What Blood Sugar Levels Are Too Low: Understanding Hypoglycemia
What Blood Sugar Levels Are Too Low – Hypoglycemia is a medical condition that occurs when the blood sugar levels drop too low, below the normal range of 70 to 99 milligrams per deciliter (mg/dL). Blood sugar, also known as glucose, is the body’s primary source of energy. It comes from the food we eat and is transported to our cells through the bloodstream. Insulin, a hormone produced by the pancreas, helps regulate the amount of glucose in the blood.
When the blood sugar levels drop too low, the body’s cells do not receive enough energy to function properly, which can lead to a variety of symptoms. This can happen when there is an imbalance between the amount of glucose in the blood and the amount of insulin being produced. In some cases, hypoglycemia can occur in people who do not have diabetes, but it is more common in those with diabetes who take insulin or other medications to lower their blood sugar levels.
Symptoms of hypoglycemia can vary depending on how low the blood sugar levels are and how quickly they drop. Common symptoms include shakiness or trembling, sweating, dizziness or lightheadedness, confusion or difficulty concentrating, blurred vision, headache, fatigue or weakness, irritability or mood changes, rapid heartbeat, anxiety or nervousness, hunger or nausea. In severe cases, hypoglycemia can cause seizures or loss of consciousness.

It is important to understand the causes, symptoms, and treatment options for hypoglycemia to prevent future episodes and seek medical care if necessary. If you are experiencing symptoms of hypoglycemia, speak with your healthcare provider for an accurate diagnosis and treatment plan.
What Causes Hypoglycemia, and What Blood Sugar Levels is Too Low?
Hypoglycemia can occur for a variety of reasons, including:
- Skipping meals or not eating enough
Skipping meals or not eating enough can lead to hypoglycemia, especially in people with diabetes who take insulin or other blood sugar-lowering medications. When a person skips a meal or does not eat enough, there may not be enough glucose in the blood to supply the body’s cells with the energy they need. This can cause the blood sugar levels to drop too low, resulting in hypoglycemia.
To prevent hypoglycemia caused by skipping meals or not eating enough, it is important to follow a healthy meal plan that includes regular meals and snacks. This can help ensure that the body has a steady supply of glucose throughout the day. People with diabetes should work with a healthcare provider or a registered dietitian to develop a meal plan that is tailored to their individual needs and lifestyle.
In addition to following a healthy meal plan, people with diabetes who are at risk for hypoglycemia should monitor their blood sugar levels regularly. This can help them identify when their blood sugar levels are too low and take appropriate action, such as eating a snack or adjusting their medication dosage.
If you are experiencing symptoms of hypoglycemia, such as shakiness, sweating, or confusion, it is important to treat the low blood sugar levels immediately. This can be done by consuming a source of fast-acting carbohydrates, such as fruit juice, candy, or glucose tablets. Once the blood sugar levels have returned to normal, it may be necessary to adjust the meal plan or medication dosage to prevent future episodes of hypoglycemia.
Overall, understanding what blood sugar levels are too low and how to prevent and treat hypoglycemia is essential for people with diabetes and anyone at risk for this condition. By following a healthy meal plan, monitoring blood sugar levels regularly, and taking appropriate action when necessary, people can manage their blood sugar levels and reduce the risk of hypoglycemia.
- Taking too much insulin or other diabetes medication
Taking too much insulin or other diabetes medication can cause blood sugar levels to drop too low, resulting in hypoglycemia. Insulin and other diabetes medications are used to help lower blood sugar levels in people with diabetes. However, if too much medication is taken, it can cause the blood sugar levels to drop below the normal range, leading to hypoglycemia.
To prevent hypoglycemia caused by taking too much insulin or other diabetes medication, it is important to follow the medication instructions carefully. This may include monitoring blood sugar levels regularly, adjusting medication dosages as needed, and timing medication doses to coincide with meals and physical activity. People with diabetes should work closely with their healthcare provider to develop an individualized treatment plan that takes into account their medical history, lifestyle, and other factors that may affect their blood sugar levels.
If a person with diabetes experiences symptoms of hypoglycemia, such as shakiness, confusion, or sweating, they should check their blood sugar levels immediately. If the levels are too low, they should consume a source of fast-acting carbohydrates, such as fruit juice or candy, to help raise their blood sugar levels. In some cases, it may be necessary to seek medical attention if the symptoms are severe or if the blood sugar levels do not return to normal after consuming fast-acting carbohydrates.
Overall, understanding what blood sugar levels are too low and how to prevent and treat hypoglycemia is essential for people with diabetes who take insulin or other blood sugar-lowering medications. By following medication instructions carefully, monitoring blood sugar levels regularly, and taking appropriate action when necessary, people can manage their blood sugar levels and reduce the risk of hypoglycemia.
- Exercising More than Usual
Regular physical activity is an important part of a healthy lifestyle, especially for people with diabetes. However, exercising more than usual can sometimes cause blood sugar levels to drop too low, leading to hypoglycemia. When a person exercises, their body uses glucose for energy. If there is not enough glucose in the blood to supply the body’s cells with the energy they need during exercise, the blood sugar levels can drop too low, resulting in hypoglycemia.
To prevent hypoglycemia caused by exercising more than usual, it is important to monitor blood sugar levels regularly and adjust medication dosages and/or food intake as needed. People with diabetes who exercise regularly should work with a healthcare provider or a certified diabetes educator to develop an individualized plan for managing their blood sugar levels during exercise. This may include checking blood sugar levels before and after exercise, eating a snack before exercising, and adjusting medication dosages as needed.
If a person with diabetes experiences symptoms of hypoglycemia during or after exercise, such as shakiness, confusion, or sweating, they should check their blood sugar levels immediately. If the levels are too low, they should consume a source of fast-acting carbohydrates, such as fruit juice or candy, to help raise their blood sugar levels. It is also important to remember to stay hydrated during exercise, as dehydration can affect blood sugar levels.
Overall, understanding what blood sugar levels are too low and how to prevent and treat hypoglycemia during exercise is important for people with diabetes who are physically active. By monitoring blood sugar levels regularly, adjusting medication dosages and/or food intake as needed, and taking appropriate action when necessary, people can manage their blood sugar levels and reduce the risk of hypoglycemia during exercise.
- Drinking alcohol without eating enough food
Drinking alcohol can cause blood sugar levels to drop, especially if the person is not eating enough food. When a person drinks alcohol, their liver works to remove the alcohol from their bloodstream, which can affect the liver’s ability to release glucose into the bloodstream. If a person does not have enough glucose in their bloodstream to begin with, drinking alcohol can cause their blood sugar levels to drop too low, resulting in hypoglycemia.
To prevent hypoglycemia caused by drinking alcohol without eating enough food, it is important to consume food while drinking and to monitor blood sugar levels regularly. People with diabetes who drink alcohol should be aware of the potential effects on their blood sugar levels and take precautions to prevent hypoglycemia. This may include eating a meal or snack before drinking, consuming alcoholic beverages in moderation, and checking blood sugar levels before and after drinking.
If a person with diabetes experiences symptoms of hypoglycemia while drinking alcohol, such as shakiness, confusion, or sweating, they should check their blood sugar levels immediately. If the levels are too low, they should consume a source of fast-acting carbohydrates, such as fruit juice or candy, to help raise their blood sugar levels. It is also important to remember to stay hydrated while drinking alcohol, as dehydration can affect blood sugar levels.
Overall, understanding what blood sugar levels are too low and how to prevent and treat hypoglycemia while drinking alcohol is important for people with diabetes. By consuming food while drinking, monitoring blood sugar levels regularly, and taking appropriate action when necessary, people can manage their blood sugar levels and reduce the risk of hypoglycemia while enjoying alcoholic beverages.
- Certain medical conditions, such as liver disease or hormonal imbalances
In addition to lifestyle factors such as skipping meals, taking too much insulin, exercising more than usual, and drinking alcohol without eating enough food, certain medical conditions can also lead to hypoglycemia. These conditions may affect the body’s ability to regulate blood sugar levels and can cause blood sugar levels to drop too low, resulting in hypoglycemia.
Liver disease, for example, can affect the liver’s ability to release glucose into the bloodstream, which can lead to low blood sugar levels. Hormonal imbalances, such as an excess of insulin or a deficiency of glucagon, can also affect blood sugar levels and cause hypoglycemia.
If a person with diabetes has a medical condition that puts them at risk for hypoglycemia, it is important to work with a healthcare provider to develop an individualized plan for managing their blood sugar levels. This may include adjusting medication dosages, monitoring blood sugar levels more frequently, and making lifestyle changes to help prevent hypoglycemia.
If a person experiences symptoms of hypoglycemia as a result of a medical condition, such as liver disease or a hormonal imbalance, they should seek medical attention immediately. Treatment may include adjusting medication dosages or addressing the underlying medical condition.
Overall, understanding what blood sugar levels are too low and the potential causes of hypoglycemia, including certain medical conditions, is important for people with diabetes. By working with a healthcare provider to develop an individualized plan for managing their blood sugar levels, people can reduce the risk of hypoglycemia and maintain optimal health.
- Certain medications, such as beta-blockers or sulfonylureas: Understanding What Blood Sugar Levels Are Too Low
Certain medications can also cause hypoglycemia as a side effect. Beta-blockers, which are commonly used to treat high blood pressure and heart disease, can mask the symptoms of hypoglycemia by slowing the heart rate and suppressing the body’s ability to release glucose into the bloodstream. This can make it more difficult for a person to recognize when their blood sugar levels are too low.
Sulfonylureas, which are oral medications used to treat type 2 diabetes, work by stimulating the pancreas to release more insulin. While this can help lower blood sugar levels, it can also cause hypoglycemia if too much insulin is released or if a person does not eat enough food after taking the medication.
If a person is taking medication that puts them at risk for hypoglycemia, it is important to work with a healthcare provider to monitor blood sugar levels regularly and adjust medication dosages as needed. It is also important to be aware of the signs and symptoms of hypoglycemia and to take precautions to prevent low blood sugar levels, such as consuming regular meals and snacks and avoiding excessive alcohol consumption.
If a person experiences symptoms of hypoglycemia while taking medication, they should check their blood sugar levels immediately and consume a source of fast-acting carbohydrates, such as fruit juice or candy, to help raise their blood sugar levels. It is also important to seek medical attention if hypoglycemia is a recurring problem or if blood sugar levels cannot be stabilized with medication adjustments.
Overall, understanding what blood sugar levels are too low and the potential side effects of certain medications is important for people with diabetes. By working with a healthcare provider to develop an individualized plan for managing their blood sugar levels, people can reduce the risk of hypoglycemia and maintain optimal health.
What are the Symptoms of Hypoglycemia?
The symptoms of hypoglycemia can vary depending on how low the blood sugar levels are and how quickly they drop. Common symptoms include:
-
- Shakiness or trembling
- Sweating
- Dizziness or lightheadedness
- Confusion or difficulty concentrating
- Blurred vision
- Headache
- Fatigue or weakness
- Irritability or mood changes
- Rapid heartbeat
- Anxiety or nervousness
- Hunger or nausea
- In severe cases, hypoglycemia can cause seizures or loss of consciousness.
How is Hypoglycemia Diagnosed?
If you suspect that you may have hypoglycemia, it is important to see a healthcare professional for an accurate diagnosis. Your doctor will likely perform a physical exam and order blood tests to measure your blood sugar levels.
To diagnose hypoglycemia, a healthcare provider will typically use a glucose meter to measure the amount of glucose in a person’s blood. If a person’s blood sugar levels are below 70 mg/dL and they are experiencing symptoms of hypoglycemia, such as dizziness, sweating, or confusion, they may be diagnosed with hypoglycemia.
However, it is important to note that some people with diabetes may not experience symptoms of hypoglycemia until their blood sugar levels drop much lower than 70 mg/dL. This is known as hypoglycemia unawareness and can be a dangerous complication of diabetes. In these cases, a healthcare provider may perform a test called continuous glucose monitoring (CGM) to track a person’s blood sugar levels over a period of time and determine if they are experiencing hypoglycemia.
In addition to blood tests and glucose monitoring, a healthcare provider may also perform other tests to determine the underlying cause of a person’s hypoglycemia. This may include tests to check for hormonal imbalances or liver disease, as well as a review of a person’s medication regimen to identify any drugs that may be causing hypoglycemia.
Overall, if you suspect that you may have hypoglycemia, it is important to seek medical attention and receive an accurate diagnosis. With prompt diagnosis and appropriate treatment, people with hypoglycemia can manage their blood sugar levels and reduce the risk of complications.
What are the Treatment Options for Hypoglycemia?
The treatment for hypoglycemia depends on the underlying cause and the severity of the symptoms. In mild cases, eating or drinking something that contains sugar, such as fruit juice or a piece of candy, can quickly raise blood sugar levels and alleviate symptoms. This is known as treating hypoglycemia with fast-acting carbohydrates.
For more severe cases of hypoglycemia, such as those that occur in people with diabetes who are taking insulin or other diabetes medications, emergency medical attention may be necessary. In these cases, a healthcare provider may administer a glucagon injection or provide intravenous glucose to rapidly raise a person’s blood sugar levels.
If hypoglycemia is a recurring problem, your doctor may recommend changes to your diet, medication, or exercise routine. In some cases, medication adjustments may be necessary to prevent future episodes. For example, a healthcare provider may adjust the dosage of insulin or other diabetes medications to prevent blood sugar levels from dropping too low.
In addition to medication adjustments, lifestyle changes can also be effective in preventing hypoglycemia. This may include eating regular meals and snacks throughout the day, monitoring blood sugar levels frequently, and avoiding alcohol without eating enough food. In some cases, a healthcare provider may recommend a continuous glucose monitoring (CGM) device to track blood sugar levels in real time and alert a person if their levels drop too low.
Overall, it is important to work closely with a healthcare provider to manage hypoglycemia and prevent future episodes. With proper treatment and lifestyle changes, people with hypoglycemia can maintain healthy blood sugar levels and reduce the risk of complications associated with low blood sugar levels. By understanding and recognizing the symptoms of hypoglycemia, individuals can take steps to prevent this condition and maintain optimal health.
When is Hypoglycemia an Emergency?
In some cases, hypoglycemia can be a medical emergency that requires immediate treatment. You should seek emergency medical care if you experience:
-
- Severe confusion or difficulty speaking
- Loss of consciousness or seizures
- Inability to swallow or breathe
- Chest pain or shortness of breath
- Weakness or paralysis on one side of the body
