This is a shortened version of the seventeenth chapter of the ICD-9: Diseases of the Digestive System. It covers ICD codes 800 to 999. The full chapter can be found on pages 473 to 546 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Hypoglycemia can also be caused by sulfonylureas in people with type 2 diabetes, although it is far less common because glucose counterregulation generally remains intact in people with type 2 diabetes. Severe hypoglycemia rarely, if ever, occurs in people with diabetes treated only with diet, exercise, or insulin sensitizers.
[3] [2] Although 70 mg/dL (3.9 mmol/L) is the lower limit of normal glucose, symptoms of hypoglycemia usually do not occur until blood sugar has fallen to 55 mg/dL (3.0 mmol/L) or lower. [ 3 ] [ 2 ] The blood-glucose level at which symptoms of hypoglycemia develop in someone with several prior episodes of hypoglycemia may be even lower.
Idiopathic hypoglycemia is a medical condition in which the glucose level in the blood (blood glucose) is abnormally low due to an undeterminable cause. This is considered an incomplete and unsatisfactory diagnosis by physicians and is rarely used by endocrinologists , as it implies an unfinished diagnostic evaluation.
Manifestations of hyperinsulinemic hypoglycemia vary by age and severity of the hypoglycemia. In general, most signs and symptoms can be attributed to (1) the effects on the brain of insufficient glucose (neuroglycopenia) or (2) to the adrenergic response of the autonomic nervous system to hypoglycemia. A few miscellaneous symptoms are harder ...
A 2004 statement by the European Society for Paediatric Endocrinology and the Lawson Wilkins Pediatric Endocrine Society (for children) uses slightly different cutoffs, where mild DKA is defined by pH 7.20–7.30 (bicarbonate 10–15 mmol/L), moderate DKA by pH 7.1–7.2 (bicarbonate 5–10) and severe DKA by pH<7.1 (bicarbonate below 5).
Hypoglycemia enjoys a popular position in the public's eye as a non-specific medical condition that frequently provides an explanation for the varied symptoms that occur in daily life. [3] These doctors cautioned against the over-diagnosis of reactive hypoglycemia. They said "both physicians and the public deserve major re-education."
Impaired fasting glucose is often without any signs or symptoms, other than higher than normal glucose levels being detected in an individual's fasting blood sample.There may be signs and symptoms associated with elevated blood glucose, though these are likely to be minor, with significant symptoms suggestive of complete progression to type 2 diabetes.
