飲食和生活方式因素不會導(dǎo)致1型糖尿病

Type 1 diabetes is caused by an autoimmune reaction (meaning the body attacks itself by mistake) that destroys the cells in the pancreas that make insulin, Katherine Araque, M.D., director of endocrinology of the Pacific Neuroscience Institute at Providence Saint John's Health Center in Santa Monica, Calif., tells Health. What actually causes that autoimmune reaction in the first place isn't completely known at this time.

1型糖尿病是由自身免疫反應(yīng)(也就是說身體在誤傷自己)引起的，該反應(yīng)會破壞胰腺中制造胰島素的細(xì)胞，加利福尼亞州圣莫尼卡市普羅維登斯圣約翰健康中心太平洋神經(jīng)科學(xué)研究院的分泌科主任凱瑟琳·阿拉克(Katherine Araque)醫(yī)學(xué)博士對《健康》雜志說道。目前尚不完全了解導(dǎo)致自身免疫反應(yīng)的真正原因。

This process can go on for months or even years before someone develops symptoms, the CDC says. Unlike type 2 diabetes, diet and lifestyle factors don't cause type 1 diabetes. But beyond that, there are some factors that put someone at a greater risk of developing type 1 diabetes:

美疾控中心表示，在癥狀顯露之前，這一過程可能會持續(xù)數(shù)月甚至數(shù)年。與2型糖尿病不同，飲食和生活方式因素不會導(dǎo)致1型糖尿病。但除此之外，其它一些因素卻與1型糖尿病患病風(fēng)險息息相關(guān)：

A family history of the disease

1型糖尿病家族史

Having a parent, brother, or sister with type 1 diabetes, raises a person's risk of also developing the disease—but it's not a given. "There certainly is an inherited tendency but that alone is not sufficient," Dr. Dungan says, noting that plenty of people have the disease with no immediate relatives who also have it. "It's not like type 2 diabetes, where almost everyone has a close relative with it," she says.

父母/兄弟/姐妹患有1型糖尿病會增加一個人的患病風(fēng)險——但這并不是絕對的。“遺傳趨勢當(dāng)然存在，但僅有遺傳趨勢卻不足以致病，”鄧根醫(yī)生說道，并指出，很多1型糖尿病患者并沒有直系親屬也患有這一疾病。“這與2型糖尿病不同，大多數(shù)患者的近親也患有這一疾病，”她說道。

A younger age

年齡較小

Type 1 diabetes usually starts when someone is a child or young adult but, the CDC points out, you can technically develop the disease at any age. "It's not that there's an absence of risk as one gets older; It's just that the incidence of type 2 diabetes goes up with age," Dr. Dungan says.

兒童或青年人更易患1型糖尿病，美疾控中心指出，但實際上，任何年齡段都有可能患上該疾病。“年齡大的人也存在患病風(fēng)險;而2型糖尿病的患病風(fēng)險是隨著年齡增加而增加的，”鄧根醫(yī)生說道。

Environmental factors

環(huán)境因素

It's possible that environmental factors might be involved in the development of type 1 diabetes, like patients having a virus, like enterovirus, or being exposed to certain things before they develop the disease, but it's more of a theory at this point. "It hasn't really been well understood," Dr. Dungan says.

1型糖尿病的發(fā)生可能與環(huán)境因素有關(guān)，例如病毒(如腸病毒)患者或患者在患病前暴露于特定環(huán)境中，但目前這只停留在理論階段。鄧根醫(yī)生說：“我們尚未完全了解。”

Given that the cause of type 1 diabetes isn't completely understood, scientists haven't figured out a set way to prevent the disease. "There are multiple ongoing trials right now to try to figure out how to prevent type 1 diabetes, but we haven't extrapolated anything yet," Dr. Araque says.

鑒于1型糖尿病的病因尚不明確，科學(xué)家還未找到預(yù)防這一疾病的方法。阿拉克醫(yī)生說道：“目前正在進行多項試驗以找出預(yù)防1型糖尿病的方法，但尚未有突破性進展。”
