Spike In Teen Obesity Explained By Decreased Calorie Burn In Puberty

The rise in obesity rates during adolescence may be due to a substantial fall of calories burned during the rapid growth phase of puberty, finds a new study by the University of Exeter Medical School in the United Kingdom.

According to the Centers for Disease Control and Prevention, around 20 percent of adolescents age 12-19 years are obese in the United States. Obese teenagers are more likely to have prediabetes, a condition in which blood glucose levels indicate a high risk for the development of diabetes.

Adolescents who are obese are also at a greater risk for bone and joint problems, sleep apnea, social and psychological problems, and they are more likely to have risk factors for cardiovascular diseases, such as high cholesterol or high blood pressure.

How Reliable Is The Glycemic Index?

Individual response to glycemic index values vary so much that it may not be useful in indicating blood sugar response, says research published in the American Journal of Clinical Nutrition.

The glycemic index (GI) of a food indicates the speed with which blood sugar can be expected to rise after a person eats it. Each food gets a score out of 100 on the index, for example, 40 for baked beans.

Glycemic load is a measure that applies the GI to a portion of food. The glycemic load for a 150-gram serving of baked beans would be 6.

GI is used to help people with diabetes to control their blood sugar. Some food labels carry GI measurements. More recently, a number of popular diets have been based on GI. Lists are available for people to check the GI and glycemic load of different foods.

Blood Tests You Need After Age 50

 

Five Blood Tests You Need After Age 50

1. HCV for hepatitis C virus: The virus that kills more Americans than any other disease will probably surprise you: It's hepatitis C.
2. Blood glucose test for diabetes: If you're overweight and have high blood pressure and a history of diabetes in your family, you're a prime candidate for a screening test of the sugar in your blood.
3. Lipid panel for high cholesterol: If your cholesterol numbers are borderline or if you have another health condition like diabetes that would increase your risk of heart problems, you'll want to be tested.
4. Bloodwork for sexually transmitted infections: If you have a new sexual partner, multiple sexual partners, or don't typically use condoms, mention it to your doc.
5. TSH test for hypothyroidism: If your thyroid-stimulating hormone blood test reveals that you have high TSH, you have an underactive thyroid, or hypothyroidism.

Tips to diabetes for drinking alcohol

Enjoying a glass of wine, fruity margarita, or frosty pint of beer requires a little forethought if you have diabetes. Before you indulge, make sure you have a tasty appetizer or healthy salad to go along with your drink. And talk to your doctor about drinking alcohol. The answer to whether you can or should not will depend on your specific circumstances.

How Does Alcohol Affect Blood Sugar?

The way alcohol affects your blood sugar comes down to whether you’ve eaten, and how much and how often you drink. A standard drink contains 0.6 fluid ounces of alcohol. This means that a 12 ounce beer (about 5% alcohol) is equivalent to a 5 ounce glass of your average table wine (about 12% alcohol) or a shot of hard liquor such as vodka. Here’s the scoop on how much and how often:

• When you have an occasional drink with food, alcohol generally has little effect on your blood sugar. This is the safest way to enjoy alcohol.
• When you have an occasional drink without any food, alcohol can cause your blood sugar to fall to dangerously low levels. You should never drink alcohol on an empty stomach.
• If you are a habitual drinker (3 to 4 drinks a day), alcohol increases your blood sugar no matter what you eat. If this describes you, consider talking to your doctor about ways to cut back or stop your alcohol use.

Islet transplantation, blood sugar and type 1 diabetes

New clinical trial results show that transplantation of pancreatic islets--cell clusters that contain insulin-producing cells--prevents severe, potentially life-threatening drops in blood sugar in people with type 1 diabetes. Researchers found that the treatment was effective for people who experienced episodes of severe hypoglycemia--low blood sugar levels that can lead to seizures, loss of consciousness and death--despite receiving expert care.

The Phase 3 trial was funded by the National Institute of Allergy and Infectious Diseases (NIAID) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), both part of the National Institutes of Health, and was conducted by the NIH-sponsored Clinical Islet Transplantation (CIT) Consortium. The investigators designed the study in consultation with the U.S. Food and Drug Administration to enable potential future licensure of the manufacture of purified human pancreatic islets. The results appear online today in Diabetes Care.

"The findings suggest that for people who continue to have life-altering severe hypoglycemia despite optimal medical management, islet transplantation offers a potentially lifesaving treatment that in the majority of cases eliminates severe hypoglycemic events while conferring excellent control of blood sugar," said NIAID Director Anthony S. Fauci, M.D.
