Diabetic ketoacidosis

Diabetic Ketoacidosis' (DKA) is a serious metabolic condition that is a complication of uncontrolled diabetes. It is characterized by a shift in the body's acid-base balance towards the acidic side due to the loss of bases or retention of non-carbonic acids. This imbalance is accompanied by an accumulation of ketone bodies in body tissues and fluids.

Overview

DKA occurs predominantly in patients with type 1 diabetes, but it can also affect those with type 2 diabetes under certain circumstances, such as severe illness. It is a critical condition that can lead to coma or even death if not promptly and adequately treated.

The condition arises when the body's cells cannot use glucose for energy due to a deficiency of insulin, a hormone produced by the pancreas that helps glucose enter cells. As a result, the body starts breaking down fats for energy, leading to the accumulation of acidic compounds called ketones in the bloodstream, a state known as ketosis. Meanwhile, the unused glucose builds up in the blood, causing high blood sugar levels (hyperglycemia).

Symptoms

Symptoms of DKA may develop rapidly, often within 24 hours. These can include:

• Frequent urination
• Excessive thirst
• High levels of ketones in the urine
• High blood sugar levels
• Fatigue or drowsiness
• Nausea or vomiting
• Difficulty breathing
• Fruity scent on the breath
• Confusion or difficulty concentrating

Causes and Risk Factors

DKA often results from:

• Inadequately managed diabetes
• Inadequate insulin dosage
• Infection or other illnesses
• Untreated type 1 diabetes

Risk factors for DKA include:

• Type 1 diabetes
• Missed insulin doses
• Physical or emotional stress
• Certain medications

Diagnosis and Treatment

DKA is diagnosed through blood tests that measure blood sugar, blood ketone, and acid-base levels. Urine tests may also be performed to check for ketones.

Treatment for DKA typically involves:

• Rehydration with intravenous (IV) fluids to treat dehydration and dilute the excess glucose in the blood
• Insulin therapy to suppress the production of ketones
• Electrolyte replacement to replenish the body’s depleted essential minerals
• Treating the underlying cause, such as infection

Prompt recognition and treatment of DKA can save lives. People with diabetes should be aware of the risk factors and symptoms of DKA and seek immediate medical attention if they suspect this condition.
