Overview

Diabetic Ketoacidosis

Diabetic ketoacidosis, or DKA, is a life-threatening diabetes complication in which insufficient insulin leads to ketone accumulation and increased blood acidity. It occurs most often in type 1 diabetes but can also occur in type 2 diabetes. Warning signs include thirst, frequent urination, vomiting, abdominal pain, deep or rapid breathing, fruity-smelling breath, and increasing drowsiness or confusion. Suspected DKA requires emergency assessment.

Major Depressive Disorder

Major depressive disorder is a mood disorder characterized by persistent depressed mood or loss of interest that interferes with daily life. Symptoms may affect sleep, appetite, energy, concentration, and functioning and generally persist for at least two weeks. Depression can affect people of different ages and may require ongoing treatment.

Diagnosis

Diabetic Ketoacidosis

Clinicians assess glucose, ketones—particularly blood beta-hydroxybutyrate—and blood acidity using pH or bicarbonate. Electrolytes, kidney function, and possible precipitants are also evaluated. Diagnosis depends on the combined findings, not glucose alone: DKA can occur without markedly elevated glucose.

Major Depressive Disorder

Diagnosis is based on symptoms, their duration, their effect on daily functioning, medical history, and clinical assessment. Major depression generally involves depressed mood or loss of interest lasting at least two weeks along with other symptoms. Healthcare professionals may also assess for medical conditions, medicines, or substance use that could contribute to symptoms.

Prevention

Diabetic Ketoacidosis

People with diabetes can reduce risk by following their existing prescribed care plan, monitoring glucose as advised, and having an agreed plan for illness. That plan should explain when to check ketones and when to contact the healthcare team or seek urgent help.

Major Depressive Disorder

Major depressive disorder cannot always be prevented. Maintaining supportive social connections, regular physical activity, adequate sleep, healthy routines, and appropriate management of chronic medical conditions may support mental well-being. Recognizing persistent changes in mood or functioning and seeking professional help early may reduce the impact of depression.

Risk Factors

Diabetic Ketoacidosis

Risk is greater when diabetes is accompanied by insufficient insulin, acute illness, or disrupted insulin delivery. Some medicines, including SGLT2 inhibitors, can increase DKA risk. DKA is not restricted to people who already know they have diabetes.

Major Depressive Disorder

Risk of major depressive disorder may increase with family history, previous episodes of depression, stressful or traumatic life events, certain chronic medical conditions, long-term pain, substance or alcohol use, and other mental health conditions. Depression can occur even without an identifiable risk factor or family history.
