生病

同事的先生患了肾病，说一工作就容易感觉疲劳。我八卦上前了解详情。
医生说，病发时间应该是在五年前开始。如果早一点发现而及时就诊，就不会像像今天这样的病情，棘手。
同事说，就算是一年前，根本就看不出来有什么症状，更甭说五年前了。
同事的老公还比我年轻，听说暂时不能工作要在家修养，自己心理难免也有几分同情。听说洗肾是很痛的。
同事拿了先生的身体检验报告还有医生诊病报告给我们看，其实我看不懂。我看了医生的报告上写着IgA nephropathy，医生的字体潦草，我大概猜测。
后来上了谷歌搜寻，还真有这种病嘞！

What is IgA nephropathy?
IgA nephropathy is a kidney disorder that occurs when IgA—a protein that helps us fight infections—settles in the kidneys. After many years, the IgA deposits may cause the kidneys to leak blood and sometimes protein in the urine.
Many people with IgA nephropathy leak blood in the urine, but this leakage does not mean they will have long-term problems. Others leak both blood and protein in the urine. If too much protein leaks into the urine, the hands and feet can swell. After 10 to 20 years with IgA nephropathy, the kidneys may show signs of damage. About 25 percent of adults with IgA nephropathy develop total kidney failure. Only 5 to 10 percent of children develop total kidney failure. Symptoms of kidney failure include swelling in the hands and feet, nausea, fatigue, headaches, and sleep problems. By the time these symptoms occur, total kidney failure is near. Total kidney failure means the kidney damage is permanent. People with kidney failure need dialysis or a kidney transplant.

那正是我同事先生的病况。
有什么是我们可以预测的，预测到的我们又会怎样预防，预防了又有多少巴仙会成功？
