What is a Normal Blood Sugar Level Immediately After Eating?

According to the World Health Organisation(WHO), normal blood sugar levels in the fasting state for non-diabetics should be between 70 mg/dL and 100 mg/dL. However, normal blood sugar levels after eating (immediately) are greater because of the food intake. The level of sugar after meal rises as food gets converted into sugar or glucose. Therefore, your after breakfast blood sugar level, post lunch blood sugar levels and after dinner sugar levels will be much higher than your fasting sugar levels. So, in the chart below, we have summarised normal blood sugar levels after eating (immediately):

Group Fasting Blood Sugar Levels Normal Blood Sugar Levels After Eating (Immediately)
Non-diabetics 70-100 mg/dL 170-200 mg/dL
Pre diabetics 100-125 mg/dL 190-230 mg/dL
Diabetics Above 125 mg/dL 230-300 mg/dL

How Does Food Affect Blood Sugar After Meal?

How Does Food Affect Blood Sugar After Meal?

The body breaks the food you eat into carbs, proteins, fats, vitamins, minerals, etc. Carbs are the nutrients that affect the blood sugar levels the most. Therefore, overconsumption of carbs can lead to blood sugar spikes. But you should also know not all carbs convert into blood sugar at the same rate. Carbs are divided into three broad categories which you derive from food.

  • Simple Carbs or sugar: You get this from foods like fruits, refined products, bakery products, juices, desserts, mithais, processed foods, etc.
  • Complex carbs or starches: You get this through starchy veggies, rolled oats, millets like chickpeas, barley, etc.
  • Fiber or non-digestible carbs: You obtain this from non-starchy or green veggies, and low-GI fruits like apples, avocados, beans, and whole grains.

Simple carbs are the quickest to break down. They convert into glucose and cause maximum blood sugar spikes. Complex carbs slowly break down and are less likely to cause blood sugar fluctuations or spikes. Complex carbs contain fiber, which slows down their digestion. The glycemic index measures the rise in blood sugar in the food. This index ranks food between 0 to 100 and classifies them as low, medium and high. Foods that score lower or have low glycemic scores cause less or no spike. These foods are good for you since they are processed slowly. On the contrary, foods scoring higher cause maximum spikes and should be avoided.

Why Measuring Blood Sugar After Eating Food is Important?

Blood glucose is the prime or main source from which your body gets its energy. In the process of digestion, carbs like sugar, starch and fiber all get converted to glucose. Therefore, eating an unregulated amount of carbs can spike your blood sugar to unhealthy levels. This situation, especially for diabetes patients, is not at all desired.

For diabetes patients it’s necessary to maintain normal blood sugar after meals and before meals. Keeping normal blood sugar levels after eating and overall prevents hyperglycemia (high blood sugar). If a diabetes patient doesn’t keep a check on the blood sugar levels and stays in hyperglycemia, it can inflict severe damage to body cells and organs. It can cause diabetes-related complications like diabetic retinopathy (eye-related damage), diabetic nephropathy (kidney ailments, diabetic nephropathy (nervous system damage), heart attacks, etc.

Therefore, diabetic patients should try to maintain normal sugar level after and before food. They should get their blood sugar regularly checked and follow necessary dietary guidelines. Your diabetologist may want to know your blood sugar at different hours of the day, which can be done through CGM machines at home. Or they will ask you to measure the sugar level before and after meals (after 2 hours).

Who Needs to Check Average Blood Sugar After a Meal?

For diabetes patients, whether type 1 or type 2, they must measure blood sugar at regular intervals. Measurement of blood sugar helps them and the doctor to prescribe the medication and its dosage. Additionally, blood sugar reading plays a part in deciding the food choices and physical workout intensity.

Checking blood sugar is also necessary for pregnant women who have or are at risk of gestational diabetes. If you have a tendency to hypoglycemia (low blood sugar), which can be due to medicines or present health conditions, you need to measure your blood sugar.
