What is a potential indicator of high blood sugar levels?

A fruity-smelling breath is a key indicator of high blood sugar levels, particularly in individuals who may be experiencing diabetic ketoacidosis (DKA). When the body lacks sufficient insulin to convert glucose into energy, it begins to break down fat for fuel. This process produces ketones, which can lead to a buildup of acids in the blood and result in a distinct fruity odor on the breath, reminiscent of nail polish remover or overripe fruit. Recognizing this symptom is vital, as it can help prompt timely medical intervention to address the underlying issue of uncontrolled blood sugar levels.

Other indicators, such as clumsy movements or pale skin with sweating, typically point to different medical conditions like hypoglycemia (low blood sugar) or general distress. Sudden dizziness may also arise from various factors, including dehydration or rapid changes in blood sugar. However, the specific fruity breath is strongly associated with the metabolic changes that occur with high blood sugar levels and is a critical symptom for individuals managing diabetes to monitor closely.
