What Are Clinical Trials For Low Blood Glucose
Clinical trialsand other types of clinical studiesare part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.
Researchers are studying many aspects of low blood glucose levels in diabetes, such as
- how to diagnose and treat low blood glucose among people with diabetes
- medicines that can treat symptoms of low blood glucose in people with hypoglycemia unawareness
- educational approaches to reduce fear of low blood glucose, which can make it harder for you to control your diabetes
Carbohydrates And Blood Sugar
When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood.
- As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage.
- As cells absorb blood sugar, levels in the bloodstream begin to fall.
- When this happens, the pancreas start making glucagon, a hormone that signals the liver to start releasing stored sugar.
- This interplay of insulin and glucagon ensure that cells throughout the body, and especially in the brain, have a steady supply of blood sugar.
Carbohydrate metabolism is important in the development of type 2 diabetes, which occurs when the body cant make enough insulin or cant properly use the insulin it makes.
- Type 2 diabetes usually develops gradually over a number of years, beginning when muscle and other cells stop responding to insulin. This condition, known as insulin resistance, causes blood sugar and insulin levels to stay high long after eating. Over time, the heavy demands made on the insulin-making cells wears them out, and insulin production eventually stops.
What Is Low Blood Glucose
Low blood glucose, also called low blood sugar or hypoglycemia, occurs when the level of glucose in your blood drops below what is healthy for you. For many people with diabetes, this means a blood glucose reading lower than 70 milligrams per deciliter .1 Your number might be different, so check with your doctor or health care team to find out what blood glucose level is low for you.

What To Eat To Manage Blood Sugar Levels At Night
If you have diabetes, there are several reasons why your blood sugar may be high during the night â and therefore high the next morning. The most common causes are eating too many carbohydrates at bedtime and not taking enough diabetes medication, according to the Cleveland Clinic.

But morning hyperglycemia can have other causes, including the Somogyi effect, sometimes called rebound hyperglycemia. Managing this effect often requires eating a small evening snack to keep blood sugar levels stable throughout the night.
How To Raise Blood Sugar
For optimal body function it is necessary to maintain a certain blood sugar level, when the blood sugar levels drops below the cut off point of 3.35 mmol/l the condition is known as hypoglycaemia or low blood sugar level.
Hypoglycaemia mainly occurs in people with glucose metabolism defects and can lead to dizziness, sweating, tremor, hunger, loss of energy and other symptoms. If you suffer from hypoglycaemia you need to know how to raise your blood sugar levels in case they drop.
Glucose acts as the main fuel for the body and all the food consumed is eventually converted into glucose. Insulin helps to convert glucose into energy. Carbohydrates, fruit, vegetables, juices and sweets are instant sources of glucose.

Checking For Low Blood Sugar Levels
The warning signs of hypoglycemia are the body’s natural response to low blood sugar levels. When blood sugar levels fall too low, the body releases the hormone adrenaline, which helps get stored glucose into the bloodstream quickly. This can make someone:
- start shaking
- have an increased heart rate
If the hypoglycemia isn’t treated, more serious symptoms may happen, such as drowsiness, confusion, seizures, and loss of consciousness.
The only way to know for sure if you’re having a low blood sugar level is to test. Blood sugar levels can be tested with a . This computerized device measures and displays the amount of glucose in a blood sample. But if you can’t quickly check your blood sugar level, it’s important to treat yourself for hypoglycemia immediately to prevent symptoms from getting worse.
Sometimes a person with diabetes may have symptoms of low blood sugar levels, but blood sugar levels are not actually low. This is a called a false reaction. The hormone adrenaline is not just released when blood sugar drops too low it’s also released when blood sugar levels fall quickly when they’re too high. If you’re having a false reaction, you might actually have blood sugar levels in a healthy range but feel as if you have low blood sugar. Testing blood sugar levels before treating yourself for hypoglycemia can help you figure out if you’re having a false reaction.
What Are The Complications Of Low Blood Glucose
Mild-to-moderate low blood glucose can be easily treated. But severely low blood glucose can cause serious complications, including passing out, coma, or death.
Repeated episodes of low blood glucose can lead to
- high blood glucose levels, if worry or fear of low blood glucose keeps you from taking the medicines you need to manage your diabetes8
- hypoglycemia unawareness, a condition in which you dont notice any symptoms of low blood glucose until your blood glucose level has dropped very low

How Do I Detect Spikes In My Sugar Levels
The exact timing of blood sugar spikes can vary from person to person and meal to meal. However, on average, the post-meal peaks tend to be about one hour and 15 minutes after starting a meal.
The best way to measure post-meal patterns is by using a continuous glucose monitor or Flash monitors. These devices can give you a clear view, including graphs, of what happens with the glucose levels after meals without the need for finger pricking . You can ask your diabetes health team if they are available for you as they are not available to everybody.
If you are not using a CGM, then please speak to your healthcare team about the best way to do this for you with finger prick testing.
How do I know it is a spike?
There is no universal answer or specific guidelines on when a sugar level is too high after meals. However, if post-meal readings are consistently above your target range , then you should discuss whether it would be beneficial for you to address these spikes and how to do this, with your healthcare team .
If you are reviewing your post-breakfast sugar levels, you should also be aware of changes in your hormones in the morning, which cause increases in sugar levels . This Digibete video may help.
Some ways to reduce blood sugar spikes after meals
1. Choose low glycaemic index foods
When blood sugar levels are low or hypoglycaemic we need high glycaemic index foods , such as dextrose tablets or juice, that are absorbed quickly to raise our levels and to treat the hypo.
High Calorie Foods May Or May Not Cause The Blood Sugar Level To Rise
Many people think that all high-calorie foods raise blood sugar level, but this is not always the case.
In general, foods that cause blood sugar level to rise the most are those that are high in carbohydrates, which are quickly converted into energy, such as rice, bread, fruits and sugar. Next are foods high in protein, such as meats, fish eggs, milk and dairy products, and oily foods. However, even though carbohydrates affect blood sugar levels, if you don’t eat them your diet will be unbalanced and you won’t feel satisfied after your meal, which can lead to excessive consumption of foods rich in protein and fat.

What Is The A1c Test
The A1C test is a simple blood test that measures your average blood sugar levels over the past 2 or 3 months. The test is done at a lab or your doctors office in addition tonot instead ofregular blood sugar testing you do yourself.
A1C testing is part of the ABCs of diabetesimportant steps you can take to prevent or delay health complications down the road:
- A: Get a regular A1C test.
- B: Try to keep your blood pressure below 140/90 mm Hg .
- C: Manage your cholesterol levels.
- s: Stop smoking or dont start.
The A1C goal for most adults with diabetes is between 7% and 8%, but your goal may be different depending on your age, other health conditions, medicines youre taking, and other factors. Work with your doctor to establish a personal A1C goal for you.
Blood Sugar Level Rises Every Time You Eat
Your blood sugar level rises immediately after eating a meal or snack . In a healthy person, insulin then starts working, and the blood sugar level returns to the pre-meal level 2 hours after eating. In untreated diabetes patients, the blood sugar level does not return to the pre-meal level of its own accord. Some people’s blood sugar level remains high two hours after eating, even though on an empty stomach it would be at a normal level. As a result, the risk of developing diabetes increases as insulin is not properly secreted, or does not work properly in the body. In order to make sure insulin works properly, it is important not to overeat and to avoid becoming obese. Knowing which foods will not cause a sudden and extreme spike in blood sugar level and using this knowledge in your daily life will help you to prevent obesity and diabetes, and maintain good health.

Whats Considered Low Blood Sugar
Your blood sugar tends to fluctuate throughout the day. Itll be lower when you first wake up, especially if you havent eaten for the past 8 to 10 hours.
Your blood sugar will go up once you eat. Depending on when you last ate, heres whats considered to be a normal blood sugar range:
|Fasting||2 hours after a meal|
|7099 mg/dL||Less than 140 mg/dL|
Low blood sugar, also known as hypoglycemia, is when your blood sugar levels fall below 70 mg/dL.
The point at which low blood sugar symptoms become noticeable is different from one person to the next.
Some people may feel jittery, irritable, or lightheaded when their blood sugar level falls to 70 mg/dL. Other people may not feel any symptoms until well below that mark.
A quick, simple blood test can measure your blood sugar level. If you have diabetes or another medical condition that sometimes causes episodes of low blood sugar, its important to regularly check your blood sugar with a home test.
If a test shows that your blood sugar is below normal, you can take steps to adjust it quickly.
Symptoms of low blood sugar vary from person to person and can even be different from one episode to the next. You may experience specific symptoms the first time your blood sugar dips, and different symptoms the next time.
The most common mild to moderate symptoms of low blood sugar include:
- jitters or shaking
More severe symptoms of hypoglycemia include:
- inability to eat or drink
High Blood Sugar Level Causes
Several types of diabetes and medical conditions are the primary cause of high blood sugar levels. Most of which are unpreventable issues but are the reason for a spike in high blood sugar. The causes for high blood sugar levels are as follows:
Causes of low blood sugar levels are very different and are as important to be aware of, as they are in fact easier to control.

Stick With Starchy Vegetables
Cooked carrots, potatoes and sweet potatoes can boost your blood sugar. Raw carrots have a lower GI. Nonstarchy vegetables, such as leafy greens, eggplant, zucchini and cucumbers, are lower in carbs and have very little effect on your blood sugar levels. Fat slows digestion and makes your blood sugar levels rise less quickly, so potatoes cooked with fat, such as French fries and potato chips, have a lower GI than plain boiled, mashed and baked potatoes.
How Are Low Blood Sugar Levels Treated
Your diabetes health care team will give you guidelines for treating low blood sugar levels, depending on your symptoms. If you can, try to test your blood sugar levels to make sure that your symptoms are because of hypoglycemia. If you can’t test blood sugar immediately, don’t delay in treating your symptoms you can always check your blood sugar after you’ve taken steps to get your blood sugar back up into the normal range.
When blood sugar levels are low, the goal is to get them back up quickly. To do that, you should take in sugar or sugary foods, which raise the blood sugar level quickly. Your health care team might suggest that you:
- Eat, drink, or take something that contains sugar that can get into the blood quickly. Your doctor may tell you to have really sugary foods or drinks or might give you glucose tablets or gel to take all of these can help to raise your blood sugar level fast, which is what you need to do when it’s low.
- Wait about 10 minutes to let the sugar work.
- Recheck your blood sugar level with a glucose meter to see if blood sugar levels are back to normal.
- Get a glucagon shot , if your symptoms are severe or get worse after you eat, drink, or take glucose.
Sometimes, blood sugar levels can get so low that you may not be awake enough to eat or drink something to get them back up. When this happens, you may need a glucagon shot.

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.

When To See A Doctor
According to the University of Michigan, blood sugar levels of 300 mg/dL or more can be dangerous. They recommend calling a doctor if you have two readings in a row of 300 or more.
See your doctor if you have consistently high blood sugar levels. Symptoms of this include:
- increased thirst
- high levels of sugar in urine
Ask your doctor how often to check your blood sugar and about your ideal blood sugar levels.
If you dont currently see a doctor who specializes in diabetes, known as an endocrinologist, you can find one by searching the American Association of Clinical Endocrinologists website.
You can find a certified diabetes educator by visiting the American Diabetes Associations website and searching by zip code.
Talk to your doctor if you have consistently high blood sugar readings or symptoms of chronic hyperglycemia.
Checking your blood sugar and then treating hyperglycemia early will help prevent any complications.
Health problems can arise when someone has high blood sugar regularly and without treatment.
Examples of complications include:
- nerve damage, called diabetic neuropathy, that may affect sensations in the feet and hands
- diabetic retinopathy, or damage to the blood vessels in the eyes that affects vision
- increased risks for kidney problems
- increased risks for heart problems
Taking steps to keep your blood sugar at target levels can help to minimize the likelihood that these complications will occur.
Low Blood Sugar After Exercise
When you exercise, your body pulls sugar from your bloodstream to fuel the activity. It also draws on sugar stored as glycogen in your muscles and liver.
This is why your blood sugar level tends to drop during a workout. Its common for blood sugar to continue to drop for several hours after exercise, too.
If your blood sugar level drops to 70 mg/dL or lower, its known as low blood sugar, or hypoglycemia. In most cases, hypoglycemia can be treated by eating or drinking fast-acting carbohydrates. In severe cases, hypoglycemia must be treated with a medication known as glucagon.
