Have you ever experienced a feeling of extreme thirst, blurry vision, or a constant need to urinate? These could be signs of high blood sugar or hyperglycemia. The condition occurs when too much glucose or sugar is in the bloodstream, which can lead to serious health complications if left untreated.

This article explores everything you need to know about hyperglycemia, including its meaning, symptoms, causes, and treatment options. Whether you or someone you know is living with or looking to learn more about blood sugar levels, this guide will provide valuable information to help you better understand this condition.

What is hyperglycemia?

Hyperglycemia means having too much sugar or glucose in your bloodstream. Normally, our bodies break down the carbohydrates we consume into glucose, which is then used by our cells for energy. However, in cases of hyperglycemia, the glucose cannot enter the cells properly and instead accumulates in the bloodstream. [1]

Hyperglycemia is most commonly associated with diabetes. It is a condition where the body has difficulty producing or using insulin, a hormone that helps regulate blood sugar levels. [1] Hyperglycemia can damage blood vessels and organs over time. Monitoring blood sugar levels regularly and taking action if they become too high is crucial. [2]

What are the symptoms of hyperglycemia?

If you’re experiencing hyperglycemia, your body will give you a few tell-tale signs. Here are some common symptoms of high blood sugar levels:

Increased thirst

Your body will compensate for the high blood sugar levels by trying to flush out the excess glucose through urine. It can make you feel dehydrated and thirsty. [3]

Frequent urination

As your body tries to eliminate excess glucose through urine, you may need to urinate more often. [3]


You may feel lethargic or sluggish when your body can’t use glucose properly for energy. [1]

Weight loss

In some cases, high blood sugar levels can cause weight loss despite increased appetite. [1]

Altered mental status

In extreme cases, severe hyperglycemia can cause confusion, difficulty concentrating, and even loss of consciousness. [1]

What is the Hyperglycemia diagnosis?

In Hyperglycemia, glucose levels present in the blood sample are:

  1. greater than 125 mg/dL while fasting and
  2. greater than 180 mg/dL 2 hours after a meal

Impaired glucose tolerance or pre-diabetes is indicated by a fasting plasma glucose of 100 mg/dL to 125 mg/dL. [1]

When to seek medical help?

Most people who have hyperglycemia complain of thirst, sweet cravings, generalized fatigue, abdominal discomfort, and muscle cramps.

Here are a few symptoms or issues that require patients to seek medical attention:

  1. Frequent Urination
  2. Sudden Weight Loss
  3. Lethargy
  4. Increased thirst

Even when you’re on medication for hyperglycemia, stop taking the medication and seek medical attention if they develop nausea, vomiting, abdominal pain, and dyspnea, as well as having their urine and serum for ketones promptly tested. [9]

What are the causes of hyperglycemia?

Let’s take a look at some common factors that contribute to hyperglycemia:


Diabetes is the most common cause of hyperglycemia. In type 1 diabetes, the body doesn’t produce enough insulin, while in type 2 diabetes, the body doesn’t use insulin properly. [1]


Certain medications, like glucocorticoids and phenytoin, can lead to hyperglycemia. [1]

Endocrine disorders

Cushing syndrome and pheochromocytoma can lead to hyperglycemia. [1]

Illness or infection

When you’re sick or have an infection, your body releases stress hormones that can cause blood sugar levels to rise. [4]


When you’re under stress, your body tends to release hormones that can cause blood sugar levels to increase. [4]
