What is a common chief complaint in patients with DKA?

In patients with diabetic ketoacidosis (DKA), a common chief complaint is persistent vomiting, particularly in those with a history of diabetes mellitus. DKA is characterized by uncontrolled hyperglycemia, acidosis, and ketone production, often triggered by factors such as infection, missed insulin doses, or other stressors. The metabolic derangements in DKA lead to nausea and vomiting, which can be significant and distressing for the patient.

Persistent vomiting occurs because the body's attempt to rid itself of excess ketones and stabilize the acid-base balance can lead to gastrointestinal distress. Patients might also present with other symptoms like polyuria, polydipsia, and a fruity odor on their breath due to ketosis.

In contrast, while severe abdominal pain and confusion can occur in some patients, these symptoms are not as directly correlated with DKA as vomiting is. Dry mouth without vomiting is less typical since the dehydration caused by diabetes and the ensuing metabolic state usually has associated symptoms such as vomiting.
