High blood sugar occurs when there's too much glucose (sugar) in the blood. This can happen if your body doesn't produce enough insulin (in the case of type 1 diabetes), or if your body doesn't use insulin properly (in the case of type 2 diabetes or insulin resistance). Other factors like stress, illness, certain medications, and diet can also contribute to elevated blood sugar levels. Chronic hyperglycemia can lead to serious health problems, including heart disease, kidney disease, nerve damage, and vision problems.

The Complete High Blood Sugar Symptom Checklist
Recognizing the symptoms of high blood sugar is crucial for early detection and treatment. Here's a detailed checklist of common and less common signs to look out for:
- Frequent Urination (Polyuria): The kidneys try to flush out excess sugar, leading to increased urination, especially at night.
- Increased Thirst (Polydipsia): Due to fluid loss from frequent urination, you may feel excessively thirsty.
- Unexplained Weight Loss: Despite eating normally (or even more), you might lose weight because your body isn't properly using glucose for energy.
- Increased Hunger (Polyphagia): Despite high blood sugar levels, your cells may not be getting enough glucose, leading to persistent hunger.
- Blurred Vision: High blood sugar can affect the lens of the eye, causing temporary blurry vision.
- Fatigue and Weakness: When your cells don't receive enough glucose, you may feel tired and weak.
- Slow-Healing Cuts and Sores: High blood sugar can impair wound healing.
- Frequent Infections: Hyperglycemia can weaken your immune system, making you more susceptible to infections, especially skin infections, urinary tract infections, and yeast infections.
- Dry, Itchy Skin: Dehydration caused by frequent urination can lead to dry, itchy skin.
- Numbness or Tingling in Hands or Feet (Neuropathy): Over time, high blood sugar can damage nerves, causing numbness, tingling, or pain in the extremities.
- Recurring Skin or Gum Infections: Infections take longer to heal when blood sugar is elevated.
- Erectile Dysfunction (in men): Nerve and blood vessel damage from high blood sugar can contribute to erectile dysfunction.
Recognizing Additional Symptoms & Warning Signs
Beyond the primary symptoms, keep an eye out for these additional indicators that may point to high blood sugar:
- Headaches: Changes in blood sugar can cause headaches.
- Difficulty Concentrating: High blood sugar can affect cognitive function.
- Nausea and Vomiting: In severe cases, high blood sugar can lead to nausea and vomiting. This is more common in type 1 diabetes and a condition called diabetic ketoacidosis (DKA).
- Fruity-Smelling Breath: A sign of DKA, a life-threatening complication where the body produces ketones due to lack of insulin.
- Stomach Pain: Can occur in severe cases of hyperglycemia, especially when DKA is present.
Severity of Symptoms and When to Seek Medical Attention
The severity of high blood sugar symptoms can vary depending on how elevated your blood sugar is and how long it's been elevated. Mild hyperglycemia might only cause slight fatigue or increased thirst. However, severe hyperglycemia can be life-threatening.
Seek immediate medical attention if you experience any of the following:
- Fruity-smelling breath
- Nausea and vomiting
- Shortness of breath
- Confusion or disorientation
- Loss of consciousness
- Severe abdominal pain
Even if your symptoms are mild, it's crucial to consult a doctor if you suspect you have high blood sugar. They can perform tests to determine your blood sugar levels and recommend an appropriate treatment plan.
Factors that Increase Your Risk of High Blood Sugar
Certain factors can increase your risk of developing high blood sugar:
- Family History of Diabetes: Having a close relative with diabetes increases your risk.
- Obesity or Overweight: Excess weight, particularly around the abdomen, increases insulin resistance.
- Inactivity: Lack of physical activity can lead to insulin resistance.
- Unhealthy Diet: A diet high in sugary drinks and processed foods can contribute to high blood sugar.
- Age: The risk of developing type 2 diabetes increases with age.
- Certain Medical Conditions: Conditions like polycystic ovary syndrome (PCOS) and gestational diabetes (diabetes during pregnancy) can increase your risk.
- Certain Medications: Some medications, such as steroids and certain antipsychotics, can raise blood sugar levels.
Testing and Diagnosis
The best way to determine if you have high blood sugar is to get tested by a healthcare professional. Common tests include:
- Fasting Plasma Glucose (FPG) Test: Measures your blood sugar after an overnight fast. A reading of 126 mg/dL or higher indicates diabetes.
- Oral Glucose Tolerance Test (OGTT): Measures your blood sugar two hours after drinking a sugary drink. A reading of 200 mg/dL or higher indicates diabetes.
- A1C Test: Measures your average blood sugar level over the past 2-3 months. An A1C of 6.5% or higher indicates diabetes.
- Random Plasma Glucose (RPG) Test: Measures your blood sugar at any time of day. A reading of 200 mg/dL or higher, along with symptoms of diabetes, indicates diabetes.

If you're experiencing symptoms of high blood sugar, here are the steps you should take:
- Consult a Doctor: Schedule an appointment with your doctor as soon as possible. Explain your symptoms and any risk factors you have.
- Monitor Your Blood Sugar (If Possible): If you have a blood glucose meter at home, check your blood sugar levels regularly and record the results.
- Follow Your Doctor's Recommendations: If your doctor diagnoses you with diabetes or prediabetes, follow their recommendations for treatment and lifestyle changes.
- Make Lifestyle Changes: Even if you don't have diabetes, adopting a healthy lifestyle can help prevent high blood sugar. This includes eating a balanced diet, exercising regularly, and maintaining a healthy weight.
Lifestyle Changes to Manage Blood Sugar
Adopting a healthy lifestyle is crucial for managing and preventing high blood sugar. Here are some key lifestyle changes you can make:
- Eat a Balanced Diet: Focus on whole, unprocessed foods, including fruits, vegetables, whole grains, and lean protein. Limit sugary drinks, processed foods, and refined carbohydrates.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Maintain a Healthy Weight: Losing even a small amount of weight can improve insulin sensitivity and lower blood sugar levels.
- Monitor Your Blood Sugar: If you have diabetes, check your blood sugar levels regularly and record the results. This will help you and your doctor track your progress and adjust your treatment plan as needed.
- Manage Stress: Stress can raise blood sugar levels. Find healthy ways to manage stress, such as exercise, meditation, or spending time with loved ones.
- Get Enough Sleep: Lack of sleep can affect insulin sensitivity and raise blood sugar levels. Aim for 7-8 hours of sleep per night.
Medical Treatments for High Blood Sugar
If lifestyle changes aren't enough to control your high blood sugar, your doctor may prescribe medications. The type of medication will depend on the type of diabetes you have and other health factors. Common medications include:
- Metformin: A common medication that helps improve insulin sensitivity and reduce glucose production in the liver.
- Sulfonylureas: Medications that stimulate the pancreas to produce more insulin.
- DPP-4 Inhibitors: Medications that help increase insulin production and reduce glucose production.
- GLP-1 Receptor Agonists: Medications that help increase insulin production, reduce glucose production, and slow down digestion.
- Insulin: Insulin therapy is used to replace the insulin that the body isn't producing.
Complications of Untreated High Blood Sugar
Untreated high blood sugar can lead to serious health complications, including:
Complication | Description |
---|---|
Cardiovascular Disease | Increased risk of heart attack, stroke, and peripheral artery disease. |
Neuropathy (Nerve Damage) | Nerve damage causing numbness, tingling, pain, and digestive problems. |
Nephropathy (Kidney Damage) | Kidney damage leading to kidney failure. |
