Diabetes Mellitus (DM) is a disease caused by a high level of sugar in the bloodstream. This occurs due to a low level of insulin hormone or resistance to insulin hormone which regulates the blood sugar level. If not managed properly, Diabetes Mellitus may lead to complications such as damage to eyes, kidneys or nerves.

According to the World Health Organization, 422 million adults had Diabetes Mellitus in 2014. That accounts for 6% of the world population.

Prediabetes is a condition in which blood sugar level is slightly higher than normal but not high enough to confirm Type 2 Diabetes Mellitus. So, doctors consider pre-diabetes as a warning sign for Diabetes Mellitus.

But the good news is, it is always possible to reverse prediabetes status from developing into Type 2 Diabetes Mellitus.

In the US, about 86 million people over 20 years have prediabetes. Worldwide, one out of three people has prediabetes.

We have previously discussed the difference between different types of diabetes. The goal of this article is to discuss the key difference between prediabetes and diabetes.

Symptoms

Prediabetes has no specific signs or symptoms. A few features suggestive of the condition are:

  • Discolouration of skin on the neck, groin, knuckles, armpit, etc.
  • Unexplained tiredness
  • Excessive thirst
  • Frequent urination
  • Unexplained weight loss
  • Blurred vision
  • Slow healing wounds, cuts sores and recurring infections
  • Dry mouth
  • Itchy skin

Do you know the early warning signs of diabetes in men, signs in women and symptoms of diabetes in children? I have noted them in three separate articles. Just follow the links.

Risk factors

The risk factors for prediabetes are as same as for Type 2 Diabetes Mellitus. They are as follows.

1. A family history of Type 2 Diabetes Mellitus among your parents or siblings is a significant risk factor.

2. Overweight; especially increase the waist measurement.

The healthy Body Mass Index (BMI) is between 18.5 – 24.9 Kg/m2. BMI over 25 Kg/m2 increases pre-diabetes and diabetes risk.

Similarly, a waistline of a >40 inches in a male and >35 inches in a female increase the risk of pre-diabetes and Type 2 Diabetes Mellitus.

3. Low level of physical activities and sedentary lifestyle is a risk factor

4. Smoking increases the risk of pre-diabetes and diabetes.

5. Polycystic ovarian syndrome increases the risk of having pre-diabetes due to increased insulin resistance in the female.

6. Gestational Diabetes Mellitus during pregnancy

increases the risk of developing pre-diabetes and Type 2 DM later in life.

7. Race/ Ethnicity

Some races and ethnic group are more prone to get pre-diabetes and Type 2 Diabetes Mellitus.

Examples –African Americans, Mexican Americans, American Indians, Native Hawaiians, Pacific Islanders and Asian Americans.

8. Age over 45 years

As we grow older, the risk of developing pre-diabetes and Type 2 Diabetes Mellitus also increases.

9. Sleep disorders may cause insulin resistance, which may lead to pre-diabetes status.

10. High blood pressure and high cholesterol levels are also risk factors.

Pre-diabetes status has no symptoms or signs. Doctors commonly find it accidentally during regular medical check-ups or when they investigate blood for another health condition.

Diagnosis

The tests to diagnose pre-diabetes are the same as for Type 2 Diabetes Mellitus. It is essential to carry out the tests in a slandered way for an accurate diagnosis.

1. Fasting blood glucose level

It is measured after 8-10 hours of fasting. The results interpret as follows.

  • o <100mg/dL – normal blood sugar level
  • o 100 – 125mg/dL – impaired fasting blood sugar level (pre-diabetes)
  • o >125mg/dL – may consider as Diabetes Mellitus (need two values in separate occasions to confirm)

Some of the recommended blood glucose level monitors are below

2. Oral glucose tolerance test

Following 8 hours of fasting, can take the first blood sample. Then you have to drink a glucose solution, and then take another blood sample after two hours. Test values interpret as follows:

  • o <140mg/dL – normal sugar level
  • o 140 – 199mg/dL – impaired glucose tolerance (pre-diabetes)
  • o >200mg/dL – diagnose as Diabetes Mellitus

3. Glycated hemoglobin level (HbA1C) This test reflects the average blood sugar level in our blood during the last 3 months. The test result interprets as below:

        • <5.6% we consider as normal
        • 5.7 – 6.4% consider as pre-diabetes
        • >6.5% it confirms Diabetes Mellitus

Results from the above blood tests can confirm one’s diabetes status.

Now the question is “I have pre-diabetes status. Would I get diabetes in the near future?”

The answer is “NO”. The American Diabetes Association states that “It is possible to prevent pre-diabetes from developing into Type 2 DM by modifying our lifestyle”.

Management

Let us find out the ways to reduce the risks of developing Diabetes Mellitus from pre-diabetes status or normal blood sugar levels.

  • Healthy food habits

We have to plan our diet well. The plan should include the reduction of high calorie and fatty food intake. They are butter, full cream milk, fast food, biscuits, cakes and any other type of ‘junk food’. Instead, increase the consumption of high fiber vegetables, fruits, green leaves and whole-grain meals.

  • Regular physical activities

Regular moderate exercises such as brisk walking, cycling and swimming at least 30 minutes per day will help you to prevent Diabetes Mellitus.

When we do exercises, our cells need more glucose. Because of the requirement, glucose molecules go inside the cells with little help of insulin. That will lead our body to become less insulin resistance.

Physical activities also help us to reduce stress and feel fresh.

  • Weight reduction

If you are overweight or obese, Changes to lifestyle, healthy food and exercises will inevitably lead to weight reduction. Weight loss enhances insulin action and reduces insulin resistance.

Reduction of 5 – 10% of your body weight will do a great job to reduce the risk of developing pre-diabetes and Diabetes Mellitus.

  • Reduce stress

Long term stress triggers hormones that increase our appetite resulting in many bad outcomes. Meditation, music, travelling, exercises, etc. could help with reducing stress levels.

  • Maintaining blood pressure and cholesterol level healthy is also vital to prevent developing pre-diabetes and Type 2 Diabetes Mellitus.

If we adhere to a healthy lifestyle, we can prevent developing Type 2 Diabetes Mellitus from pre-diabetes in the majority of cases. Some would be even able to reverse pre-diabetes status to healthy blood glucose levels.

    Dear Shani, 

    This is an awesome article on diabetics. I do not know much about prediabetes because of all that is common in diabetics but now I understand the difference and how to identify diabetes early at the pre-diabetes stage itself. 

    My question is can a teenager or a youth be diagnosed with diabetes? 

    I will be looking forward to your reply. Thanks for sharing this informative and educative post.

      Dear Lok,

      Thanks for the question. Sorry for the delay in reply – your message has slipped through the cracks somehow.

      Yes, teenagers can be diagnosed with diabetes. Most of the time diabetes diagnosed in childhood and younger ages are Type 1. Some people with Type 2 Diabetes are diagnosed early as in childhood, although Type 2 is most commonly diagnosed in adults over 40 years.

      To put into perspective, in the US, approximately 18,000 people under 20 years were diagnosed with Type 1 Diabetes in comparison to Approximately 5,000 diagnosed with Type 2 (2011/12 Stats).

      The trend is upward, and the Type 1 prevalence rises by 2% and Type 2 by 5%, annually.

      I hope this clarifies the answer to your question.

      Kind regards.

      P.S. I have touched on the question in the article about the Difference between Type 1 and Type 2 Diabetes.

    Hello Shani,

    Diabetes is a condition that is growing at a very alarming rate in our society. This is partly due to people unhealthy lifestyle, and nonchalance about the type of diet individuals indulge in.

    It is a good job your doing by sensitizing people about risk factors which can cause diabetes. I wish a lot more people will take and make use of this information. Type 2 diabetes is easy to manage, if individuals with this condition are willing to exercise discipline and work on their lifestyle.

    I would add that when you want to do your diabetes analysis, it is advisable that after 17 o’clock you do not eat or drink water; the next day you make your first set of analyzes. Am I correct?

    I know diabetes is a dangerous disease and it is advisable to see a doctor rather than trying to treat yourself. A change in diet, movement, weight loss are prevention methods, as you mentioned in the article. 

    Thanks for posting.

      Hi Carmen,

      Thanks for sharing your experience with prediabetes and diabetes.

      The current guidelines by The European Society of Cardiology recommend a minimum of 8-hour fasting, but some practices recommend 10 – 12 hours fasting as the requirement. Therefore, if your plan is to check the glucose level at 7 am (next day), you need to start fasting only between 7 – 9 pm, not from 5 pm.

      Hope this helps.

    The difference between diabetes and pre diabetes is easy, straight forward and simple just as there names. Diabetes is a disease caused by a high level of blood sugar, this usually occurs due to the low insulin hormones. While pre diabetes is the when the blood sugar is a little above normal.

    Hi Shani,

    I appreciate this informative article on the difference between pre-diabetes and diabetes. I have most of the risk factors you’ve listed and have been diagnosed as pre-diabetic at various times over the years. Currently, my blood sugar levels are in the normal range due to vigilance with my diet. This post serves as an excellent reminder to stay on top of things because diabetes is such a debilitating disease. Thanks for the useful info!
