Hyperglycemia

Overview

Hyperglycemia is a condition characterized by high levels of blood glucose in the body. It occurs when the body cannot effectively use or produce insulin, leading to an imbalance in glucose levels. Hyperglycemia can result from various factors, including insufficient insulin production, insulin resistance, improper diabetes management, stress, illness, or certain medications. If left untreated, hyperglycemia can lead to complications such as diabetic ketoacidosis or hyperosmolar hyperglycemic state. Maintaining a healthy blood sugar level through proper diet, exercise, medication, and monitoring is crucial for managing diabetes and preventing hyperglycemia.

Understanding the disease

Symptoms

The symptoms of hyperglycemia (high blood sugar) include:

  1. Increased thirst
  2. Frequent urination
  3. Blurred vision
  4. Feeling weak or unusually tired
  5. Headache
  6. Nausea and vomiting
  7. Shortness of breath
  8. Stomach pain
  9. Fruity breath odor
  10. A very dry mouth If left untreated, hyperglycemia can lead to more severe symptoms and health complications, including ketoacidosis. It's important to monitor blood sugar levels and seek medical attention if they remain consistently high or if other concerning symptoms are present.

Development

Hyperglycemia develops when the blood glucose levels in the body rise above normal levels, usually above 180-200 mg/dL (10-11.1 mmol/L). This can occur due to various factors, including:

  1. Insufficient insulin production or action: In people with diabetes, either the pancreas doesn't produce enough insulin (Type 1 diabetes) or the body becomes resistant to insulin (Type 2 diabetes), leading to hyperglycemia.
  2. Inadequate glucose uptake by cells: Cells may become resistant to insulin, which impairs glucose uptake and leads to hyperglycemia.
  3. Poor diabetes management: Skipping or not taking enough doses of insulin or other diabetes medications, irregular meals, and insufficient physical activity can contribute to hyperglycemia.
  4. Stress, illness, or injury: These factors can cause hormonal imbalances that raise blood sugar levels.
  5. Infections or inflammation: Certain infections or inflammatory conditions can raise blood glucose levels. Hyperglycemia can have serious consequences if left untreated, leading to a range of health complications, including diabetic ketoacidosis, diabetic hyperosmolar syndrome, and long-term damage to organs such as the eyes, kidneys, nerves, and heart.

Assessment and Diagnosis

Triage

You should see a doctor if hyperglycemia is suspected when:

  1. Your blood glucose levels stay above 240 milligrams per deciliter (mg/dL) (13.3 millimoles per liter (mmol/L)) and you have symptoms of ketones in your urine.
  2. You have ongoing diarrhea or vomiting, and you can't keep any food or fluids down. If you experience any of these symptoms, seek immediate help from your care provider or call 911. It's important to monitor your blood sugar levels regularly and keep track of how you're feeling when your blood sugar is low.

Management and Treatment

Complications

The potential complications of hyperglycemia include:

  • Cardiovascular disease
  • Nerve damage (neuropathy)
  • Kidney damage (diabetic nephropathy) or kidney failure
  • Uncontrolled high blood pressure (hypertension)
  • High blood cholesterol
  • Obesity
  • Family history of diabetes and kidney disease
  • Complications of diabetic nephropathy, such as fluid retention, high potassium levels, heart and blood vessel disease, diabetic retinopathy, anemia, foot sores, erectile dysfunction, diarrhea, and bone and mineral disorders.
  • Later signs and symptoms of hyperglycemia may include frequent urination, increased thirst, blurred vision, feeling weak or unusually tired, fruity-smelling breath, dry mouth, abdominal pain, nausea and vomiting, shortness of breath, confusion, and loss of consciousness. It's important to treat hyperglycemia to prevent these complications and maintain proper blood sugar control. If you experience ongoing diarrhea or vomiting, or if your blood glucose levels stay above 240 mg/dL with symptoms of ketones in your urine, seek immediate medical help from your care provider or call 911.

Treatment

Treatment for hyperglycemia (high blood sugar) typically involves addressing the underlying cause and making lifestyle changes. For hyperosmolar hyperglycemic state, which is characterized by high blood sugar levels (greater than 600 mg/dL) without ketoacidosis, the following treatments are recommended:

  1. Hydration: Encourage the consumption of water and electrolytes to help replenish fluids and prevent dehydration.
  2. Insulin therapy: Administer insulin to lower high blood sugar levels. The type and dosage of insulin will depend on the individual's specific condition and medical history.
  3. Glucose administration: Provide the person with glucose in the form of a gel, tablet, or liquid to quickly raise their blood sugar levels.
  4. Electrolyte replacement: If electrolyte levels are low, administer appropriate electrolyte replacement solutions.
  5. Monitor blood sugar levels: Continuously monitor blood sugar levels to ensure they return to a healthy range. It's essential to seek prompt medical attention for hyperglycemia, especially in cases of hyperosmolar hyperglycemic state, as it can lead to life-threatening complications if left untreated.

Preparing for medical consultation

To prepare for an appointment related to hyperglycemia, you should:

  1. Be aware of any pre-appointment restrictions: Ask your healthcare provider if you need to fast or restrict your diet before the appointment.
  2. Record your blood glucose meter values: Keep a record of your blood sugar levels, including times and medications taken, to share with your healthcare provider. This can help identify patterns and trends related to hyperglycemia.
  3. Write down key personal information: Prepare a list of any major stresses, recent life changes, or symptoms you're experiencing, including those that may seem unrelated.
  4. Make a list of medications, vitamins, and supplements: Create a record of all the medications, vitamins, and supplements you are currently taking, including dosages, to share with your healthcare provider.
  5. Bring a record of your glucose values, if self-monitoring: If you check your blood sugar levels at home, bring a record of your recent readings, including dates and times, to share with your healthcare provider.
  6. Create a list of questions to ask your healthcare provider: Prepare a list of questions you may have about your hyperglycemia, treatment options, or any concerns you want to discuss. Remember to inform your healthcare provider about any changes in your condition, symptoms, or medication since your last appointment. Following these steps can help ensure a productive appointment and effective management of your hyperglycemia.
