Hypoglycemia is a low blood sugar level. This condition is sometimes called an insulin reaction because hypoglycemia is nearly always a side effect of diabetes drug therapy. Recognizing hypoglycemia is important so that action can be taken quickly to restore the blood sugar to a normal level. Severe hypoglycemia can lead to potentially life-threatening seizures, accidents or injuries. Notably, diabetic children and adults with long-standing diabetes may be unable to recognize when their blood sugar is low. Therefore, it is important that those around them know the signs of hypoglycemia.
Shakiness
Low blood sugar typically causes shakiness, which is easily recognized in the hands. The shakiness can make it difficult to pick up small objects, or you may notice items being dropped.
Clumsiness
Inadequate blood sugar often causes clumsiness. An unsteady walk, running into things, tripping and exaggerated or jerky movements are common and may be confused with drunkenness.
Slurred Speech
Severe hypoglycemia can cause slurred speech. This, too, may cause an observer to mistakenly assume the person suffering from low blood sugar is intoxicated.
Sweating and Paleness
One of the body's responses to low blood sugar is a release of adrenalin (the "fight or flight" hormone). The sudden rush of adrenalin causes sweating, which may be accompanied by paleness or an ashen skin tone.
Weakness
Without sufficient glucose (blood sugar), the muscles lack adequate fuel to work at full power. Therefore, an episode of hypoglycemia may bring on observable weakness.
Nervousness and Agitation
Nervousness and agitation are common when the blood sugar is too low. This may manifest as jitteriness, inappropriate irritability or a short temper.
Moodiness
A person experiencing an insulin reaction may exhibit abrupt changes in mood that seem inappropriate to the circumstances. Laughing, crying or becoming angry without apparent cause are common.
Inattention
Low blood sugar profoundly affects the brain. During an episode of hypoglycemia, a person may seem unable to focus or pay attention, or may appear easily distracted.
Confusion
A person with low blood sugar is often confused. She may not realize exactly where she is or why. This sign of hypoglycemia is often mistaken for drunkenness.
Sleepiness
Hypoglycemia may cause sleepiness. Be alert for a sudden onset of sleepiness that seems out of place. Also keep in mind that hypoglycemia can occur during the night. A person who has become hypoglycemic during the night may be difficult to awaken in the morning, or he may have trouble staying awake.
