Immediate Actions to Lower Blood Sugar
Managing blood sugar levels effectively requires a combination of long-term lifestyle adjustments and immediate actions that can help mitigate unexpected spikes. Here are three immediate proven strategies that can help bring down your blood sugar levels swiftly:
1. Take Insulin or Other Diabetes Medication
Insulin
The swiftest and most efficient approach to addressing hyperglycemia is to take rapid-acting insulin formulations, such as Humalog, Apidra, or Novolog. Rapid-acting insulins usually start kicking in 15 minutes but some may take up to an hour. Moreover, with type 1 diabetes, you may be able to additionally receive a correction dose via your insulin pump for prompt action.
Contrarily, slow-acting insulin variants like NPH do not exert immediate effects on reducing blood sugar levels. Their onset of action typically spans several hours, rendering them unsuitable for urgent scenarios demanding rapid glucose level drop.
After administering the insulin shot, closely monitor your blood sugar levels within 15-30 minutes to assess the rate of decline. However, be mindful that blood sugar levels may occasionally plummet too low, resulting in hypoglycemia. Therefore, it’s crucial to remain vigilant and seek professional guidance if necessary.
Moreover, refrain from injecting additional insulin too soon if your glucometer doesn’t decrease as rapidly as expected. Doing this otherwise could exacerbate your risk of hypoglycemia.
Other Diabetes Medications
- Metformin: Often the first medication prescribed for type 2 diabetes, metformin improves insulin sensitivity and reduces glucose production in your liver.
- Sulfonylureas: These medications help your body secrete more insulin.
- SGLT2 inhibitors and GLP-1 receptor agonists: These newer classes of medications can help lower blood sugar and have additional benefits for heart health and weight loss in some cases.
2. Sweat Away High Blood Sugar with Exercise
Staying active is the quickest method to bring down your blood sugar without medication. Exercise helps your body use insulin better and turns glucose into fuel. As your muscles work during physical activity, they grab glucose from your blood to use it for energy. This keeps your blood sugars stable for up to a whole day after exercising.
Optimal Exercise Regimens to Quickly Lower Blood Sugar
The current American Diabetes Association (ADA) guidelines recommend a mix of aerobics (like walking, swimming, or cycling) and resistance training (such as weightlifting) for managing glucose levels. According to the ADA, this integrated approach can yield maximal outcomes and prevent complications.
For aerobics:
The ADA recommends at least 150 minutes of moderate to vigorous exercise per week. Consistency is key—try to engage in at least 30 minutes of moderate activity most days of the week.
For Resistance training:
The ADA suggests doing resistance training 2 to 3 times a week, with 8 to 10 exercises. Each exercise should include 1 to 3 sets of 10 to 15 repetitions.
However, there’s an important consideration: It’s crucial to monitor blood sugar levels before and after exercise to prevent hypoglycemia, especially for individuals taking insulin or other blood sugar-lowering medications. This is due to the drop in blood sugar levels following any kind of exercise. This extra step helps you understand how your body responds to exercise and can guide you in managing high blood sugar in the future.
Moreover, if your blood sugar is significantly elevated, particularly above 240 mg/dL, you might not be a good candidate for exercise. In such cases, be sure to check for the presence of ketones. If ketone levels are high, it’s advisable to refrain from exercising, as it could further elevate your blood sugar and potentially lead to a fatal condition known as ketoacidosis (scroll below).
Also, remember that everyone’s body reacts differently to exercise, so what works for one may not work for the other. Hence, always consult your doctor for a more organized exercise regimen.
3. Keep Yourself Hydrated!
Hydration is pivotal in maintaining optimal health, extending to blood sugar management. Drinking sufficient water helps the kidneys flush out excess glucose through urine, lowering blood sugar levels. Moreover, staying hydrated helps maintain blood volume and improves blood circulation, improving insulin efficiency. Hence, choosing water or other zero-calorie drinks is advisable to avoid additional sugar intake.
4. Implement Stress Management Strategies
It’s no surprise how stress can negatively impact your blood sugar levels. It triggers the release of stress hormones like cortisol and adrenaline, which can raise blood sugar. Hence, it’s imperative to practice stress management techniques to keep your blood sugar levels in check, such as:
- Mindfulness and meditation: Engage in mindfulness practices and meditation. These techniques have been proven to alleviate stress and improve blood sugar control.
- Regular exercise: Physical activity not only benefits your overall health but also reduces stress and improves mental well-being.
- Adequate sleep: Getting enough quality sleep each night can help regulate hormones and mitigate stress levels, positively affecting blood sugar control.
- Hobbies and relaxation techniques: Participate in hobbies or relaxation activities such as deep breathing exercises, yoga, or spending time in nature. These practices can help relieve stress.
A 2018 study found that participating in social-related stress management training significantly improved blood sugar management in individuals with type 2 diabetes. Additionally, stress management techniques may positively impact glycated hemoglobin (HbA1c) levels.
5. Implement Fast-acting Dietary Choices
Certain foods and drinks can influence blood sugar levels more quickly than others. Incorporating these into your diet, especially after a higher-carb meal, can help manage spikes:
| Dietary Choices | Effect on Blood Sugar Levels | Tips |
| Apple Cider Vinegar (ACV) | Helps lower blood sugar levels when taken before or after meals. Mixing a tablespoon of ACV in a 6 oz glass of filtered water can improve insulin sensitivity and slow the rise in blood sugar after eating. This effect is attributed to acetic acid, which may influence your body’s response to carbohydrates and improve insulin response. | Sip through a straw to prevent damage to tooth enamel. |
| Fiber-rich foods | Foods high in fiber, such as vegetables, whole grains, and legumes, slow down the digestion of carbohydrates and the absorption of sugar, helping to regulate blood sugar spikes. | Eat fiber before consuming carbs to slow their digestion |
| Lean protein | Incorporating lean protein sources like chicken, fish, and tofu in your meals can help stabilize blood sugar levels by slowing digestion and preventing rapid spikes. They promote satiety without significantly impacting blood sugar levels. | It’s crucial that protein complements vegetables, fruits, and whole grains rather than being the sole component in a meal. |
| Healthy fats | Foods packed with healthy fats, such as fatty fish, avocados, nuts, seeds, and olive oil, can help slow the glucose absorption into your bloodstream. This results in a more gradual rise in blood sugar and improved insulin sensitivity. | |
| Cinnamon | Adding cinnamon to your diet can help lower blood sugar levels. This spice has been shown to improve insulin sensitivity and decrease blood sugar levels after meals. |
These quick-acting dietary choices can be effective in managing blood sugar, particularly after consuming a higher-carb meal. However, they should be part of a broader approach to blood sugar management for individuals with diabetes, which includes regular monitoring, lifestyle changes, and medication when necessary. Always consult with a healthcare professional for personalized advice.
6. Explore Supplement Options with your Doctor
Supplements for diabetes are not standalone solutions. They work best when combined with conventional treatments such as medication, diet, and exercise. While they cannot replace these primary treatments, certain supplements have shown promising potential in helping manage blood sugar values and minimizing the risk of diabetes-related complications.
- Cinnamon: Known to improve insulin sensitivity, delay stomach emptying, and lower blood sugar levels.
- Alpha-lipoic acid: An antioxidant that can improve insulin sensitivity and may help relieve symptoms of nerve damage in people with diabetes.
- Chromium: May enhance insulin action, although research is mixed, and high doses can be harmful.
- Berberine: Found in several plants, berberine has been shown to improve insulin sensitivity and lower blood sugar levels, comparable to some diabetes medications.
- Vitamin B1 (Thiamine): Thiamine is crucial for energy metabolism and the proper function of cells. It plays a significant role in the metabolism of glucose in the body. Individuals with diabetes often have lower levels of thiamine in their blood, which can impair glucose metabolism and potentially raise blood sugar levels. Supplementation with thiamine has been shown to improve glucose metabolism, reduce blood sugar levels, and prevent complications associated with diabetes. Thiamine is also essential for nerve health, which can be beneficial since diabetic neuropathy is a common complication of diabetes.
Consult with a healthcare provider before starting any new supplement, as some can interact with medications or may not be appropriate for everyone. Healthcare providers can offer personalized advice on supplement use and dosage to complement your diabetes management plan.
Interpreting Your Blood Sugar Levels
Blood sugar readings can vary based on several factors, including time of day, recent meals, exercise, and stress levels. Understanding how to interpret these readings and when to seek medical advice is crucial.
Let’s break down the different types of blood sugar testing and their meanings.
There are three blood sugar tests: fasting, postprandial, and bedtime. The American Diabetes Association (ADA) recommends sets recommended blood sugar targets for both individuals with and without diabetes:
| Blood Sugar Type | Definition | Individuals without Diabetes | Individuals with Diabetes |
| Fasting blood sugar | Blood glucose level after an overnight fast. Reflects your body’s glucose management without recent food intake. | 70 – 99 mg/dL | 80 – 130 mg/dL (4.0-7.0 mmol/L) |
| Postprandial blood sugar | Blood glucose level measured approximately two hours after eating. Indicates how the body processes glucose in response to food intake. | < 140 mg/dL | < 180 mg/dL (10 mmol/L) |
| Bedtime | Blood glucose level monitored before bedtime to ensure stability overnight, minimizing the risk of nocturnal hypoglycemia* and early morning hyperglycemia* | N/A | 100 – 140 mg/dL (5.6-7.8 mmol/L) |
*Nocturnal hypoglycemia refers to low blood sugar at night, potentially leading to severe consequences if left untreated. Symptoms may include sweating, confusion, nightmares, and seizures.
*Early morning hyperglycemia, also known as the dawn phenomenon, refers to elevated blood sugar levels in the early morning, typically between 3:00 AM and 8:00 AM, in individuals with diabetes. Natural hormonal changes during the early morning hours, particularly increased secretion of hormones that counteract insulin, primarily drive this phenomenon.
In general, a blood glucose level of 180 mg/dL is considered too high.
Remember that individual targets may vary based on health conditions and medical history. Always consult with a healthcare professional to determine your personalized blood sugar goals.
Importance of Regular Blood Sugar Monitoring
Regular blood sugar monitoring is a cornerstone of diabetes management. It provides a snapshot of how well your diabetes management plan is working, offering immediate feedback on the need for adjustments.
The key benefits include:
- Immediate feedback: Helps determine whether your blood sugar is too high, too low, or within the target range, allowing you to take timely action as needed.
- Trend analysis: Identifies patterns that may necessitate adjustments in your management plan.
- Prevention of complications: By empowering you to make informed decisions about your diet, exercise, and medications, regular monitoring can help avoid both short-term complications, like hypoglycemia (low blood sugar), and long-term complications, such as neuropathy, retinopathy, and cardiovascular disease.
Early Symptoms and Complications of Hyperglycemia
Identifying the symptoms of hyperglycemia at an early stage can enable prompt intervention and management. For instance, if someone experiences excessive thirst, they can focus on hydration and blood sugar management.
Early symptoms of hyperglycemia
The early indicators of hyperglycemia include:
- Frequent urge to pee
- Increased thirst
- Increased hunger
- Headaches
- Difficulty concentrating
- Blurred vision
Complications of Hyperglycemia
If left untreated, hyperglycemia can lead to ketoacidosis and various long-term complications, including cardiovascular disease, nerve damage, kidney failure, eye problems, and foot ulcers.
For ketoacidosis, be sure to watch for the following symptoms:
- Fruity smelling breath
- Nausea and vomiting
- Abdominal cramps
- Shortness of breath
- Confusion
- Loss of consciousness
It’s imperative to spot the symptoms of hyperglycemia on time to prevent or delay the risk of diabetes-related complications and maintain overall health and well-being.
When to Seek Medical Advice?
It’s crucial to consult with a healthcare provider if you:
- Have frequent high readings: Consistently high readings despite following your diabetes management plan.
- Notice symptoms of hypoglycemia: Dizziness, sweating, confusion, or shaking, especially if your readings are below 70 mg/dL (3.9 mmol/L).
- Notice symptoms of hyperglycemia: Including excessive thirst, frequent urination, blurred vision.
