Adam Frosh, consultant surgeon at Lister Hospital in Britain said Daily Mail says sour breath may be caused by acid reflux, sweet breath may indicate diabetes, and musty odor may indicate liver cirrhosis.
The doctor explained that sour breath could be a sign of acid reflux. This is a condition in which acid normally found in the stomach is thrown into the esophagus, the muscular tube that connects the mouth and stomach. A faint musty odor can often be detected in patients with severe cirrhosis, a disease characterized by damage to the structure of the liver due to proliferation of connective tissue (fibrosis). The main causes that lead to the development of liver cirrhosis include excessive consumption of alcohol, exposure to certain drugs and poisoning with industrial poisons.
A sweet, “fruity” smell is a hallmark of type 1 diabetes, an autoimmune disease characterized by insufficient insulin production and high blood sugar levels. The odor is caused by diabetic ketoacidosis, a complication in which the body begins burning fat because it cannot use sugar for energy. This produces chemicals called ketones, which have a sweet, “fruity” odor (or acetone) and are released during breathing and sweating.
