Diabetic ketoacidosis (DKA) is a serious complication of diabetes that occurs when the body produces high levels of ketones due to a lack of insulin. It is most commonly seen in individuals with type 1 diabetes but can also occur in those with type 2 diabetes. DKA is characterized by high blood sugar levels, dehydration, and an accumulation of acidic ketones in the blood, leading to symptoms such as frequent urination, thirst, nausea, vomiting, abdominal pain, and confusion. If left untreated, DKA can progress to a life-threatening condition, causing severe complications such as organ failure and coma. Treatment for DKA usually involves hospitalization, where fluids, electrolytes, and insulin are administered to stabilize blood sugar levels and reverse the acidosis. Prevention of DKA involves monitoring blood sugar levels regularly, taking insulin as prescribed, and seeking medical attention if symptoms of DKA develop.
