Disease description:

My husband has recently been drooling excessively while sleeping, and the saliva has an unpleasant odor. He also has dark yellow urine when urinating. What could be causing the excessive drooling, foul-smelling saliva, halitosis, and dark yellow urine?

Excessive salivation with foul-smelling saliva—leading to halitosis—and dark yellow urine may result from gastrointestinal digestive dysfunction, inflammation of the tonsils or pharynx, or oral diseases. To alleviate these symptoms, avoid “heat-inducing” (i.e., spicy, fried, or overly rich) and hard-to-digest foods; instead, increase intake of fruits and vegetables rich in vitamins.
