Normal Blood Sugar Levels Vs Hyperglycemia

How to Lower Blood Sugar Fast

If youve been diagnosed with diabetes, your endocrinologist will tell you what your target blood glucose levels are. Your levels may be different from what is usually considered as normal because of age, pregnancy, or other factors. You will be given two target levels, or ranges, one applying to when you haven’t eaten for a number of hours and one for after meals .

Early Symptoms Of Hyperglycemia

Early signs of high blood sugar, or hyperglycemia, may serve as a warning even before you test your blood glucose level. Typical high sugar symptoms may include:

  • Increased thirst and/or hunger
  • Fatigue
  • Sugar in your urine

It is important to recognize and treat hyperglycemia because if left untreated, it can lead to additional symptoms and complications, some of which are different for people with type 1 diabetes compared to type 2 diabetes. For example, people with type 1 diabetes are more likely to develop a severe condition resulting from high blood sugar called diabetic ketoacidosis. In addition to the common hyperglycemia symptoms listed above, symptoms of diabetic ketoacidosis include:

  • Heavy breathing
  • Abdominal pain

How Does Hyperglycemia Happen

Insulin is a hormone that lets your body use the sugar in your blood, which comes primarily from carbohydrates in the food that you eat. Hyperglycemia happens when your body has too little insulin to use the sugar in your blood.

People with type 1 diabetes can have episodes of hyperglycemia every day. Although this can be frustrating, it rarely creates a medical emergency. Not taking enough insulin can lead to hyperglycemia .

Other things that can cause hyperglycemia include:

  • Caffeine
  • Having trouble seeing or concentrating
  • Experiencing stomach pain, nausea, or vomiting
  • Having sweet-smelling or fruity breath
  • Cuts or sores that do not heal, infections, and unexplained weight loss may also be signs of long-term hyperglycemia.

If you notice any of these symptoms, you should check your blood sugar. If your blood sugar is very high, you should also test for ketones in either your blood or urine.

What Are Blood Sugar Targets

A blood sugar target is the range you try to reach as much as possible. These are typical targets:

  • Before a meal: 80 to 130 mg/dL.
  • Two hours after the start of a meal: Less than 180 mg/dL.

Your blood sugar targets may be different depending on your age, any additional health problems you have, and other factors. Be sure to talk to your health care team about which targets are best for you.

Correcting High Blood Sugar Levels With Insulin

How Do I Quickly Bring Down My Blood Glucose (Lower High ...

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.

What Causes High Morning Blood Sugars

Two main culprits prompt morning highs: the dawn phenomenon and waning insulin. A third, much rarer cause, known as the Somogyi effect, may also be to blame.

The occasional morning high will have little impact on your A1C, a measure of your average blood sugar levels over time that indicates how well managed your diabetes is. But if those highs become consistent, they could push your A1C up into dangerous territory.

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:

  • pale
  • 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.

How To Check Your Blood Sugar Levels

As Dr. Emanuele says, glucose monitoring can be an important tool to help you get your blood sugar under control. Typically, you would do it yourself using a glucose meter or glucometer, which analyzes a drop of blood that you draw by sticking your finger with a lancet and placing the blood on a disposable test strip that you insert into the meter. Your blood sugar goals are set by you and your doctor, but blood glucose for an adult without diabetes is below 100 mg/dl before meals and at fasting and less than 140 mg/dl two hours after a meal, notes the ADA.

Some people will check their blood sugar daily or multiple times a day, sometimes using a continuous monitor that is worn on the body particularly those who have type 1 diabetes or who have type 2 but take insulin. Yet how frequently a person should monitor their blood sugar is based on a number of factors, including but not limited to whether theyre on insulin, whether they’re taking oral medication, and how well their blood sugar is controlled and how old they are.

Meanwhile, keep an eye out for these nine key warning signs and symptoms that blood sugar is too high and talk to your doctor about whether you need to adjust your management plan.

What Causes Low Blood Sugar

How To Lower Blood Sugar Levels (Naturally & Quickly)

Low blood sugar has many causes, including missing a meal, taking too much insulin, taking other diabetes medicines, exercising more than normal, and drinking alcohol. Blood sugar below 70 mg/dL is considered low.

Signs of low blood sugar are different for everyone. Common symptoms include:

  • Shaking.
  • Dizziness.
  • Hunger.

Know what your individual symptoms are so you can catch low blood sugar early and treat it. If you think you may have low blood sugar, check it even if you dont have symptoms. Low blood sugar can be dangerous and should be treated as soon as possible.

Controlled Means Different Things To Different People

Theres no one-size-fits-all recommendation for blood sugar control.

The ADA says that a reasonable goal for many nonpregnant adults is to aim for an A1C level of less than 7. Yet some patients may be given a more stringent goal by their healthcare providers, such as 6.5, if thats reachable without harmful side effects, including hypoglycemia.

On the other hand, if you are elderly, managing other health complications, or reliant on insulin, you may be given less stringent goals. It really becomes more important to just keep in the same place, says Rahil Bandukwala, DO, an endocrinologist at MemorialCare Saddleback Medical Center in Laguna Hills, California. Keeping A1C between 7.5 and 8.5 may be very reasonable for such a patient, Dr. Bandukwala adds, echoing the ADAs recommendations.

Because elderly people are more likely to have blood sugar that swings too far downward, with fewer warning signs, managing their glucose too tightly can put them at greater risk for hypoglycemia, says Bandukwala. When you have low blood sugar, youre at a higher risk for becoming dizzy and falling or passing out, notes the ADA.

What Is Diabetic Ketoacidosis

If you think you may have low blood sugar, check it even if you dont have symptoms.

When too many ketones are produced too fast, they can build up in your body and cause diabetic ketoacidosis, or DKA. DKA is very serious and can cause a coma or even death. Common symptoms of DKA include:

  • Fast, deep breathing.
  • Nausea and vomiting.
  • Stomach pain.

If you think you may have DKA, test your urine for ketones. Follow the test kit directions, checking the color of the test strip against the color chart in the kit to see your ketone level. If your ketones are high, . DKA requires treatment in a hospital.

DKA happens most in people with type 1 diabetes and is sometimes the first sign of type 1 in people who havent yet been diagnosed. People with type 2 diabetes can also develop DKA, but its less common.

How Is It Treated

If you have diabetes and notice any of the early signs of high blood sugar, test your blood sugar and call the doctor. They may ask you for the results of several readings. They could recommend the following changes:

Drink more water. Water helps remove excess sugar from your blood through urine, and it helps you avoid dehydration.

Exercise more. Working out can help lower your blood sugar. But under certain conditions, it can make blood sugar go even higher. Ask your doctor what kind of exercise is right for you.

Caution: If you have type 1 diabetes and your blood sugar is high, you need to check your urine for ketones. When you have ketones, do NOT exercise. If you have type 2 diabetes and your blood sugar is high, you must also be sure that you have no ketones in your urine and that you are well-hydrated. Then your doctor might give you the OK to exercise with caution as long as you feel up to it.

Change your eating habits. You may need to meet with a dietitian to change the amount and types of foods you eat.

Switch medications. Your doctor may change the amount, timing, or type of diabetes medications you take. Donât make changes without talking to them first.

If you have type 1 diabetes and your blood sugar is more than 250 mg/dL, your doctor may want you to test your urine or blood for ketones.

Preventing Low Blood Sugar Levels

The 6 Best Ways to Test 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.

Causes Related To Diet

How to Lower Blood Sugar Level / 6 Powerful Tips for Diabetics

Processed foods and sugar

Diet and how it relates to blood glucose values can vary immensely from person to person. But, research suggests that eating processed foods can increase blood glucose.

Overeating or grazing

Itâs a common belief that snacking throughout the day will keep blood glucose levels steady. But, a 2013 study found that eating two large meals per day helped reduce blood glucose more effectively than six small meals per day. Itâs also important to keep our meals to the right proportions, as overeating can raise blood glucose levels as well.

Dehydration

Some research has found a connection between low water intake and a greater risk of hyperglycemia. This is most likely because less water in the body means the concentration of glucose in the blood is higher.

Vitamin and mineral deficiencies

Research into this cause is ongoing. Yet, studies suggest diets lacking micronutrients like chromium, magnesium, or vitamin D may contribute to high blood glucose.

Is Having High Blood Glucose Dangerous

In short, it can be. Zanini says that untreated high blood glucose can lead to a wide range of health issuesâsome of the most common being chronic inflammation, heart disease, vision impairment, kidney disease, nerve damage, tooth decay, damaged blood vessels, and periodontal disease.

Having high blood glucose also puts us at risk of mitochondrial dysfunction and oxidative stress. The former is a condition in which mitochondria fail to produce energy for cells. The latter occurs when free radicals outnumber antioxidants in the body and increase the risk of disease and other damage.

Phipps notes to avoid these risks, catching high blood glucose early on, then taking action to treat it is extremely important.

How To Prevent Hyperglycaemia

There are simple ways to reduce your risk of severe or prolonged hyperglycaemia:

  • Be careful what you eat be particularly aware of how snacking and eating sugary foods or carbohydrates can affect your blood sugar level.
  • Stick to your treatment plan remember to take your insulin or other diabetes medications as recommended by your care team.
  • Be as active as possible getting regular exercise can help stop your blood sugar level rising, but you should check with your doctor first if you’re taking diabetes medication, as some medicines can lead to hypoglycaemia if you exercise too much
  • Take extra care when you’re ill your care team can provide you with some “sick day rules” that outline what you can do to keep your blood sugar level under control during an illness.
  • Monitor your blood sugar level your care team may suggest using a device to check your level at home, so you can spot an increase early and take steps to stop it.
