Low blood sugar, medically known as hypoglycemia, occurs when the level of glucose (sugar) in the bloodstream drops below the normal range. Normal blood sugar levels typically range between 70 and 100 milligrams per deciliter (mg/dL) of blood when fasting, and they can rise slightly after eating. Hypoglycemia is usually defined as a blood sugar level below 70 mg/dL.
Hypoglycemia can be caused by various factors, including:
- Diabetes Medications: One of the most common causes is the use of medications to manage diabetes, such as insulin and certain oral medications. These drugs are designed to lower blood sugar levels, but if the dosage is too high or not matched with food intake and activity level, they can lead to hypoglycemia.
- Inadequate Food Intake: Skipping meals, not eating enough, or delaying meals can deprive the body of the glucose it needs to maintain normal blood sugar levels.
- Excessive Physical Activity: Engaging in intense or prolonged physical activity without adjusting food intake or insulin doses can lead to hypoglycemia. The body uses glucose for energy during exercise, and this can deplete blood sugar levels.
- Alcohol Consumption: Drinking alcohol, especially on an empty stomach or in excessive amounts, can lower blood sugar levels. The liver is involved in regulating blood sugar, and alcohol can impair its ability to release glucose into the bloodstream.
- Insulinoma: This is a rare tumor of the pancreas that produces excess insulin, leading to recurrent episodes of low blood sugar.
- Other Medical Conditions: Some medical conditions, such as certain hormonal disorders (e.g., adrenal or pituitary gland disorders) and liver disease, can disrupt the body’s ability to regulate blood sugar.
- Dumping Syndrome: After certain types of stomach surgery, such as gastric bypass surgery, food can be rapidly “dumped” into the small intestine, causing a surge in insulin and leading to hypoglycemia.
- Critical Illness: People who are critically ill, especially those in intensive care units, can experience low blood sugar due to a variety of factors, including stress and changes in metabolism.
- Medications and Toxins: Some medications, like certain antibiotics, and toxins can interfere with glucose metabolism and cause hypoglycemia.
- Congenital Hyperinsulinism: This is a rare genetic condition in infants where the pancreas produces too much insulin, leading to low blood sugar.

Symptoms of low blood sugar
Low blood sugar, also known as hypoglycemia, can manifest with a range of symptoms, which can vary in severity depending on how low the blood sugar levels drop. Common symptoms of low blood sugar include:
- Shakiness or Trembling: One of the most common early signs is a feeling of shakiness or trembling, often in the hands.
- Sweating: Excessive sweating, even when it’s not hot, is a common symptom of hypoglycemia.
- Rapid Heartbeat: Your heart may start to beat faster than usual.
- Hunger: A sudden and intense feeling of hunger can occur.
- Irritability or Mood Changes: Hypoglycemia can lead to irritability, mood swings, or a feeling of nervousness or anxiety.
- Dizziness or Lightheadedness: You might feel dizzy or lightheaded, potentially leading to difficulty walking or maintaining balance.
- Fatigue: Sudden tiredness or weakness can set in.
- Headache: Some individuals experience headaches during episodes of low blood sugar.
- Blurred Vision: Vision may become blurry, making it difficult to focus.
- Difficulty Concentrating: It can become challenging to concentrate or think clearly.
- Nausea: Nausea and, in some cases, vomiting may occur.
- Confusion: Severe hypoglycemia can lead to confusion, difficulty speaking, and impaired coordination.
- Seizures: In extreme cases, hypoglycemia can lead to seizures, although this is less common.
How to increase blood sugar level immediately
If you are experiencing low blood sugar (hypoglycemia) and need to increase your blood sugar levels quickly, it’s important to do so safely to avoid overcompensating and causing a spike in blood sugar. Here are some steps you can take to raise your blood sugar immediately:
- Consume Fast-Acting Carbohydrates: Fast-acting carbohydrates are the quickest way to increase blood sugar levels. These include:
- Glucose tablets or gel (available at most pharmacies)
- Fruit juice (e.g., orange juice)
- Regular (non-diet) soda
- Hard candies (e.g., glucose or dextrose candies)
- Honey or maple syrup (a teaspoon or two)
- A small serving of raisins or grapes
- Eat Simple Carbohydrates: Simple carbohydrates are broken down quickly by the body, providing a rapid source of glucose. Foods like white bread, white rice, or crackers can help raise blood sugar levels quickly.
- Consume a Snack: If a meal is not immediately available, eat a small snack that combines carbohydrates with a source of protein or fat to help stabilize blood sugar levels once they rise. Examples include a piece of fruit with peanut butter or cheese and crackers.
- Avoid Excessive Sugar: While it’s important to raise blood sugar levels quickly, avoid overindulging in sugary foods, as this can lead to a rapid increase followed by a crash in blood sugar.
- Monitor Your Blood Sugar: If you have a blood glucose monitor, check your levels before and after taking action to ensure they have returned to a safe range.
- Rest and Wait: After consuming carbohydrates, it’s essential to rest for a while and allow your body to absorb and use the glucose effectively.
- Inform Someone: If you are experiencing severe hypoglycemia and require assistance, make sure someone is aware of the situation and can help if needed.
- Consider Glucagon: In severe cases where you cannot consume carbohydrates orally (e.g., unconsciousness), glucagon injection may be necessary. Glucagon is a hormone that raises blood sugar levels and should be used as directed by a healthcare professional.
