Tests taken too early or too late can give an inaccurate picture of what is happening in the body. People without diabetes typically have their blood sugar levels return to close to normal about 1 to 2 hours after eating, due to the effects of insulin. This is because insulin is immediately supplied to the circulatory system while they eat, preventing a large spike in blood sugar levels. However, when consuming excess carbohydrates, the body digests them like sugar and sends them directly to the bloodstream, increasing the risk of blood sugar spikes.The rate at which food leaves the stomach, known as gastric emptying, affects the amount of sugar in the blood after eating.
Foods with a low glycemic index help ensure that the peak is not too large. In one case study, a man with diabetes was able to normalize his blood sugar levels in just 21 days by following a healthy diet and exercising regularly.Dietary changes are an important part of managing diabetes. Limiting certain types of foods that can cause high blood sugar can help keep blood sugar levels in check. Weight loss can also be beneficial for those with diabetes, as it makes it easier to stabilize blood sugar more effectively.
Postprandial blood sugar (the amount of sugar in the blood after eating) should also be monitored closely.Choosing foods that your body breaks down more slowly than refined carbohydrates can help maintain consistent blood sugar levels and provide energy. It's important to note that diabetes complications are due to long-term poor blood sugar control, not occasional short-term increases in blood sugar levels.If you're concerned about your blood sugar levels, ask your doctor for a prescription for a blood glucose meter that allows you to check your own blood sugar levels at home. Talk to your doctor about what to do in response to high blood sugar levels before changing your drug plan.
