Hypoglycemia (Low Blood Sugar)
What is Hypoglycemia or low blood
sugar?
When blood sugar falls
below 70 mg/dL you may have hypoglycemia (low blood sugar). When
this happens, most people experience unpleasant symptoms that can be
both physical and emotional and if it not dealt with quickly,
serious reactions may result, including passing out or having
convulsions. Because these symptoms can come on quite suddenly it is
highly desirable to learn how to avoid hypoglycemia.
Symptoms
of Hypoglycemia (low blood sugar)
When
blood sugar gets too low you may:
-
feel shaky
-
be sweaty
-
feel tired
-
be hungry
-
have a fast heartbeat
-
become crabby or confused
-
have blurred vision or a headache
-
have no symptoms at all
Having
no symptoms at all is a dangerous situation! First treat the low blood sugar level, then call your doctor if you
ever had a blood sugar reading below 60 mg/dL, without
experiencing symptoms. A blood sugar level this low needs
treatment, even if you’re feeling fine.
Low
blood sugar feels different to different people. Learn to recognize your own particular symptoms.
What causes
hypoglycemia? The most common causes of
hypoglycemia are:
-
skipping or not finishing meals or snacks
-
taking too much diabetes medication
-
eating foods that do not provide a sustained supply of
glucose
-
eating at the wrong time for the medicine you take
-
getting more exercise than usual
-
getting stressed
-
drinking alcoholic beverages
Skipping or delaying meals can cause low blood sugar in
people who take sulfonylurea, meglintide or insulin. These drugs increase the
body’s insulin level. Unless insulin in the blood is balanced by food, it can
cause your blood sugar level to fall too low.
