At Florida Endocrinology and Diabetes Center, our mission is to provide comprehensive care and education to help individuals manage and understand their health. For those with diabetes or those at risk, it’s essential to understand hypoglycemia—commonly known as low blood sugar. This condition can be dangerous if left untreated and can lead to severe complications. In this blog, we will explore the signs, symptoms, causes, and treatment options for hypoglycemia, along with how you can prevent it from occurring.
What is Hypoglycemia?
Hypoglycemia refers to abnormally low blood glucose (sugar) levels, typically below 70 mg/dL. Blood glucose is the body’s primary source of energy, and it is regulated by insulin, a hormone produced by the pancreas. While high blood sugar (hyperglycemia) is more commonly associated with diabetes, low blood sugar is also a significant concern, especially for individuals who take insulin or certain oral medications for diabetes management.
The body depends on glucose for energy, and when glucose levels drop too low, it can lead to a range of symptoms that can affect both physical and cognitive function. If left untreated, hypoglycemia can result in serious consequences, such as confusion, seizures, unconsciousness, or even death.
Causes of Hypoglycemia
There are various causes of hypoglycemia, and they often depend on individual circumstances, such as diabetes management or other underlying conditions. Some of the most common causes include:
1. Diabetes Medications
For individuals with diabetes, hypoglycemia is often a result of the use of insulin or oral medications like sulfonylureas. These medications lower blood sugar levels, and if too much medication is taken, or if food intake is insufficient, blood sugar levels can drop too low.
2. Skipping or Delaying Meals
When you skip meals or delay eating, your body may not have enough glucose available to maintain normal blood sugar levels, particularly if you are taking medication that lowers blood sugar.
3. Excessive Physical Activity
Intense or prolonged exercise can lower blood sugar levels, especially if you don’t adjust your food intake or medication accordingly. Exercise increases the body’s demand for glucose, and without proper management, blood sugar can drop to unsafe levels.
4. Alcohol Consumption
Drinking alcohol, especially on an empty stomach, can lower blood sugar levels. Alcohol impairs the liver’s ability to release glucose into the bloodstream, which can lead to hypoglycemia.
5. Hormonal Imbalances or Medical Conditions
Certain hormonal imbalances or medical conditions, such as Addison’s disease, liver disease, or kidney failure, can also contribute to low blood sugar levels. Additionally, tumors in the pancreas that produce excessive insulin (insulinomas) can cause hypoglycemia.
6. Taking Too Much Insulin or Diabetes Medication
Sometimes, individuals with diabetes may take more insulin or medication than necessary, either intentionally or unintentionally, which can lead to hypoglycemia.
Signs and Symptoms of Hypoglycemia
Recognizing the symptoms of hypoglycemia early is essential to prevent the condition from becoming severe. Symptoms can vary depending on the severity of the drop in blood sugar. These can range from mild symptoms that are easily managed to more severe symptoms that require immediate intervention.
1. Shakiness and Tremors
One of the earliest signs of hypoglycemia is shaking or trembling. This is your body’s response to low blood sugar, as it tries to release stored glucose from the liver to raise blood sugar levels. If you notice your hands shaking, it may be a sign that your blood sugar is dropping.
2. Sweating
Excessive sweating, especially when not caused by physical activity or heat, is another common symptom of low blood sugar. This occurs as the body tries to compensate for the lack of glucose by releasing stress hormones, such as adrenaline, which causes sweating.
3. Hunger
If you experience a sudden, intense feeling of hunger that comes on quickly, this could indicate hypoglycemia. The body signals hunger to try to increase glucose intake and raise blood sugar levels.
4. Dizziness or Lightheadedness
Low blood sugar can make you feel dizzy or lightheaded, as the brain relies on glucose to function. When blood sugar is too low, the brain doesn’t have the fuel it needs to operate properly, leading to these symptoms.
5. Headache
A headache is another common symptom of hypoglycemia, and it often occurs as a result of the brain not receiving enough glucose. The headache may be dull and throbbing or sharp, depending on the severity of the hypoglycemia.
6. Confusion or Difficulty Concentrating
As blood sugar drops, your cognitive function may be impaired. This can result in confusion, difficulty focusing, or an inability to think clearly. This symptom can be especially concerning, as it can lead to dangerous situations if left unaddressed.
7. Irritability or Mood Swings
Hypoglycemia can cause irritability, anxiety, and mood swings. The brain’s inability to receive adequate glucose causes emotional distress and can lead to sudden feelings of frustration or agitation.
8. Weakness or Fatigue
Low blood sugar can also cause weakness and fatigue. As the body lacks the glucose needed for energy, it can lead to feelings of exhaustion, making it difficult to perform routine tasks.
9. Seizures or Loss of Consciousness
In severe cases of hypoglycemia, the symptoms can escalate to seizures or even loss of consciousness. These symptoms are medical emergencies that require immediate treatment. If left untreated, severe hypoglycemia can lead to brain damage or even death.
How to Treat Hypoglycemia
The good news is that hypoglycemia is treatable, and with quick action, most individuals can manage low blood sugar effectively. It’s important to act quickly when symptoms of hypoglycemia are noticed to avoid progression to more severe symptoms.
1. Eat or Drink Something with Sugar
When you first notice symptoms of low blood sugar, the best course of action is to consume fast-acting carbohydrates. The American Diabetes Association recommends the following:
- 15–20 grams of glucose (e.g., glucose tablets or gel)
- 1/2 cup of fruit juice
- 1/2 cup of regular (non-diet) soda
- 1 tablespoon of sugar or honey
These fast-acting sugars are absorbed quickly into the bloodstream, helping to raise blood sugar levels within 15-20 minutes.
2. Recheck Blood Sugar Levels
After consuming sugar, recheck your blood sugar levels to ensure they have risen to a safe range. It’s important to monitor your blood sugar regularly to prevent another episode of hypoglycemia.
3. Eat a Balanced Meal
Once your blood sugar is back in a safe range, it’s important to eat a balanced meal or snack containing protein, fat, and carbohydrates. This helps stabilize blood sugar levels and prevent further drops.
4. Avoid Exercising Until Blood Sugar Levels Stabilize
Exercise can further lower blood sugar levels, so it’s important to avoid strenuous physical activity until your blood sugar has stabilized.
5. Use Glucagon in Severe Cases
In severe cases of hypoglycemia, when a person is unable to consume sugar or becomes unconscious, glucagon (a hormone that raises blood sugar) may need to be administered. This is typically given as an injection or nasal spray by a caregiver or family member. Emergency medical help should be sought immediately.
Preventing Hypoglycemia
Preventing hypoglycemia is the best way to avoid the dangerous symptoms associated with low blood sugar. Here are some tips for preventing hypoglycemia:
- Monitor Blood Sugar Regularly: Keeping track of your blood sugar levels is the best way to prevent low blood sugar. Use a glucose meter or continuous glucose monitor (CGM) to regularly check your levels.
- Eat Regular, Balanced Meals: Eating balanced meals and snacks regularly can help maintain stable blood sugar levels throughout the day.
- Adjust Medications as Needed: Work with your healthcare provider to ensure that your medications are properly adjusted to your needs. If you experience frequent hypoglycemia, your medication doses may need to be altered.
- Exercise Smartly: If you plan to exercise, make sure your blood sugar levels are in a safe range before starting. Carry fast-acting carbohydrates with you during exercise in case your blood sugar drops.
- Avoid Alcohol on an Empty Stomach: If you drink alcohol, do so with food to prevent low blood sugar, especially if you take insulin or other diabetes medications.
When to Seek Medical Attention
If hypoglycemia is not resolved after consuming sugar or if you experience severe symptoms such as seizures or loss of consciousness, seek emergency medical care immediately. Additionally, if you experience frequent or unexplained episodes of low blood sugar, it’s essential to discuss this with your healthcare provider to make necessary adjustments to your treatment plan.
