Decreased Bladder Elasticity. One of the reasons for nocturia or overactive bladder in older people is that the older one becomes, the bladder loses its elasticity resulting in nocturia in older individuals.
Hormonal Causes. Our body makes a hormone during night, which reduces the function of kidney while we are sleeping. So we normally make less urine during night time. However, as we grow older less amount of this hormone is produced and this in turn may lead to nocturia as we get older.
Enlarged Prostate Glands. Prostate glands in men usually get enlarged as they grow old. This in turn restricts the bladder outlet and thus not the entire amount of urine from the bladder is passed out. This means the bladder gets filled quickly again and thus may make the person go for frequent urination. It is known that about 60% to 80% of men above 80 years of age have an enlarged prostate gland causing nocturia in them.
Less Efficient Circulatory System. A less efficient circulatory system during older age may also be a reason for nocturia in older people. The kidneys filter our blood, as it passes through them and then collect the waste products along with extra fluids from around our body. Then they form the urine from the waste products and excess fluid and pass it to the bladder. However as we grow old, the circulatory system has a reduced function or becomes less efficient. This means, some amount of fluid are left behind in the body tissues, especially in the ankles in the lower legs. As we lie down it becomes easier for the circulatory system to function. Thus, the fluids from ankles pass in to the bloodstream and reach the kidney and then again pass to the bladder as urine. This means, your bladder fills quickly as we sleep. Thus, this is why nocturia is common in older people.
