See PCP AND dentist : Her blood sugar levels are roughly 2x what they should be--indicating poor control of her diabetes. She needs to be seen by her pcp to get it under check. Diabetes can cause ketoacidosis, which can result in malodorous breath (and death). Once the sugar is better controlled, see the dentist to determine if she has gum disease--another common source of halitosis. The two diseases are interrelated.

Halitosis: Lots of causes for halitosis. Common ones are acid reflux and bad oral health (bad teeth and gums). Diabetes in itself probably not the cause. Her diabetes, however, is horribly out of control and she needs to see her doctor to help get it under control.

Diabetes and teeth: Your wife is at high risk of diabetes complications. She needs to be in better control of her disease. Her primary care and a diabetes counselor can help her get in better control. Oral health, particularly periodontal disease is intimately related to diabetes. So encourage her to see her dentist regularly and have her teeth cleaned every 3 months as recommended by her dentist.
