This article will discuss blood sugar levels – what tests are done to
find these levels, what average levels are and what happens when levels
become too high or too low.
Normal Blood Sugar Levels
The prime source of energy for animal and human cells is glucose
which is a kind of sugar which passes thru the blood system. When you
eat carbohydrates, glucose goes through your body. The levels of
glucose are kept normal by glucagon and insulin. Insulin is the hormone
which is generated in the pancreas and discharged into the blood system
when levels of glucose rise.
The normal level for glucose is usually 70 and 150 mg. These levels
are typically lowest when waking up, and rise following meals. Levels
of blood sugar consistently higher then 150 are a sign of high blood
sugar also known as hyperglycemia. When the blood sugar level
persistently falls to 70 are lower this is a sign of low blood sugar
also know as hypoglycemia.
Low blood sugar is a prospectively fatal condition. The symptoms or
signs of hypoglycemia are weakened mental functioning, lethargy,
unconsciousness as well as irritability. Continual hyperglycemia causes
diabetes mellitus, which is the most frequent disease connected to the
regulation of blood sugar. Diabetes is a disease which can cause kidney, nerve and eye damage.
Diabetes Blood Sugar Levels
In making the diagnosis of diabetes,
doctors first and foremost use the end results of particular glucose
tests. But, test outcomes are just one element of all the data which
goes into the conclusion for a diagnosis of Type 1 or Type 2 diabetes.
Physicians also look into the outcomes of your physical assessment,
presence or lack of signs, and health record.
Also, some drugs may change your blood glucose levels which will then
go back to usual after the illness has gotten better. Many people who
are very ill will have transient problems with elevated blood glucose
levels. These are mostly commonly due to medications such as steroids
and certain diuretics, such as water pills.
The 2 major tests run to determine the existence of blood glucose
difficulties are the total amount of glucose levels in the blood system
all through a fast during the night and level of the body’s capacity to
properly handle the surplus sugar in the blood after drinking a drink of
very high glucose.
Oral Glucose Tolerance Test
The “oral glucose tolerance test” is a test that may be carried out
in a physician’s office or a lab. The individual being checked begins
the test in a fasting condition (having neither drink nor food except
water for no less than 10 hours but not longer than 16 hours.)
Beginning blood glucose is taken and after that the individual is
asked to drink a “glucola” which is a drink with elevated amounts of
sugar in it. The individual then has their blood analyses done at ½
hour, 1 hour, 2 hours, and 3 hours after consuming the “glucola”.
In order to get trustworthy results with this test, the individual
should be in fine health and not ill – not even as minor as a cold. As
well, the individual should be regularly active. For example, not
detained to a bed like a hospital patient or lying down, and should as
well not be using any drugs which could have an effect on the blood
sugar. On the morning of the analysis, the individual should not drink
coffee or smoke. Throughout this examination, the individual should sit
or lie calmly.
This test to measure the glucose tolerance is done by analyzing the
level of blood glucose 5 times during a time frame of 3 hours. In an
individual with no diabetes, the blood glucose levels will rise after
drinking the glucose drink, and then fall rapidly back to regular
levels. This is because of the production of insulin in reaction to the
glucose and this insulin has a normalizing effect of lowering the blood
sugar level.
In a person with diabetes, levels of glucose rises higher than normal
after consuming the glucose drink and then drops back to normal levels
much slower. This is because insulin is either not being generated, or
it is generated but the body cells are unable to react to it.
As with random blood glucose or fasting tests, an obviously
uncharacteristic oral glucose tolerance test is analytical of diabetes.
But, measurements of blood glucose during the tolerance of glucose
test may fluctuate to some extent. Because of this, if or when the test
demonstrates that you have a mild elevation of glucose levels in the
blood, the physician may need to redo the test in order to make certain
of a correct diagnosis.
These tolerances for glucose tests can lead to 1 of the below diagnoses:
Standard Reaction
An individual is known as having a normal/standard response if the 2-hour sugar level is equal to and less than 110 mg/dL.
Impaired Glucose Tolerance
When an individual has results which are the same as or greater than
110 and less than 126 mg/dL, they are said to have weakened or impaired
glucose fasting. This is regarded as a risk for potential diabetes in
the future and will possible set up another test in the future. But the
results by itself, does not formulate the diabetes diagnosis.
An individual is alleged to have impaired glucose tolerance when the
2-hour glucose end results from the oral glucose tolerance test are
larger than or equal to 140 but below the level of 200 mg/dL. There is
as well a risk factor for diabetes in the future. There are currently
conversations on lowering the higher value to 180 mg/dL in order to make
a diagnosis of mild diabetes earlier in order to allocate quicker
intercession and avoid many of the complications of diabetes.
Diabetes
An individual is diagnosed as a diabetic when oral glucose tolerance
tests confirm the glucose level in the blood at 2 hrs is more than or
equal to 200 mg/dL. This needs to be verified by a 2nd test on a
different day. Currently there are some conversations about lowering
the higher value to 180 mg/dL to diagnose more individuals with mild
diabetes in order to allocate quicker intercession and avoid many of the
complications of diabetes.
Gestational Diabetes
A woman is diagnosed with gestational diabetes
when pregnant and having any 2 of the following results: a fasting
glucose level higher than 105 mg/dL, a 1-hour glucose level higher than
190 mg/dL, a 2-hour glucose level higher than 165 mg/dL, or a 3-hour
higher than 145 mg/dL.
How to Control Blood Sugar Levels
If a person experiences blood sugar levels which are too high, the
individual is further likely to develop severe health situations, such
as infections, problems with blood clotting, and the failure of cuts and
wounds to repair. High levels of sugar or glucose can as well lead to
problems such as diabetes. Happily, there are several steps which can
be taken to lower blood glucose levels.
A simple way to lessen glucose levels is to remain fit as well as
healthy. Exercising on a regular basis not only aids lower blood
glucose levels but also facilitates the fighting of infections.
Remaining energetic and taking expected exercise can also assist with
blood pressure difficulties. Exercise also helps to manage the body’s
mass and controls cholesterol levels.
This daily exercise does not need to be an exhausting workout. 30
minutes of daily exercise, even just walking, will assist to lower blood
glucose levels. Walking to the store instead of driving is really all
which may be essential to supply any individual with some much needed
exercise. Any addition exercise, such as working out in a gym, needs to
be talked about with a physician initial especially if a person has
uneven blood glucose levels.
The food which an individual eats can as well play a part in
assisting to lower blood glucose levels. Low-glycemic foods which are
digested more unhurriedly by the body are a healthier alternative.
High-glycemic foods go into the blood system effortlessly and swiftly,
which causes the pancreas to work harder to generate insulin.
Low-glycemic foods which assist lower blood glucose levels consist of
high fiber fruits, peanuts, oatmeal, bean, granola and peas.
High-glycemic foods comprise rice, white bread and potatoes.
Investigate has shown that white bread and potatoes are converted
intensely quickly by the body into glucose. In fact, they are changed
more rapidly than a candy bar would be.
To be avoided at all cost is fast foods. The sugar and fat content
in fast foods is tremendously high. Look for healthier alternatives.
Most food packaging now contain information on the food’s content of
sugar. Many restaurants and most fast food outlets now have healthy
meal alternatives such as fish dishes as well as salads.
Average Blood Glucose Levels
Random
The “random blood glucose” test may be taken at any time in related
to eating or drinking and can be administrated at any time. A level
higher than 140 mg/dL can indicate prediabetes. A level above 200mg/dL
indicates Type-1 or Type-2 diabetes and suggests further tests.
Fasting
The “fasting blood glucose” test must have the individual fasting for
at least 8 hours. Normal levels for this test are 70 to 100 mg/dL.
Higher levels indicate prediabetes and higher than 125 mg/dL suggest
diabetes either Type-1 or Type-2 and suggest further testing.
Oral Glucose Tolerance
This test also needs to be done after fasting, drinking of a glucose
drink and another hour wait. A beginning test is done and then repeated
every 1 or 2 hours. Normal levels are below 140 mg/dL. Levels of 140
to 199 mg/dL indicate prediabetes and level above 200 mg/dL suggest
diabetes with further testing needed.
A1C
The is the glycated hemoglobin test which measures blood glucose
level averaged over a 2 to 3 month period. The value is a percentage of
hemoglobin in cells of red blood which are covered in sugar. Normal
values are 4% to 6%. Levels for prediabetes are 6% to 6.5%. Levels of
6.5% and higher indicates diabetes.
Variations of Normal
There are several factors which can slant the results of any of the
above tests. Several of these factors include age, sex, general health,
race, medications, as well as if individual drinks alcohol. Menstrual
cycles of women in pre-menopause can also slant these tests.
Dangerous Blood Sugar Levels
When diabetes is not treated properly and other even when it is
treated proper, there are dangerous risks of blood sugar levels. There
are 2 involving hypoglycemia where blood sugar is too low and
hyperglycemia where blood sugar is too high.
Hypoglycemia
When hypoglycemia occurs the level of blood sugar has dropped lower
than 70 and often happens because of missing a meal, missing a snack, or
by failing to eat enough carbohydrates. Exercise when it is strenuous
or an illness can also cause hypoglycemia.
Signs of hypoglycemia can include jitters, pale skin, headache, and
extreme hunger, changes in mood or behavior, dizziness, trouble paying
attention or tingling around mouth.
To treat blood sugar which is too low the individual needs to eat
carbohydrates to up the level. This can be done by drinking about
one-half a cup of soft drink, juice, eating glucose tablets or any hard
candy. Then the glucose level needs to be checked in 15 minutes. If
the level is still too low, the process needs to be repeated every 15
minutes until the proper level is maintained.
Hyperglycemia
The other dangerous level is hyperglycemia which happens when glucose
levels rise to 200 – 240 or above. When glucose levels keep on
climbing it becomes a problem. It can happen because of eating a meal
which is too large, or the meal had too many carbohydrates, stress or
not having any exercise as well as being ill can cause high levels.
The signs of hyperglycemia consist of increased urination or
excessive thirst. At levels over 240 or higher, the risk of diabetic
coma exists. This is also known as ketoacidosis.
Ketoacidosis can occur because the body does not have enough insulin
to breakdown glucose and therefore the body begins to use fat for
energy. This process causes the development of ketones which the body
can not tolerate. Ketones are dumped in the urine which is the body’s
effort to get rid of these excessive ketones. But the body can not
release all the ketones and as they build up in the blood system, they
create the condition of ketoacidosis which leads to diabetic coma and
even death.
To treat this condition is to first determine if ketones are present
in the urine. If no ketones are found in the urine, then immediate
exercise will lower the blood sugar level. Exercise with ketones in the
urine has the opposite effect and will raise the blood sugar higher.
If hyperglycemia is happening too frequently, the individual needs to
seek a physician’s counsel as there may need to be adjustments in
medication in order to maintain a healthy level.
