Diabetic ketoacidosis (DKA) is a serious and life-threatening complication of diabetes. It occurs when the body is unable to produce enough insulin, leading to a buildup of acids called ketones in the blood. This typically happens when blood sugar levels are too high for a prolonged period. DKA is most common in people with type 1 diabetes, but it can also occur in people with type 2 diabetes, although it is less common and less severe in the latter. The condition can be triggered by factors such as illness, injury, missed insulin doses, or stress. Symptoms of DKA include excessive thirst, frequent urination, deep and rapid breathing, dehydration, and fruity-smelling breath. Treatment for DKA usually takes place in the hospital and involves insulin therapy, fluid replacement, and electrolyte correction. It is important to manage diabetes through proper diet, medication, and self-care to prevent DKA.
