet, including recipes. Even when people follow a proper diet, cholesterol-lowering drugs are needed to decrease the risk of heart disease (see recommendations).
Awareness about the signs and symptoms and periodic screening especially in the presence of risk factors and warning signs of diabetes, would go a long way in preventing new cases of diabetes by providing an opportunity to intervene at the stage of prediabetes. It is evident that diabetes can be prevented among prediabetic individuals by improvements in physical activity and diet habits. Such strategies will also prevent development of diabetic complications to a great extent. Patient empowerment is vital in diabetes management. This can be done through patient education and sharing information on management and preventive aspects of diabetes.
Fasting glucose test This test involves giving a blood sample after you have fasted for eight hours. (18) If you have a fasting blood sugar level of less than 100 milligrams per deciliter (mg/dl), your blood sugar levels are normal. But if you have one from 100 to 125 mg/dl, you have prediabetes, and if you have 126 mg/dl on two separate occasions, you have diabetes. (17)
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.
It is important to record blood glucose readings taken at different times of the day – after fasting (before breakfast) as well as 2 hours after a meal. This allows your doctor to see a snapshot of how your blood glucose levels vary during the day and to recommend treatments accordingly. Most blood glucose meters now have "memory" that stores a number of blood glucose tests along with the time and date they were taken. Some even allow for graphs and charts of the results to be created and sent to your phone.
Diabetes mellitus (DM) is best defined as a syndrome characterized by inappropriate fasting or postprandial hyperglycemia, caused by absolute or relative insulin deficiency and its metabolic consequences, which include disturbed metabolism of protein and fat. This syndrome results from a combination of deficiency of insulin secretion and its action. Diabetes mellitus occurs when the normal constant of the product of insulin secretion times insulin sensitivity, a parabolic function termed the “disposition index” (Figure 19-1), is inadequate to prevent hyperglycemia and its clinical consequences of polyuria, polydipsia, and weight loss. At high degrees of insulin sensitivity, small declines in the ability to secrete insulin cause only mild, clinically imperceptible defects in glucose metabolism. However, irrespective of insulin sensitivity, a minimum amount of insulin is necessary for normal metabolism. Thus, near absolute deficiency of insulin must result in severe metabolic disturbance as occurs in type 1 diabetes mellitus (T1DM). By contrast, with decreasing sensitivity to its action, higher amounts of insulin secretion are required for a normal disposition index. At a critical point in the disposition index curve (see Figure 19-1), a further small decrement in insulin sensitivity requires a large increase in insulin secretion; those who can mount these higher rates of insulin secretion retain normal glucose metabolism, whereas those who cannot increase their insulin secretion because of genetic or acquired defects now manifest clinical diabetes as occurs in type 2 diabetes (T2DM).
WELL-CONTROLLED DIABETES MELLITUS: Daily blood sugar abstracted from the records of a patient whose DM is well controlled (hemoglobin A1c=6.4). The average capillary blood glucose level is 104 mg/dL, and the standard deviation is 19. Sixty-five percent of the readings are between 90 and 140 mg/dL; the lowest blood sugar is 67 mg/dL (on April 15) and the highest is about 190 (on March 21).
For example, the environmental trigger may be a virus or chemical toxin that upsets the normal function of the immune system. This may lead to the body’s immune system attacking itself. The normal beta cells in the pancreas may be attacked and destroyed. When approximately 90% of the beta cells are destroyed, symptoms of diabetes mellitus begin to appear. The exact cause and sequence is not fully understood but investigation and research into the disease continues.
Insulin Therapy. Exogenous insulin is given to patients with diabetes mellitus as a supplement to the insufficient amount of endogenous insulin that they produce. In some cases, this must make up for an absolute lack of insulin from the pancreas. Exogenous insulin is available in various types. It must be given by injection, usually subcutaneously, and because it is a potent drug, the dosage must be measured meticulously. Commonly, regular insulin, which is a fast-acting insulin with a short span of action, is mixed with one of the longer-acting insulins and both types are administered in one injection.
Regular ophthalmological examinations are recommended for early detection of diabetic retinopathy. The patient is educated about diabetes, its possible complications and their management, and the importance of adherence to the prescribed therapy. The patient is taught the importance of maintaining normal blood pressure levels (120/80 mm Hg or lower). Control of even mild-to-moderate hypertension results in fewer diabetic complications, esp. nephropathy, cerebrovascular disease, and cardiovascular disease. Limiting alcohol intake to approximately one drink daily and avoiding tobacco are also important for self-management. Emotional support and a realistic assessment of the patient's condition are offered; this assessment should stress that, with proper treatment, the patient can have a near-normal lifestyle and life expectancy. Long-term goals for a patient with diabetes should include achieving and maintaining optimal metabolic outcomes to prevent complications; modifying diet and lifestyle to prevent and treat obesity, dyslipidemia, cardiovascular disease, hypertension, and nephropathy; improving physical activity; and allowing for the patient’s nutritional and psychosocial needs and preferences. Assistance is offered to help the patient develop positive coping strategies. It is estimated that 23 million Americans will be diabetic by the year 2030. The increasing prevalence of obesity coincides with the increasing incidence of diabetes; approx. 45% of those diagnosed receive optimal care according to established guidelines. According to the CDC, the NIH, and the ADA, about 40% of Americans between ages 40 and 74 have prediabetes, putting them at increased risk for type 2 diabetes and cardiovascular disease. Lifestyle changes with a focus on decreasing obesity can prevent or delay the onset of diabetes in 58% of this population. The patient and family should be referred to local and national support and information groups and may require psychological counseling.
There are many types of sugar. Some sugars are simple, and others are complex. Table sugar (sucrose) is made of two simpler sugars called glucose and fructose. Milk sugar (lactose) is made of glucose and a simple sugar called galactose. The carbohydrates in starches, such as bread, pasta, rice, and similar foods, are long chains of different simple sugar molecules. Sucrose, lactose, carbohydrates, and other complex sugars must be broken down into simple sugars by enzymes in the digestive tract before the body can absorb them.
What medication is available for diabetes? Diabetes causes blood sugar levels to rise. The body may stop producing insulin, the hormone that regulates blood sugar, and this results in type 1 diabetes. In people with type 2 diabetes, insulin is not working effectively. Learn about the range of treatments for each type and recent medical developments here. Read now
Type 2 DM is characterized by insulin resistance, which may be combined with relatively reduced insulin secretion. 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.
The typical symptoms of diabetes mellitus are the three “polys:” polyuria, polydipsia, and polyphagia. Because of insulin deficiency, the assimilation and storage of glucose in muscle adipose tissues, and the liver is greatly diminished. This produces an accumulation of glucose in the blood and creates an increase in its osmolarity. In response to this increased osmotic pressure there is depletion of intracellular water and osmotic diuresis. The water loss creates intense thirst and increased urination. The increased appetite (polyphagia) is not as clearly understood. It may be the result of the body's effort to increase its supply of energy foods even though eating more carbohydrates in the absence of sufficient insulin does not meet the energy needs of the cells.
Information on mortality rates for type 1 diabetes mellitus is difficult to ascertain without complete national registers of childhood diabetes, although age-specific mortality is probably double that of the general population. [35, 36] Children aged 1-4 years are particularly at risk and may die due to DKA at the time of diagnosis. Adolescents are also a high-risk group. Most deaths result from delayed diagnosis or neglected treatment and subsequent cerebral edema during treatment for DKA, although untreated hypoglycemia also causes some deaths. Unexplained death during sleep may also occur and appears more likely to affect young males. 
Unexplained weight loss can happen for lots of reasons, and diabetes is one of them. Goundan explains that insulin helps your body move sugar from your blood to your cells, so when you have an insulin resistance, you don’t get enough energy into your cells despite all that sugar flowing through your body. “Because you’re unable to get enough energy from sugar, your body burns your own fat and muscle for energy," Kellis says. "Weight loss can be pretty significant, sometimes 10 to 20 pounds."
There are two major types of diabetes, called type 1 and type 2. Type 1 diabetes was also formerly called insulin dependent diabetes mellitus (IDDM), or juvenile-onset diabetes mellitus. In type 1 diabetes, the pancreas undergoes an autoimmune attack by the body itself, and is rendered incapable of making insulin. Abnormal antibodies have been found in the majority of patients with type 1 diabetes. Antibodies are proteins in the blood that are part of the body's immune system. The patient with type 1 diabetes must rely on insulin medication for survival.
It has become fashionable in recent years to blame sugar for many health problems. However, per capita sugar consumption has actually been falling in the United States since 1999, when bottled water and sugar-free beverages began to edge sodas off the shelf. At the same time, consumption of cheese and oily foods has steadily increased, as has diabetes prevalence. This suggests that something other than sugar is driving the diabetes epidemic.
But if you’re struggling with weight loss, eating fewer foods with added sugar and fat can be a step in the right direction for improving your health and potentially reducing your diabetes risk. In fact, if you have been diagnosed with prediabetes, losing just 5 to 7 percent of your body weight can reduce your risk for type 2 diabetes, according to the CDC.
Given the diverse peculiarities involving the issue, studies have shown that Diabetes mellitus has been extensively investigated in its pathophysiological aspects, highlighting the search for strong evidence that can be used in the clinical practice of the Primary Care nurse, with attributions focused on health promotion, prevention of complications, treatment and rehabilitation of the health of individuals and community, carried out in an interdisciplinary and multidisciplinary manner (Matumoto, Fortuna, Kawata, Mishima, & Pereira, 2011; Florianopolis, 2015).
Prevention and treatment involve maintaining a healthy diet, regular physical exercise, a normal body weight, and avoiding use of tobacco. Control of blood pressure and maintaining proper foot care are important for people with the disease. Type 1 DM must be managed with insulin injections. Type 2 DM may be treated with medications with or without insulin. Insulin and some oral medications can cause low blood sugar. Weight loss surgery in those with obesity is sometimes an effective measure in those with type 2 DM. Gestational diabetes usually resolves after the birth of the baby.
When the glucose concentration in the blood remains high over time, the kidneys will reach a threshold of reabsorption, and glucose will be excreted in the urine (glycosuria). This increases the osmotic pressure of the urine and inhibits reabsorption of water by the kidney, resulting in increased urine production (polyuria) and increased fluid loss. Lost blood volume will be replaced osmotically from water held in body cells and other body compartments, causing dehydration and increased thirst (polydipsia).
But the 2015-2020 Dietary Guidelines recommend keeping added sugar below 10 percent of your overall daily caloric intake. And the American Heart Association suggests consuming no more than 9 teaspoons (tsp) — equal to 36 grams (g) or 150 calories — of added sugar if you're a man, and 6 tsp — equal to 25 g or 100 calories — if you're a woman. "Naturally occurring sugars don't count in these recommendations," notes Grieger, which means you should worry less about those sugars in fruits and veggies, for instance, than you should about those in processed fare.
Beta cells are vulnerable to more than just bad genes, which may explain the associations between type 2 diabetes and environmental factors that aren't related to how much fat a body has or where it is stored. Beta cells carry vitamin D receptors on their surface, and people with vitamin D deficiency are at increased risk for type 2. Plus, several studies have shown that people with higher levels of toxic substances in their blood—such as from the PCBs found in fish fat—are at increased risk of type 2 diabetes, though a cause-and-effect relationship hasn't been proved. (Toxic substances and vitamin D have also been implicated in type 1 diabetes, but the disease mechanism may be unrelated to what's going on in type 2.)
As part of proper diabetes management, it is important to be aware of the symptoms of abnormal blood glucose levels and know how to properly monitor your blood glucose levels using a home glucose meter. You should remember to always keep glucose tablets or candies containing sugar with you at all times to manage low blood glucose levels (hypoglycemia). Symptoms of low blood glucose include:
A fingerstick glucose test is most often used to monitor blood glucose. Most blood glucose monitoring devices (glucose meters) use a drop of blood obtained by pricking the tip of the finger with a small lancet. The lancet holds a tiny needle that can be jabbed into the finger or placed in a spring-loaded device that easily and quickly pierces the skin. Most people find that the pricking causes only minimal discomfort. Then, a drop of blood is placed on a reagent strip. The strip contains chemicals that undergo changes depending on the glucose level. The glucose meter reads the changes in the test strip and reports the result on a digital display. Some devices allow the blood sample to be obtained from other sites, such as the palm, forearm, upper arm, thigh, or calf. Home glucose meters are smaller than a deck of cards.
Diabetes mellitus (DM) is a strong predictor of cardiovascular morbidity and mortality and is associated with both micro- and macrovascular complications.1 Cardiovascular disease (CVD) causes up to 70% of all deaths in people with DM. The epidemic of DM will thus be followed by a burden of diabetes-related vascular diseases. The number of DM patients increases with aging of the population, in part because of the increasing prevalence of obesity and sedentary lifestyle. Although the mortality from coronary artery disease (CAD) in patients without DM has declined since the 1990s, the mortality in men with type 2 diabetes (T2DM) has not changed significantly.2 Moreover, DM is an independent risk factor for heart failure. Heart failure is closely related to diabetic cardiomyopathy: changes in the structure and function of the myocardium are not directly linked to CAD or hypertension. Diabetic cardiomyopathy is clinically characterized by an initial increase in left ventricular stiffness and subclinical diastolic dysfunction, gradually compromising left ventricular systolic function with loss of contractile function and progress into overt congestive heart failure. DM accounts for a significant percentage of patients with a diagnosis of heart failure in epidemiologic studies such as the Framingham Study and the UK Prospective Diabetes Study (UKPDS).2 A 1% increase in glycated hemoglobin (HbA1c) correlates to an increment of 8% in heart failure.3 The prevalence of heart failure in elderly diabetic patients is up to 30%.3
The elderly diabetic person is at increased risk of atrial fibrillation (odds ratio: 1.4 for men and 1.6 for women)232 and at twofold increased risk of thromboembolism from atrial fibrillation.233,234 We can find no subgroup analysis of the major atrial fibrillation trials to examine the benefits of warfarin specifically in older diabetic subjects. It appears that the adverse event rate in diabetic people drops from 8.6 events per 100 patients per year to 2.8 events with warfarin use.234 It is important to check for retinal new vessels when diabetic subjects are placed on warfarin, although the Early Treatment Diabetic Retinopathy Study235 showed no excess vitreous or preretinal hemorrhages in subjects given aspirin for vascular prophylaxis.
Yes. In fact, being sick can actually make the body need more diabetes medicine. If you take insulin, you might have to adjust your dose when you're sick, but you still need to take insulin. People with type 2 diabetes may need to adjust their diabetes medicines when they are sick. Talk to your diabetes health care team to be sure you know what to do.
You have a higher risk of type 2 diabetes if you are older, have obesity, have a family history of diabetes, or do not exercise. Having prediabetes also increases your risk. Prediabetes means that your blood sugar is higher than normal but not high enough to be called diabetes. If you are at risk for type 2 diabetes, you may be able to delay or prevent developing it by making some lifestyle changes.
Diabetes means your blood glucose, or blood sugar, levels are too high. With type 2 diabetes, the more common type, your body does not make or use insulin well. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth.
Apart from severe DKA or hypoglycemia, type 1 diabetes mellitus has little immediate morbidity. The risk of complications relates to diabetic control. With good management, patients can expect to lead full, normal, and healthy lives. Nevertheless, the average life expectancy of a child diagnosed with type 1 diabetes mellitus has been variously suggested to be reduced by 13-19 years, compared with their nondiabetic peers. 
Diabetes mellitus is a chronic disease for which there is treatment but no known cure. Treatment is aimed at keeping blood glucose levels as close to normal as possible. This is achieved with a combination of diet, exercise and insulin or oral medication. People with type 1 diabetes need to be hospitalized right after they are diagnosed to get their glucose levels down to an acceptable level.
Before blood glucose levels rise, the body of a person destined for type 2 becomes resistant to insulin, much as bacteria can become resistant to antibiotics. Insulin is the signal for the muscles, fat, and liver to absorb glucose from the blood. As the body becomes resistant to insulin, the beta cells in the pancreas must pump out more of the hormone to compensate. People with beta cells that can't keep up with insulin resistance develop the high blood glucose of type 2 diabetes.
Type 2 (formerly called 'adult-onset' or 'non insulin-dependent') diabetes results when the body doesn’t produce enough insulin and/or is unable to use insulin properly (this is also referred to as ‘insulin resistance’). This form of diabetes usually occurs in people who are over 40 years of age, overweight, and have a family history of diabetes, although today it is increasingly found in younger people.
Adult and pediatric endocrinologists, specialists in treating hormone imbalances and disorders of the endocrine system, are experts in helping patients with diabetes manage their disease. People with the disease also may be cared for by a number of primary care providers including family or internal medicine practitioners, naturopathic doctors, or nurse practitioners. When complications arise, these patients often consult other specialists, including neurologists, gastroenterologists, ophthalmologists, acupuncturists, surgeons, and cardiologists. Nutritionists, integrative and functional medicine doctors, and physical activity experts such as personal trainers are also important members of a diabetes treatment team. It is important to interview a new health care professional about their experience, expertise, and credentials to make sure they are well qualified to help you.
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.
One of the most common ways people with type 2 diabetes attempt to lower their blood sugar is by drastically reducing their intake of carbs. The ADA agrees that carbohydrate counting is essential if you have diabetes, but extreme diets like the ketogenic diet, which reduces carb intake to as little as 5 percent of your daily calories, can be risky for some people with diabetes. (36)
Type 2 diabetes is a preventable disease that affects more than 9 percent of the U.S. population, or about 29 million people. According to the Centers for Disease Control and Prevention, more than a quarter — some 8 million people — remain undiagnosed. With complications including nerve damage, kidney damage, poor blood circulation, and even death, it’s important for us all to know the early signs of type 2 diabetes.
