Glucose spikes: what they are and what their symptoms are in the body

Do you feel hungry again shortly after eating or notice drops in energy during the day?Diet, stress and your pace of life directly influence blood glucose levels. When these levels do not stay stable, what are known as sugar spikes or glucose spikes appear. In today’s post, we explain what they are, their symptoms and how they can be controlled or prevented.

What are glucose spikes?

Blood glucose spikes are defined as a rise in blood sugar levels, which usually happens after eating, especially if a large amount of carbohydrates or sugars is consumed, although they can also occur for other reasons such as physical or mental stress, dehydration or the use of some medicines, among other factors.

Although it is normal for glucose levels to vary throughout the day, sugar spikes are a particular issue because they occur when there is more glucose in the blood than the body can absorb and use as a source of energy, putting health at risk, especially in people with conditions such as diabetes. A sugar spike is generally considered from levels of 140 mg/dl in the blood.

Symptoms of glucose spikes

The symptoms of glucose spikes can vary, but generally include tiredness, thirst and hunger. Although most people experience these symptoms, there are also asymptomatic cases. The reason hunger appears is that blood glucose spikes after eating are often followed by a later drop or decrease in blood sugar, which leads to the need to eat again shortly after a meal. This last symptom is one that deserves attention, because it often creates a cycle of spikes and drops in blood sugar.

In some cases, the following may also appear:

  • Headache
  • Blurred vision
  • Difficulty concentrating
  • Irritability
  • A frequent need to urinate

In the long term, this can affect overall health by damaging blood vessels and cells, potentially leading to cardiovascular and kidney disease.

How to avoid glucose spikes

Below, we explain some guidelines to help you understand how to control glucose spikes or how to lower glucose spikes.

  • Diet is a key factor in managing these blood sugar levels, as it is the most influential factor, so making changes to your diet can help prevent glucose spikes.
  • This is where the glycaemic index comes into play. It is a parameter used to measure how quickly a food can raise blood glucose levels, which means there are foods with a low, medium or high glycaemic index. Factors such as fibre or fat content, whether foods are liquid or solid, and their temperature and cooking process all influence this parameter. In this sense, it is better to choose foods with a low glycaemic index, which release glucose into the blood steadily, and to avoid those with a high glycaemic index. Some examples are: - High: white bread, wheat flour, boiled potato, white rice, honey, cooked carrot, refined sugar...- Low-medium: green vegetables, most fruits such as banana, pineapple and cherries, beans, chickpeas, lentils, maize, oat cereals and wholemeal or rye bread.On the other hand, it is recommended to avoid foods that trigger sugar spikes, such as those with a high amount of refined sugar in their composition, fizzy drinks or desserts, as these are another of the main causes of disproportionate rises in blood sugar.

  • Another factor to consider is exercise. Regular exercise improves the way the body uses insulin and helps control blood sugar levels.
  • Certain food supplements may help improve insulin sensitivity and stabilise sugar levels.

Aboca Metarecod

Aboca Metarecod is a natural formula in sachet format that, thanks to the combination of all the ingredients in its formula, works by modifying the characteristics of the intestinal contents, specifically the absorption of fats and carbohydrates. It makes the speed of absorption more gradual while also reducing the total amount absorbed and helping with elimination. It also reduces the reabsorption of bile acids, helping to rebalance cholesterol levels and, thanks to its viscosity, also helps protect the intestinal mucosa.

For all these reasons, it helps rebalance altered metabolic parameters, supporting the normalisation of blood sugar, cholesterol and triglycerides, while also helping reduce abdominal circumference. This makes it very useful for managing metabolic syndrome, as long as taking it is accompanied by a healthy lifestyle that includes a balanced diet and regular physical activity.

The recommendation for the duration of the treatment is 3 months, and it is possible to repeat the treatment cycle several times during the year.
