T1D Facts and Myths


Myth: T1D is caused by eating too much sugar or being obese.
Fact: Sugar intake and obesity have nothing to do with the onset of T1D. While we still do not know exactly what triggers the onset of T1D, scientists believe that both genetic and environmental factors are involved.

Myth: Only children are diagnosed with T1D.
Fact: While children are the age group most frequently associated with T1D, formerly called “juvenile diabetes,” it is regularly diagnosed in teens, young adults and adults. You can develop T1D at any age.

Myth: You can cure T1D by taking insulin.
Fact: Taking insulin keeps people with T1D alive, but it is not a cure.

Myth: People with diabetes can’t or shouldn’t eat sugar or sweets.
Fact: While limiting sugar intake can be a part of a healthy diet, people with T1D can work sugars and sweets into their diets just like a person without T1D. Sometimes sugar is necessary. If a person’s blood-sugar level drops too much, sugar, often in the form of juice or glucose tables, is required to raise it and correct hypoglycemia (low blood sugar).

Myth: Women with T1D shouldn’t get pregnant.
Fact: Women with T1D regularly have healthy pregnancies and deliver healthy babies with planning and support.

Myth: T1D is contagious.
Fact: T1D is not contagious. T1D does not spread from person to person, but families with a history of autoimmune diseases may have more than one family member with T1D.

Myth: People with T1D will go blind.
Fact: While some people with T1D have complications, many live with T1D for decades without any complications. Every person is different and some are more genetically predisposed to complications, but optimal control of blood sugar is proven to significantly lower the risk of complications.

Myth: You can cure T1D with diet and exercise.
Fact: There is no cure for T1D. Healthy eating and exercise can help people with T1D maintain better blood-glucose control, but there is no cure.
