Which Carbs Raise Blood Sugar Levels
In plant foods, carbs comprise a combination of starch, sugar, and fiber. Only the starch and sugar components raise blood sugar.
Fiber thats naturally found in foods, whether soluble or insoluble, doesnt break down into glucose in the body, and doesnt raise blood sugar levels .
You can actually subtract the fiber and sugar alcohols from the total carb content, leaving you with the digestible or net carb content. For example, 1 cup of cauliflower contains 5 grams of carbs, 3 of which are fiber. Therefore, its net carb content is 2 grams.
Prebiotic fiber, such as inulin, has even been shown to improve fasting blood sugar and other health markers in people with type 2 diabetes .
Sugar alcohols, such as maltitol, xylitol, erythritol, and sorbitol, are often used to sweeten sugar-free candy and other diet products.
Some of them, especially maltitol, can actually raise blood sugar levels in people with diabetes .
For this reason, use the net carb tool cautiously, as the count listed on a products label may not be accurate if all the carbs contributed by maltitol are subtracted from the total.
Furthermore, the net carb tool isnt used by the Food and Drug Administration or the ADA.
This carb counter may be a valuable resource. It provides data for hundreds of foods on total carbs, net carbs, fiber, protein and fat.
Summary
Starches and sugars raise blood sugar levels, but dietary fiber does not. The sugar alcohol maltitol may also raise blood sugar.

Exercise helps improve blood glucose in people with type 2 diabetes by increasing insulin sensitivity and the bodys ability to use glucose as energy, according to the American Diabetes Association. In type 2, exercise helps improve insulin resistance, says James G. Beckerman, MD, a cardiologist in Portland, Oregon. The end result is lower blood sugars.
Crandall Snyder tells patients that exercise is like spring cleaning for the body. It takes the stored form of glucose and uses it for energy so the next time you eat carbohydrates there’s a place to put it, she says.
Because exercise can immediately reduce blood sugar levels in people with type 2 diabetes, work with your healthcare team to determine the right amount of activity and timing for you. A study published in September 2017 in Frontiers in Endocrinology found exercising 30 minutes after the start of a meal is usually best for maintaining blood sugar controls.

What Are The Symptoms Of Hypoglycemia
Symptoms of hypoglycemia can start quickly, with people experiencing them in different ways. The signs of hypoglycemia are unpleasant. But they provide good warnings that you should take action before blood sugar drops more. The signs include:
- Shaking or trembling.
- Tingling or numbness in the face or mouth.
During a severe hypoglycemic event, a person may:
- Be unable to eat or drink.
- Have a seizure or convulsions .
- Lose consciousness.
- Slip into a coma or die .

Go For Whole Fruit Over Juice
A glass of orange juice is not the same as eating a whole orange. “People generally drink more juice and therefore consume more calories and sugar than they would by just eating fruit,” says Wylie-Rosett. Plus, you get more fiber from the whole fruit. For instance, there’s about 4 grams in a large orange, compared to less than 1 gram in 8 ounces of juice. A small amount of juice is OK, but it shouldn’t be your go-to beverage, she says. When you do drink it, make sure you’re serving it up in an actual juice glass rather than a large cup.
When To Contact Your Doctor

Hyperglycemia can turn into a medical emergency like DKA and HHS that requires immediate intervention by your doctor or a local emergency department. If you have two blood sugar readings of 300 mg/dL or more, or have blood sugar above your target range for more than a week, seek immediate medical help.
Signs of hyperglycemia include:
- Stomach pain, nausea, or vomiting
- Shortness of breath

Ensure A Good Nights Sleep
Never underestimate the power of a good nights sleep. A single night of inadequate sleep makes our body react in a manner similar to insulin resistance. It can lead to raised blood sugar levels. A good nights sleep can improve glucose metabolism. It will also keep you motivated to follow through with your diet and exercise routine.
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.

Only You Can Prevent Blood Sugar Spikes
Its annoying but true: The best way to lower your blood sugar is to avoid a spike in the first place.
Eating whole foods that are low in sugar and exercising regularly will help keep your blood sugar in check. This can be beneficial for people with type 2 diabetes, but medications may also be necessary to keep blood sugar in a healthy range.
To avoid food-based spikes, try to steer clear of added sugars in your diet. The FDA recommends consuming less than 200 calories a day from added sugars.
That sounds pretty simple, but when you realize that 16 ounces of orange juice has 240 calories , its easy to see how sugar consumption gets out of hand.
Its best to avoid all sugary drinks and check the labels. There are hidden sugars in everything from bread to turkey slices, so double-check your favorite foods to make sure you arent getting any unnecessary sweetness.

Eat The Right Carbohydrates
There are
Sugars and starches raise blood sugar levels, but fiber does not cause a blood sugar spike, as the body is unable to absorb and break down this type of carb. As such, people may consider including carbs that are richer in fiber in their diet.
People may also refer to sugars and starches as simple and complex carbs. Simple carbs primarily consist of one type of sugar. The body breaks these carbohydrates down very quickly, which causes blood sugar to rise rapidly. Complex carbohydrates consist of three or more sugars that are linked together. They result in a more gradual release of sugar into the body, meaning that blood sugar levels do not rise rapidly after a person eats them.
Some people may use the glycemic index to help them monitor how much sugar and carbohydrate they eat, which will, in turn, help them manage their blood sugar levels. The GI measures and ranks various foods by how much they cause blood sugar levels to rise.
Evidence notes a link between obesity and type 2 diabetes. Research also highlights the relationship between obesity and insulin resistance. Insulin is the hormone that is responsible for allowing glucose in the blood to enter cells. Losing 510% of body weight can help those with excess weight improve their blood sugar levels.
What Symptoms To Watch For
Hypoglycemia can be a challenging diabetes compications, as you ask yourself, why does my sugar keep dropping? There are several common low blood sugar symptoms to look out for. These symptoms arise due to the adrenal glands releasing both epinephrine and cortisol in response to hypoglycemia.
However, not everyone will experience all of thesehypoglycemia symptoms , and low blood sugar reactions can change. If you suspect you have low blood sugar, the best thing to do is check your blood sugar to confirm.
People who have had diabetes for a long time or who have experienced hypoglycemia frequently may develop hypoglycemia unawareness.
Hypoglycemia unawareness is a diabetes complication where people dont experience the usual warning signs of low blood sugar before it occurs. Up to 40% of people with type 1 diabetes experience hypoglycemia unawareness.

What Should Your Blood Sugar Be When You Wake Up
Whenever possible, aim to keep your glucose levels in range between 70 and 130 mg/dL in the morning before you eat breakfast, and between 70 and 180 mg/dL at other times. For some people, including older adults or pregnant women, a slightly looser or tighter glucose range might be best, and you should discuss with your healthcare provider what your goals may be.
Managing your glucose levels is key to preventing short and long-term complications. Though the occasional high blood glucose wont put you in immediate danger consistently high glucose levels over a long period of time are associated with complications of diabetes such as heart disease and stroke, chronic kidney disease, nerve damage, eye disease and more.
Additionally, high glucose levels especially in people with type 1 diabetes can put you in immediate danger. These high levels, if combined with high blood ketone levels, can cause diabetic ketoacidosis , a potentially life-threatening condition that occurs when a person has high blood ketones and not enough insulin. Symptoms of DKA include shortness of breath, fruity-smelling breath, nausea and vomiting, confusion, or loss of consciousness.
What Can Cause Low Blood Sugar Levels

Some things that can make low blood sugar levels more likely are:
- skipping meals and snacks
- not eating enough food during a meal or snack
- exercising longer or harder than usual without eating some extra food
- getting too much insulin
- not timing the insulin doses properly with meals, snacks, and exercise
Also, some things may increase how quickly insulin gets absorbed into the bloodstream and can make hypoglycemia more likely. These include:
- taking a hot shower or bath right after having an insulin injection increases blood flow through the blood vessels in the skin, which can make the insulin be absorbed more quickly than usual
- injecting the shot into a muscle instead of the fatty layer under the skin
- injecting the insulin into a part of the body used a lot in a particular sport .
All of these situations increase the chances that a person may get hypoglycemia.

A Low Blood Sugar Level Without Diabetes
A low blood sugar level is uncommon in people who do not have diabetes.
Possible causes include:
- a gastric bypass
- other medical conditions, such as problems with your hormone levels, pancreas, liver, kidneys, adrenal glands or heart
- some medicines, including quinine
See a GP if you think you keep getting symptoms of a low blood sugar level. They can arrange some simple tests to check if your blood sugar level is low and try to find out what’s causing it.
Treating Severely Low Blood Sugar
Blood sugar below 55 mg/dL is considered severely low. You wont be able to treat it using the 15-15 rule. You also may not be able to check your own blood sugar or treat it by yourself, depending on your symptoms. Make sure your family members, friends, and caregivers know your signs of low blood sugar so they can help treat it if needed.
Injectable glucagon is the best way to treat severely low blood sugar. A glucagon kit is available by prescription. Speak with your doctor to see if you should have a kit. Be sure to learn how and when to use it. Let family members and others close to you know where you keep the glucagon kit and make sure theyve been trained in how to use it too.
Its important to contact a doctor for emergency medical treatment immediately after receiving a glucagon injection. If a person faints due to severely low blood sugar, theyll usually wake up within 15 minutes after a glucagon injection. If they dont wake up within 15 minutes after the injection, they should receive one more dose. When the person is awake and able to swallow:
- Feed the person a fast-acting source of sugar .
- Then, have them eat a long-acting source of sugar .
Its also important that friends, family, co-workers, teachers, coaches, and other people you may be around often know how to test your blood sugar and treat severely low blood sugar before it happens.
If any of the following happens, your friend, relative, or helper should call 911:

When To Go To The Er
High blood sugar can be very concerning because your body can start burning fat for energy instead of blood glucose.
This can cause conditions such as DKA and hyperglycemic hyperosmolar syndrome . These conditions are medical emergencies and can be fatal if left untreated.
DKA is a serious complication of type 1 diabetes. Its rare in people with type 2 diabetes, but can occur.
Symptoms that can indicate you should go to the emergency room include:
- ketones in your urine, as diagnosed using a urine dipstick test
High blood sugar levels can cause a fluid imbalance in the body and can cause the blood to become acidic in a manner that doesnt support life.
Medical treatments for these conditions include administering intravenous insulin on a continuous basis and IV fluids to correct dehydration.
Summary
High blood sugar can become a medical emergency. Go to the ER if you suspect DKA or HHS.
How Can I Check My Blood Sugar
Use a blood sugar meter or a continuous glucose monitor to check your blood sugar. A blood sugar meter measures the amount of sugar in a small sample of blood, usually from your fingertip. A CGM uses a sensor inserted under the skin to measure your blood sugar every few minutes. If you use a CGM, youll still need to test daily with a blood sugar meter to make sure your CGM readings are accurate.
