Diabetic ketoacidosis (DKA) is a serious condition that can occur in people with diabetes, particularly those with Type 1 diabetes. It happens when the body doesn't have enough insulin to use glucose for energy, leading to the breakdown of fat for fuel. This process produces acids called ketones, which can build up in the blood and make it acidic. Symptoms of DKA include excessive thirst, frequent urination, nausea, abdominal pain, and confusion. If left untreated, DKA can lead to severe complications, including coma or even death. Prompt medical treatment is essential to restore insulin levels and balance the body's chemistry.
