What are the obvious symptoms of ketoacidosis?

Ketoacidosis is caused by abnormal metabolic function in the patient's body, resulting in the inability of ketone bodies to be excreted from the body and a large accumulation of ketone bodies. Patients often experience obvious symptoms such as nausea and vomiting, shortness of breath, and loss of appetite, and may be accompanied by symptoms such as excessive fatigue and lethargy.
