What is hypoglycaemia (low blood glucose)?
Hypoglycaemia or low blood glucose is a condition in which the level of glucose (sugar) in the blood, drops below a certain point (about 2.5mmol/l).
The condition manifests itself by a number of symptoms that usually disappear 10 to 15 minutes after eating sugar.
People differ slightly in the exact level of blood glucose at which they begin to feel symptoms of low blood sugar.
What causes hypoglycaemia?
Insulin is normally produced in the pancreas and helps the cells in the body absorb glucose from the blood. Normally, the glucose level rises after a meal.
Too much insulin in the blood and other diseases can cause hypoglycaemic episodes (also known as 'hypos').
What can cause hypoglycaemic episodes in non-diabetic patients?
Too much insulin in the blood:
reactive hypoglycaemia (see below)
a tumour – very often benign – in the insulin-producing pancreas. This is a very rare condition indeed
an overdose of insulin or diabetic tablets either by mistake or on purpose.
Other diseases:
a disease in the adrenal glands (Addison's disease)
a weakened pituitary gland
a severe reduction in liver function
patients who have had their stomach removed
sometimes cancer
fasting, malnutrition
following alcohol ingestion.
Reactive hypoglycaemia
Reactive hypoglycaemia is possibly the most common reason for hypoglycaemia in non-diabetics but is often overdiagnosed.
This form of hypoglycaemia is probably caused by an overproduction of insulin from the pancreas after a large meal with a lot of carbohydrates.
The insulin can still be detected even after several hours, although the level should be back to normal at this time. This condition is probably most common in overweight people and those with Type 2 diabetes, where the large demand for insulin can sometimes cause too much insulin to be produced in the pancreas. There is some evidence to suggest that reactive hypoglycaemia can precede Type 2 diabetes.
What happens during a hypoglycaemic episode?
Hypoglycaemia can cause some or all of the following symptoms:
paleness
trembling
perspiration
a feeling of weakness
rapid heartbeat
hunger
agitation
difficulty concentrating
irritability
fatigue
blurred vision
temporary loss of consciousness
convulsions
coma.
These symptoms will often occur about three to four hours after a meal.
What can you do yourself?
If hypoglycaemia is suspected with the symptoms similar to those above coming on three to four hours after a meal and going away after eating sugar, it should be confirmed that the symptoms are caused by low blood glucose.
Many people say they have hypoglycaemia without having low blood glucose diagnosed!
The doctor should be contacted and, if possible, a home blood glucose apparatus obtained.
When the symptoms occur, measure the blood glucose level. If all three of the criteria below are met, you should be referred for further examination at a hospital.
Blood glucose level below 2.5mmol/l (millimole per litre) – or sometimes slightly higher.
Some or all of the symptoms listed above.
The symptoms go away within 10 minutes of eating sugar.
How is the diagnosis made?
The diagnosis is made by measuring the blood glucose level. If the glucose level is below 2.5mmol/l, you have hypoglycaemia. If a tumour in the pancreas is suspected, the patient is admitted to a hospital for observation for three days, where the glucose level is closely monitored.
If this drops below a certain point, the insulin level in the blood is measured. If this is high, it suggests a tumour in the pancreas, which will be looked for, and if found, removed.
Exercise and diet
Exercise lowers the blood glucose level but will normally not cause hypoglycaemic episodes in otherwise healthy people.
If symptoms of hypoglycaemia are experienced during sport or exercise, try eating some complex carbohydrates - starch, pasta for example - before beginning. During the exercise consume simple carbohydrates like glucose, in sports drinks for example.
When reactive hypoglycaemia has been diagnosed, the most important thing to do is to change the diet. It should consist of a lot of complex carbohydrates - potatoes, rice, pasta, etc - and be divided into more, but smaller meals - breakfast, lunch, dinner and three in-between meals - to avoid the big fluctuations in the insulin secretion from the pancreas.
How is hypoglycaemia treated?
Reactive hypoglycaemia is treated with diet changes as described above. If a tumour in the pancreas is found, it is usually removed. However, if this cannot be done, the condition can be controlled by injecting sandostatin (Octreotide). Weakened adrenal and pituitary glands are treated with medication.
