What Happens If Blood Sugar Level Is Too High
If your blood sugar levels are too high then you risk developing diabetes. You can develop cardiovascular disease and nerve damage. With diabetes, the glucose in your blood does not reach your cells and can lead to these and other complications. Adding exercise and eating healthy can help to control your diabetes and prevent secondary diseases.
You may develop diseases and disabilities in the future, such as cardiovascular disease and nerve damage, if you have diabetes.

Optimal Blood Sugar And Ketone Levels For Ketosis
Unless you are managing a chronic condition that may benefit from elevated ketone levels , you could potentially save a lot of money and angst by focusing on keeping your blood sugars closer to optimal and not worry about your blood ketone levels.
In line with oxidative priority, the glucose in your blood needs to be burned before the fat in your diet and the fat in your body. If your glucose stores are constantly overfull, you will be stuck burning glucose, and you will not get to use your body fat.
How To Check Your Own Blood Sugar Level
One way to check ones own sugar level is by pricking a finger with a lancet and placing the blood that comes out onto a test strip, then inserting the strip into a glucose monitor. A meter can tell you what your levels are in about 5 seconds. Another option is by taking an oral glucose tolerance test , which takes longer but may also provide more accurate results. A persons individual level will depend on many factors including how old they are, their ethnicity, their weight and height, and the activity theyve performed recently. Blood sugar levels can be checked by pricking a finger to get a drop of blood and putting it on a glucose meter.

Choose Different Carbs Before Exercise
If you experience low blood sugar levels during exercise, you may need to take some additional sugars. You will need around 30g of sugar per hour of endurance exercise. This is equivalent to 1 cup of apple juice which is quick to enter the blood stream, providing pretty instant energy for your physical activity.

How To Diagnose Blood Sugar Level
Its possible to check your glucose level without a glucose meter by pricking your finger with a clean needle and putting the drop of blood on a strip that has been dipped in a special liquid. The strip will show your blood sugar level in both mg/dL and mmol/L.
A fasting blood glucose level is the amount of glucose in a persons blood after they have not eaten for about 8 hours. The level is usually around 100 milligrams per deciliter . Its possible to measure it using a glucose meter. 80-99 mg/dL is the right amount of sugar to be present in the blood.
Feeling Irritable Anxious Or Moody
Feelings of anxiety, irritability or mood swings may come and go as a result of not enough insulin entering the brain. Insulin takes the happy hormone – serotonin – into the brain where it balances our mood and helps to relieve anxiety. If your brain isn’t receiving serotonin via insulin, it can leave you feeling irritable, anxious and moody. You might enjoy our nutritionists blog ‘What supplements to take for brain health‘.

The Effects Of Low Blood Sugar On Your Body
Every cell in your body needs energy to function. The main source of energy might come as a surprise: Its sugar, also known as glucose. Blood sugar is essential to proper brain, heart, and digestive function. It even helps keep your skin and vision healthy.
When your blood sugar levels fall below the normal range, its called hypoglycemia. There are many identifiable symptoms of low blood sugar, but the only way to know if you have low blood sugar is by taking a blood glucose test.
Learn more about the symptoms of low blood sugar, as well as the long-term effects on the body.
most common reasons for low blood sugar are some medications used to treat diabetes, such as insulin.
In type 1 diabetes, the pancreas can no longer produce insulin. In type 2 diabetes, the pancreas doesnt make enough insulin, or your body cant use it properly. Too much insulin or oral diabetic medication can lower the blood sugar level, leading to hypoglycemia.
However, contrary to popular belief, low blood sugar isnt exclusive to diabetes, though it is rare. It can also happen if your body makes more insulin than it should.
Another possible cause of low blood sugar is drinking too much alcohol, especially over long periods of time. This can interfere with the livers ability to create a buildup of glucose and then release it into your bloodstream when you need it.
Other causes include:
The Dangers Of Low Blood Glucose
At some time, most people with diabetes experience the sweating and shakiness that occurs when blood glucose levels fall below 70 mg/dl a condition known as hypoglycemia. The average person with type 1 diabetes may experience symptoms of low blood glucose up to two times a week. However, not all are aware that these symptoms can rapidly progress to seizures, coma and even death if hypoglycemia is severe. Though hypoglycemia can be common and occur repeatedly in some people with diabetes, symptoms of low blood glucose should always be taken seriously. People with diabetes and their families, friends or coworkers should be prepared to act quickly and responsibly at the earliest signs of low blood glucose.

Causes Of Blood Sugar Levels
Whilst the liver and muscles produce some glucose, most comes from the foods we eat. Food and drinks that are high in carbohydrates are most impactful on blood sugar level. What we eat provides us most of the nutrients our body needs and sometimes, does not need. That is not to say that food is a major cause of blood sugar level increasing or decreasing too dramatically.
Typically, if a person has health conditions or poor nutrition, this will lead to a spike or decline in blood sugar level. The causes differ from high to low blood sugar levels and are as follows:
What Causes A Low Blood Sugar Level
In people with diabetes, the main causes of a low blood sugar level are:
- the effects of medicine especially taking too much insulin, medicines called sulfonylureas , medicines called glinides , or some antiviral medicines to treat hepatitis C
- skipping or delaying a meal
- not eating enough carbohydrate foods in your last meal, such as bread, cereals, pasta, potatoes and fruit
- exercise, especially if it’s intense or unplanned
- drinking alcohol
Sometimes there’s no obvious reason why a low blood sugar level happens.
Very occasionally, it can happen in people who do not have diabetes.

Preventing Low Blood Sugar Levels
Here are some other tips to help you avoid low blood sugar levels:
- Eat all your meals and snacks on time and try not to skip any.
- Take the right amount of insulin.
- If you exercise longer or harder than usual, have an extra snack.
- Don’t take a hot bath or shower right after an insulin shot.
- Stick to your diabetes management plan.
- Check your blood sugar levels regularly, so you can tell if your blood sugars are running too low and your treatment plan needs adjustment.
- Carry something containing sugar with you at all times and take it right away if you have symptoms. Don’t wait to see if the symptoms will go away they may get worse!
Alcohol and drugs can cause major problems with your blood sugar levels, so avoiding them is another way to prevent diabetes problems. Drinking can be particularly dangerous even deadly for people with diabetes because it messes up the body’s ability to keep blood glucose in a normal range. This can cause a very rapid drop in blood glucose in people with diabetes. Drug or alcohol use is also dangerous because it may affect someone’s ability to sense low blood sugar levels.
Learning how to recognize the signs of low blood sugar levels and get them back to normal is an important part of caring for diabetes. Keeping track of your blood sugar levels and recording lows when they occur will help you and your diabetes health care team keep your blood sugar levels in a healthy range.

Treating An Episode Of Hypoglycaemia
The immediate treatment for hypoglycaemia is to have some sugary food or drink to end the attack.
For example, this could be:
- a glass of fruit juice or non-diet soft drink
- between three and five dextrose tablets
- a handful of sweets
At first you should avoid fatty foods and drinks, such as chocolate and milk, because they don’t usually contain as much sugar and the sugar they do contain may be absorbed more slowly.
After having something sugary, you should have a longer-acting carbohydrate food, such as a few biscuits, a cereal bar, a piece of fruit or a sandwich.
It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. If it’s still too low , you should have some more sugary food or a drink before testing your levels again in another 15 to 20 minutes.
When treating someone else with hypoglycaemia, if the above treatment isn’t effective, you may be able to help them by applying glucose gel to the inside of their cheeks, and gently massaging the outside of their cheeks.
It may take 10 to 15 minutes before they feel better. This shouldn’t be done if the person is drowsy or unconscious because of the risk of choking.
How Do I Treat Hypoglycemia
A mild case of hypoglycemia can be treated through eating or drinking 15-20g of fast acting carbohydrate such as glucose tablets, sweets, sugary fizzy drinks or fruit juice.
Some people with diabetes may also need to take 15-20g of slower acting carbohydrate if the next meal is not due.
A blood test should be taken after 15-20 minutes to check whether blood glucose levels have recovered. Severe hypoglycemia may require an ambulance, for example if loss of consciousness occurs or a seizure persists for more than 5 minutes.
Severe hypos can be treated with glucagon if a glucagon injection kit is available and in date.

Evolution And Species Distribution
Insulin may have originated more than a billion years ago. The molecular origins of insulin go at least as far back as the simplest unicellular . Apart from animals, insulin-like proteins are also known to exist in the Fungi and Protista kingdoms.
Insulin is produced by of the in most vertebrates and by the in some . and , venomous sea snails that hunt small fish, use modified forms of insulin in their venom cocktails. The insulin toxin, closer in structure to fishes’ than to snails’ native insulin, slows down the prey fishes by lowering their blood glucose levels.
Treatment By Family Friends Or Co
Family, friends, and co-workers of those with hypoglycemia are often first to identify hypoglycemic episodes, and may offer help. Upon recognizing the signs and symptoms of hypoglycemia in a diabetic, a blood sugar level should first be measured using a glucose meter. If blood glucose is below 70 mg/dL , treatment will depend on whether the person is conscious and can swallow safely. If the person is conscious and able to swallow, the family, friend, or co-worker can help the hypoglycemic consume 10-20 grams of a carbohydrate to raise blood glucose levels to a minimum of 70 mg/dL . Improvement in blood sugar level and symptoms is expected to occur in 1520 minutes, at which point blood sugar is measured again. If the repeat blood sugar level is not above 70 mg/dL , the hypoglycemic should consume another 10-20 grams of a carbohydrate and with remeasurement of blood sugar levels after 1520 minutes. Repeat until blood glucose levels have returned to normal levels, or call emergency services for further assistance.
If the person is unconscious, a glucagon kit may be used to treat severe hypoglycemia, which delivers glucagon either by injection into a muscle or through nasal inhalation. In the United States, glucacon kits are available by prescription for diabetic patients to carry in case of an episode of severe hypoglycemia. Emergency services should be called for further assistance.

How Do I Prepare For The Plasma Glucose Level Test And How Are The Results Interpreted
To get an accurate plasma glucose level, you must have fasted for at least 8 hours prior to the test. When you report to the clinic or laboratory, a small sample of blood will be taken from a vein in your arm. According to the practice recommendations of the American Diabetes Association, the results of the blood test are interpreted as follows:
Fasting blood glucose level
- If your blood glucose level is 70 to 99* mg/dL . . .
- What it means: Your glucose level is within the normal range
*Values between 50 and 70 are often seen in healthy people
**The condition of “prediabetes” puts you at risk for developing Type 2 diabetes, high blood pressure, and blood lipid disorders

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:
- Heart attack
- 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:
