Hyperglycemia or high blood glucose means excessive amounts of blood sugar in the bloodstream, and this condition is associated with diabetes. It is caused due to the lack of insulin in the body or when the insulin is not functioning properly. Causes of high blood glucose can be excessive food intake, less physical activity, illness, and stress. It is crucial to diagnose and treat this medical condition before it becomes too severe and causes complications. One way to keep it in check is by regularly testing the blood glucose levels in diabetic patients.
The normal blood glucose levels in a body range from 80 to 130 mg/dL. Levels of sugar in the blood that are higher than this range indicate hyperglycemia, but the symptoms are not visible until after a few weeks. They slowly develop when the levels increase to 180 to 200 mg/dL.
Early signs and symptoms:
If hyperglycemia is left untreated, it may cause some serious complications like ketoacidosis, which is the accumulation of toxic ketones in the body. The symptoms associated with this condition include:
Long-term severe effects are eye, kidney, cardiovascular diseases, and sometimes even nerve damage. Read more about the high blood sugar level.
Hyperglycemia can be prevented by
Hypoglycemia, commonly known as low blood sugar, is a condition wherein the blood glucose drops below normal levels. It usually occurs in diabetic patients who take insulin medication. Apart from taking too much insulin, the other reasons blood glucose can dip to alarming levels are exercising too much, not eating enough, or skipping meals.
It is considered to be hypoglycemia when blood glucose levels fall below 70 mg/dL, and at this point, the primary functions in the body start deteriorating. As a short-term solution, the liver can produce glucose or convert stored glycogen into glucose. But these solutions can have adverse effects on the body.
Low blood glucose is commonly seen among Type I and Type 2 diabetic patients who take insulin medication.
Symptoms of this condition tend to appear suddenly and vary from person to person. The symptoms include:
People who have hypoglycemia are often not aware of their condition and when the blood glucose levels drop without notice, the absence of immediate treatment can lead to the patients fainting, experiencing a seizure, or going into a coma.
Low blood glucose is a medical emergency and, if you know someone who is experiencing symptoms, you can help them by having them eat or drink some form of carbohydrates. If this doesn’t work and the symptoms are severe, then administer a shot of glucagon immediately.
You can prevent hypoglycemia by
Hyperglycemia and hypoglycemia have very different causes and symptoms that make it easy for us to differentiate between the two. Hyperglycemia is caused due to excessive intake of food, less physical activity and stress, and shows signs of increased hunger, thirst, fatigue, urination and blurred vision.
Hypoglycemia is caused by less intake of food, excessive exercise and blood glucose-lowering medications. Symptoms are sweating, dizziness, nervousness, anxiety and needs immediate intervention.
One way to effectively remember the different mnemonics is:
- hyperglycemic patients are hot and dry, sugar high.
- hypoglycemic patients are cold and clammy, and they need candy.
Hyperglycemia has distinct symptoms that can be treated successfully if caught early on. The three main signs of high blood glucose are:
While both conditions deteriorate the health of an individual, hypoglycemia is considered to be more dangerous than hyperglycemia. This is because when a person has low blood glucose, the brain cells stop working completely and a person can even slip into a coma. Therefore, immediate intervention is required.
