Sweet smelling body odor

My husband has a sickly sweet body odor after drinking even one drink. I have a decent sense of smell, and can tell he's had even one beer after about 30 minutes if he comes within 2 feet of me. on nights he drinks a lot, the entire room takes on the sweet smell.
does he need to see a doctor? half the people in my family are drinkers, and i've never smelt this until i met him
thanks

hi. sounds like ketoacidosis which is a condition from poor nutrition and alcohol intake. it is also prevalent in some diabetics. it can be indicative of underlying issues which could be checked for in lab tests. a doctor visit would be advisable. take care,  gm
