PREDIABETES

Prediabetes means that your blood sugar level is higher than normal but not yet high enough to be type 2 diabetes. This condition will likely to progress to type 2 diabetes if you didn’t make a move such as lifestyle change, eating healthy foods,  and incorporating physical activity in your daily routine and maintaining a healthy weight.

If you have prediabetes, the long-term damage of diabetes — especially to your heart, blood vessels and kidneys — may already be starting.

Prediabetes affects adults and children. The same lifestyle changes that can help prevent progression to diabetes in adults might also help bring children’s blood sugar levels back to normal.

Prediabetes generally has no signs or symptoms. One possible sign that you may be at risk of type 2 diabetes is darkened skin on certain parts of the body. Affected areas can include the neck, armpits, elbows, knees and knuckles.

Classic signs and symptoms that suggest you’ve moved from prediabetes to type 2 diabetes include:

  • Increased thirst
  • Frequent urination
  • Fatigue
  • Blurred vision

DIAGNOSIS

There are several blood tests for prediabetes.

Glycated hemoglobin (A1C) test- This test indicates your average blood sugar level for the past two to three months. Specifically, the test measures the percentage of blood sugar attached to the oxygen-carrying protein in red blood cells (hemoglobin). The higher your blood sugar levels, the more hemoglobin you’ll have with sugar attached.

In general:

  • An A1C level below 5.7 percent is considered normal
  • An A1C level between 5.7 and 6.4 percent is considered prediabetes
  • An A1C level of 6.5 percent or higher on two separate tests indicates type 2 diabetes

Certain conditions can make the A1C test inaccurate — such as if you are pregnant or have an uncommon form of hemoglobin (hemoglobin variant).

Fasting blood sugar test- A blood sample is taken after you fast for at least eight hours or overnight.

In general:

  • A fasting blood sugar level below 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is considered normal.
  • A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L) is considered prediabetes. This result is sometimes called impaired fasting glucose.
  • A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher indicates type 2 diabetes.

Oral glucose tolerance test- This test is usually used to diagnose diabetes only during pregnancy. A blood sample is taken after you fast for at least eight hours or overnight. Then you’ll drink a sugary solution, and your blood sugar level will be measured again after two hours.

In general:

  • A blood sugar level less than 140 mg/dL (7.8 mmol/L) is considered normal.
  • A blood sugar level from 140 to 199 mg/dL (7.8 to 11.0 mmol/L) is considered prediabetes. This is sometimes referred to as impaired glucose tolerance.
  • A blood sugar level of 200 mg/dL (11.1 mmol/L) or higher indicates type 2 diabetes.

If you have prediabetes, further testing may be needed. At least once a year, your doctor will likely check your:

  • Fasting blood sugar
  • Hemoglobin A1C
  • Total cholesterol, HDL, low-density lipoprotein (LDL), and triglycerides

Testing might occur more frequently if you have additional risk factors for diabetes.

Children and prediabetes

Due to the rise in childhood obesity, type 2 diabetes is becoming more common in children and adolescents. The ADA recommends prediabetes testing for children who are overweight or obese and who have at least two other risk factors for type 2 diabetes.

These other risk factors include:

  • Family history of type 2 diabetes.
  • Race. Children who are African-American, Hispanic or Native American are at higher risk.
  • Sex and age. Type 2 diabetes is more common among girls than boys. A diagnosis of childhood type 2 diabetes often occurs during puberty — as early as age 10.
  • Low birth weight.
  • Being born to a mother who had gestational diabetes.

The ranges of blood sugar level considered normal, prediabetic and diabetic are the same for children and adults.

Children who have prediabetes should be tested annually for type 2 diabetes — or more often if the child experiences a change in weight or develops signs or symptoms of diabetes, such as increased thirst, increased urination, fatigue or blurred vision.

 

TREATMENT

Healthy lifestyle choices can help you bring your blood sugar level back to normal, or at least keep it from rising toward the levels seen in type 2 diabetes.

To prevent prediabetes from progressing to type 2 diabetes, try to:

  • Eat healthy foods. Choose foods low in fat and calories and high in fiber. Focus on fruits, vegetables and whole grains. Strive for variety to help you achieve your goals without compromising taste or nutrition.
  • Be more active. Aim for 30 to 60 minutes of moderate physical activity most days of the week.
  • Lose excess weight.  To keep your weight in a healthy range, focus on permanent changes to your eating and exercise habits. Motivate yourself by remembering the benefits of losing weight, such as a healthier heart, more energy and improved self-esteem.
  • Stop smoking.
  • Take medications as needed. If you’re at high risk of diabetes, your doctor might recommend metformin (Glucophage, others). Medications to control cholesterol and high blood pressure might also be prescribed.

Children and prediabetes treatment

Children with prediabetes should undertake the lifestyle changes recommended for adults with type 2 diabetes, including:

  • Losing weight
  • Eating fewer refined carbohydrates and fats, and more fiber
  • Spending at least one hour every day in physical activity

Medication generally isn’t recommended for children with prediabetes.

Alternative medicine

Many alternative therapies have been touted as possible ways to treat or prevent type 2 diabetes, including:

  • Banaba
  • Cassia cinnamon
  • Fenugreek
  • Ginseng
  • Gymnema
  • Mangesium
  • White mulberry

There’s no definitive evidence that any of these alternative therapies are effective although some of these substances have shown promise in early trials.

If you’re considering dietary supplements or other alternative therapies to treat or prevent prediabetes, talk to your doctor. Some of these supplements or alternative therapies might be harmful if combined with certain prescription medications. Your doctor can help you weigh the pros and cons of specific alternative therapies.
