Final answer:
Breath that smells like nail polish remover is indicative of diabetic ketoacidosis, a life-threatening complication of diabetes wherein the body breaks down fats, producing ketone bodies like acetone which are exhaled.
Step-by-step explanation:
One might notice a breath that smells like nail polish remover during a dangerous condition known as diabetic ketoacidosis (DKA). This occurs when the body starts to break down fats at an excessive rate, producing ketones, which are then released into the bloodstream. When the concentration of ketones is high, the blood becomes acidic, leading to ketoacidosis. Acetone, a type of ketone body that has a characteristic fruity smell similar to nail polish remover, can be exhaled, indicating the presence of this condition. Other symptoms of DKA include deep, rapid breathing, a dry mouth, flushed face, nausea, vomiting, and stomach pain. Immediate medical attention is necessary to treat this emergency, often involving hydration, electrolyte replacement, and insulin administration.
