This document discusses ketosis and ketoacidosis, two conditions related to high levels of ketones in the blood. Ketosis occurs when the body burns fat for energy instead of carbohydrates, causing ketones to be produced and excreted in urine, while ketoacidosis is a life-threatening complication that develops when ketone levels become dangerously high, lowering the blood's pH. The document recommends monitoring ketone levels and seeing a doctor immediately if symptoms of ketoacidosis appear in order to receive treatment and prevent serious health issues.
