Brief Summary:
Recent data suggest that the trillions of bacteria in the investigators gastrointestinal tracts (gut microbiota) can function as an environmental factor that modulates the amount of body fat. Obese individuals have an altered gut microbiota and germ-free mice are resistant to developing diet-induced obesity and have lower fasting insulin and glucose and improved glucose tolerance. Administration of the probiotic bacterium Lactobacillus strain in fermented milk for 12 weeks reduced adiposity and body weight in obese adults, possibly by reducing lipid absorption and inflammatory status. However, there are no studies to the investigators knowledge that address whether probiotic supplementation improves glucose metabolism in type 2 diabetes patients.

Arm Intervention/treatment
Lactobacillus reuteri
Dietary supplementation with Lactobacillus reuteri DSM 17938
Dietary Supplement: Lactobacillus reuteri DSM 17938
Ordinary treatment against type 2 diabetes is supplemented with one tablet containing 100 million Lactobacillus reuteri DSM 17398, once daily for 12 weeks

Primary Outcome Measures :
  1. HOMA index [ Time Frame: 12 weeks ]
    To determine improved glucose handling and insulin sensitivity in adult type 2 diabetic patients supplemented with the probiotic L. reuteri DSM 17938 over a 12 week period, we assess insulin sensitivity via the HOMA index (fp-Glucose x fS-Insulin divided by 22.5).

Secondary Outcome Measures :
  1. Changes in diabetes medication and hypoglycemia events [ Time Frame: 12 weeks ]
    We monitor changes in diabetes medication and hypoglycemia events. Dosages of medication with oral hypoglycemic agents and number of insulin units per 24 hrs and number of hypoglycemia events will be registered in diaries.
