Hypoglycemia

For many individuals, a blood sugar level below 70 milligrams per deciliter (mg/dL) or 3.9 millimoles per liter (mmol/L) is considered low. However, your personal target range may vary. Consult with your healthcare provider to determine the appropriate blood sugar level for you.

Recognizing and Treating Hypoglycemia

It’s essential to be aware of the early warning signs of hypoglycemia and respond promptly to prevent complications. Symptoms may include:

• Shakiness or trembling
• Sweating
• Rapid heartbeat
• Dizziness or lightheadedness
• Confusion or difficulty concentrating
• Hunger
• Irritability or mood changes

If you experience these symptoms, quickly consume a simple source of sugar, such as glucose tablets, hard candy, or fruit juice.

Informing Others

Educate your family and friends about the signs of hypoglycemia and how to assist you if you are unable to treat it yourself. This will ensure that you receive timely help in case of an emergency.

Symptoms

• Pale appearance
• Shakiness
• Dizziness or lightheadedness
• Sweating
• Hunger or nausea
• Irregular or rapid heartbeat
• Difficulty concentrating
• Fatigue
• Irritability or anxiety
• Headache
• Tingling or numbness of the lips, tongue, or cheek

Nighttime Symptoms

• Damp sheets or nightclothes due to perspiration
• Nightmares
• Tiredness, irritability, or confusion upon waking

Severe Signs and Symptoms

If untreated, hypoglycemia can worsen and lead to:

• Confusion, unusual behavior, or difficulty completing routine tasks
• Loss of coordination
• Difficulty speaking or slurred speech
• Blurred or tunnel vision
• Inability to eat or drink
• Muscle weakness
• Drowsiness

In severe cases, hypoglycemia may cause:

• Convulsions or seizures
• Unconsciousness
• Death (rare)

Individual Variations

Symptoms of hypoglycemia can vary from person to person and episode to episode. Some individuals may not experience any noticeable symptoms. It’s crucial to monitor your blood sugar levels regularly and track your symptoms to identify patterns associated with low blood sugar.

Causes

• Medication Overdose: Taking excessive insulin or other diabetes medications can lead to hypoglycemia.
• Dietary Factors: Consuming insufficient carbohydrates or meals with an imbalanced ratio of fat, protein, and fiber can contribute to low blood sugar.
• Alcohol Consumption: Drinking alcohol without eating enough food can cause hypoglycemia.
• Physical Activity: Exercise can burn blood glucose, especially for individuals taking insulin.
• Medications: Certain antibiotics and heart medications may increase the risk of hypoglycemia.
• Underlying Conditions: Rare pancreatic tumors that produce excessive insulin or deficiencies in certain hormones can contribute to hypoglycemia.
• Critical Illness: Sepsis or other severe illnesses can lead to low blood sugar levels.
• Weight Loss Surgery: Some types of weight loss surgery may cause hypoglycemia, typically occurring five or more years after the procedure.

Risk Factors

• Insulin Management: Taking excessive insulin, the wrong type of insulin, or administering it at the incorrect time can lead to hypoglycemia.
• Exercise: Exercising without consuming adequate food, engaging in more strenuous activity than usual, or delaying a meal can increase the risk of low blood sugar.
• Alcohol: Alcohol can interfere with the body’s ability to produce glucose.
• Medications: Certain diabetes medications, such as sulfonylureas, can elevate the risk of hypoglycemia.
• Other Health Conditions:
• Liver or Kidney Disease: These conditions can impair the body’s ability to regulate blood sugar.
• Critical Illnesses: Sepsis, heart failure, or severe infections can contribute to hypoglycemia.
• Hormone Deficiencies: Adrenocortical failure or other hormone deficiencies can affect blood sugar regulation.
• Malnutrition or Starvation: Inadequate nutrition can lead to low blood sugar levels.
• Tumors: Certain tumors that produce excessive insulin or insulin-like substances can cause hypoglycemia.

Complications

• Brain Damage: Untreated hypoglycemia can lead to permanent brain damage.
• Seizures: Hypoglycemia can trigger seizures.
• Coma: Severe hypoglycemia can result in coma.
• Cardiac Issues: Hypoglycemia may cause cardiac arrhythmias or cardiac arrest.
• Multi-Organ Failure: In severe cases, hypoglycemia can lead to multi-organ failure.
• Death: While rare, death can occur as a result of severe hypoglycemia.
• Other Potential Complications:
• Anxiety
• Confusion
• Cognitive impairment
• Weight loss or gain
• Blurred vision
• Difficulty concentrating
• Slurred speech
• Numbness

Prevention

• Regular Blood Sugar Monitoring: Check your blood sugar levels regularly, especially before and after meals, exercise, and bedtime. Use a blood sugar meter or a continuous glucose monitor (CGM).
• Consistent Eating: Avoid skipping or delaying meals and snacks, and maintain a consistent eating schedule.
• Adhere to Medication Instructions: Take your medication as prescribed by your doctor and at the recommended times.
• Adjust for Activity: If you increase your physical activity, you may need to adjust your medication or consume additional snacks.
• Carry Snacks: Keep a readily available snack with a fast-acting carbohydrate, such as fruit juice, glucose tablets, or hard candy, in your bag, car, or desk.
• Have an Emergency Glucagon Kit: Maintain an emergency glucagon kit at home and in other frequently visited locations.
• Wear a Medical Alert: Consider wearing a medical alert bracelet or necklace to inform others about your diabetes in case of an emergency.
• Educate Others: Teach your family, friends, and coworkers about hypoglycemia and how to assist you if you experience an episode.

When to see a doctor

Severe hypoglycemia can lead to serious complications, including seizures or unconsciousness. It’s crucial to have a plan in place for emergencies.

Inform Others

• Educate your family, friends, and coworkers about the signs and symptoms of hypoglycemia and how to respond in an emergency.

Prepare for Emergencies

• Glucagon: Ensure that trusted individuals know where your glucagon kit is located and how to administer it. Glucagon is a hormone that can raise blood sugar levels.
• Emergency Contact Information: Provide your family and friends with your emergency contact details and the nearest hospital.

Emergency Procedures

If you are with someone who is unresponsive or unable to swallow due to low blood sugar:

• Avoid Insulin: Do not administer insulin as it can further lower blood sugar levels.
• Do Not Give Fluids or Food: Avoid giving fluids or food to prevent choking.
• Administer Glucagon: If available, administer glucagon via injection or nasal spray.
• Call for Emergency Assistance: If glucagon is not available, you are unsure how to use it, or the person remains unresponsive, immediately call 911 or your local emergency services.
