Correct. When acid levels reach a critical point, any combination of the symptoms mentioned [weakness, shortness of breath, rapid breathing, abdominal pain, nausea, vomiting, frequent urination, and dehydration] can occur.
The combination of high acid (ketones), high sugar, and low electrolytes are the cause for these symptoms and hence the name Diabetic KetoAcidosis (DKA).
Each person is unique and can present differently with Diabetic KetoAcidosis so this list is not meant to be a complete guide but more of a heads up.
It is important to have Ketone stripes at home to test for ketone levels if you are having any symptoms or suspect you may be in diabetic ketoacidosis as this is a medical emergency. Use as Instructed!
