CHAPTER I
INTRODUCE
A.    BACKGROUND
A worldwide epidemic of diabetes mellitus is looming. The Centers for Disease Control and Prevention (CDC) predicts the national incidence of diabetes will rise by 37.5% by the year 2025 and by 170% in developing countries over the next 30 years. Of particular concern is the alarming increase in the prevalence of type 2 diabetes in both adults and children. In 2002, an estimated 18.2 million people, or 6.3% of the United States population, had diabetes. Of these, 5.2 million or about one-third were undiagnosed. But there is good news. Clinical studies have affirmed that type 2 diabetes can be delayed or prevented in high-risk populations and that good glycemic control and other interventions can slow the devastating complications of diabetes. Nevertheless, broad implementation of guidelines and goals established by the American Diabetes Association and others has been slow.
From the above background writer interested in discussing about the “Perfect guide to Understanding Diabetis”.

CHAPTER II
DISCUSSION

A.    What is diabetes?
        The term "diabetes mellitus" describes a metabolic disorder of multiple aetiology characterized by chronic hyperglycaemia with disturbances of carbohydrate, fat and protein metabolism resulting from defects in insulin secretion, insulin action, or both. The effects of diabetes mellitus include long–term damage, dysfunction and failure of various organs (WHO 1999).
        Diabetes is a chronic disease that occurs when the pancreas does not produce enough insulin, or when the body cannot effectively use the insulin it produces. Hyperglycaemia, or raised blood sugar, is a common effect of uncontrolled diabetes and over time leads to serious damage to many of the body's systems, especially the nerves and blood vessels.

B.     There are two main types of diabetes

Type 1 diabetes (T1D)

Description

·         formerly known as Insulin-Dependent Diabetes Mellitus (IDDM).
·         characterized by hyperglycemia due to an absolute deficiency of the insulin hormone produced by the pancreas.
·         patients require lifelong insulin injections for survival.
·         usually develops in children and adolescents (although can occur later in life).
·         may present with severe symptoms such as coma or ketoacidosis.
·         patients are usually not obese with this type of diabetes, but obesity is not incompatible with the diagnosis.
·         patients are at increased risk of developing microvascular and macrovascular complications.

Symptoms

·         increased urinary frequency (polyuria), thirst (polydipsia), hunger (polyphagia), and unexplained weight loss.
·         numbness in extremities, pain in feet (disesthesias), fatigue, and blurred vision.
·         recurrent or severe infections.
·         loss of consciousness or severe nausea/vomiting (ketoacidosis) or coma. Ketoacidosis more common in T1D than in T2D.

Type 2 diabetes T2D

Description

·         formerly named non-insulin-dependent diabetes mellitus (NIDDM).
·         characterized by hyperglycemia due to a defect in insulin secretion usually with a contribution from insulin resistance.
·         patients usually do not require lifelong insulin but can control blood glucose with diet and exercise alone, or in combination with oral medications, or with the addition of insulin.
·         usually (but not always) develops in adulthood (and is on the rise in children and adolescents).
·         is related to obesity, decreased physical activity and unhealthy diets.
·         as in T1D, patients are at a higher risk of microvascular and macrovascular complications.

Symptoms

·         patients may have no symptoms at all or minimal symptoms for years before being diagnosed.
·         may have increased urinary frequency (polyuria), thirst (polydipsia), hunger (polyphagia), and unexplained weight loss.
·         may also experience numbness in extremities, pain in feet (disesthesias), and blurred vision.
·         may have recurrent or severe infections.
·         patients may present with loss of consciousness or coma but this is less common than in T1D.

Gestational diabetes (GDM)

Description

·         characterized by hyperglycemia of varying severity diagnosed during pregnancy (without previously known diabetes) and usually (but not always) resolving within 6 weeks of delivery.
·         risks to the pregnancy itself include congenital malformations, increased birth weight and an elevated risk of perinatal mortality.
·         increased risk to woman of developing diabetes (T2D) later in life.

Symptoms

·         increased thirst (polydipsia) and increased urination (polyuria) are more commonly noted (although other symptoms can be present).
·         because pregnancy itself causes increased urination, these symptoms are difficult to recognize as abnormal.
·         a larger than normal baby during pregnancy (noted on routine prenatal exam) may prompt diabetic screening.
C.    How does to transmit diabetes ?

a.      Type 1, or juvenile diabetes, appears in very early childhood and is a chronic condition requiring drug therapy. It results from a failure of the autoimmune system that limits the ability of the pancreas to produce insulin. It cannot be "caught" like a virus or bacteria. However, recent studies have confirmed that certain DNA triggers tend to be present in persons with diabetes. When mothers with diabetes have obese children, the children often appear to inherit the same DNA characteristic and develop diabetes. Children who have two parents with diabetes also appear to inherit the characteristic. This tendency to inherit has only been established with Type 1 diabetes. Since a Type 1 diabetic's pancreas will never produce insulin properly, it is important to diagnose and begin a treatment plan as early in life as possible.
b.      Type 2 diabetes develops after age 40 in persons who have certain risk factors, including obesity, a carbohydrate-rich diet and sedentary lifestyle. Adult-onset diabetes limits the ability of insulin to control blood glucose levels, rather than attacking the pancreas directly. No genetic triggers have been identified. Gestational diabetes, a temporary condition that resembles---and may develop into---Type 2 diabetes, primarily affects pregnant women who are obese or who may gain a great deal of weight with pregnancy. Both conditions can usually be managed using careful control of diet, exercise and use of appropriate medication supervised by a medical professional. Although obesity may be related to hereditary metabolic factors, these types of diabetes seem to be more related to behavior and environment than to heredity. Behavioral factors, like diet and exercise seem to be more important than obesity alone. The type of diet people grow up eating may be a risk factor over which they have little control. Others, like sweets, junk food and a sedentary lifestyle can be controlled by using good nutritional practice and regular exercise. Medications are available to aid insulin in its task of blood sugar management, but insulin is seldom required if the adult-onset diabetic is willing to lose weight, modify diet and exercise regularly.

D.    Tasted and diagnosis diabetic
Symptoms of type 1 diabetes often appear suddenly and are often the reason for checking blood sugar levels. Because symptoms of other types of diabetes and prediabetes come on more gradually or may not be evident, the American Diabetes Association (ADA) has recommended screening guidelines. The ADA recommends that the following people be screened for diabetes:
·         Anyone with a body mass index higher than 25, regardless of age, who has additional risk factors, such as high blood pressure, a sedentary lifestyle, a history of polycystic ovary syndrome, having delivered a baby who weighed more than 9 pounds, a history of diabetes in pregnancy, high cholesterol levels, a history of heart disease, and having a close relative with diabetes.
·         Anyone older than age 45 is advised to receive an initial blood sugar screening, and then, if the results are normal, to be screened every three years thereafter.

E.     Tests for type 1 and type 2 diabetes

·         Glycated hemoglobin (A1C) test.
This blood test indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level of 6.5 percent or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 percent indicates prediabetes. Below 5.7 is considered normal.
·         Random blood sugar test. A blood sample will be taken at a random time. Regardless of when you last ate, a random blood sugar level of 200 milligrams per deciliter (mg/dL) — 11.1 millimoles per liter (mmol/L) — or higher suggests diabetes.
·         Fasting blood sugar test. A blood sample will be taken after an overnight fast. A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes.
·         Oral glucose tolerance test. For this test, you fast overnight, and the fasting blood sugar level is measured. Then you drink a sugary liquid, and blood sugar levels are tested periodically for the next two hours. A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours indicates diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) indicates prediabetes.

Tests for gestational diabetes

Your doctor will likely evaluate your risk factors for gestational diabetes early in your pregnancy:
·         If you're at high risk of gestational diabetes — for example, if you were obese at the start of your pregnancy, you had gestational diabetes during a previous pregnancy, or you have a mother, father, sibling or child with diabetes — your doctor may test for diabetes at your first prenatal visit.
    • If you're at average risk of gestational diabetes, you'll likely have a screening test for gestational diabetes sometime during your second trimester — typically between 24 and 28 weeks of pregnancy.
Your doctor may use the following screening tests:
·         Initial glucose challenge test.
You'll begin the glucose challenge test by drinking a syrupy glucose solution. One hour later, you'll have a blood test to measure your blood sugar level. A blood sugar level below 140 mg/dL (7.2 to 7.8 mmol/L) is usually considered normal on a glucose challenge test, although this may vary at specific clinics or labs. If your blood sugar level is higher than normal, it only means you have a higher risk of gestational diabetes. Your doctor will order a follow-up test to determine if you have gestational diabetes.

·         Follow-up glucose tolerance testing.
For the follow-up test, you'll be asked to fast overnight and then have your fasting blood sugar level measured. Then you'll drink another sweet solution — this one containing a higher concentration of glucose — and your blood sugar level will be checked every hour for a period of three hours. If at least two of the blood sugar readings are higher than the normal values established for each of the three hours of the test, you'll be diagnosed with gestational diabetes.

F.      Simple Steps to Lower Your Risk

Making a few lifestyle changes can dramatically lower the chances of developing type 2 diabetes. The same changes can also lower the chances of developing heart disease and some cancers.

Control Your Weight

Excess weight is the single most important cause of type 2 diabetes. Being overweight increases the chances of developing type 2 diabetes seven fold. Being obese makes you 20 to 40 times more likely to develop diabetes than someone with a healthy weight.
Losing weight can help if your weight is above the healthy-weight range. Losing 7 to 10 percent of your current weight can cut your chances of developing type 2 diabetes in half.

Get Moving—and Turn Off the Television

Inactivity promotes type 2 diabetes.Working your muscles more often and making them work harder improves their ability to use insulin and absorb glucose. This puts less stress on your insulin-making cells.
Long bouts of hot, sweaty exercise aren’t necessary to reap this benefit. Findings from the Nurses’ Health Study and Health Professionals Follow-up Study suggest that walking briskly for a half hour every day reduces the risk of developing type 2 diabetes by 30 percent.More recently, The Black Women’s Health Study reported similar diabetes-prevention benefits for brisk walking of more than 5 hours per week. This amount of exercise has a variety of other benefits as well. And even greater cardiovascular and other advantages can be attained by more, and more intense, exercise.
Television-watching appears to be an especially-detrimental form of inactivity: Every two hours you spend watching TV instead of pursuing something more active increases the chances of developing diabetes by 20 percent; it also increases the risk of heart disease (15 percent) and early death (13 percent).  The more television people watch, the more likely they are to be overweight or obese, and this seems to explain part of the TV viewing-diabetes link. The unhealthy diet patterns associated with TV watching may also explain some of this relationship.

Tune Up Your Diet

Four dietary changes can have a big impact on the risk of type 2 diabetes.
1. Choose whole grains and whole grain products over highly processed carbohydrates          .
There is convincing evidence that diets rich in whole grains protect against diabetes, whereas diets rich in refined carbohydrates lead to increased risk.In the Nurses’ Health Studies I and II, for example, researchers looked at the whole grain consumption of more than 160,000 women whose health and dietary habits were followed for up to 18 years. Women who averaged two to three servings of whole grains a day were 30 percent less likely to have developed type 2 diabetes than those who rarely ate whole grains. When the researchers combined these results with those of several other large studies, they found that eating an extra 2 servings of whole grains a day decreased the risk of type 2 diabetes by 21 percent.
Whole grains don’t contain a magical nutrient that fights diabetes and improves health. It’s the entire package—elements intact and working together—that’s important. The bran and fiber in whole grains make it more difficult for digestive enzymes to break down the starches into glucose. This leads to lower, slower increases in blood sugar and insulin, and a lower glycemic index. As a result, they stress the body’s insulin-making machinery less, and so may help prevent type 2 diabetes. Whole grains are also rich in essential vitamins, minerals, and phytochemicals that may help reduce the risk of diabetes.
In contrast, white bread, white rice, mashed potatoes, donuts, bagels, and many breakfast cereals have what’s called a high glycemic index and glycemic load. That means they cause sustained spikes in blood sugar and insulin levels, which in turn may lead to increased diabetes risk. In China, for example, where white rice is a staple, the Shanghai Women’s Health Study found that women whose diets had the highest glycemic index had a 21 percent higher risk of developing type 2 diabetes, compared to women whose diets had the lowest glycemic index. Similar findings were reported in the Black Women’s Health Study.
2. Skip the sugary drinks, and choose water, coffee, or tea instead.
Like refined grains, sugary beverages have a high glycemic load, and drinking more of this sugary stuff is associated with increased risk of diabetes. In the Nurses’ Health Study II, women who drank one or more sugar-sweetened beverages per day had an 83 percent higher risk of type 2 diabetes, compared to women who drank less than one sugar-sweetened beverage per month.
Combining the Nurses’ Health Study results with those from seven other studies found a similar link between sugary beverage consumption and type 2 diabetes: For every additional 12-ounce serving of sugary beverage that people drank each day, their risk of type 2 diabetes rose 25 percent.Studies also suggest that fruit drinks— Kool Aid, fortified fruit drinks, or juices—are not the healthy choice that food advertisements often portray them to be: Women in the Black Women’s Health study who drank two or more servings of fruit drinks a day had a 31 percent higher risk of type 2 diabetes, compared to women who drank less than one serving a month.
How do sugary drinks lead to this increased risk? Weight gain may explain the link: In both the Nurses’ Health Study II and the Black Women’s Health Study, women who increased their consumption of sugary drinks gained more weight than women who cut back on sugary drinks. Several studies show that children and adults who drink soda or other sugar-sweetened beverages are more likely to gain weight than those who don’t,and that switching from these to water or unsweetened beverages can reduce weight. Even so, however, weight gain caused by sugary drinks may not completely explain the increased diabetes risk.  There is mounting evidence that sugary drinks contribute to chronic inflammation, high triglycerides, decreased “good” (HDL) cholesterol, and increased insulin resistance, all of which are risk factors for diabetes.
What to drink in place of the sugary stuff? Water is an excellent choice. Coffee and tea are also good calorie-free substitutes for sugared beverages (as long as you don’t load them up with sugar and cream). And there’s convincing evidence that coffee may help protect against diabetes; emerging research suggests that tea may hold diabetes-prevention benefits as well, but more research is needed.
There’s been some controversy over whether artificially sweetened beverages are beneficial for weight control and, by extension, diabetes prevention. Some studies have found that people who regularly drink diet beverages have a higher risk of diabetes than people who rarely drink such beverages,but there could be another explanation for those findings: People often start drinking diet beverages because they have a weight problem or have a family history of diabetes; studies that don’t adequately account for these other factors may make it wrongly appear as though the diet soda led to the increased diabetes risk. A recent long-term analysis on data from 40,000 men in the Health Professionals Follow-Up Study finds that drinking one 12-ounce serving of diet soda a day does not appear to increase diabetes risk. So in moderation, diet beverages can be a good sugary-drink alternative.
3. Choose good fats instead of bad fats.
The types of fats in your diet can also affect the development of diabetes. Good fats, such as the polyunsaturated fats found in liquid vegetable oils, nuts, and seeds can help ward off type 2 diabetes. Trans fats do just the oppositeThese bad fats are found in many margarines, packaged baked goods, fried foods in most fast-food restaurants, and any product that lists “partially hydrogenated vegetable oil” on the label. Eating polyunsaturated fats from fish—also known as “long chain omega 3” or “marine omega 3” fats—does not protect against diabetes, even though there is much evidence that these marine omega 3 fats help prevent heart disease. If you already have diabetes, eating fish can help protect you against a heart attack or dying from heart disease.
4.  Limit red meat and avoid processed meat; choose nuts, whole grains, poultry, or fish instead.
The evidence is growing stronger that eating red meat (beef, pork, lamb) and  red meat (bacon, hot dogs, deli meats) increases the risk of diabetes, even among people who consume only small amounts. The latest support comes from a “meta analysis,” or statistical summary, that combined findings from the long-running Nurses’ Health Study I and II and the Health Professionals Follow-Up Study with those of six other long-term studies. The researchers looked at data from roughly 440,000 people, about 28,000 of whom developed diabetes during the course of the study.  They found that eating just one daily 3-ounce serving of red meat—say, a steak that’s about the size of a deck of cards—increased the risk of type 2 diabetes by 20 percent. Eating even smaller amounts of processed red meat each day—just two slices of bacon, one hot dog, or the like—increased diabetes risk by 51 percent.
Why do red meat and processed red meat appear to boost diabetes risk? It may be that the high iron content of red meat diminishes insulin’s effectiveness or damages the cells that produce insulin; the high levels of sodium and nitrites (preservatives) in processed red meats may also be to blame. Red and processed meats are a hallmark of the unhealthful “Western” dietary pattern, which seems to trigger diabetes in people who are already at genetic risk.

If You Smoke, Try to Quit

Add type 2 diabetes to the long list of health problems linked with smoking. Smokers are roughly 50 percent more likely to develop diabetes than nonsmokers, and heavy smokers have an even higher risk.

Alcohol Now and Then May Help

A growing body of evidence links moderate alcohol consumption with reduced risk of heart disease. The same may be true for type 2 diabetes. Moderate amounts of alcohol—up to a drink a day for women, up to two drinks a day for men—increases the efficiency of insulin at getting glucose inside cells. And some studies indicate that moderate alcohol consumption decreases the risk of type 2 diabetes. If you already drink alcohol, the key is to keep your consumption in the moderate range, as higher amounts of alcohol could increase diabetes risk. If you don’t drink alcohol, there’s no need to start—you can get the same benefits by losing weight, exercising more, and changing your eating patterns

G.    What parts of the body does diabetes affect ?
Knowing how diabetes affects your body can help you look after your body and prevent diabetic complications from developing.
Many of the effects of diabetes stem from the same guilty parties; namely high blood pressure, high cholesterol levels and a lack of blood glucose control.

Signs of diabetes

When undiagnosed or uncontrolled, the effects of diabetes on the body can be noticed by the classic symptoms of diabetes, namely:
·         Increased thirst
·         Frequent need to urinate
·         Fatigue
·         Blurred vision and
·         Tingling or pain in the hands, feet and/or legs

Long term effects of diabetes on the body

In addition to the symptoms, diabetes can cause long term damage to our body. The long term damage is commonly referred to as diabetic complications. Diabetes affects our blood vessels and nerves and therefore can affect any part of the body.
However, certain parts of our body are affected more than other parts.
Diabetic complications will usually take a number of years of poorly controlled diabetes to develop. Complications are not a certainty and can be kept at bay and prevented by maintaining a strong level of control on your diabetes, your blood pressure and cholesterol.
These can all be helped by keeping to a healthy diet, avoiding cigarettes and alcohol, and incorporating regular activity into your daily regime in order to keep blood sugar levels within recommended blood glucose level guidelines.

The effect of diabetes on the heart

Diabetes and coronary heart disease are closely related. Diabetes contributes to high blood pressure and is linked with high cholesterol which significantly increases the risk of heart attacks and cardiovascular disease.

Diabetes and strokes

Similar to how diabetes affects the heart, high blood pressure and cholesterol raises the risk of strokes.

How diabetes affects the eyes

A relatively common complication of diabetes is diabetic retinopathy. As with all complications, this condition is brought on by a number of years of poorly controlled or uncontrolled diabetes. Diabetic retinopathy has a number of symptoms.
Retinopathy is caused by blood vessels in the back of the eye (the retina) swelling and leaking. High blood pressure is also a contributing factor for diabetic retinopathy. Diabetic retinopathy can be treated so it’s best to catch it as early as you can. The best way to do this is to attend a retinopathy screening appointment, provided free on the NHS, once each year.
The effect of diabetes on the nerves and blood vessels can also lead to problems including:
·         Trouble with digestion
·         Sexual dysfunction
·         Slow wound healing
People with diabetes have an increased risk of developing complications but not everyone does. People with normal blood pressure, cholesterol and well controlled diabetes have a better chance of avoiding or significantly delaying long term damage to the body.
To reduce the chances of developing problems associated with diabetes, people are advised to take steps to improve their health and blood sugar levels. A good diet and regular activity is an important step in helping to reduce blood pressure and cholesterol and improve blood sugar levels.
Medication can also play a part where lifestyle changes are not sufficient. With type 1 diabetes, or other diabetes types where not enough insulin is being produced, insulin will need to be administered by injection or insulin pump.

Effect of diabetes on the kidneys

The kidneys are another organ that is at particular risk of damage as a result of diabetes and the risk is again increased by poorly controlled diabetes, high blood pressure and cholesterol. Diabetic nephropathy is the term for kidney disease as a result of diabetes.
Damage to the kidneys takes place over a period of years and can picked up by nephropathy screening before it gets too serious. Treatment includes lifestyle changes and may include medicine to treat high blood pressure and cholesterol.

Diabetes and its effects on the nerves

The effects of diabetes on the nerves can be serious as the nerves are involved in so many of our bodily functions, from movement and digestion through to sex and reproduction.
The presence of nerve damage (neuropathy) is commonly noticed by:
·         Numbness or tingling in the hands or feet
·         Lack of arousal in the penis or clitoris
·         Excessive sweating or
·         Diagnosis of delayed stomach emptying
Treatments for neuropathy concentrates on reducing pain but medication such blood pressure lowering drugs may also be prescribed to help prevent development of the condition.

Diabetes and its effect on digestion

Diabetes can affect digestion in a number of ways. If diabetes has caused nerve damage, this can lead to nausea, constipation or diarrhoea.
An alternative cause of disturbed digestion can be the result of diabetes medication. Some type 2 diabetes medications for instance are prone to causing digestive issues, although these tend to settle down after the body gets used to them.
