Nutrition Management of Low Blood Sugar without Diabetes
(Postprandial Syndrome and Reactive Hypoglycemia)

What is Hypoglycemia?
Hypoglycemia is a medical term for low blood sugar (glucose). Glucose is the sugar that our
bodies use for energy. In most people, a normal level of blood sugar is within a range of 70 to
99 mg/dL. Hypoglycemia can be a concern for people with diabetes, but it also affects people
who do not have diabetes. Two conditions that can affect people without diabetes are
postprandial syndrome and reactive hypoglycemia. The nutrition guidelines we recommend for
treatment are the same for both.

ξ Postprandial syndrome is when someone develops symptoms of low blood sugar within
4 hours after eating but blood sugar doesn’t actually drop below normal. Postprandial
means after eating. Having these symptoms may be related to eating a high carbohydrate

ξ Reactive hypoglycemia is symptoms of low blood sugar along with a blood sugar level
less than 70 mg/dl. This too most often occurs about 4 hours after a meal and symptoms
improve right away with intake of carbohydrates.
In postprandial syndrome or reactive hypoglycemia, symptoms may occur within 2 to 4 hours
after a meal. People have some or all of these symptoms:
ξ Hunger
ξ Sweating
ξ Shakiness
ξ Weakness
ξ Fatigue
ξ Nausea/vomiting
ξ Numbness/coldness in arms or legs
ξ Mood swings
ξ Double vision/blurred vision
ξ Fast pulse rate
ξ Headache
ξ Anxiety
ξ Craving for sweets
ξ Flushing
ξ Confusion
ξ Irritability

Diagnosis and Treatment
Hypoglycemia is diagnosed by measuring blood glucose when you are having symptoms. A
small blood sample is taken and sent to a lab. If blood glucose is below normal (less than 70
mg/dL) and the symptoms disappear when food is eaten, reactive hypoglycemia is most often the
cause of these symptoms. To manage this type of hypoglycemia you need to make changes in
your eating habits. The goal is to maintain a blood glucose between 70 to 99 mg/dL and prevent
symptoms. If blood sugar is not below 70 mg/dl this is likely postprandial syndrome (symptoms
of low blood sugar but blood sugars remain in normal range).

Eating to Prevent Hypoglycemia
 Limit foods high in sugar and concentrated sweets. Eating these foods can cause a rapid
increase in blood glucose. This may lead to excessive increase of insulin, resulting in a rapid
fall in blood glucose.

Foods high in sugar include:
ξ Cakes ξ Jelly and Jams
ξ Cookies ξ Candy and Candy bars
ξ Pies ξ Gelatin, Jello™
ξ Puddings and Custards ξ Nectars (Agave)
ξ Regular Soda ξ Honey
ξ Lemonade, Kool-Aid™, Punch
ξ Sugar, Brown sugar
ξ Ice cream, Sherbet, Frozen Yogurt
ξ Syrups (Corn, Pancake, Maple)
ξ Fruit juice greater than 4 ounces
ξ Sweet Tea and Flavored Coffee

 If you have something sweet try to have it with a meal. You can handle sweet foods better
if eaten with a meal since the other foods at the meal reduce the effects of the sugar.

 Reduce intake of foods and drinks that have caffeine. Caffeine stimulates the production
of adrenaline and can cause the same symptoms as hypoglycemia.

 Limit or avoid alcoholic drinks. Drinking alcohol can cause hypoglycemia all by itself,
especially on an empty stomach. If you choose to drink alcohol, do so in small amounts and
always consume it with food. One serving of alcohol is 12 oz. beer, 4 oz. wine and 1.5 oz

 Spread your intake of carbohydrate foods throughout the day. Eating large amounts of
rice, bread, cereal, pasta at one time can cause your body to produce large amounts of insulin.
This is much like simple sugars or sweets and can cause glucose levels to drop sharply.

 Try to eat every 3 to 4 hours. Eating many small meals and snacks each day rather than 3
larger meals can help to regulate the amount of glucose in your bloodstream.

 Aim for 2 to 4 servings of carbohydrate at each meal (30 to 60 grams) and 1 to 2
servings (15 to 30 grams) at snack times. One carbohydrate serving has 15 grams of total

Each of these foods contains about 15 grams of carbohydrate:
ξ 1 regular slice of bread ξ 6 saltines
ξ ½ English muffin, hot dog or hamburger bun ξ 3 cups popcorn
ξ ½ cup rice, pasta, cooked cereal ξ ½ 3-inch bagel
ξ 1 medium potato (about ½ cup) ξ 1 (6”) flour tortilla
ξ 1 small apple (tennis ball size) ξ 1 medium orange
ξ ½ cup fruit canned in its own juice ξ ¾ cup grapes
ξ ¾ cup high fiber cold cereal
ξ 1 cup plain, light or Greek yogurt
ξ 1 cup cantaloupe
ξ 1 cup skim or 1% milk

 Choose whole grains and increase high fiber foods. Whole grains take longer to break
down. This helps to keep blood glucose levels more consistent. Whole grain breads and
cereals, legumes/beans, vegetables and whole fruits are high in fiber. These foods will help
you eat at least 25 grams of fiber daily.

 Include lean protein at each meal and snack. Our body breaks down protein more slowly
than carbohydrate. This mixture of carbohydrate and protein can give a long-lasting source of
energy. Good sources of lean protein foods include skinless poultry, fish, low-fat cheese,
eggs, peanut butter, and soy-based foods.

 Enjoy foods high in healthy fats in small amounts throughout the day. Fats are also
digested slowly and can help to balance the blood sugar. Choose healthy fats such as nuts,
seeds, avocado, olives and olive oil. Try to enjoy fats in small amounts because they are also
high in calories and can lead to weight gain.

 Keep some non-perishable foods on hand to prevent or treat low blood sugar
symptoms. Granola bars with protein, or nuts and dried fruit mix are examples of quick,
healthy snacks. Keeping these foods on hand is a good choice instead of getting a high
calorie candy bar from the vending machine or store.
