If blood sugar remains higher than normal for a prolonged period, the body produces high levels of blood acids called ketones. Diabetic ketoacidosis (DKA) occurs because of the lack of insulin, an essential hormone. Instead of using the sugar for energy, which is typical, the body uses fat in the form of ketones, as fuel. When blood sugar levels are too high for too long, ketones build up in the blood. In turn, the body undergoes a chemical imbalance. Though many people today are undertaking the ketogenic diet to reach a state of ketosis, this is not the same as diabetic ketoacidosis, which is dangerous. Stress, sickness, and skipping a meal can increase ketones, but people with type 1 diabetes are even more at risk of developing the condition.
A dry mouth or the feeling of thirst that cannot be explained by physical activity or a lack of sufficient fluid intake could point to diabetes. Excessive thirst is a symptom of high blood sugar and diabetic ketoacidosis. Even without an increase in fluids, a person with diabetic ketoacidosis may find themselves needing to urinate more often.
