WHAT IS DIABETES?
Most of the food consumed by an individual is converted in to glucose by the body through the normal metabolic process and transferred to all parts of the body by the blood. This glucose or sugar is used by the body as energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn’t make enough insulin or can’t use its own insulin as well as it should. This causes sugar to build up in your blood. Diabetes is a disease in which blood glucose levels are above normal.
Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations. Diabetes is the sixth leading cause of death in the world.
WHAT ARE THE TYPES OF DIABETES?
Diabetes is of following types:
Who is likely to suffer from diabetes?
As yet there has been no universally accepted theory as to the cause and cure of diabetes. It is regarded as due to a disease of the pancreas, of the muscles, of the nervous system, of the kidneys. Sometimes it has been considered as a metabolic and nutritional disturbance, and still again as a form of autotoxemia and acidosis.
The body in which diabetes develops generally is considered to have been supplied with an over-abundance of sugar and starch foods. One reason for this belief, of course, is the appearance, in those affected by the disease, of an abnormal amount of sugar in the blood and the excretion of sugar in urine, where it does not belong. It is true that the diabetic is unable to deal with sugars and other carbohydrate foods satisfactorily. But when the body has been overfed on all classes of food, it can not be expected to assimilate properly any class.
It is the disturbance of metabolic processes by this over taxation that accounts for the body’s comparatively ready response to a program of diet and hygiene which allows recovery of a normal metabolic balance. Many cases of this disease, some of which have been “given up” under orthodox treatment, have been greatly benefited or corrected entirely through the fast, the fruit diet, the milk diet, and suitable exercise. Action taken to control glucose levels in the food and as a result in the blood can prevent or delay the onset of symptoms.
Diabetes is likely to develop in people who:
WHAT ARE THE SIGNS AND SYMPTOMS OF DIABETES?
It’s not unusual to have diabetes mellitus and yet have no symptoms. Type 2 diabetes, in particular, develops slowly. Many people have type 2 diabetes for as long as eight years before it is diagnosed. When symptoms do develop, they often vary. But two symptoms that occur in many people with the disease are increased thirst and frequent urination.
That’s because excess glucose circulating in your body draws water from your tissues, making you feel dehydrated. To quench your thirst, you drink a lot of water and other beverages, and that leads to more frequent urination.
Another condition, diabetes insipidus, also causes increased thirst and urination, but despite the similar name and symptoms, it’s not related to diabetes mellitus. Diabetes insipidus isn’t caused by a problem with blood sugar, but rather by a hormone disorder originating in the pituitary gland in your brain that makes your kidneys unable to conserve water.
This is a disease that often is well established before it is suspected. Its onset is gradual as a rule but may develop abruptly after some severe shock. It may appear at any age, but the usual age is from thirty to sixty. When it appears in early life the outlook is far from bright. Other warning signs of diabetes mellitus include:
Nausea, vomiting, or stomach pains may accompany some of these symptoms in the abrupt onset of insulin-dependent diabetes, called type 1 diabetes.
Often diabetes goes undiagnosed because many of its symptoms seem so harmless. The early detection of diabetes symptoms and treatment can decrease the chance of developing the complications of diabetes.
WHAT ARE THE COMPLICATIONS OF DIABETES?
Sometimes a complication of diabetes may give a clue to the presence of the disease. The principle complications associated with diabetes are retinopathy, neuropathy, nephropathy and arteriosclerosis.
Keeping blood sugar levels as close to normal as possible through aggressive management slows the onset and progression of eye, kidney and nerve diseases caused by diabetes. In fact it demonstrated that any sustained lowering of blood sugar helps, even if the person has a history of poor control.
Lowering and maintaining more constant blood sugar levels reduced the risk of eye disease by 76%, kidney disease by 50%, nerve disease by 60% and cardiovascular disease by 35%.
Micro vascular and cardiovascular complications of diabetes (renal failure and myocardial infarction) are the major causes of morbidity in diabetics. These complications are responsible for a reduction in the life expectancy of a newly diagnosed insulin dependent diabetic by about one-third. The basis of managing diabetes is an improvement in the lifestyle of the diabetic and prevention of complications responsible for morbidity and mortality in diabetes.
Major complications of diabetes are:
It usually takes between 10-13 years for diabetic retinopathy to develop and it is present in some degree in most diabetics who have had the disease for 20 years. In only about half of the diabetics who develop it however, is vision markedly impaired and blindness occurs in only about 6%. Still, diabetes is the leading cause of blindness in adults 20 to 74 years old. Two other complications of diabetes, cataracts and glaucoma, can also lead to loss of vision.
The incidence of coronary occlusion in persons with clinical diabetes has been estimated at from 8-17% with diabetic adults having heart disease death rates about 2 to 4 times as high as the general population. The risk of stroke is also found to be 2 to 4 times higher in people with diabetes. Arteriosclerosis obliterans in the lower extremities, a form of the peripheral vascular disease, may produce disturbances in sensation, decrease in muscular endurance, intermittent claudication on effort, the absence of peripheral pulses in the lower legs and feet and gangrene, and ultimately lead to amputation of the extremity. Diabetic gangrene usually involves the toes, heels or other prominent parts of the feet and is precipitated by trauma, infection or extremes in temperature. Careful attention to proper foot care, avoidance of injury and consistent use of methods to improve peripheral circulation, including withdrawal from tobacco use in any form, are critical for the diabetic. The aetiology of large vessel disease is multi-factorial in the diabetic as well as the non-diabetic population with lipoprotein metabolism, hypertension, physical activity, obesity, cigarette smoking, stress, personality and genetic and racial factors all playing a part.
Majority of diabetics have hypertension and two thirds show significant albuminuria, but the fully developed nephrotic syndrome of hypertension, proteinuria and oedema occurs in less than 10% and renal function is impaired in only one half to three quarters of those patients.
Like other long-term complications, good blood glucose control goes a long way towards reducing the risk of diabetic nephropathy. In addition to monitoring the blood sugar levels, periodic monitoring of a diabetic patient’s kidney function (blood urea nitrogen, uric acid, creatinine and creatinine clearance) is important.
The symptoms of Ketoacidosis are:
The presence and level of Ketoacids in the urine can be checked by using a urine dip stick at home.
WHAT ARE THE CAUSES OF DIABETES MELLITUS?
Diabetes is the direct result of reduced insulin levels in the blood when the pancreas does not produce enough insulin or the insulin available in the blood does not work effectively. As a result of this blood sugar levels go up.
The causes of type 1 diabetes appear to be much different than those for type 2 diabetes, though the exact mechanisms for developing both diseases are unknown. The appearance of type 1 diabetes is suspected to follow exposure to an “environmental trigger,” such as an unidentified virus, stimulating an immune attack against the beta cells of the pancreas in some genetically predisposed people.
Diabetes could be caused by multifarious causes:
In Type 1 diabetes, however, only 40 to 50 percent of the second twins will develop the disease. Apparently while inheritance is important, environmental factors and lifestyles (for example, too much food, too much stress, viral infection, and so forth) also play a vital role in the development of Type 1 diabetes.
Until then the result is a lack of available insulin. While the onset is said to be sudden, changes resulting in decreased insulin availability may have occurred over a longer period of time. In short, insulin-dependent diabetes mellitus is an inherited defect of the body’s immune system, resulting in the destruction of the insulin-producing beta cells of the pancreas. It’s not clear why this happens, but a number of explanations and possible triggers of this reaction have been proposed. These include:
CAUSES OF TYPE 2 DIABETES
Type II (Adult Onset) diabetes is a sugar disease. You can control it, even prevent it. It appears when:
WHAT ARE THE RISK FACTORS FOR DIABETES?
Risk factors are less well defined for type 1 diabetes. Some of these could be:
The following risk factors increase the chances of someone developing Type 2 diabetes:
Gestational diabetes risk factors include:
Rarer causes of diabetes, may account for 1% to 2% of all diagnosed cases, include:
WHAT ARE THE MYTHS ABOUT CAUSES OF DIABETES
Various causes without any scientific basis are propagated about the onset of diabetes.
Eating sweets or the wrong kind of food does not cause diabetes. However, it may cause obesity and this is associated with people developing Type 2 diabetes.
Stress does not cause diabetes, although it may be a trigger for the body turning on itself as in the case of Type 1 diabetes. It does, however, make the symptoms worse for those who already have diabetes.
Diabetes is not contagious. Someone with diabetes cannot pass it on to anyone else.
CAN DIABETES BE PREVENTED?
After perusal of the causes of diabetes it is apparent that certain causes can definitely be controlled. This is more important for people with the history of the disease in the family. Precautionary steps taken during early years of life can definitely prevent or delay the onset of diabetes in such cases. Non-diabetic people should avoid a lifestyle that puts them at greater risk for this disease.
Obesity and physical inactivity are the 2 major factors for diabetes and both can be controlled. Type II (Adult Onset) diabetes is a sugar disease. You can even prevent it by following simple steps:
WHAT SHOULD BE THE DIETARY PATTERN FOR A DIABETIC?
Diet plays a significant role in the health of an individual. Most times improper foods are taken due to ignorance, family traditions/myths, economic conditions and non-availability of better options. There can not be a specific diet for all and the same dietary pattern may not suit the same person for very long. One has to evolve a diet suitable for individual needs as per genetic and ethnic group food priorities.
Excluding the Eskimos and some other highly specialized ethnic groups, all diets must adhere to the same few macronutrient rules. For example:
RECOMMENDED TO BE AVOIDED
TO BE AVOIDED
You need to avoid being obese. In any case there are hardly any lean and muscular diabetics. Consult your physician to plan your exercise pattern.
Walking is the best exercise. This will reduce your blood sugar and improve the metabolic rate. Good metabolism means burning calories even when sitting idle. You can walk to the office from the car park- park at a little distance. Use the stairs and adopt various other ways to burn calories rather than saving them.
WHAT TREATMENT IS AVAILABLE FOR DIABETES?
People can and do live healthy and happy lives with diabetes. People with diabetes must take responsibility for their day-to-day care, and keep blood glucose levels from going too low or too high. In response to the growing health burden of diabetes, the diabetes community has three choices: prevent diabetes; cure diabetes; and improve the quality of care of people with diabetes to prevent devastating complications.
Diabetes knowledge, treatment, and prevention strategies are essential.
Diabetes is a condition in which there can be no great amount of compromise; a rigid treatment must be followed. It is necessary that food be utilized, that sugar taken in as such or formed from starch foods be oxidized, and exercise is the only way in which this can be assured in a physiological manner. Planned and a well-balanced diet along with rigid exercise schedule helps. However, even greater benefit will result from general exercises involving every muscle group in the body. There must be enough exercise to increase heart and lung activity so that muscle-sugar will be burned up and so that there will be no appreciable amount of sugar stored within the body. Naturally there must be plenty of relaxation but the tendency to lie around and coddle the disease may lead to succumbing quickly from diabetes.
TREATMENT OF TYPE 1 DIABETES: Lack of insulin production by the pancreas makes type 1 diabetes particularly difficult to control. Treatment requires a strict regimen that typically includes a carefully calculated diet, planned physical activity, home blood glucose testing several times a day, and multiple daily insulin injections.
TREATMENT OF TYPE 2 DIABETES: Treatment typically includes diet control, exercise, home blood glucose testing, and in some cases, oral medication and/or insulin. Approximately 40% of people with type 2 diabetes require insulin injections.
People with diabetes should see a health care provider who will monitor their diabetes control and help them learn to manage their diabetes. In addition, people with diabetes may see endocrinologists, who may specialize in diabetes care; ophthalmologists for eye examinations; podiatrists for routine foot care; and dietitians and diabetes educators who teach the skills needed for daily diabetes management.
WHAT IS THE CURE FOR DIABETES?
Several approaches to “cure” diabetes are being pursued:
Transplant patients must take powerful drugs for the rest of their lives. These drugs suppress their immune system, to avoid rejection of the transplant. Having a suppressed immune system leaves the body with very little protection from other diseases, so pancreas transplants are not the answer.
If your child has type 2 diabetes, it may be possible for him to stop taking medicine one day. Some people with type 2 diabetes are able to manage diabetes by treating it with exercise and careful meal planning. But this is not a cure. Careful meal planning and exercise may help children with type 1 diabetes reduce the amount of insulin they take, stay within their target range, and feel better.
Each of these approaches still has a lot of challenges, such as preventing immune rejection; finding an adequate number of insulin cells; keeping cells alive; and others. But progress is being made in all areas
