Glucose Spikes Explained: Lifestyle Tips for Steady Energy

Have you ever felt extremely uncomfortable after a meal? Gotten a sudden headache or dizziness taking over, followed by a crash in energy levels? Chances are your bloodstream saw a sudden spike in glucose.

While it may not last long, it is still essential to stay safe and tackle glucose spikes through better eating habits.

When food is metabolised, glucose is a byproduct that the body uses as fuel; yes, you need sugar to stay alert during team meetings. But if glucose is released too quickly in the blood, it can cause a rapid increase in blood sugar levels, called a glucose spike. This happens when insulin — the hormone that controls blood sugar — cannot keep up with the rise. While everyone experiences a sugar rush occasionally, regular spikes can lead to health problems.

Dr SZ Anwar (MBBS) explains, “A temporary spike in sugar levels after a meal is normal, but for those who can't produce insulin, this can last longer, making it harmful. We always suggest people with a history of diabetes in the family to keep an eye on the symptoms as it helps with early detection and diagnosis.” 

Glucose spikes can show up in different ways, and it's important to notice these signs to take care of your health. Common signs include:

• Fatigue: Feeling very tired after a spike.
• Irritability: Mood changes like irritability or anxiety due to changing blood sugar levels.
• Increased thirst: Feeling very thirsty because high blood sugar can cause dehydration.
• Frequent urination: Needing to pee often as your body tries to get rid of that extra glucose.
•  Headaches: Sudden shifts in blood sugar can cause headaches.
• Blurred vision: Difficulty seeing clearly.

Glucose is an essential source of energy for our cells, tissues, and organs — especially the brain. However, problems arise when blood sugar levels are not well regulated. Maintaining balanced glucose levels is critical for our bodies to function properly. Conversely, consistently high blood sugar can lead to insulin resistance, which can lead to type 2 diabetes if left unchecked.

 Long-term high glucose levels can lead to several health problems:

• Type 2 diabetes: A long-lasting condition affecting how your body processes sugar. High blood sugar over time can damage insulin-producing cells in the pancreas, leading to low insulin and poor glucose control.
• Heart problems: High blood sugar can harm blood vessels and increase inflammation, increasing the risk of heart disease and stroke. Atherosclerosis (plaque buildup in arteries) is a common issue with poorly managed blood sugar.
• Nerve damage: High glucose can damage nerves, especially in the legs and feet. This is called diabetic neuropathy and can cause numbness, tingling and severe infections if left untreated.

Blood sugar spikes can feel like a rollercoaster ride. But you can ease it by making a few changes to your eating habits. Here's how to keep your sugar levels steady and your energy stable.

Eat right to help maintain glucose levels and avoid spikes. 

• Fibre is your friend: Fibre helps slow down sugar absorption, preventing spikes. Eat whole grains, beans, lentils, fruits, and veggies for a steady energy supply. Here’s an easy routine to follow: Start your meals with fibre, like a simple salad, follow it up with protein, like dals, and end with cereals. Fibre makes a mesh in the intestine, preventing sudden glucose spikes.  
• Balance is key: Combine protein, healthy fats, and complex carbs in your meals to stay satisfied and stable. Examples include a grilled chicken salad with avocado or yoghurt with nuts and seeds.
• Portion perfection: Pay attention to your body's hunger signals when you eat. Limiting your plate size can help you avoid overindulging. Chew gradually to allow your body enough time to register fullness.

When it comes to blood sugar, timing is everything. Eating five or six smaller meals instead of three big ones can keep your sugar levels steady, giving your body a constant fuel drip and preventing those energy crashes. 

Sports nutritionist Puneet Pandey suggests, “Planning your meals, just the way you would plan your meetings or workday. Make sure you have access to nutrient dense snacks so that you are not eating after long gaps which is one of the major reasons for sudden glucose spikes.” A mid-morning snack of fruit, nuts, and seeds can also be a game-changer. It keeps hunger at bay and prevents overeating. The key is avoiding long stretches without food, which can affect your appetite and blood sugar.

Many think managing blood sugar means giving up delicious desserts, but that's not necessarily true. With smart choices and moderation, you can still enjoy your favourite sweets without compromising your health.

The key to enjoying desserts while managing blood sugar is moderation. This means having sweet treats occasionally and in smaller portions rather than indulging too often. Being mindful of your intake can satisfy your cravings without causing significant blood sugar spikes.

Choosing the suitable desserts can help manage blood sugar levels: 

• Fruit-based delights: Fresh fruits provide natural sweetness, fibre, vitamins and antioxidants. For a nutritious dessert, try fruit salads, baked apples or berry mixes.
• Dark chocolate: Dark chocolate (70% cocoa or higher) has less sugar and more antioxidants than milk chocolate. Enjoy a small piece with nuts for extra benefits. 
• Yoghurt parfait: Mix plain yoghurt with fruits and nuts for a protein-rich dessert. Greek yoghurt is a good choice due to its high protein content.

If you constantly crave sugary food, you might have magnesium deficiency. It is advisable to add magnesium-rich items like tofu, nuts and dark leafy vegetables like spinach and kale to your diet.  

What we eat plays a significant role in managing blood sugar, but don't forget about movement! Staying active isn't just about burning calories; it's a great way to keep your sugar levels in check and boost your overall health.

Exercise is excellent for your body because it makes your cells more sensitive to insulin, the hormone that helps use sugar for energy. When your cells are more sensitive, they handle sugar better, which prevents blood sugar spikes. 

Also, when you exercise, your muscles use sugar for fuel, acting like a “sugar vacuum” to lower blood sugar levels. Regular exercise can help prevent diabetes and improve insulin resistance over time.
You don't need a gym to see the benefits. Small changes can make a big difference: 

• Walking: A brisk 30-minute walk or completing a hundred steps after meals helps process sugar and avoid post-meal spikes. If this sounds too much, you can also take a 10-minute walk post your meal. In fact, Dr Means and Dr Huberman state, “30-35% (difference), just taking a walk around the block after a meal. That’s definitely a prescription I think everyone should do.”
  Sneaking movement into your everyday routine can be as simple as taking the stairs instead of the elevator for a quick boost, parking farther from your destination to get extra steps.
• Stretching: Simple stretches improve blood flow, helping your body deliver sugar to your muscles. Plus, stretching can help you relax and reduce stress, affecting blood sugar.
• Resistance training: Strength training helps your body use insulin more efficiently and build muscle, which helps burn sugar more effectively. 

A sugar or glucose spike happens when blood sugar levels rise quickly after a meal. It can cause fatigue, headaches, increased thirst and urination, blurred vision, and difficulty concentrating. These spikes are a natural response to a sudden increase in sugar intake but can be uncomfortable if persistent.

To reduce glucose spikes, choose foods with a low glycemic index that are high in fibre, protein, and healthy fats. Avoid refined carbs and added sugars. Add complex carbs (like legumes and grains) to your diet, exercise regularly and reduce stress. Doctors can prescribe medications to help you manage glucose spikes.

Foods that cause glucose spikes are usually high in refined carbs and added sugars, such as white bread, pasta, pastries, sodas, and candy. Starchy vegetables, tropical fruits, and dried fruits can also spike blood sugar. Moderation and a balanced diet can help manage these effects.

Five common signs of high blood sugar are increased thirst and urination, fatigue, blurred vision, slow healing of cuts or bruises and tingling or numbness in the hands or feet. Some people may not have symptoms, so regular testing is essential to monitor blood sugar levels.

Glucose spikes are harmful because they stress the body and can lead to insulin resistance, prediabetes and type 2 diabetes over time. Frequent spikes increase inflammation and oxidative stress, which are linked to conditions such as heart disease, nerve damage and kidney disease. Managing these spikes is crucial for overall health.

You don't need to quit sugar, as it is naturally found in many healthy foods. However, limiting added and refined sugars is essential for controlling glucose spikes and maintaining steady energy levels. Aim to get sugar from whole foods like fruits and dairy and practice moderation with your sugar intake.
