Low Blood Sugar Vs High Blood Sugar

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.

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 Can I Treat High Blood Sugar

Talk to your doctor about how to keep your blood sugar levels within your target range. Your doctor may suggest the following:

• Be more active. Regular exercise can help keep your blood sugar levels on track. Important: dont exercise if ketones are present in your urine. This can make your blood sugar go even higher.
• Take medicine as instructed. If your blood sugar is often high, your doctor may change how much medicine you take or when you take it.
• Follow your diabetes meal plan. Ask your doctor or dietitian for help if youre having trouble sticking to it.
• Check your blood sugar as directed by your doctor. Check more often if youre sick or if youre concerned about high or low blood sugar.
• Talk to your doctor about adjusting how much insulin you take and what types of insulin to use.

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.

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.

When Should I Check My Blood Sugar

How often you check your blood sugar depends on the type of diabetes you have and if you take any diabetes medicines.

Typical times to check your blood sugar include:

• When you first wake up, before you eat or drink anything.
• Two hours after a meal.

If you have type 1 diabetes, have type 2 diabetes and take insulin, or often have low blood sugar, your doctor may want you to check your blood sugar more often, such as before and after youre physically active.

No Symptoms Be Alarmed

Surprisingly, the most dangerous episodes of hypoglycemia occur with little or no warning. When low blood glucose occurs on a regular basis, the body can become used to the warning signs and the person may stop noticing symptoms. This is a particularly dangerous condition known as hypoglycemic unawareness. People with this condition might not realize they have low blood glucose until it’s dangerously low seizures and coma are sometimes the first indication of a problem. The good news is that this condition can often be reversed allowing people to once again notice the signs of low blood glucose if hypoglycemia is avoided for a few weeks through careful monitoring of blood glucose.

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.

Time In Range Goals Stay Out Of The Highs And The Lows

Effective diabetes management is an attempt to stay in the target glucose range. This means that you should aim to spend as much time as possible with your glucose level between 70 to 180 mg/dL The amount of time you spend in this target zone is called your Time in Range and is measured by a continuous glucose monitor , though you can also measure TIR using your blood glucose meter. When glucose level exceeds 180 mg/dL, this is referred to as Time Above Range . If your glucose level goes below 70 mg/dL, this is Time Below Range .

For most people with diabetes, these are the recommended TIR goals :

• At least 70% of the day in range this is almost 17 hours a day

• Less than 4% of the day below range this is 1 hour a day

• Less than 1% of the Time Below Range less than 54 mg/dL or 3.0 mmol/L this is 15 minutes a day

These are general recommendations, however, you should strive for even more TIR and less Time Above and Below Range if possible.

Hypo Vs Hyper Your Greek Lesson For The Day

Glycemia is defined as the presence of glucose in the blood.

Hypo comes from the Greek word hupo, which translates as under or, more typically, less.

Hyper is also a holdover from the Greeks, from the Greek word huper, which translates as over or above.

So extending that logic, hypoglycemia is a low blood sugar level and hyperglycemia is a high blood sugar level.

Tingling Hands And Feet

Over the years, hyperglycemia can begin to impact nerve function and eventually cause nerve damage, called neuropathy, Dr. Hatipoglu says. The most common kind of neuropathy is peripheral, according to the NIDDK, which affects the extremities. You might start noticing feelings of tingling, numbness, or burning in your hands, feet, arms, and legs, per the Mayo Clinic.

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.

High Blood Sugar Causes

You may be thinking that hyperglycemia can happen just from eating a super-sugary food, but its not really as simple as that. Sure, eating a lot of sugar or carbs can elevate your blood sugar level, but thats typically when your pancreas kicks into gear and creates insulin to move that glucose into cells throughout the body.

But when someone has diabetes, this finely tuned system gets thrown out of whack. In type 2 diabeteswhich accounts for 90% to 95% of diabetes in adults, according to the CDCthe body either cant make enough insulin or cant utilize insulin well, according to the NIDDK. If someone has prediabetes, their blood glucose will be higher than normal but not quite in the type 2 diabetes range yet, per the NIDDK. And in type 1 diabetes, the body does not make insulin or makes very little.

In any case, the result is extra sugar hanging around the bloodstream, making you feel like total crap in the short term and putting your health at risk in the long term.

What Is Reactive Hypoglycemia

Reactive hypoglycemia is a rare condition that causes low blood sugar in the hours following a meal.

Researchers do not fully understand the cause of reactive hypoglycemia. However, they are aware that it stems from having too much insulin in the blood at the wrong time.

Below are conditions and circumstances that can cause both hypoglycemia and anemia at the same time, or individually.

Why Your Blood Sugar Level May Be Low

If blood sugar drops below 70 mg/dL, it is below normal levels. This can be caused by a variety of factors, such as:

• Not eating enough or missing a meal or snack
• Reducing the amount of carbohydrates you normally eat
• Alcohol consumption especially if youre drinking on an empty stomach
• Taking too much insulin or oral diabetes medication based on carbohydrates or activity levels
• Increased physical activity
• Side effects from medications

If you have diabetes, keep your blood glucose meter and sources of fast-acting glucose close by in case your blood sugar drops. This is especially important for people with hypoglycemia unawareness, which is a condition that causes symptoms of low blood sugar to go unnoticed.

Eating balanced meals and snacks at regular times throughout the day is a big part of maintaining normal blood glucose levels.
