garlicky smell on type 2 diabetic with heart disease - don't know how to post at adult part

My apologies for posting again in the juvenille section, but I don't know how to post this in the adult section.

I noticed a strong garlicy smell on my husband.  He is a type 2 diabetic and has had 2 heart attacks, one resulting in 2 stints.  This smell came on suddenly last night and filled the entire house.  It's not a sweet smell and he said he did not eat garlic.  In fact he didn't each much at all yesterday.  It almost smelled a bit like garlic and alcohol.  He does not drink.

One of the most common causes of body odor in diabetes is Keotacidosis [key-oh-aht-tee-doh-sis]. This is particularly true when a person's blood sugars are poorly controlled. This condition not only gives the breath a fruity smell but can also cause a distinctive body odor. This condition is considered to be a medical emergency and should be treated right away. Take your husband to ER now.
