My husbands breath has a strong formaldehyde smell after he drinks as little as one beer.  Ive not noticed this in other people after they drink.  Im wondering if this is a sign hes damaged or is damaging his liver?  Hes 48 and drinks 2-3 beers/day or a bottle of wine.  Some days he does not drink and other days he drinks more.  He seems otherwise healthy and checks out fine at his annual physicals.
Hi thanks for contacting Chat Doctor ... According to your complaint it doesn't seems severe chronic liver disease. In hepatic encephalopathy like chronic liver condition foul smell can come from mouth . As a result of sulfur containing amino acids like merchantman... But it usually occurs in patient of cirrhosis like chronic liver disease... He should limit alcohol Chat Doctor. . The maximum safe limit is 20 gm/liter. Here advise her to maintain oral hogan with two time brushing after lunch and dinner... Water taken more... Oral mouthwash can be used.... If still smell there proper physical examination needed by doctor... Take care...Don't worry... Regular USG study and liver enzymes study useful for identifying liver pathology...
