Why is it dangerous to increase blood sugar after eating?
Doctors warn that a spike in blood sugar after meals, also known as a spike after eating, is an independent risk factor for cardiovascular disease. This is a period when blood sugar rises rapidly and then drops, creating oxidative stress and inflammation, causing damage to blood vessel walls.
A study published in the journal Diabetes Care showed that glucose after eating is more likely to increase cardiovascular risk than the HbA1c index, which measures blood sugar levels by an average of three months.
Dr. Aashish Aggarwal, a cardiologist at Fortis Hospital (India), commented on Health Shots: A spike in blood sugar after eating can be much more dangerous than a slightly high but stable blood sugar condition. This is a factor that is often overlooked in diabetes management".
According to the American Diabetes Association (ADA), blood sugar should be below 180 mg/dL after one to two hours of eating. For women with gestational diabetes, this threshold is more strict: below 140 mg/dL after one hour and 120 mg/dL after two hours.
Three strategies to reduce cardiovascular risk
To limit spikes in blood sugar, patients need to combine diet adjustment with reasonable exercise. Experts recommend:
Prioritize fiber: Non-starchy greens, beans, and whole grains help slow down the absorption of sugar.
Combine smart carbohydrates: Do not eat single starches. Combine it with protein and healthy fats, such as butter or nuts, to slow down the increase in blood glucose.
Do light exercise after meals: Just walking for 10 - 15 minutes also helps muscles absorb excess glucose, avoiding prolonged high blood sugar.
Controlling post-meal blood sugar is one of the most proactive steps to protect long-term heart health, Dr. Aggarwal emphasizes. Recording a meal and monitoring your blood sugar will help you identify the foods that have the biggest impact."
In addition, the US Centers for Disease Control and Prevention (CDC) also recommends that patients monitor themselves after meals to better understand their bodies. In fact, even seemingly healthy foods like oats can cause blood sugar to spike in some people.
Proactively monitor and protect health
Checking your blood sugar after eating regularly is the only way to know if you have achieved your control goals. When determining "active" foods, patients can adjust the menu accordingly.
It is important to maintain a balanced lifestyle: eat a lot of fiber, limit refined carbohydrates, combine protein, exercise gently and get enough sleep. These small but persistent steps will help reduce the risk of cardiovascular complications and improve the quality of life.
