This occurs in Prediabetes:

Reactive Hypoglycemia

Reactive hypoglycemia is the general term for having a hypo after eating, which is when blood glucose levels become low following a meal.

Also known as postprandial hypoglycemia, drops in blood sugar are usuaLLY occur within four hours after eating.

Reactive hypoglycemia can occur in both people WITH, and is thought to be more common in overweight individuals or those who have had gastric bypass surgery

What are the causes of reactive hypoglycemia?

Scientists believe reactive hypoglycemia to be the result of too much insulin being produced and released by the pancreas following a large carbohydrate-based meal.

This excess insulin production and secretion continues after the glucose derived from the meal has been digested, causing the amount of glucose in the bloodstream to fall to a lower-than-normal level.

What causes this increase in pancreatic activity is unclear.

One possible explanation is that in rare cases, a benign (non-cancerous) tumour in the pancreas may cause an overproduction of insulin, or too much glucose may be used up by the tumour

Signs and symptoms of reactive hypoglycemia

Symptoms of reactive hypoglycemia can include:

Anxiety
Blurred vision
Confusion
Dizzy spells
Fatigue
Headaches
Heart palpitations
Increased hunger
Irritability
Light-headedness
Sleeping problems
Sweating
Weakness

When talking about the signs of reactive hypoglycemia, it’s important to note that many of the symptomsbe falling blood sugar levels after eating, and the with the actual cause for many people often relating to what food was eaten or variations in the timing of the food moving through the stomach and intestinal tract

If there is no hypoglycemia at the time of the symptoms, you may have what is known as “postprandial syndrome”.

Sometimes it could be related to anxiety

Diagnosis

This could be made by checking the blood sugar at the time of symptoms. In general the blood sugar is less than 70 mg per dl or there could be rapid fluctuations in the blood sugar. This can be diagnosed by measuring the blood sugar every 5 minutes which is called continous glucose monitor

Treatment

No medical treatment is usually required for cases of reactive hypoglycemia. Instead, patients are generally advised to:

Reduce carbohydrate intake and/or eat frequent small meals – the first step of treatment is to split your daily diet into several small meals and snacks, no more than 3 hours apart., which are less carb-heavy.
Eat a well-balanced diet, including meat, poultry, fish, nonmeat sources of protein, dairy products and fibre-rich foods such as whole grains, fruit and vegetables.
Avoid or limit sugary foods and drinks, especially soft drinks rich in glucose or sucrose.
Exercise regularly – physical activity increases sugar uptake which, in turn, decreases excessive insulin release.
Eat food when drinking alcohol and avoid using sugary soft drinks as mixers.

with the continous glucose monitor we could change the diet exercise and make objective changes in the blood sugars
