Experiencing high blood glucose levels can be concerning, especially if you’re not diabetic. Blood sugar fluctuations are commonly associated with diabetes, but they can occur in people without the condition as well. For certain people, causes of high blood glucose other than diabetes can be stress, infections, diet, and prediabetes, can elevate blood glucose levels. It’s essential to understand what causes high blood sugar without diabetes to maintain healthy glucose levels, prevent prediabetes from progressing, and ensure your body functions optimally.
This blog will explore the potential causes of high blood glucose levels in non-diabetic individuals, the symptoms to look out for, and lifestyle changes that can help regulate glucose.
Pre-diabetes vs. Diabetes: What’s the Difference?
The terms prediabetes and diabetes often come up in discussions about blood sugar, but they represent different stages of glucose regulation issues. Prediabetes is a condition where blood glucose levels are higher than normal but not high enough to be classified as diabetes. It signals an increased risk for developing type 2 diabetes but is often reversible with lifestyle changes.
Prediabetes:
A fasting blood glucose level between 100-125 mg/dL or an HbA1c level of 5.7% to 6.4%.
Diabetes:
A fasting blood glucose level of 126 mg/dL or higher or an HbA1c level of 6.5% or above. If prediabetes progresses untreated, the likelihood of developing type 2 diabetes increases significantly. This makes it crucial for people with prediabetes to manage blood sugar levels through lifestyle adjustments.

Common Causes of High Blood Glucose Other Than Diabetes
Even without diabetes, various factors can lead to elevated blood glucose. Here are some of the most common causes of high glucose other than diabetes:
1. Stress
The top reason for high glucose without diabetes could be stress. When you experience stress, your body releases hormones like cortisol and adrenaline, which prompt the liver to release glucose for a quick energy boost. This is also termed ‘stress hyperglycemia’. According to the National Institutes of Health, stress hyperglycemia happens because the liver releases more glucose into the bloodstream rather than because the body’s tissues can’t absorb glucose properly. For short-term stress, this isn’t problematic. However, chronic stress can lead to sustained high glucose levels, increasing the risk of developing insulin resistance.
2. Poor Diet and Eating Habits
Causes of high glucose other than diabetes also include a poor diet. High-carbohydrate or high-sugar meals can cause sudden increases in blood glucose, even in non-diabetics. What causes blood sugar to rise in non-diabetics include consuming processed foods, sugary snacks, and beverages with high glycemic indexes, which can strain your body’s ability to manage glucose effectively, especially if these choices are regular. Frequent indulgence in these types of food can eventually impair insulin sensitivity, leading to prediabetes.
3. Sedentary Lifestyle
Physical activity helps regulate blood glucose levels by improving insulin sensitivity and allowing muscles to absorb more glucose. A sedentary lifestyle, in contrast, can lead to weight gain and make it harder for the body to control blood sugar levels, creating a higher risk of elevated glucose levels over time. When considering what causes high glucose in non-diabetics, a lack of regular physical activity is a significant factor, as it directly impacts the body’s ability to manage and stabilize blood sugar.
4. Hormonal Imbalances
Another reason for high glucose without diabetes could be hormonal changes. Hormonal changes during puberty, menopause, or conditions like polycystic ovary syndrome (PCOS) can affect glucose regulation. In these cases, insulin resistance may increase, making it more challenging for the body to manage blood glucose levels effectively.
5. Infections or Illness
Causes of high glucose other than diabetes also include infections. During an infection or illness, blood glucose levels may rise as part of the body’s natural immune response. The body releases hormones to fight the infection, which can simultaneously increase blood sugar levels. This elevation is usually temporary and returns to normal once the infection is resolved, but prolonged illness can lead to sustained higher glucose levels.
6. Lack of Sleep
Sleep is essential for regulating glucose metabolism. Chronic sleep deprivation can increase insulin resistance and elevate blood glucose levels. Understanding what causes high blood sugar without diabetes, such as insufficient sleep, is crucial, as studies by the NIHhave shown that people who consistently lack proper rest are more likely to experience impaired glucose tolerance.
7. Certain Medications
WebMD states that some medications, such as corticosteroids and beta-blockers, can elevate blood sugar levels as a side effect. When exploring what can cause high blood sugar other than diabetes, corticosteroids are a notable example, as they are commonly prescribed for inflammation but can cause blood glucose to spike, particularly with long-term use.
Symptoms of High Blood Glucose Levels Without Diabetes
Recognizing what causes high glucose in non diabetics can help you take timely action. Even if you don’t have diabetes, high blood glucose levels can still cause certain symptoms:
Frequent Urination:
Excess glucose causes your kidneys to work harder, leading to more frequent urination.
Increased Thirst:
As your body loses more water through urination, you may feel an urge to drink more to stay hydrated.
Fatigue:
Elevated glucose levels can disrupt energy production, making you feel tired or sluggish.
Blurred Vision:
High glucose levels can cause the lens in your eye to swell, leading to temporary blurred vision.
Headaches:
Frequent high blood sugar can trigger headaches, especially if you’re dehydrated from increased urination.
These symptoms can often be mild but should not be ignored, particularly if they recur or worsen. If you experience any of these symptoms, it’s wise to consult a healthcare professional and get tested for blood glucose levels.
When To Get Tested
If you notice persistent symptoms of elevated blood glucose, it’s essential to get tested, even if you don’t have a diabetes diagnosis. Routine tests, such as fasting blood sugar and HbA1c tests, can provide insights into your glucose levels.
People at higher risk, such as those with a family history of diabetes or with prediabetes symptoms, should consider regular screenings. Early detection allows you to make lifestyle changes that can prevent the progression of type 2 diabetes.
Lifestyle Changes to Manage Blood Glucose Levels
Making small adjustments to your daily habits can help manage and stabilize your blood glucose levels. Here are some effective lifestyle changes:
-
Eat a Balanced Diet
Knowing what causes high blood sugar in non-diabetics is important, but one should get down to fixing it immediately. Focus on a diet rich in whole grains, lean proteins, vegetables, and healthy fats. Avoid high-glycemic-index foods that cause rapid blood sugar spikes. Include fiber-rich foods, such as legumes and leafy greens, which help slow down glucose absorption and keep levels stable.
-
Exercise Regularly
Regular exercise can improve insulin sensitivity and help your body use glucose more efficiently. Aim for at least 150 minutes of moderate-intensity exercise per week, such as brisk walking, cycling, or swimming.
-
Manage Stress
Practicing stress-reducing activities, such as mindfulness meditation, yoga, or deep breathing exercises, can help regulate cortisol levels and prevent stress-related glucose spikes. Reducing chronic stress is key to maintaining stable blood sugar levels.
-
Get Enough Sleep
Prioritize 7-9 hours of sleep each night. Sleep is essential for glucose metabolism, and adequate rest can improve your body’s insulin response, helping keep blood sugar levels in check.
-
Limit Processed and Sugary Foods
Processed foods and sugary beverages often have high glycemic indexes, leading to rapid increases in blood sugar. Avoiding or limiting these can help you maintain steady glucose levels and prevent insulin resistance.
The Impact of Diet and Stress on Blood Glucose Levels
Diet and stress are two of the most significant contributors to the causes of high blood sugar other than diabetes. Poor dietary choices, such as high intake of refined carbs and sugary drinks, can overwhelm the body’s insulin response, leading to insulin resistance and elevated blood sugar.
Stress, whether physical, emotional, or mental, also impacts blood sugar due to the release of stress hormones like cortisol, which prompts the liver to release glucose. Chronic stress can increase your risk of insulin resistance and lead to long-term blood sugar control issues.
Together, diet and stress management are crucial in maintaining healthy glucose levels. Eating balanced meals and practicing stress-reduction techniques can improve overall blood sugar control.
