Postprandial Glucose: What is it? Signs, Symptoms and Treatment

People who do not have diabetes are able to produce insulin naturally. On the other hand, people with type 2 diabetes can not make enough insulin.

It is a condition in which a person has extremely high blood glucose levels after eating.

Usually, blood glucose levels increase slightly after eating food. Glucose is a form of sugar that is one of the main sources of energy for the body. We obtain glucose from foods rich in carbohydrates, such as rice, bread, milk and potatoes.

When we eat these foods, our body breaks them down into glucose that is then transported to various body tissues through the bloodstream.

However, for glucose to enter the cells of the body and be used as energy, it requires insulin. Insulin is a natural hormone produced by the beta cells of the pancreas.

This natural hormone is responsible for transporting glucose to body tissues, such as fat and muscle cells. Because of this, they may experience postprandial hyperglycemia (after the meal).

It is considered to have postprandial hyperglycemia when your blood glucose levels exceed 180 mg / dL. For non-diabetics, blood glucose levels rarely go beyond 140 mg / dL after eating.

However, if you eat a large meal that contains a large amount of carbohydrates, your postprandial glucose levels can reach up to 180 mg / DL.

Postprandial hyperglycemia is a challenge for people with diabetes who aspire to achieve a stable level of blood sugar. High blood glucose levels can cause serious health complications, including damage to the nerves, kidneys and blood vessels.

People with diabetes can receive insulin injections to help them stabilize their blood glucose levels.

Signs and symptoms

Several factors can contribute to the symptoms of food. It is likely that people who experience physiological stress experience postprandial hyperglycemia. This is because when your body is under stress, it releases several hormones, which can increase your blood glucose levels.

Certain types of medications such as epinephrine , corticosteroids, and niacin may contribute to the risk of food.

Diabetes mellitus is one of the main causes of food. This is because patients with diabetes mellitus do not produce enough insulin to absorb and process sugar (glucose) in the blood.

When your blood sugar level is high, you may feel a cloudy head, which can make concentrating and concentrating difficult.

You can also get cranky or feel nervous. If you experience any of these symptoms, it is important that you seek medical attention immediately. If left untreated, high blood sugar can cause health complications, such as heart disease and stroke.

The following are signs and symptoms of postprandial hyperglycemia:

  • Blurry vision.
  • Fatigue.
  • Weightloss.
  • Drowsiness.
  • Increased thirst.
  • Dry mouth.
  • Frequent urination


The main objective of the treatment of postprandial hyperglycemia is to bring blood glucose to levels as high as possible in three components of glycemic control, ie the peak of glucose after meals, HbA1 and fasting glucose.

So you can effectively treat after the meal, you must work to prevent it. If you are using insulin medications, your doctor may need to adjust your dose to avoid the risk of postprandial hyperglycemia in the future.

If you are diabetic or not, it is recommended that you exercise regularly so that you can maintain a healthy blood glucose level.

Your doctor can advise you to adopt a healthy diet plan to avoid the risk of a meal after a meal.

Your diet plan may include reducing your alcohol consumption, carbohydrate intake and the inclusion of whole grains, fruits and vegetables in your diet. Because postprandial hyperglycemia occurs after meals, it is important that you consume the correct types and amounts of carbohydrates.

In case you have problems with your meal plans, you can check with your dietitian about the best diet plan that works for you. Managing your stress levels can also help you prevent food.

Drugs for postprandial hyperglycemia

For patients who have type 2 diabetes, there are several medications designed for postprandial hyperglycemia.

Short-acting insulins are preferable to long-acting insulin because of their ability to start work in a short period of time. You can take insulin regularly for at least half an hour to one hour before meals so that the glucose rise and insulin peak match.

You can also choose to use rapid-acting insulin such as insulin lispro, insulin aspart or insulin glulisine 15 minutes before eating. In addition to insulin, type 2 diabetic patients can use oral medications to help control them after meals.

For example, miglitol and acarbose block enzymes in the small intestine that break down carbohydrates into sugar. Therefore, sugar slowly enters the blood, which gives insulin enough time to control it.

The drugs nateglinide and repaglinide work by stimulating the pancreas to secrete insulin based on the amount of glucose available in the blood. Therefore, in case there is too much glucose in the bloodstream, more insulin will be released. Therefore, they are able to control the food.
