Microvascular Damage Of Eyes Kidneys Toes Etc
Microvascular damage is defined as damage to small blood vessels, and its a common consequence of high blood sugar. Evidence confirms that acute hyperglycemia causes microvascular damage and leads to poor functional recovery, especially in patients who have sustained myocardial infarction.
For example, numbers show that more than 661,000 Americans have kidney failure, but high blood pressure and diabetes are the most common risk factors for this serious health problem. Almost half of the patients with chronic kidney disease have diabetes. This isnt such a surprise if we bear in mind that poor glycemic control is associated with microvascular disease development.
High blood sugar damages nerves and interferes with their ability to send signals, which causes diabetic neuropathy. Damage of this kind usually affects eyes, kidneys, toes, and other parts of a patients body.
What Are Blood Sugar Levels
Blood sugar levels, also known as blood glucose level, is the level of sugar/glucose present in the blood. Glucose is a simple version of sugar which comes from the food we eat. Therefore, the more food you consume with high sugar levels over a period of time, will typically increase your blood sugar level.
Glucose comes from the foods we eat and its sugar content. When a person consumes a food with high sugar content, that is turned into glucose. The glucose is then absorbed into the bloodstream with the support of insulin. This is then distributed between the bodys cells and used as energy.
Foods high in glucose include most carbohydrates and a handful of proteins and fats. Most foods contain glucose as it is simply a natural sugar that occurs in most dietary forms. However, it is carbohydrates that contain the most sugar and 100% of it turns into glucose, through the process mentioned above, once consumed. The concentration of glucose present in the blood will determine your blood sugar level.
Here is a quick video explaining Blood sugar levels chart :
Your blood sugar level can either be low, normal or high. Depending on what you eat and health conditions, it will vary from person to person. Here is a breakdown of how your blood sugar works and how low or high blood sugar levels happens:
Prevent Type 2 Diabetes
If your test results show you have prediabetes, ask your doctor or nurse if there is a lifestyle change program offered through the CDC-led National Diabetes Prevention Program in your community. You can also search for an online or in-person program. Having prediabetes puts you at greater risk for developing type 2 diabetes, but participating in the program can lower your risk by as much as 58% .

For People Without Diabetes
For people who dont have diabetes, an A1c test result lower than 5.7% is considered normal. If your level is between 5.7% and 6.4%, you may have what is sometimes called . This means that you have higher than normal blood glucose but dont meet the criteria to be diagnosed with diabetes.
An FPG test result of 99 mg/dL or lower means that youre within a safe range. A result between 100 to 125 mg/dL is in the prediabetes range, and you might need follow-up testing. A safe range for an OGT test result is around 140 mg/dL 2 hours after the test starts, while 140 mg/dL to 199 mg/dL is considered a prediabetic range.
If results suggest that you have prediabetes, your provider might order more tests and offer ideas for that can help bring your blood glucose levels down. The goal is tolower your risk of developing type 2 diabetes later in life, or to delay its onset as long as possible.
A Rationale For Omitting Two
Get rights and content Objective: In making decisions regarding initiation of insulin therapy in gestational diabetes, most maternal-fetal obstetricians rely more on elevated fasting glucose values than on elevated 2-hour postprandial levels. We sought to determine whether the latter test is necessary. Study Design: From the patients with gestational diabetes mellitus managed over a 17-month period at Grady Memorial Hospital, we retrospectively analyzed data to determine whether normal fasting plasma glucose values predict elevated 2-hour postprandial values and whether the latter predict adverse outcome. Results: From 194 patients with gestational diabetes mellitus, 546 paired fasting and 2-hour postprandial glucose values were recorded. Fasting levels were normal in 467 in those, 2-hour levels were < 120 mg/dl in 83% and < 140 in fully 96%. In 131 women with all fasting plasma glucose values normal, the birth weights and the rates of cesarean delivery, shoulder dystocia, and macrosomia were similar, regardless of whether 2-hour postprandial glucose values were> 120. The actual cost of the 546 2-hour postprandial glucose tests was nearly $10,000. Conclusion: For metabolic surveillance in gestational diabetes mellitus, the 2-hour postprandial glucose test seems unnecessary, provided fasting plasma glucose values remain normal.Continue reading > >

Correcting High Blood Sugar Levels With Insulin
If you take insulin, one way to reduce blood sugar is to inject insulin.
However, be careful as insulin can take 4 hours or longer to be fully absorbed, so you need to make sure you take into account how much insulin you may already have in your body that is yet to be absorbed by the blood. Insulin that is yet to be absorbed by the blood is called active insulin.
If you decide to correct with insulin, watch you dont over correct as this can lead to hypoglycemia and can be dangerous, particularly so before bed.
High Blood Sugar During Pregnancy Effects On The Baby
High blood sugar during pregnancy is always a problem and can lead to miscarriages, abnormal baby birth and so on. The other possible effects on the baby are
- Stillbirth , this is high with poor blood sugar control.
- Birth defects, if youre diabetic then this complication is high, frequently visit the doctor during the primary trimester.
- Macrosomia, it is a condition where the baby is more than normal.
- Birth injury, this happens when the baby is large in size and it is difficult for delivery.
- Hypoglycemia, the baby is born with low glucose levels.
- Respiratory distress or trouble while breathing as the babys lungs arent grown properly due to high sugar level.
Preeclampsia, heart issues, brain and spinal problems, oral clefts, gastrointestinal and kidney defects, and limb problems are also common.

How Does Blood Sugar Level Work
With a lack of nutrients and food that contain glucose, the blood sugar level will begin to decline. This is known as hypoglycemia.
After blood sugar becomes low, the pancreas releases a peptide hormone called glucagon. When this happens, the glucose that is stored in the body for energy is instructed to release due to the liver. This causes the glucose to turn into glycogen, known as the glycogenesis process. This is what can help a body to regain energy as the readily stored glycogen, in the liver and muscles, will release into the body.
On the other hand, the blood sugar can also rise and become too high which is known as hyperglycemia.
When the body does not produce enough of the insulin hormone, blood sugar levels begin to increase. This is because glucose relies on the insulin hormone to help it absorb into the bloodstream. Usually, this occurs when the body cannot produce enough insulin, known as type 1 diabetes, or does not respond to insulin correctly, known as type 2 diabetes.
Eating too many processed foods can also cause your blood sugar level to rise. If there is not enough insulin present in the body, too much bad food can cause your blood sugar level to build up.
For those with a normal blood sugar level, this will be due to eating the right foods and your body being able to produce and respond to insulin.
You may be wondering what exactly causes an imbalance in blood sugar levels, so here is a roundup:
Manage Your Carb Intake
Your carb intake strongly influences your blood sugar levels .
Your body breaks carbs down into sugars, mainly glucose. Then, insulin helps your body use and store it for energy.
When you eat too many carbs or have insulin-function problems, this process fails, and blood glucose levels can rise.
Thats why the American Diabetes Association recommends that people with diabetes manage their carb intake by counting carbs and being aware of how many they need .
Some studies find that this can help you plan your meals appropriately, further improving blood sugar management (
Foods that are high in fiber include:
The recommended daily intake of fiber is about 25 grams for women and 35 grams for men. Thats about 14 grams for every 1,000 calories .
Eating plenty of fiber can aid blood sugar management. Soluble dietary fiber appears to be more effective than insoluble fiber for this purpose.

Surprising Things That Can Spike Your Blood Sugar
When you first found out you had diabetes, you tested your blood sugar often. Doing so helped you understand how food, activity, stress, and illness could affect your blood sugar levels. By now, youve got it figured out for the most part. But thenbam! Something makes your blood sugar zoom up. You try to adjust it with food or activity or insulin, and it dips really low. Youre on a roller coaster no one with diabetes wants to ride.
Do you know all these blood sugar triggers?
Knowledge is power! Look out for these surprising triggers that can send your blood sugar soaring:
Problems Caused By High Blood Sugar
It’s not usually a serious problem if your blood sugar is sometimes slightly high for a short time.
But high blood sugar can cause serious problems if it stays high for a long time or gets to a very high level.
It can lead to:
- life-threatening conditions such as diabetic ketoacidosis
If you have high blood sugar, your doctor or care team may ask you to test your blood or pee to check for ketones. A high level of ketones is a sign of diabetic ketoacidosis.

Consequences Of Blood Sugar Levels
Whilst most symptoms of low and high blood sugar levels are mild, they can worsen if left untreated and sometimes have long term consequences and/or complications. Overtime, a high blood sugar level is what can cause consequences. Lack of treatment can cause severe damage to the blood vessels and lead to complications such as:
- Damage to the eyes and/or loss of vision
- Nerve problems in the feet leading to infections
To avoid long term consequences and complications, it is advised to take all precautionary measures and treat your blood sugar level so that it can be maintained at your ideal reading. So do so, follow all treatment methods, stay on track with checking your level daily and seeking help if symptoms persist.
If you have any more questions, here are a few of the most frequently asked questions which may answer your concerns:
Different Levels And What They Mean
The ranges of safe levels of blood glucose depend on factors such as what time of day it is and when you last ate. Safe levels of blood sugar are high enough to supply your organs with the sugar they need, but low enough to prevent symptoms of hyperglycemia or complications of diabetes which follow the National Institute of Diabetes and Digestive and Kidney Diseases guides. Dangerous levels of blood glucose are outside of this range.
The target levels can also vary if you have diabetes. For example, if you are diabetic and are monitoring your blood sugar, you might get a reading of 65 mg/dl. That is considered to be mild hypoglycemia, and you would be wise to eat 15 grams of fast-acting carbohydrates and retest your blood sugar in 15 minutes.
If you were not diabetic, you probably would not know that your sugar was low because you would not test and because you would not symptoms, and you would not act.
That is fine because your body is capable, under normal circumstances, of raising your blood glucose to healthy levels when needed, even if you have not eaten. It is important to keep them in control to help prevent issues like heart disease or nerve damage.

How Is It Determined If The Dawn Phenomenon Or Somogyi Effect Is Causing The High Blood Sugar Levels
Your doctor will likely ask you to check your blood sugar levels between 2 a.m. and 3 a.m. for several nights in a row. If your blood sugar is consistently low during this time, the Somogyi effect is suspected. If the blood sugar is normal during this time period, the dawn phenomenon is more likely to be the cause.
Some additional clues that the Somogyi effect may be the cause include nightmares, restless sleep and overnight sweating as these are all signs of low blood sugar levels.
Make Physical Activity Part Of Your Daily Routine
Set a goal to be more physically active. Try to work up to 30 minutes or more of physical activity on most days of the week.
Brisk walking and swimming are good ways to move more. If you are not active now, ask your health care team about the types and amounts of physical activity that are right for you. Learn more about being physically active with diabetes.
Following your meal plan and being more active can help you stay at or get to a healthy weight. If you are overweight or obese, work with your health care team to create a weight-loss plan that is right for you.

What Are The Symptoms Of Hyperglycemia
Its especially important to know the early signs of hyperglycemia if you have type 1 diabetes. If hyperglycemia is left untreated in people with type 1 diabetes, it can develop into ketoacidosis, where ketones, which are toxic acids, build up in the blood. This condition is an emergency situation that can lead to coma or death.
Early symptoms of hyperglycemia include:
- High blood sugar.
- Unusual fruity smell on the breath.
- Deep labored breathing or hyperventilation.
- Rapid heartbeat.
What Do High Blood Glucose Results Mean
The most common reason why blood sugar climbs too high is a condition called diabetes . Diabetes is a serious condition that affects 1 in 10 Americans, and prediabetes affects 1 in 3 Americans. When you have diabetes, your body is either not producing enough insulin or not responding to insulin appropriately , causing glucose to build up in the blood. Prediabetes is a less severe form of diabetes that often leads to Type 2 diabetes if left untreated. The diagnosis of diabetes and prediabetes are often made by measuring the level of glucose in your blood.
Interpretation of your blood glucose results depends on when you completed blood work and what type of test was ordered by your doctor. The types of blood glucose tests and the numbers that might indicate diabetes and prediabetes are as follows:
- Finger stick glucose test: After a finger prick, blood is placed on small paper strip and blood sugar is measured on a handheld device
· Glucose 200 mg/dL may indicate diabetes
- Routine/random blood glucose test: Blood sample taken at any time, regardless of the last time you ate
· Glucose 200 mg/dL may indicate diabetes
- Fasting blood glucose test: Blood sample taken when you havent eaten for 8-12 hours, since your blood glucose levels are higher after youve eaten
· Glucose 126 mg/dL may indicate diabetes
· Glucose between 100-126 mg/dL may indicate prediabetes
· Glucose < 100 mg/dL is normal
· Interpretation varies depending on amount of sugar and wait period
