我们将揭示11种引起疲劳的健康状况。

1 iron deficiency anaemia

Iron deficiency anaemia is one of the most common medical reasons for feeling constantly run down. Affecting around one in 20 men and post-menopausal women, it’s more common in pregnant women and those who are still having periods, especially if they are heavy.

缺铁性贫血是最常见的感到持续无力的医学原因之一。大约每20个男人和更年期妇女中有一个会受到影响，在孕妇和待孕的尤其是那些偏胖的人中更常见。

It can be diagnosed with a blood test. Eating iron-rich foods, such as red meat, shellfish and iron-fortified cereals, or taking iron supplements can help.

这种疾病能被血样测试诊断。吃富含铁的食物，例如熟肉，水生有壳动物和提高铁营养价值的谷物，或提供铁有助于减少疲劳。

2 chronic fatiguesyndrome

2 长期疲劳症状

If your fatigue has lasted for six months or more and is so severe that you can’t manage daily tasks, chronic fatiguesyndrome (also known as myalgic encephalopathy or ME) could be to blame. Along with persistent, unexplained exhaustion, other symptoms include a sore throat, muscle or joint pain and headaches.

如果你的疲劳感长达六个月或更多，并且它是如此严重以至于你不能成功完成日常任务，长期的疲劳症状（也被了解为慢性疲劳症）应当视为罪魁祸首。伴随着持续的状况，无法解释的筋疲力尽，其它症状包括喉咙痛，肌肉或关节痛和头痛。

There is no test for ME but there are clear guidelines to help doctors diagnose it. While there is no cure or medication, lifestyle changes may help.

对于慢性疲劳症无法测试，但清晰的条目有助于医生诊断它。然而没有药方或药，生活方式的改变或许会起作用。

3 gluten

3 谷蛋白

This is a type of food intolerance where the body wrongly believes gluten is attacking it, resulting in damage to the lining of the gut. For coeliacs, eating even the smallest crumb of gluten (found in things like bread, cakes and pasta) can cause tiredness along with bloating, diarrhoea, nausea, muscle pain and headaches.

这是一种身体完全不能接受的食物类型，身体错误的认为是谷蛋白在袭击它，导致肠道线的损坏。对于腹腔，吃甚至是最少量的谷蛋白碎屑（在食物中能够发现，例如面包，蛋糕和意大利面）能导致疲劳伴随着肿胀，腹泻，作呕，肌肉痛和头痛。

It can be diagnosed with a blood test. There is no medication - the only treatment is to follow a strict gluten-free diet for life.

它能被血样测试诊断。无需药物——唯一的治疗方式是在生活中遵循严格的无谷蛋白的饮食。

4 Sleep apnoea

4 睡眠呼吸暂停

Sleep apnoea is a condition where a person stops breathing between loud snores. These pauses in breathing happen when the airways narrow or close completely, depriving the lungs of oxygen. When the brain detects dangerously low levels of oxygen, it automatically wakes the sufferer, so they can return to normal breathing.

睡眠呼吸暂停指人在很大的鼾声中停止呼吸的状况。呼吸暂停的情况往往在气流狭窄或完全关闭的情况下发生，剥夺肺部的氧气，当大脑发现氧气量处于危险的低水平的时候，会自动地叫醒睡着的人，因此它们会返回正常的呼吸状态。

Most common in overweight, middle aged men, those with the condition are at increased risk of stroke, cardiovascular disease and hypertension. For many sufferers, the only sign is feeling exhausted the next day. Breathing machines worn at night, plus lifestyle changes, can help.

最常见的体重偏胖见于中年男子，伴随着中风，心血管疾病和高血压增加的危险。对于许多患者，唯一的标志是第二天感到筋疲力竭。晚上戴上氧气罩，加上改变生活方式有助于缓解这种状况。

It’s most common in women and you’re more at risk the older you are. Your doctor can diagnose the condition with a blood test. It can be treated with daily hormone tablets.

这种状况在女人中最常见，你的年龄越大你患病的风险越高。医生会通过血样测试诊断你的情况。每天吃荷尔蒙药片能治疗这种疾病。
