Hypoglycemia known as low blood sugar, is a fall in blood sugar to levels below normal. This may result in a variety of symptoms including clumsiness, trouble talking, loss of consciousness, seizures or death. A feeling of hunger, sweating and weakness may be present. Symptoms come on quickly; the most common cause of hypoglycemia is medications used to treat diabetes mellitus such as insulin and sulfonylureas. Risk is greater in diabetics who have eaten less than usual, exercised more than usual or drunk alcohol. Other causes of hypoglycemia include kidney failure, certain tumors, liver disease, starvation, inborn error of metabolism, severe infections, reactive hypoglycemia and a number of drugs including alcohol. Low blood sugar may occur in otherwise healthy babies; the glucose level that defines hypoglycemia is variable. In people with diabetes, levels below 3.9 mmol/L are diagnostic. In adults without diabetes, symptoms related to low blood sugar, low blood sugar at the time of symptoms and improvement when blood sugar is restored to normal confirm the diagnosis.

Otherwise, a level below 2.8 mmol/L after not eating or following exercise may be used. In newborns, a level below 2.2 mmol/L, or less than 3.3 mmol/L if symptoms are present, indicates hypoglycemia. Other tests that may be useful in determining the cause include insulin and C peptide levels in the blood. Among people with diabetes, prevention is by matching the foods eaten with the amount of exercise and the medications used; when people feel their blood sugar is low, testing with a glucose monitor is recommended. Some people have few initial symptoms of low blood sugar, frequent routine testing in this group is recommended. Treatment of hypoglycemia is by taking dextrose. If a person is not able to take food by mouth, glucagon by injection or in the nose may help; the treatment of hypoglycemia unrelated to diabetes includes treating the underlying problem as well and a healthy diet. The term "hypoglycemia" is sometimes incorrectly used to refer to idiopathic postprandial syndrome, a controversial condition with similar symptoms that occur following eating but with normal blood sugar levels.

Hypoglycemic symptoms and manifestations can be divided into those produced by the counterregulatory hormones triggered by the falling glucose, the neuroglycopenic effects produced by the reduced brain sugar. Shakiness, nervousness Palpitations, tachycardia Sweating, feeling of warmth Pallor, clamminess Dilated pupils Hunger, borborygmus Nausea, abdominal discomfort Headache Abnormal thinking, impaired judgment Nonspecific dysphoria, depression, exaggerated concerns Feeling of numbness and needles Negativism, belligerence, rage Personality change, emotional lability Fatigue, apathy, daydreaming, sleep Confusion, memory loss, lightheadedness or dizziness, delirium Staring, glassy look, blurred vision, double vision Flashes of light in the field of vision Automatic behavior known as automatism Difficulty speaking, slurred speech Ataxia, sometimes mistaken for drunkenness Focal or general motor deficit, hemiparesis Headache Stupor, abnormal breathing Generalized or focal seizuresNot all of the above manifestations occur in every case of hypoglycemia.

There is no consistent order to the appearance of the symptoms, if symptoms occur. Specific manifestations may vary by age, by severity of the hypoglycemia and the speed of the decline. In young children, vomiting can sometimes accompany morning hypoglycemia with ketosis. In older children and adults, moderately severe hypoglycemia can resemble mania, mental illness, drug intoxication, or drunkenness. In the elderly, hypoglycemia can produce a hard-to-define malaise; the symptoms of a single person may be similar from episode to episode, but are not so and may be influenced by the speed at which glucose levels are dropping, as well as previous incidents. In newborns, hypoglycemia can produce irritability, myoclonic jerks, respiratory distress, apneic episodes, hypothermia, hypotonia, refusal to feed, seizures or "spells." Hypoglycemia can resemble asphyxia, sepsis, or heart failure. In both young and old people with hypoglycemia, the brain may habituate to low glucose levels, with a reduction of noticeable symptoms despite neuroglycopenic impairment.

In insulin-dependent diabetic people this phenomenon is termed hypoglycemia unawareness and is a significant clinical problem when improved glycemic control is attempted. Another aspect of this phenomenon occurs in type I glycogenosis, when chronic hypoglycemia before diagnosis may be better tolerated than acute hypoglycemia after treatment is underway. Hypoglycemic symptoms can occur when one is sleeping. Examples of symptoms during sleep can include damp bed clothes from perspiration. Having nightmares or the act of crying out can be a sign of hypoglycemia. Once the individual is awake they may feel tired, irritable, or confused and these may be signs of hypoglycemia as well. In nearly all cases, hypoglycemia, severe enough to cause seizures or unconsciousness can be reversed without obvious harm to the brain. Cases of death or permanent neurological damage occurring with a single episode have involved prolonged, untreated unconsciousness, interference with breathing, severe concurrent disease, or some other type of vulnerability.

Ruth Frow

Ruth Frow was a peace activist and historian of the labour movement. She co-founded the Working Class Movement Library in Salford, a collection of material associated with labour and working class history. Ruth Engel was born on 28 July 1922 in St John's Wood in London, her father, Leon Alfred Mayer Engel, was a concert pianist and a traveling sales representative in embroideries.
