what to do when blood sugar is high?
Managing elevated blood sugar levels can be overwhelming, especially if you’re dealing with complications like diabetic nephropathy with proteinuria. High blood sugar, or hyperglycemia, can be a serious concern if not managed properly. Whether you’re newly diagnosed or managing diabetes for years, understanding what to do when blood sugar is high is vital to prevent complications and live a healthier life.
What is High Blood Sugar
Blood sugar, also known as glucose, is the body’s primary energy source. However, when glucose levels rise too high, it can lead to hyperglycemia, a condition that may cause symptoms such as frequent urination, excessive thirst, fatigue, and blurred vision. If left untreated, it can result in long-term complications like heart disease, nerve damage, and even diabetic ketoacidosis (a life-threatening condition).
Knowing how to act quickly and effectively is key to avoiding severe health issues.
Causes of High Blood Sugar
Before we jump into how to lower your blood sugar, it’s crucial to understand some common triggers of hyperglycemia:
- Carbohydrate-rich meals: Eating large quantities of carbs can cause a spike in glucose levels.
- Skipping or reducing medication: Forgetting to take insulin or oral diabetes medication can result in elevated blood sugar.
- Inactivity: Exercise helps regulate blood sugar, so lack of physical activity can cause levels to rise.
- Illness or stress: Physical or emotional stress can increase the release of hormones that affect glucose levels.
- Hormonal changes: Certain life stages, like pregnancy, can affect insulin sensitivity, causing blood sugar fluctuations.

What to Do When Blood Sugar is High
When blood sugar levels rise above the target range, quick actions are necessary to bring it back down. Here’s what you should do when blood sugar is high:
1. Check Your Blood Sugar Levels
The first step in managing high blood sugar is to monitor it. Regularly checking your glucose levels helps you understand when it’s necessary to take action. If your blood sugar is higher than the recommended range (usually above 180 mg/dL), it’s time to act. You can also use a continuous glucose monitor (CGM) for real-time monitoring.
2. Take Insulin or Medication
For those on insulin therapy, administering a rapid-acting insulin dose can help lower blood sugar quickly. Follow your healthcare provider’s instructions carefully on how much to take. Never make changes to your medication regimen without consulting a doctor, as improper use can lead to dangerously low blood sugar (hypoglycemia).
If you’re on oral medication, taking it as prescribed is crucial. If you’ve missed a dose, consult with your doctor about how to correct it.
3. Drink Water
Staying hydrated helps your kidneys flush excess sugar from the blood through urine. Drink plenty of water to support this process, but avoid sugary drinks, which will only make your blood sugar rise higher. Aim for at least 8-10 glasses of water throughout the day, especially if your blood sugar is elevated.
4. Go for a Walk or Engage in Light Physical Activity
Physical activity is one of the most effective ways to lower blood sugar levels. A brisk walk, light jogging, or any form of moderate exercise helps your muscles use glucose more effectively. However, avoid intense workouts when your blood sugar is extremely high (over 300 mg/dL), as it can make things worse, particularly if ketones are present in the urine.
5. Eat Mindfully
What you eat plays a significant role in managing your blood sugar levels. Choose foods with a low glycemic index (GI), as they cause a slower, more gradual rise in blood sugar. Some excellent options include:
- Whole grains like oats, quinoa, and brown rice
- Leafy greens and non-starchy vegetables
- Protein-rich foods such as chicken, turkey, and fish
- Healthy fats like avocado and nuts
It’s also helpful to eat smaller, more frequent meals to avoid large glucose spikes. Consider speaking to a nutritionist to create a personalized meal plan.
6. Relax and Manage Stress
Stress can lead to hormonal changes that elevate blood sugar levels. Engage in stress-relieving activities like meditation, deep breathing exercises, or even a short walk outdoors to calm your mind and body. Managing your emotional well-being is as essential as managing your physical health when it comes to controlling blood sugar.
Seek Medical Help
Sometimes, despite your best efforts, your blood sugar may remain high. If you experience any of the following symptoms, it’s time to call your healthcare provider:
- Persistent high blood sugar readings (above 240 mg/dL) despite taking insulin or medication
- Symptoms of diabetic ketoacidosis, including fruity-smelling breath, confusion, shortness of breath, or extreme fatigue
- Repeated high blood sugar readings after meals or during fasting periods
These could be signs of more severe issues that require immediate medical attention. It’s always better to be proactive about your health rather than wait for complications to arise.
How to Prevent High Blood Sugar
Preventing high blood sugar is crucial for managing diabetes and maintaining overall health. Here are some effective strategies to help keep your blood sugar levels stable:
- Follow a Balanced Diet
Focus on eating a variety of whole grains, lean proteins, healthy fats, and fiber-rich vegetables. Avoid sugary and processed foods, as they can cause blood sugar spikes. - Monitor Carbohydrate Intake
Carbs have the most significant impact on blood sugar. Learn to track and control the amount of carbohydrates you eat, opting for low glycemic index (GI) foods. - Stay Physically Active
Regular exercise helps improve insulin sensitivity and lower blood sugar levels. Aim for at least 30 minutes of moderate activity, like walking or cycling, most days of the week. - Stay Hydrated
Drinking plenty of water helps your kidneys flush out excess sugar through urine and keeps you hydrated. - Take Medication as Prescribed
If you’re on medication or insulin, ensure you follow your healthcare provider’s instructions. Missing doses can lead to uncontrolled blood sugar. - Manage Stress
Stress can cause blood sugar levels to rise, so practice relaxation techniques like deep breathing, meditation, or yoga to keep stress under control. - Get Enough Sleep
Poor sleep can affect how your body processes insulin, leading to higher blood sugar. Aim for 7-9 hours of restful sleep each night.
By incorporating these habits into your daily routine, you can help prevent high blood sugar and keep your diabetes well-managed.
When blood sugar is high, drink water to flush out excess glucose and engage in light exercise, like walking, to lower levels naturally. Monitor your blood sugar closely and adjust medication or insulin as prescribed. Avoid sugary and high-carb foods, opting for fiber-rich alternatives. If levels stay elevated, consult your healthcare provider. Managing stress and sleep can also aid in blood sugar control.
