Diabetic emergencies occur when blood sugar levels become dangerously high or low, requiring immediate medical attention. Common emergencies include diabetic ketoacidosis (DKA), where high blood sugar leads to a buildup of acids in the blood, and hypoglycemia, where blood sugar drops too low, causing confusion, seizures, or unconsciousness. Symptoms of these emergencies may include extreme thirst, frequent urination, nausea, sweating, or disorientation. Quick intervention, such as administering insulin for high blood sugar or glucose for low blood sugar, is critical. Proper diabetes management and regular monitoring can help prevent these life-threatening situations.
सारांश
- Diabetic ketoacidosis (DKA) is characterized by hyperglycemia, ketosis, and metabolic acidosis. It results from insulin deficiency, leading to increased lipolysis and the production of keto acids. Common symptoms include nausea, vomiting, abdominal pain, thirst, and rapid breathing. DKA is commonly seen in type 1 diabetics who discontinue insulin.
- The management of DKA primarily involves IV fluid resuscitation, insulin infusion, and potassium replacement. Fluid resuscitation is crucial due to dehydration. Insulin infusion aims to reduce blood sugar levels. Potassium replacement is essential because the body experiences a potassium deficit. Bicarbonate is generally not recommended unless the pH is very low.
- Hyperglycemic hyperosmolar state (HHS) is often seen in type 2 diabetics, especially the elderly. While it involves hyperglycemia and dehydration, it does not typically present with acidosis or significant ketosis. Patients with HHS are often more drowsy and may be comatose. Volume depletion is more severe in HHS than in DKA.
- The treatment of HHS includes IV fluid resuscitation and insulin infusion. Fluid selection needs to be carefully considered based on the patient's sodium levels and hemodynamic stability. Monitoring cardiac function is important to prevent fluid overload. Insulin requirements are generally lower in HHS compared to DKA.
- Hypoglycemia, characterized by low blood sugar, can manifest with autonomic (e.g., sweating, tremors) or neuroglycopenic symptoms (e.g., confusion, seizures). It can occur due to excessive insulin, missed meals, or certain medications, notably sulfonylureas. Hypoglycemic unawareness, the absence of warning symptoms, increases the risk of severe events.
- Management of hypoglycemia involves immediate glucose administration. In patients with diabetes, it is important to counsel them on avoiding missed meals, and to be vigilant about symptoms. Non-diabetic patients with recurrent hypoglycemia should be evaluated for underlying causes, such as insulinoma. Hospital admission for observation is recommended after a hypoglycemic episode.
