People with liver disease or insulinoma, a tumor in the pancreas
Those who drink excessive amounts of alcohol
Hypoglycemia, also known as low blood sugar, is characterized by low levels of glucose, the
body’s main source of energy It occurs when the amount of insulin in the blood exceeds the amount
needed to metabolize the available glucose in the body The condition may occur when a person with
diabetes takes too much insulin, but it can also happen under other circumstances, such as
overconsumption of alcohol; taking large amounts of aspirin or acetaminophen, beta-blockers, and
some antipsychotic drugs; or when tumors develop that secrete insulin
Symptoms include confusion, abnormal behavior, double vision, heart palpitations, shakiness,
anxiety, sweating, and hunger While less common, the person may have a seizure or lose
consciousness
One condition called reactive hypoglycemia occurs when blood sugar levels plummet 1 to 2 hours
after a meal Symptoms include dizziness, headache, trembling, palpitations, and irritability This
uncommon condition can only be diagnosed by monitoring blood glucose levels after ingestion of a
known dose of glucose
Nutrition Connection
Prevent episodes of hypoglycemia with these dietary tips:
Eat small, frequent meals that are balanced An even mix of carbohydrates, fats, and proteins
will help your body metabolize the foods slowly Because they take longer than sugars to be digested
and converted into glucose, they allow for a steady release of energy
Eat foods rich in fiber Include foods that are higher in soluble fiber such as lentils, oats, barley,
apples, and citrus fruits since they are absorbed more slowly Choose whole grains (such as whole
wheat bread) over refined grains (such as white bread or pasta) as often as possible
Eat foods with a low glycemic index (GI), or load (GL) GI and GL are measurements of how
readily foods are converted to blood glucose Focus on foods that help blood sugar levels remain
stable They include apples, kidney beans, lentils, oats, barley, and bran
Avoid sweets Candies, cookies, and anything loaded with sugar can be a potential problem
Consumed by themselves, they spike up your blood glucose levels and cause the body to pump out
more insulin, which eventually leads to hypoglycemia
Avoid excessive drinking Excessive alcohol consumption can cause hypoglycemia because the
body’s breakdown of alcohol interferes with the liver’s efforts to raise blood glucose This type of
hypoglycemia can be very serious or even fatal
Address insulin reactions as soon as possible A serious type of hypoglycemia occurs when
someone with diabetes takes more insulin than is needed to metabolize the available glucose The
onset of symptoms of an insulin reaction—hunger, tingling sensations, sweating, faintness, impaired
vision, mood changes, palpitations, and a cold, clammy sensation—can be reversed by immediately
eating a tablespoonful of sugar or honey, sucking on a hard candy, or drinking a small glass (about ½
cup or 125 mL) of orange juice or a smal sugary drink
Beyond the Diet
Hypoglycemia may require medical attention A doctor can run tests to determine the cause of
hypoglycemia and then treat the condition or the underlying medical problem Sepsis, obesity, alcohol
abuse, and hormonal changes can be an underlying cause of hypoglycemia
