Hypoglycemia (Low Blood Sugar) Symptoms, Causes, & Treatment

Hypoglycemia, or low blood sugar, happens when the level of glucose in your blood drops too low. It can make you feel shaky, tired, dizzy, or confused. This condition is common in people with diabetes, but it can also affect others. Understanding the symptoms, causes, and treatment options can help you manage hypoglycemia effectively and stay healthy.

What is Hypoglycemia?

Hypoglycemia is a condition where your blood sugar (glucose) level falls below normal. Glucose is the main source of energy for your body, especially the brain. When levels drop too low, it can cause symptoms like shakiness, sweating, confusion, and even fainting.

It often happens in people with diabetes who take insulin or other medications, but it can also occur in others due to diet, illness, or other health conditions.

Causes of Hypoglycemia

As said above, hypoglycemia can be seen in both people with diabetes and non-diabetes. Hence, here are the causes of hypoglycemia with and without diabetes.

Hypoglycemia Without Diabetes

In this case, the following are the main reasons for hypoglycemia:

Medicines: Some medications, like those for malaria, can lower blood sugar. Always check with your doctor before using any new medication.
Alcohol Consumption: Drinking alcohol on an empty stomach can affect how your liver controls blood sugar, leading to hypoglycemia.
Certain Illnesses: Conditions like liver or kidney disease can interfere with normal blood sugar levels.
Eating Disorders: People with very low calorie intake or conditions like anorexia may experience low blood sugar.
Insulinoma: A rare tumor in the pancreas that causes too much insulin production, which lowers blood sugar levels.
Hormone Disorders: Problems with the adrenal or pituitary glands can reduce glucose production in the body, causing hypoglycemia.

Hypoglycemia with Diabetes

Diabetes Medications: People with diabetes often take insulin or other medicines to lower high blood sugar. If too much is taken or not balanced with food, it can lead to low blood sugar.
Skipping Meals: Taking diabetes medicine and then skipping a meal can cause sugar levels to drop too low.
Too Much Exercise: Exercising more than usual without adjusting food intake or medicine can also lead to hypoglycemia.

Diagnosis of Hypoglycemia

To diagnose hypoglycemia, doctors look at symptoms, blood sugar levels, and how your body responds to sugar intake.

Here are the main steps involved:

Blood sugar test shows level below 70 mg/dL
Presence of symptoms like shakiness, sweating, or confusion
Symptoms improve after eating or drinking sugar
Fasting tests may be done under medical supervision
Additional blood tests or imaging if a tumor or hormone issue is suspected

Treatment options for Hypoglycemia

Here are some treatment options for hypoglycemia (low blood sugar), depending on its severity and cause:

Eat or drink fast-acting carbs: Consume 15–20 grams of sugar like fruit juice, glucose tablets, or regular soda.
Follow the 15-minute rule: Check your blood sugar 15 minutes after treating. If it’s still low, repeat.
Eat a balanced snack: After stabilizing, eat something with protein and carbs, like a sandwich or yogurt, to prevent another drop.
Adjust diabetes medication: If you're diabetic, your doctor may adjust insulin or other medications.
Avoid alcohol on an empty stomach: Alcohol can trigger low blood sugar, especially without food.
Treat underlying conditions: Manage hormone disorders, tumors (like insulinoma), or liver/kidney disease that may cause hypoglycemia.
Wear a medical ID: For recurring episodes, wearing a medical bracelet can help in emergencies.
Emergency glucagon: In severe cases, a glucagon injection may be needed if the person is unconscious or unable to eat.

How to Prevent Hypoglycemia?

To prevent hypoglycemia, eat small, balanced meals regularly throughout the day. Include complex carbs, protein, and healthy fats to keep your blood sugar steady. Check your sugar levels often and take your medications as directed by your doctor. Avoid alcohol and carry sugary snacks like juice or fruit for emergencies. Staying active and wearing a medical alert ID can also help keep you safe.
