The search for what triggers type 1 diabetes

“Everyone’s like, ‘Wow, how in the world does (my sister) not have it?’ ” said Payne, 23, who once played forward on Stanford’s soccer team, like her sister. Low blood sugar in pregnancy “They can’t really fathom it.”

Though experts agree that genetics influence who gets type 1 diabetes, Payne’s story suggests that something other than genes must also be at play. Low blood sugar symptoms without diabetes And some researchers are focusing in on one family of viruses in particular.

A new study from Finland joins decades of research suggesting that enteroviruses, which include over 100 individual virus types, may play a key role in triggering type 1 diabetes, which has no cure.


In autoimmune diseases such as type 1 diabetes, the immune system backfires. Fasting blood sugar test can you drink water Antibodies, small proteins that attack unwelcome guests like bacteria and viruses, in rare cases attack one’s own cells. Fasting blood sugar for diabetic In Payne’s case, those happen to be the insulin-producing cells of her pancreas.

Doctors are not sure whether and how viruses trigger type 1 diabetes, but many point to a special property of enteroviruses: These viruses have a “tropism,” or attraction, to those same insulin-producing cells in the pancreas, according to Dr. Blood glucose levels normal range Heikki Hyoty, who led the new study at the University of Tampere in Finland. Glucose in blood test Hyöty and others believe the virus establishes a chronic infection in these cells, possibly leading to inflammation and self-attacking antibodies, known as autoantibodies. Blood sugar range normal However, it is far from a smoking gun.

“The association is clear, but the causation is not,” said Dr. What causes high blood sugar levels in non diabetics Mary Pat Gallagher, a pediatric endocrinologist at NYU Langone Medical Center who was not involved in the study. Blood sugar low symptoms “It may just be one piece of puzzle.”

The Finland study is the largest of its kind, collecting stool samples from more than 400 young children to look for enteroviruses, which largely affect the gut. Gestational diabetes blood sugar levels The children who tested positive for multiple autoantibodies were more likely to have been infected with an enterovirus than children who had a similar genetic risk for diabetes. Blood sugar levels gestational diabetes Only 75 percent of children with autoantibodies went on to develop diabetes symptoms by the end of 2015, though Hyoty said that figure is likely to increase over time.

Though many studies have shown a similar link, several others have shown no link at all. Normal fasting blood sugar In the United States, a number of ongoing studies are looking for similar answers. Symptoms of elevated blood sugar One, known as “The Environmental Determinants of Diabetes in the Young,” or TEDDY, is also trying to identify environmental causes of type 1 diabetes — including the possible role of viruses, diet, socioeconomic factors and toxic substances.

Enteroviruses cause between 10 and 15 million infections per year, often during summer and fall, according to the Centers for Disease Control and Prevention. Blood glucose levels fasting They can spread through any number of ways: shaking hands, drinking contaminated water, changing a diaper. Symptoms of blood sugar drop These infections rarely cause serious illness, and many people do not feel sick at all. High blood glucose But for some with weak immune systems, such as infants, there can infrequently be serious complications.

Though enteroviruses can be avoided by handwashing and avoiding contact with sick people, Hyoty is focusing on vaccines as a possible way to prevent type 1 diabetes. High blood glucose levels So far, vaccine prototypes have been developed only in mice, he said.

“That would be great if it were possible,” Gallagher said. What is a fasting blood sugar “The problem is that there are so many strains of enterovirus,” and no one strain has been identified as more culpable than the others.

The Finland study received partial funding from Sanofi Pasteur and Vactech Ltd., both of which have a stake in enterovirus vaccine research and development. What should my blood sugar be 1 hour after eating Both Hyoty and a coauthor of the study are minor shareholders of Vactech and serve on its board.

The connection between viruses and autoimmune diseases is hardly a new one. Normal blood sugar levels after eating for non diabetics Last year, the Zika virus made headlines when it seemed to correlate with an uptick in Guillain-Barre syndrome, a rare form of autoimmune paralysis that rises from the feet. Gestational diabetes blood sugar levels chart Still, the vast majority of people infected with Zika, like the majority of people infected with enteroviruses, do not develop autoimmune disease.

According to Hyoty’s calculations, genetics may be responsible for “half or more” of type 1 diabetes cases — though relatively few people who carry the genetic markers ultimately develop diabetes.

But genetics and the environmental may differ across countries and ethnic groups, Gallagher said. Average blood sugar calculated from the hba1c So data from Finland, which has some of the highest rates of type 1 diabetes in the world, may not be generalizable to countries like the United States, she said.

Between meal planning, finger-pricking, measuring insulin and accounting for exercise, Gallagher says, her young diabetes patients and their families may have a hard time adjusting to a new lifestyle.

Payne is now studying to be a doctor at Vanderbilt School of Medicine, along with her sister. Blood sugar drop She does not remember being sick as a kid, and neither she nor her doctors have been able to pinpoint a reason for why the siblings share 23 sets of chromosomes but only one has diabetes.

Currently on her surgery rotation, a strong interest of hers, she is faced with the reality of operating on patients for hours, wearing a surgical mask and unable to eat glucose tablets while scrubbed in. Normal blood sugar level non diabetic Though her diagnosis may make medical school more difficult in some ways, she said, it does have an upside.
