DH keto breath after drinking

[AtomHeartMotherOfGod]

I'm hoping someone will give me confidence to act more decisively or relax a bit.

Basically, I will often smell a sweet 'keto breath' on my DH after he's had a night drinking. He fairly religiously has 4 alcohol free days each week, but then drinks a whole bottle of wine or more on Friday/ Saturday, so it's arguably binge drinking and I'm not sure if it's better for him than little amounts when he feels like it.

I'm particularly worried given his family and personal medical history. He does have annual medicals that never flag up anything diabetes related, but recent family history includes pancreatic cancer, kidney failure and high cholesterol (his is cuspy); he carries all his fat viscerally; he gets gout and has markers for high urea; and he was previously diagnosed with fatty liver (a concerted and long lasting health drive reversed this though).

He is proud of his health changes, as he should be, and they have improved many previous issues, but he is unable to take criticism very well in general. I'm concerned, not criticising but think he will see it more as the latter if I tell him to talk to a doctor about this one thing. Should I leave it?

Should he see a doctor about having bad breath? No I'd say he should visit a dentist.
Or tell him to go brush and use mouthwash.

Otherwise I don't really see a major issue?

Thank you but he doesn't have chronic bad breath, I just notice this particular 'sweet breath' after any night when he's drunk a whole bottle.

I knew that ketoacidosis could be brought on by drink, and investigating further, found that it can also be a symptom of pancreatitis. The blood tests done at the annual screen do not include those that can show there's a problem with the pancreas (amylase and lipase).

To be honest, I might just tell him to discuss it with a doctor and be safe. He can get so defensive I thought I'd ask here first to see if I was being ridiculous, but I'll put up with it.

Stop googling!
