Blood Sugar High One Hour After Eating – What To Do

Daily consumption of sugar can lead to an unhealthy accumulation of sugar in the blood, causing your blood sugar levels to rise.

The blood sugar level is how much sugar is present in the blood. For example, an average person weighing about 165 pounds has about one-third of gallons of blood in their body.

Hyperglycemia (High blood sugar level), if left untreated, can lead to chronic health conditions.

Keeping track of your blood sugar before after meals is one of the first steps to keep your blood sugar level under control.

Can I Check Blood Sugar One Hour After Eating?

According to the American Diabetes Association (ADA), one of the measures to manage your blood sugar spike after a meal requires checking your blood sugar levels before each meal and one to two hours after.

Suppose you are particular about maintaining a healthy blood sugar level. In that case, you should know that it is essential that you keep track of blood sugar.

One of the fastest ways is to check before mealtime and one to two hours after.

Doing this constantly for about a week or more will help you keep track of notable changes, as well as the foods responsible for a spike in your blood sugar.

Some symptoms that you can experience due to an increase in your blood sugar level include a foggy feeling, reduced energy level, nervousness, or moodiness.

In addition, an extremely high blood sugar level can put you at risk of damages to organs, nerves, blood vessels.

It is also a risk factor for kidney disease and cardiovascular diseases like stroke.

How Long After Eating Does Blood Sugar Level Spike?

The blood sugar spike sometimes varies from person to person.

Typically, blood sugar level rises about an hour and fifteen minutes after eating. Postprandial spike is another term for an increase in blood sugar level.

It is an ordinary condition that occurs after eating, even in persons who do not have diabetes. However, an abnormality is an unusual or excessive spike in blood sugar.

The average blood sugar level for people who do not have diabetes is 80-100 mg/dl.
However, postprandial spikes can raise this to 160mg/dl or more.

This increase can occur within one to two hours, especially after consuming sugar-dense foods.

Below is the average blood sugar level range for people without diabetes, according to the American Diabetes Association:

  • In the morning before eating: Under 100mg/dl
  • An hour after a meal: 90-130 mg/dl
  • Two hours after a meal: 90-110 mg/dl
  • Five or more hours after a meal: 70-90 mg/dl

Is Blood Sugar Higher One or Two Hours After Eating?

Blood sugar level rises almost immediately after eating a meal or a snack.

In a healthy person, insulin starts to perform its function after this spike, causing the blood sugar to return to normal after two hours of a meal.

However, suppose your blood sugar fails to return to normal after more than two hours of a meal. It might indicate a more serious health condition.

This condition is often common in individuals who are diabetic.

Untreated patients with diabetes would still have hyperglycemia (high blood sugar level) even after two hours of the meal.

This results from your bodies’ inability to utilize insulin to regulate glucose in the bloodstream.

As a result, blood sugar levels may rise immediately after eating in a person without diabetes, especially after eating foods that contain a high amount of sugar.

However, the increase should regulate in about two hours after meals.

Is 160mg/dl Blood Sugar High After Eating?

According to standard recommendations from the World Health Organization (WHO), blood glucose levels should be between 70 to 100mg/dl.

A blood glucose rise to about 160 mg/dl or more may require changes in lifestyle, dietary habits, and immediate health care interventions.

A postprandial spike causing blood sugar levels to rise to about 160 mg/dl could indicate a high risk of diabetes.

Blood sugar levels that are higher than usual are entirely unhealthy. Levels higher than average and within 140-160 mg/dl are prediabetic.

Prediabetes is a medical condition in which blood sugar levels constantly rise more elevated than usual but not high enough to be diagnosed as diabetic.

According to the Centers for Disease Control and Prevention, research shows that approximately 88 million American adults have been diagnosed with prediabetes.

Prediabetes puts you at risk of developing type 2 diabetes, stroke, and heart diseases.

An indication of prediabetes is a sudden spike in blood sugar level after eating.

Effective measures to manage your blood sugar level include watching what you eat and taking appropriate medicines prescribed by the health care practitioner.

Is 140mg/dl Blood Sugar High After Eating?

Blood sugar level varies depending on the timeframe after eating. After two or more hours, your blood sugar level should return below 100 mg/dl. Your blood sugar should not rise above 140mg/dl hours after eating.

An increase in blood sugar level to 140 mg/dl indicates a prediabetic condition that may require immediate medical intervention.

Run simple blood tests to check if you are prediabetic, particularly if you notice a recurring spike in your blood sugar level.
In addition, your physician can recommend lifestyle and dietary changes to manage your prediabetes.

Is 200mg/dl Blood Sugar Regular After Eating?

A blood sugar level of 200 immediately after eating or hours after suggests existing cases of diabetes.

When you have diabetes, your blood sugar level may be constantly high, rising to about 200 mg/dl or more.

Over time, such an increase can lead to severe damage to tissues, blood vessels, and organs in the body.

Immediate diagnosis should follow a high blood sugar level in the affected person. The following tests will help you determine if you’re diabetic:

  • Fasting plasma glucose test
  • Oral glucose tolerance test
  • Random check

What Is A Normal Blood Sugar Level Immediately After Eating?

The average blood sugar level is less than 100 mg/dl in the fasting state(when you haven’t eaten).

It can increase to about 140 mg/dl after eating but usually reduces about 2 hours after each meal.

During the day, blood sugar levels for non-diabetic patients tend to be at the lowest, especially before meals.

It hovers around 70-80 mg/dl in some people, while it’s usually around 60 mg/dl in others. Then, after each meal, blood sugar level goes from that range to about 140 mg/dl.

Common ways to maintain a normal blood sugar level include:

  • Keeping track of your carbs consumption
  • Eat healthy foods
  • Reduce sugar intake
  • Keep a healthy weight
  • Eat more fiber
  • Exercise more
  • Weight loss programs
  • Lifestyle changes

Keep your blood sugar level in check by recognizing the meals responsible for your spike to avoid complications.

The American Diabetes Association’s goals for blood sugar control in people with diabetes are 70 to 130 mg/dL before meals and less than 180 mg/dL after meals. Reach out to your physician on keeping a healthy blood sugar level.
