Blood glucose levels that are higher than normal but not yet
high enough to be diagnosed as diabetes.
People almost always develop it before being diagnosed by
Type 2 diabetes.
Recent research has shown that some long-term damage to
the body, especially the heart and circulatory system, may
already be occurring during prediabetes.

What if you are younger than 45 but overweight? Any other risks?
3- There are three different tests you can take to determine if you have
Doctors can use a fasting plasma glucose test (FPG), oral glucose
tolerance test (OGTT), or an A1C test to detect prediabetes.

2- The fasting plasma glucose test (FPG).
3- or the oral glucose tolerance test (OGTT).
RBS ( Random Blood Sugar) v.s. Postprandial blood Sugar
- RBS :measures blood glucose regardless of when you last
The reference values for a "normal" random glucose test in
an average adult are 70 - 141 mg/dl (3.9 - 7.8
mmol/l), between 140 - 200 mg/dl is considered pre-
diabetes, and > 200 mg/dl is considered diabetes according
to ADA guidelines.
- 2-hour postprandial blood sugar : measures blood glucose
exactly 2 hours after you start eating a meal.
Fasting blood glucose: Less than or equal to 110 milligrams per
deciliter (mg/dL) (6.1 millimoles per liter, or
2 hours after eating
Less than 140 mg/dL (7.8 mmol/L) for people
age 50 and younger; less than 150 mg/dL (8.3
mmol/L) for people ages 50-60; less than 160
mg/dL (8.9 mmol/L) for people age 60 and
Random (casual): Levels vary depending on when and how much
you ate at your last meal. In general: 80-120
mg/dL (4.4-6.6 mmol/L) before meals or when
waking up; 100-140 mg/dL (5.5-7.7 mmol/L) at
Q 1: Why did my doctor start me on a cholesterol-lowering drug even though my
cholesterol levels are only borderline high?
A 1: People with diabetes tend to develop heart disease with lower lipid levels than
nondiabetic patients, so some doctors try early on to lower blood lipid levels in their
patients with diabetes.
Q2: Why is it so much harder to control my blood glucose when I am sick?
A2: Being sick stresses your body, and stress can raise your blood glucose. Any kind of
stress—physical or mental—can have that effect.
Q3: Why is my blood glucose high while I am taking prednisone for my asthma?

prednisone both cause the body to make glucose when you're not eating (like during
Q4: Why did my doctor recently start me on a blood pressure medication even though
my blood pressure is only slightly elevated?
A4: High blood glucose combined with high blood pressure increases your risk of
getting diabetic kidney disease.
Q5: What can I take for a cough that is caused by my ACE inhibitor medication?
A5: One of their side benefits is to reduce blood pressure in the kidneys and to protect
them from damage. Studies have shown that these medications actually reduce the
rate of kidney damage caused by diabetes.
Q6: Should I take an aspirin daily if I have diabetes?
Q7: How high is my risk for heart attack with type 2 diabetes?
A7: A recent study has shown that people with type 2 diabetes who have not had a
heart attack still have as high a risk for a future heart attack as a person without
diabetes who has already had a heart attack.
Q8: Why do my feet burn at night when I'm trying to go to sleep?
A8: It is due to "Painful neuropathy“.
Q9: Should I be concerned about a small red blister on my foot from walking
in new shoes?
A9: Yes! If it breaks, this blister in the skin can allow germs into your foot.
Q10: Is it safe to exercise if my blood glucose is high?
A10: If your blood glucose is higher than 300 mg/dl, you should not exercise
until you have taken some fast-acting insulin and your blood glucose level is
below 250 mg/dl.
Q11: During a meal, why do I get filled up before I finish eating?
A11: It is due to "diabetic gastroparesis."
