Low Blood Sugar vs. High Blood Sugar: What’s the Difference?

Low Blood Sugar vs. High Blood Sugar: What’s the Difference?

When blood glucose, also known as blood sugar, is too high, it can lead to diabetes. Your main energy source is blood glucose, which is obtained from the food you eat. The pancreas produces the hormone insulin, which facilitates the uptake of glucose from food into your cells for use as fuel. Your body occasionally produces insufficient or no insulin, or it uses insulin poorly. Consequently, glucose doesn’t get to your cells and remains in your blood.

Low Blood Sugar

Hypoglycemia, also known as low blood glucose, is a condition in which the blood’s glucose levels are too low to support normal bodily functions.



Diabetes-related side effects are primarily among the causes of low blood glucose level. However, it may also result from:

Low blood sugar can have both short-term (such as confusion and dizziness) and long-term (such as coma or even death) complications.

How can you treat Low Blood Sugar Level?

The first thing you have to do is, use a glucose meter to check your blood sugar levels. Start with quick-acting carbohydrates, such as juice or candy, if your blood sugar levels aren’t too low (keep an eye on the nutrition facts on your food labels to monitor your intake). Other viable options include glucose tablets or glucose gel. Keep in mind that 15 grams of carbohydrates are a small amount of food and that liquid glucose is absorbed more quickly than solid glucose. Check your sugar level in every 10-15 minutes.

Blood Sugar Level

High Blood Sugar

Blood sugar levels need to be brought down to a safe level to prevent hyperglycemia from occurring. Mild to severe hyperglycemia is possible.



Among the short-term effects of hyperglycemia are nausea, vomiting, shortness of breath, and dry mouth. Hyperglycemia can have long-term effects, such as kidney damage, blindness, nerve damage, and cardiovascular diseases.

How can you treat High Blood Sugar Level?

Finding out why blood glucose levels are high is the very first step. If carbohydrates are consumed without an insulin dose, an additional insulin dose may be required. Remember to also take into account any additional activities. If you exercise, it might help lower your blood glocose.

Even with the best preparation, blood-sugar levels can rise unexpectedly, necessitating the administration of an additional dose of insulin, according to doctors. Keep in mind that the automated insulin delivery system will give you extra insulin when choosing the amount of insulin, you might manually administer.

Check for ketones in the blood or urine if you experience frequent high blood sugars (generally above 300 mg/dL that do not decrease despite an additional dose of insulin) or severe high level symptoms like nausea, abdominal pain, or vomiting.

The body will attempt to use an alternative fuel source for energy, such as fat when insulin is absent or not functioning properly and the body cannot absorb enough glucose. Ketones, which are produced when fat is broken down, can make the blood acidic and cause very serious illnesses.

Want to Know which one is more Dangerous?

Some people are afraid of having high diabetes, while others are afraid of having low diabetes. No matter if your blood-sugar level is high or low, it is risky if the range is abnormal. The severe symptoms of low blood sugar are caused by our body’s attempt to protect itself by acting as an emergency alarm. An absence of ketones coupled with low blood sugar levels can be fatal. High levels of ketones can also cause a fatal condition known as ketoacidosis. High blood sugar has long-term negative effects on the arteries and veins.

Final Words

Controlling blood sugar levels can be challenging at times. Having a glucometer on hand will help with better diabetes management and blood sugar monitoring. A glucometer with a smart app makes it easy to check sugar levels from any location. You can consult a diabetes clinic in Denver for the best guidance. The doctors of the clinic can provide you with advice based on your age, lifestyle, and medications.
