How To Lower A1C Quickly Before Blood Test?

If you have recently been asked to take a blood test for A1C levels, you may be wondering what you can do to lower your levels quickly. A1C is a blood test that measures your average blood sugar levels over the past two to three months. This test is commonly used to diagnose diabetes and monitor the effectiveness of treatment. High A1C levels can increase your risk of developing diabetes complications, such as heart disease, nerve damage, and kidney problems. Fortunately, there are several lifestyle changes and natural remedies that can help lower your A1C levels quickly and effectively. In this article, we will discuss some of the most effective methods for lowering A1C levels before your next blood test.

1. Understanding A1C and Why It Matters for Your Health

Before we dive into the strategies to lower your A1C levels quickly, let’s first understand what A1C is and why it is important for your health. A1C or glycated hemoglobin is a blood test used to measure your average blood glucose levels over the past 2-3 months. This test is commonly used to diagnose diabetes and monitor blood sugar levels in people diagnosed with diabetes.

But why does it matter? High A1C levels indicate poor blood sugar control, which can increase the risk of developing diabetes-related complications like nerve damage, kidney disease, heart disease, and stroke. Keeping your A1C levels within a healthy range can reduce the risk of these complications significantly.

According to the American Diabetes Association, the recommended A1C target for most people with diabetes is less than 7%. However, your doctor might recommend an individualized target based on your medical history, age, and other health conditions.

Now that we understand the significance of A1C levels, let’s explore the strategies to lower them quickly before your next blood test.

2. Diet Modifications: Foods to Include and Avoid to Lower A1C

Maintaining a healthy and balanced diet is crucial for managing blood sugar levels and lowering A1C. By making smart food choices, you can significantly reduce the risk of developing complications related to diabetes such as kidney disease, nerve damage, and eye problems. Below are some dietary modifications that can help you lower A1C before a blood test.

Foods to Include:

Include high-fiber foods in your diet such as fruits, vegetables, legumes, and whole grains. These foods are slowly digested and absorbed, causing a gradual rise in blood sugar levels. Soluble fibers, in particular, bind to sugar and help to eliminate it from your body, reducing blood sugar spikes. You can also incorporate lean proteins such as chicken, fish, and tofu, and healthy fats from sources such as avocado, nuts, and olive oil.

Foods to Avoid:

Avoid high-carbohydrate, high-sugar, and processed foods. These types of foods are rapidly digested and absorbed causing a sharp increase in blood sugar levels. Examples of these foods include white bread, pasta, rice, sugary drinks, candies, cakes, and cookies. Additionally, trans-fats found in fried foods, margarine, and processed snacks can worsen insulin resistance and increase A1C levels.

Making healthy food choices can go a long way in managing diabetes and lowering A1C levels. Consult with a registered dietitian or a diabetes educator to guide you in creating a personalized meal plan that is suitable for your dietary preferences and lifestyle.

3. The Role of Exercise in A1C Reduction and Blood Sugar Management

How To Lower A1C Quickly Before Blood Test

Exercise is an essential part of diabetes management. It helps to improve insulin sensitivity, promote weight loss, and reduce blood sugar levels, which can help to lower your A1C quickly. When you exercise, your muscles use glucose as a source of energy, reducing the amount of glucose in your bloodstream. This effect is long-lasting and can last up to 24 hours after exercise.

There are various types of exercises you can do to help reduce your A1C, including cardio exercises, strength training, and high-intensity interval training (HIIT). Cardio exercises like walking, jogging, cycling, or swimming can help to improve cardiovascular health and control blood sugar levels. Strength training helps to build muscles, which can help to burn more calories and improve insulin sensitivity. HIIT workouts involve performing short bursts of intense activity followed by periods of rest, which can help to improve insulin sensitivity and burn fat.

It is important to note that exercise intensity and duration can affect blood sugar levels. If you are starting an exercise program, it is essential to start slow and gradually increase the intensity and duration. Check your blood sugar levels before and after exercising to determine how your body responds to exercise. Speak with your doctor to determine the best exercise program for you and your individual needs.

Here are some tips to help you get started with exercise:

  • Start with low-intensity exercises like walking and gradually increase intensity and duration
  • Include a variety of exercises in your routine, including cardio and strength training
  • Try HIIT workouts for a quick and challenging workout
  • Monitor your blood sugar levels before and after exercising
  • Drink plenty of water to stay hydrated during exercise

The Bottom Line

Exercise is an important way to manage blood sugar levels and lower A1C quickly. Include a variety of exercises in your routine, gradually increase intensity and duration, and consult with your doctor before beginning any new exercise program. Remember to monitor your blood sugar levels before and after exercising and stay hydrated.

4. Lifestyle Changes: Stress Management, Sleep Habits, and Hydration

Managing stress, having quality sleep, and staying sufficiently hydrated are important lifestyle changes that can help lower A1C levels. Being proactive in addressing these factors can help manage blood sugar levels and improve overall health.

Stress Management

Stress can lead to increased blood sugar levels as it triggers the release of cortisol one of the stress hormones produced by the adrenal gland. Stress management is, therefore, essential in controlling A1C levels. Some helpful stress management techniques include deep breathing, yoga, meditation, guided imagery, and progressive muscle relaxation. It would be best to incorporate these stress management techniques into your daily routine, taking short breaks throughout the day to reduce stress levels actively.

Sleep Habits

Getting enough quality sleep every night can have a significant impact on glucose levels. Poor sleep habits can lead to insulin resistance, causing higher blood sugar levels. It’s generally recommended that adults have at least 7-9 hours of sleep every night and try to maintain consistent sleep habits, such as waking and sleeping at the same time each day. It’s also important to create an ideal sleeping environment, including keeping your room dark, cool, and quiet, and avoiding the use of electronic devices before bed.


Staying well hydrated can help regulate blood sugar levels. When you are dehydrated, your blood sugar levels can become concentrated, leading to higher A1C levels. Drinking enough water throughout the day is essential in preventing dehydration. Additionally, reducing or avoiding flavored drinks, including sodas and sports drinks, is recommended. Instead, opt for plain water or sugar-free flavored water. It would be best to aim for at least eight glasses of water per day and increase water intake during exercise or exposure to hot or humid conditions.

Incorporating stress management, quality sleep habits, and hydration is essential in reducing the risk of higher A1C levels. These lifestyle changes can help individuals manage their blood sugar levels, prevent long-term complications, and improve overall health.

5. Supplements and Medications That Can Help Lower A1C

Supplements and medications can aid in lowering A1C levels. However, it is essential to consult with a healthcare professional before incorporating any medication or supplement into your routine. Below are some of the levels.


1. Probiotics: Probiotics can improve your gut health, enhance insulin sensitivity, and reduce inflammation, thereby lowering A1C levels. Foods such as yogurt, kefir, and kimchi contain probiotics.

2. Alpha-lipoic acid (ALA): ALA, an antioxidant, enhances insulin sensitivity, reduces inflammation, and lowers blood sugar levels, leading to decreased A1C levels. Foods such as spinach, broccoli, and beef liver contain ALA.

3. Chromium: Chromium, a trace mineral, plays a key role in improving insulin sensitivity, which helps lower blood sugar levels. Foods such as broccoli, grape juice, and potatoes contain chromium.


1. Metformin: Metformin is a commonly used medication to treat type 2 diabetes. It works by decreasing glucose production in the liver, improving insulin sensitivity, and enhancing glucose uptake in muscle cells, thus lowering A1C levels.

2. Sulfonylureas: Sulfonylureas are a class of medications that stimulate the pancreas to produce more insulin, leading to lower blood sugar levels and reduced A1C.

3. DPP-4 inhibitors: DPP-4 inhibitors block the action of an enzyme that breaks down a hormone in the gut that stimulates insulin secretion, leading to lower blood sugar levels and reduced A1C.

In conclusion, incorporating levels requires the guidance of a healthcare professional. Understanding their use, dosage, and potential side effects is crucial for safe and effective management of blood sugar levels.

6. Monitoring and Tracking Your Progress: Tips and Strategies
