HYPOGLYCEMIA

Hypoglycemic states:
Hypoglycaemia is condition we have low glucose concentration than normal in blood. Noemal glucose around 5mmol/L. this cause by  regulation disorder by decrease income of glucose and gluconeogenesis , increase glucose disposal through exercise and hyperinsulinism
It can be :
  •   Fasting hypoglycaemia
  •    Insulinoma
  •  Postprandial hypoglycaemia especially after stomach resections.

What is etiology for hypoglycaemia:
  1. Nutrition disorders

·         This is because of severe fasting and mental anorexia. This cause decrease in substrate offer causing glycogen production and decrease gluconeogenesis.
2                 2.     Conditions based on decrease glucose production

·         Shortage of contra regulatory hormones which are hypothyroidism, renal cortex insufficiency, glucagon defcit and hypothyreosis.
·         Serious liver disease cause decrease amount of glycogen and gluconeogenesis
·         Alcohol excess in undernourished people or after exercise causing inhibition of gluconeogenesis because substrate for glucose formation is use to metabolise alcohol.
·         Enzymopathies.Lack of certain enzyme to synthesis glucose

                  3.  Increase glucose disposal by hyperinsulinemia.

·         This can be congenital insulinemia, infant diabetic mothers(due to insulin hypersecretion as a response to hyperglycemia.
·         Can also cause by dumping syndrome, where food we eat by pass from stomach to small intestine rapidly causing our intestine cannot digest what we eat.
·         Overdose of insulin in diabetic patients.
·         Therapy with sulphonylurea derivates. Cause increase insulin secretion.
·         Insulinoma, which is tumour of B cells.



Clinical picture:
Hypoglycaemia occur when glucose level below 3.3mmol/L, serious below 2.5mmol/L
1  Adrenergic reaction activation:
·         Excessive sweating
·         Trembling
·         Tachycardia
2 Brain hypoglycaemia
·         Fatigue
·         Mental confusion, cognitive disorders
·         Irritability up to seizure, aggresivity, slurred speech
·         Unconsciousness

Therapy:

60ml og 40% glucose oral or intavenous
