[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. [2]
Symptoms of diabetic hypoglycemia, when they occur, are those of hypoglycemia: neuroglycopenic, adrenergic (that is, activating adrenergic receptors, resulting e.g. in fast heartbeat), and abdominal. Symptoms and effects can be mild, moderate or severe, depending on how low the glucose falls and a variety of other factors.
In both young and old individuals, the brain may habituate to low glucose levels with a reduction of noticeable symptoms, sometimes despite neuroglycopenic impairment. In insulin-dependent diabetic patients this phenomenon is termed hypoglycemia unawareness and is a significant clinical problem when improved glycemic control is attempted.
Endocrinologists share uncommon symptoms of diabetes that may indicate type 1, type 2, or prediabetes. Some signs include infections and dry skin.
Ketotic hypoglycemia classically presents in male young children, typically between the ages of 10 months and 6 years, in the morning after a prolonged overnight fast. Symptoms include those of neuroglycopenia, ketosis, or both. [6] [7] Neuroglycopenic symptoms usually include lethargy and malaise, but may include unresponsiveness or seizures.
hypoglycemia Whipple's triad is a collection of three signs (called Whipple's criteria ) that suggests that a patient's symptoms result from hypoglycaemia that may indicate insulinoma . The essential conditions are symptoms of hypoglycaemia, low blood plasma glucose concentration , and relief of symptoms when plasma glucose concentration is ...
Symptoms vary according to individuals' hydration level and sensitivity to the rate and/or magnitude of decline of their blood glucose concentration. [citation needed] A crash is usually felt within four hours of heavy carbohydrate consumption. Along with the symptoms of hypoglycemia, symptoms of reactive hypoglycemia include: [7] [8] [9]
Hyperinsulinemic hypoglycemia describes the condition and effects of low blood glucose caused by excessive insulin. Hypoglycemia due to excess insulin is the most common type of serious hypoglycemia. It can be due to endogenous or injected insulin.
