What Is Prediabetes?

The vast majority of patients with type 2 diabetes initially had prediabetes. Their blood glucose levels where higher than normal, but not high enough to merit a diabetes diagnosis. The cells in the body are becoming resistant to insulin.

Studies have indicated that even at the prediabetes stage, some damage to the circulatory system and the heart may already have occurred.
Diabetes Is A Metabolism Disorder

Diabetes (diabetes mellitus) is classed as a metabolism disorder. Metabolism refers to the way our bodies use digested food for energy and growth. Most of what we eat is broken down into glucose. Glucose is a form of sugar in the blood - it is the principal source of fuel for our bodies.

When our food is digested, the glucose makes its way into our bloodstream. Our cells use the glucose for energy and growth. However, glucose cannot enter our cells without insulin being present - insulin makes it possible for our cells to take in the glucose.

Insulin is a hormone that is produced by the pancreas. After eating, the pancreas automatically releases an adequate quantity of insulin to move the glucose present in our blood into the cells, as soon as glucose enters the cells blood-glucose levels drop.

A person with diabetes has a condition in which the quantity of glucose in the blood is too elevated (hyperglycemia). This is because the body either does not produce enough insulin, produces no insulin, or has cells that do not respond properly to the insulin the pancreas produces. This results in too much glucose building up in the blood. This excess blood glucose eventually passes out of the body in urine. So, even though the blood has plenty of glucose, the cells are not getting it for their essential energy and growth requirements.
How To Determine Whether You Have Diabetes, Prediabetes or Neither

Doctors can determine whether a patient has a normal metabolism, prediabetes or diabetes in one of three different ways - there are three possible tests:
The A1C test
- at least 6.5% means diabetes
- between 5.7% and 5.99% means prediabetes
- less than 5.7% means normal
The FPG (fasting plasma glucose) test
- at least 126 mg/dl means diabetes
- between 100 mg/dl and 125.99 mg/dl means prediabetes
- less than 100 mg/dl means normal

An abnormal reading following the FPG means the patient has impaired fasting glucose (IFG)
The OGTT (oral glucose tolerance test) 
- at least 200 mg/dl means diabetes
- between 140 and 199.9 mg/dl means prediabetes
- less than 140 mg/dl means normal
An abnormal reading following the OGTT means the patient has impaired glucose tolerance (IGT)
Why Is It Called Diabetes Mellitus?

Diabetes comes from Greek, and it means a "siphon". Aretus the Cappadocian, a Greek physician during the second century A.D., named the condition diabainein. He described patients who were passing too much water (polyuria) - like a siphon. The word became "diabetes" from the English adoption of the Medieval Latin diabetes.

In 1675, Thomas Willis added mellitus to the term, although it is commonly referred to simply as diabetes. Mel in Latin means "honey"; the urine and blood of people with diabetes has excess glucose, and glucose is sweet like honey. Diabetes mellitus could literally mean "siphoning off sweet water".

In ancient China people observed that ants would be attracted to some people's urine, because it was sweet. The term "Sweet Urine Disease" was coined.

Controlling Diabetes - Treatment Is Effective And Important

All types of diabetes are treatable. Diabetes type 1 lasts a lifetime, there is no known cure. Type 2 usually lasts a lifetime, however, some people have managed to get rid of their symptoms without medication, through a combination of exercise, diet and body weight control.


Patients with type 1 are treated with regular insulin injections, as well as a special diet and exercise.Researchers from the Mayo Clinic Arizona in Scottsdale showed that gastric bypass surgery can reverse type 2 diabetes in a high proportion of patients. They added that within three to five years the disease recurs in approximately 21% of them. Yessica Ramos, MD., said "The recurrence rate was mainly influenced by a longstanding history of Type 2 diabetes before the surgery. This suggests that early surgical intervention in the obese, diabetic population will improve the durability of remission of Type 2 diabetes." (Link to article)

Patients with Type 2 diabetes are usually treated with tablets, exercise and a special diet, but sometimes insulin injections are also required.


  • If diabetes is not adequately controlled the patient has a significantly higher risk of developing complications.
  • Complications linked to badly controlled diabetes:
  • Eye complications - glaucoma, cataracts, diabetic retinopathy, and some others.
  • Foot complications - neuropathy, ulcers, and sometimes gangrene which may require that the foot be amputated
  • Skin complications - people with diabetes are more susceptible to skin infections and skin disorders
  • Heart problems - such as ischemic heart disease, when the blood supply to the heart muscle is diminished
  • Hypertension - common in people with diabetes, which can raise the risk of kidney disease, eye problems, heart attack and stroke
  • Mental health - uncontrolled diabetes raises the risk of suffering from depression, anxiety and some other mental disorders
  • Hearing loss - diabetes patients have a higher risk of developing hearing problems
  • Gum disease - there is a much higher prevalence of gum disease among diabetes patients
  • Gastroparesis - the muscles of the stomach stop working properly
  • Ketoacidosis - a combination of ketosis and acidosis; accumulation of ketone bodies and acidity in the blood.
  • Neuropathy - diabetic neuropathy is a type of nerve damage which can lead to several different problems.
  • HHNS (Hyperosmolar Hyperglycemic Nonketotic Syndrome) - blood glucose levels shoot up too high, and there are no ketones present in the blood or urine. It is an emergency condition.
  • Nephropathy - uncontrolled blood pressure can lead to kidney disease
  • PAD (peripheral arterial disease) - symptoms may include pain in the leg, tingling and sometimes problems walking properly
  • Stroke - if blood pressure, cholesterol levels, and blood glucose levels are not controlled, the risk of stroke increases significantly
  • Erectile dysfunction - male impotence.
  • Infections - people with badly controlled diabetes are much more susceptible to infections
  • Healing of wounds - cuts and lesions take much longer to heal


Some Facts And Myths Regarding Diabetes

Many presumed "facts" are thrown about in the paper press, magazines and on the internet regarding diabetes; some of them are, in fact, myths. It is important that people with diabetes, pre-diabetes, their loved ones, employers and schools have an accurate picture of the disease. Below are some diabetes myths:

  • People with diabetes should not exercise - NOT TRUE!! Exercise is important for people with diabetes, as it is for everybody else. Exercise helps manage body weight, improves cardiovascular health, improves mood, helps blood sugar control, and relieves stress. Patients should discuss exercise with their doctor first.
  • Fat people always develop type 2 diabetes eventually - this is not true. Being overweight or obese raises the risk of becoming diabetic, they are risk factors, but do not mean that an obese person will definitely become diabetic. Many people with type 2 diabetes were never overweight. The majority of overweight people do not develop type 2 diabetes.
  • Diabetes is a nuisance, but not serious - two thirds of diabetes patients die prematurely from stroke or heart disease. The life expectancy of a person with diabetes is from five to ten years shorter than other people's. Diabetes is a serious disease.
  • Children can outgrow diabetes - this is not true. Nearly all children with diabetes have type 1; insulin-producing beta cells in the pancreas have been destroyed. These never come back. Children with type 1 diabetes will need to take insulin for the rest of their lives, unless a cure is found one day.
  • Don't eat too much sugar, you will become diabetic - this is not true. A person with diabetes type 1 developed the disease because their immune system destroyed the insulin-producing beta cells. A diet high in calories, which can make people overweight/obese, raises the risk of developing type 2 diabetes, especially if there is a history of this disease in the family.
  • I know when my blood sugar levels are high or low - very high or low blood sugar levels may cause some symptoms, such as weakness, fatigue and extreme thirst. However, levels need to be fluctuating a lot for symptoms to be felt. The only way to be sure about your blood sugar levels is to test them regularly. Researchers from the University of Copenhagen, Denmark showed that even very slight rises in blood-glucose levels significantly raise the risk of ischemic heart disease. (Link to article)
  • Diabetes diets are different from other people's - the diet doctors and specialized nutritionists recommend for diabetes patients are healthy ones; healthy for everybody, including people without the disease. Meals should contain plenty of vegetables, fruit, whole grains, and they should be low in salt and sugar, and saturated or trans fat. Experts say that there is no need to buy special diabetic foods because they offer no special benefit, compared to the healthy things we can buy in most shops.
  • High blood sugar levels are fine for some, while for others they are a sign of diabetes - high blood-sugar levels are never normal for anybody. Some illnesses, mental stress and steroids can cause temporary hikes in blood sugar levels in people without diabetes. Anybody with higher-than-normal blood sugar levels or sugar in their urine should be checked for diabetes by a health care professional.
  • Diabetics cannot eat bread, potatoes or pasta - people with diabetes can eat starchy foods. However, they must keep an eye on the size of the portions. Whole grain starchy foods are better, as is the case for people without diabetes.
  • One person can transmit diabetes to another person - NOT TRUE. Just like a broken leg is not infectious or contagious. A parent may pass on, through their genes to their offspring, a higher susceptibility to developing the disease.
  • Only older people develop type 2 diabetes - things are changing. A growing number of children and teenagers are developing type 2 diabetes. Experts say that this is linked to the explosion in childhood obesity rates, poor diet, and physical inactivity.
  • I have to go on insulin, this must mean my diabetes is severe - people take insulin when diet alone or diet with oral or non-insulin injectable diabetes drugs do not provide good-enough diabetes control, that's all. Insulin helps diabetes control. It does not usually have anything to do with the severity of the disease.
  • If you have diabetes you cannot eat chocolates or sweets - people with diabetes can eat chocolates and sweets if they combine them with exercise or eat them as part of a healthy meal.
  • Diabetes patients are more susceptible to colds and illnesses in general - a person with diabetes with good diabetes control is no more likely to become ill with a cold or something else than other people. However, when a diabetic catches a cold, their diabetes becomes harder to control, so they have a higher risk of complications.
