Gut Bacteria in Kids With Diabetes Show Differences

Findings suggest diet might someday play preventive role, researchers say

THURSDAY, June 12, 2014 (HealthDay News) -- A new study finds that germs in the guts of young children with type 1 diabetes are different from those of other kids.

Bacteria in the guts of kids with type 1 diabetes appear less balanced than bacteria in children without diabetes, Dutch researchers reported in the June 12 issue of Diabetologia. Moreover, the nondiabetic children had higher levels of a usually beneficial kind of germ.

Germs in the gut may be important because research has linked changes in their composition to the development of type 1 diabetes, which is increasing worldwide. There has been a sharp rise in diagnoses seen in children under age 5 in particular, the researchers, from University Medical Center Groningen, said in a journal news release.

The findings suggest dietary changes might ultimately reduce the risk of developing type 1 diabetes in children with genetic risk for the disease, according to the researchers.

While more work needs to be done in determining what foods are best for ideal gut conditions, "we think a diet high in fruits and vegetables is best as these are rich in fiber and complex carbohydrates," the study authors wrote, adding simple sugars and excessive protein and animal fat may be harmful.

People with type 1 diabetes have elevated blood sugar levels because their body doesn't produce insulin, a hormone needed to convert food into energy.

The study set out to examine the makeup of gut bacteria in European children, ages 1 to 5 years old, who were recently diagnosed with type 1 diabetes. The researchers looked at DNA in fecal samples collected from 28 diabetic children and 27 similar kids without the chronic disease.

Diabetic children younger than 3 years old had higher levels of certain bacteria, but lower levels of other types thought to be beneficial, the study found.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
