From the Guidelines

Metabolic decompensation in a diabetic patient is considered a serious deterioration in metabolic control, typically manifesting as diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS), and is characterized by severely elevated blood glucose levels, metabolic acidosis, and ketone production. This condition can lead to life-threatening complications if not promptly addressed. The warning signs of metabolic decompensation include excessive thirst, frequent urination, nausea, vomiting, abdominal pain, fruity-smelling breath, confusion, and in severe cases, loss of consciousness 1.

Key Characteristics of Metabolic Decompensation

  • Severely elevated blood glucose levels (typically above 250 mg/dL for DKA and often exceeding 600 mg/dL for HHS)
  • Metabolic acidosis and ketone production in DKA
  • Extreme hyperglycemia causing severe dehydration and electrolyte imbalances in HHS
  • Warning signs include excessive thirst, frequent urination, nausea, vomiting, abdominal pain, fruity-smelling breath, confusion, and in severe cases, loss of consciousness

Treatment and Management

Treatment of metabolic decompensation requires immediate medical attention with:

  • Intravenous fluids
  • Insulin therapy (typically regular insulin at 0.1 units/kg/hour)
  • Electrolyte replacement, particularly potassium Patients should seek emergency care if they experience symptoms of decompensation, especially when accompanied by illness, infection, or medication non-adherence 1.

Prevention and Monitoring

To prevent metabolic decompensation, it is essential to:

  • Monitor blood glucose levels regularly
  • Adjust insulin doses as needed
  • Seek medical attention promptly if symptoms of decompensation occur
  • Educate patients on the recognition and management of hypoglycemia and hyperglycemia 1.

Important Considerations

Metabolic decompensation can occur due to various factors, including insufficient insulin, illness, infection, or medication non-adherence. It is crucial to identify patients at high risk for DKA, such as those with type 1 diabetes, and to implement a policy requiring staff to notify a physician of all blood glucose results outside of a specified range 1.

From the FDA Drug Label

Hyperglycemia, diabetic ketoacidosis, or hyperosmolar coma may develop if the patient takes less Humulin R U-100 than needed to control blood glucose levels Early signs of diabetic ketoacidosis include glycosuria and ketonuria Polydipsia, polyuria, loss of appetite, fatigue, dry skin, abdominal pain, nausea and vomiting and compensatory tachypnea come on gradually, usually over a period of some hours or days, in conjunction with hyperglycemia and ketonemia.

Metabolic Decompensation in a diabetic patient is considered to occur when the patient develops hyperglycemia, diabetic ketoacidosis, or hyperosmolar coma due to inadequate control of blood glucose levels. This can be characterized by symptoms such as:

  • Glycosuria and ketonuria
  • Polydipsia and polyuria
  • Loss of appetite
  • Fatigue
  • Dry skin
  • Abdominal pain
  • Nausea and vomiting
  • Compensatory tachypnea 2

From the Research

Definition of Metabolic Décompensation

Metabolic décompensation in a diabetic patient refers to a state of severe metabolic imbalance, characterized by hyperglycemia, ketosis, and acidosis. This condition can occur in both type 1 and type 2 diabetes mellitus [(3,4,5)].

Characteristics of Metabolic Décompensation

The key features of metabolic décompensation include:

  • Hyperglycemia: elevated blood glucose levels [(3,4,6,5,7)]
  • Ketosis: presence of ketone bodies in the blood [(3,4,5,7)]
  • Acidosis: metabolic acidosis, which can lead to serious complications [(3,4,5,7)]
  • Dehydration: due to osmotic diuresis and inadequate fluid intake [(4,6,5,7)]

Types of Metabolic Décompensation

There are two main types of metabolic décompensation:

  • Diabetic ketoacidosis (DKA): characterized by hyperglycemia, ketosis, and acidosis [(3,4,6,5,7)]
  • Hyperosmolar hyperglycemic state (HHS): characterized by severe hyperglycemia, hyperosmolality, and little or no ketosis [(3,4,6,5,7)]

Precipitating Causes

Common precipitating causes of metabolic décompensation include:

  • Infection [(4,5)]
  • Insulin omission or deficiency [(3,4,5)]
  • Undiagnosed diabetes 5
  • Substance abuse 5
