Is the twin status associated with an increased risk of type 2 diabetes?

Conclusions: Twin status per se is associated with abdominal obesity, insulin resistance, and increased prevalence of type 2 diabetes in elderly twins. The data support a quantitatively significant impact of the fetal environment as opposed to genetics on risk of type 2 diabetes.

Are twins more likely to have diabetes?

Twins of people diagnosed with type 1 diabetes are much more likely to develop the condition within three years than other siblings, according to the results of a recent study. This was true of both identical and non-identical twins who were already known to be at high risk of developing type 1 diabetes.

Why would one twin have type 2 diabetes?

“This means that the twins with diabetes were not able to process fat as well, which leads to raised levels of fat in the blood and uptake of fat by other organs such as the muscles, liver and pancreas. This causes insulin resistance, leading to type-2 diabetes,” explained researcher Emma Nilsson.

What is the main risk factor for type 2 diabetes?

Being overweight is a primary risk factor for type 2 diabetes. This is because the more fatty tissue you have, the more resistant your cells become to insulin. If your body stores fat primarily in your abdomen, your risk of type 2 diabetes is greater than if your body stores fat elsewhere.

What is the risk for becoming diabetic if your identical twin is diabetic?

Identical twins have identical genes. Yet when one twin has type 1 diabetes, the other gets the disease, at most, only half the time. When one twin has type 2 diabetes, the other’s risk is three in four at most.

Can only one identical twin have diabetes?

OBJECTIVE—Monozygotic twins are usually discordant (only one twin affected) for type 1 diabetes. Discordance for disease between such twins implies a role for nongenetically determined factors but could also be influenced by a decreased load of diabetes susceptibility genes.

Are identical twins 100% the same?

Identical twins form from the same egg and get the same genetic material from their parents — but that doesn’t mean they’re genetically identical by the time they’re born.

What determines identical twins?

Identical twins come from one fertilized egg called a zygote. The zygote, which usually develops into one child, instead grows and splits early in development to form two embryos. Because the twins come from one egg and one sperm, they have exactly the same DNA and are, therefore, identical twins.

How is type 2 diabetes inherited?

Type 2 diabetes does not have a clear pattern of inheritance, although many affected individuals have at least one close family member, such as a parent or sibling, with the disease. The risk of developing type 2 diabetes increases with the number of affected family members.

Why is type 2 diabetes increasing in the US?

Obesity is a major risk factor for developing type 2 diabetes, which is the type of diabetes affecting 90–95% of Americans. The increasing incidence of diabetes is in line with the increasing prevalence of obesity in the United States.

Which is most likely responsible for the recent increase in type 2 diabetes in the population?

Obesity is the single most important factor responsible for the marked increase in both the incidence and prevalence of type 2 diabetes over the last 20 years (3a). Weight gain (109a) and physical inactivity (110a,111a) cause insulin resistance.

Why is age a risk factor for type 2 diabetes?

As you age, you’re more likely to have multiple medical conditions, including high blood pressure and high cholesterol. That can make it harder for you to keep your diabetes under control.

Who is most at risk for type 1 diabetes?

In the United States, Caucasians seem to be more susceptible to type 1 than African-Americans and Hispanic-Americans. Chinese people have a lower risk of developing type 1, as do people in South America. Geography: It seems that people who live in northern climates are at a higher risk for developing type 1 diabetes.

What is the main cause of insulin resistance?

Obesity (being significantly overweight and belly fat), an inactive lifestyle, and a diet high in carbohydrates are the primary causes of insulin resistance.

Is there such thing as mirror twins?

The term mirror twin is used to describe a type of identical, or monozygotic, twin pairing in which the twins are matched as if they’re looking into a mirror — with defining characteristics like birthmarks, dominant hands, or other features on opposite sides.
