You've likely heard of hypoglycemia as low blood sugar or low blood glucose levels. Although it's typically associated with people who have diabetes, it's a condition that anyone can experience. While it's not a disease per se, it can indicate health issues, so it's crucial to stay on top of it. You should know enough about the condition so you're aware of the symptoms, what can cause it, and what you can do to prevent it from happening. Read on to find out all this and more!
Before we walk through the signs and symptoms, it's essential to understand what this condition is. Hypoglycemia, or low blood sugar, is a condition that people experience when blood sugar reduces to dangerously low levels. This is the opposite event of hyperglycemia or high blood sugar.
While it's normal for glucose values to rise and fall, extremely low blood sugar can cause adverse side effects. And, while you can track some of the symptoms of hypoglycemia, they usually vary depending on the individual and the severity of how the body handles the glucose reduction.
Since not everyone has the same symptoms of hypoglycemia, it's not always easy to pinpoint when you're experiencing them. There are also varying levels of severity for these symptoms and a difference in severity in the condition itself. There's hypoglycemia, and then there's severe hypoglycemia.
Severe hypoglycemia occurs when blood glucose values drop so low that you require assistance administering either medication or fast-acting carbohydrates. You can alleviate these hypoglycemic symptoms (and often even prevent them) in less severe cases through simple diet and lifestyle modifications.
It's always a good idea to be aware of all the possible symptoms so you can address them before they become an issue. Whenever you experience the following, consider noting down the occurrence and severity so you can keep track:
Now that we've taken a look at the signs and symptoms, we're sure you're wondering what causes them. Is it unhealthy food choices? What about your routine and lifestyle choices? Does medication affect your levels too? It can be challenging to keep track of everything going into your body. Still, an easy way to do this is to get a continuous glucose monitor to see what your body is reacting to in real-time. In the meantime, here are some of the most common causes of the condition to focus on:
There are many reasons why hypoglycemia may occur among people who don't have diabetes. One of the most common causes is something called reactive hypoglycemia. It occurs after a meal that is typically high in refined carbohydrates. In these cases, your body overproduces the amount of insulin that it needs to process the meal, which results in your glucose dipping too low. Reactive hypoglycemia may be an early sign that you're at a higher risk of developing diabetes.
Many types of medication can cause hypoglycemia, especially if you have diabetes. For example, if someone with diabetes takes too much of their insulin or other diabetic medications, it can cause hypoglycemic events. While medication-induced hypoglycemia is less common among those without diabetes, it's still a risk if you're taking certain medicines. Here's a list of drugs that are known to cause drug-induced hypoglycemia:
If you have questions about any of the drugs you’re taking and whether they put you at risk of hypoglycemia, it’s best to discuss them with your medical provider.
If you've been fasting when you consume alcohol, or you have a history of alcohol abuse, liquor will increase your risk of developing hypoglycemia. As with most other factors, it's more of a risk for those with diabetes, but those who don't have diabetes are not in the clear here.
So, why does alcohol affect this condition so much, and how? The primary cause of alcohol-induced hypoglycemia is the inhibition of gluconeogenesis, or the creation of glucose from non-carbohydrate substrates. Alcohol may potentially increase endogenous insulin secretion, contributing to the risk of hypoglycemic events in some individuals.
Several key organs play a role in glucose regulation. If you have a history of kidney, liver, or heart issues, this may disrupt glucose regulation and increase your risk of experiencing hypoglycemia. Let's break this down a little more:
Kidneys: Your kidneys play a vital role in glucose homeostasis. They're responsible for a hose of processes including gluconeogenesis, glucose filtration, glucose reabsorption, and glucose uptake. Some studies have found that the kidneys are responsible for about 20% of glucose production via gluconeogenesis.
Liver: Your liver plays a vital role in multiple glucose homeostasis pathways, including glycolysis, gluconeogenesis, glycogenesis, and glycogenolysis.
Heart: We don't always think of the heart as a glucose regulator, but the circulatory system plays a significant role in blood glucose regulation. Hormones such as glucagon are carried via blood, which then signals other organs to regulate blood glucose. If there is any damage to the circulatory system, it can negatively impact your health.
There's no doubt diet plays a distinct role when it comes to hypoglycemia. Unbalanced diets that are higher in refined carbs (candy, crackers, sugar-sweetened beverages) and low in protein and fat are often associated with hypoglycemic events and 'energy crashes.'
On another note, if someone is fasting or skipping meals, the body may not be able to handle long periods without incoming carbohydrates. People who don't have diabetes but struggle with frequent hypoglycemic events may want to focus on increasing their metabolic flexibility as a long-term preventive plan.
Hypoglycemia during pregnancy is more common than you'd think. It often occurs during the first trimester, when nausea and vomiting are most prevalent. However, it can also occur at any time during a pregnancy. During this time, a growing baby requires constant glucose and will siphon as much as they need from the mother. For this reason, eating frequent meals, maintaining a balanced diet, and replenishing those glucose stores are essential to help you prevent the condition.
By now, we know what hypoglycemia is, what the symptoms are, and the causes to watch out for. And we also know that it's not a condition that only those with diabetes experience. But are there any other risk factors? Are some people more at risk than others? Here's what you need to know:
Obesity is a complex health condition that's linked to insulin resistance. People with insulin resistance may have imbalanced hormones, making it difficult for their bodies to maintain normal glucose levels endogenously. High insulin levels, which often occur among insulin-resistant people, may lead to low glucose drops during fasting times.
Yes, a family history of diabetes does put you at a higher risk of developing pre-diabetes and experiencing hypoglycemia. Learning more about your family's health history (specifically related to diabetes) can provide great insights into whether you should get a diabetes screening. Taking preventive measures to ensure that your glucose values are in an optimal range will also help reduce your risk of diabetes.
People who have undergone bariatric surgery often have a higher risk of hypoglycemia, reactive hypoglycemia, and hyperglycemia. This is because of dumping syndrome and reduced stomach size. Dumping syndrome, or the rapid emptying of the contents of your stomach, can lead to excessively high and low glucose values. Reactive hypoglycemia is also very common and is thought to be caused by hyperinsulinemia and an altered GLP-1 response.
Pre-diabetes means that your blood glucose is above the normal range, but below the diabetic range. When your glucose values see an elevation over a long period, your pancreas will secrete insulin to help lower these values. Circulating insulin allows glucose to enter the cells, which will help blood glucose values decrease. When your glucose values drop, your pancreas slows down the production of insulin. For those who have pre-diabetes, this process does not work as well as it should. Eventually, this leads to an overproduction of insulin and poor glucose regulation.
Diagnosing and treating hypoglycemia typically involves three steps that your doctor will likely need to help you out with. These include measuring low blood glucose, pinpointing the symptoms of hypoglycemia, and finally, finding relief from the symptoms by treating the hypoglycemia. There are two primary tests that your doctor can do to diagnose hypoglycemia.
You may need to undergo a fasting test since hypoglycemia can occur in a fasted state (long periods without eating). During this test, you would fast overnight or up to 72 hours. Your blood will be drawn at different times during this period to measure your blood glucose levels. If you see blood glucose values of <55 mg/dL with symptoms, you likely have hypoglycemia.
Talk to your medical provider about the testing before you decide. Ideally, you should undergo the tests when you experience the symptoms, but this isn't always possible. In some situations, you can also receive these tests during a prolonged fasting state under the supervision of a health professional.
Another test to diagnose hypoglycemia is a mixed-meal tolerance test. This is a good option for people who experience reactive hypoglycemia, or hypoglycemia symptoms, after a meal. It's important to note that this test is not well standardized.
Typically, the test is performed after an overnight fast. In the morning, you're given a meal that's similar to one that triggers hypoglycemic symptoms. A medical professional will observe you for several hours while labs are drawn every 30-60 minutes for a total period of five hours. Similar to fasting tests, your physician orders all labs.
Understanding the root cause of your hypoglycemia will help you prevent these events from occurring. So, when you're creating a preventive plan with a healthcare professional, address every factor, including medication, diet, exercise, your health history, and your family's health history. Here are some other changes you can incorporate into your routine to prevent the condition:
One of the leading causes of hypoglycemia among people who don't have diabetes is going without food for extended periods. To help prevent hypoglycemic episodes, eating smaller, more frequent meals will help. In addition to meal timing, meal content also plays a significant role. Make sure you include protein, natural fat, and non-starchy carbohydrates in every meal you eat. Here are some examples to help you start planning your meals:
Breakfast: A spinach-and-egg omelet cooked in grass-fed butter, with a handful of berries on the side.
Lunch: Wild tuna with olive oil, sesame seeds, almond crackers, chopped raw veggies, and a handful of raspberries.
Snack: An apple with almond butter.
Dinner: Grilled chicken with sweet potatoes along with an arugula and cherry tomato salad drizzled over with olive oil.
It's also a good idea to know what to do to correct things as soon as you experience symptoms of hypoglycemia. An easy fix is to immediately consume 15 grams of fast-acting carbohydrates. These can include:
While these foods are a helpful way to correct hypoglycemic symptoms, you shouldn't make them a regular part of your diet. For good long-term health, it's best to focus on prevention and avoid consuming too much of these high-sugar foods. Remember that even if you have a set diet plan for every meal of the day, you should keep healthy snacks on hand. This way, you're not reaching for anything too unhealthy when you feel hungry in between meals. This will help avoid hypoglycemic episodes and keep you healthier. Here's a good starter list of healthy snacks:
