Cold nocturia is a disease or normal?

The weather is cooling, increased frequency of urination at night to get up a few friends, then nocturia is normal or disease? If confined to urine frequently at night, then we should look at the following two indicators.
Indicator one: with dysuria or urethritis
If accompanied by dysuria, there may be cystitis, prostatitis, urethritis caused.
Urethritis is a common disease, refers to inflammation of the urethral mucosa, female predilection. Clinically divided into acute and chronic, non-specific urethritis and gonococcal urethritis, the latter two similar clinical manifestations, must be identified based on history and bacteriology. Mostly caused by bacteria invade the urethra retrograde.

Two indicators: no dyspnea or edema, chronic nephritis
If there is no difficulty urinating, but accompanied by shortness of breath or swelling, then there may be congestive heart failure, and if not, it is likely that chronic nephritis. Referred to as chronic glomerulonephritis chronic nephritis, mean proteinuria, hematuria, hypertension, edema of the basic clinical manifestations, onset in different ways, protracted illness, slow disease progression, may have varying degrees of renal dysfunction, with a kidney deterioration tendency and will eventually develop chronic renal failure, a group of glomerular disease.
Chronic nephritis can occur at any age, but mainly young adult male common. Most of the slow onset, insidious. Diversity of clinical manifestations, proteinuria, hematuria, hypertension, edema its basic clinical manifestations, may have varying degrees of renal dysfunction, the condition light weight, persistent, progressive development of chronic renal failure. Laboratory tests mostly mild urinary abnormalities, urinary protein often 1 ~ 3g / d, urine sediment examination of red blood cells can be increased, visible tube. Blood pressure may be normal or slightly elevated. Normal or mildly impaired renal function (creatinine clearance rate or mild azotemia), this situation for several years, even decades, progressive deterioration of renal function and the corresponding clinical manifestations (such as anemia occurs, blood pressure increased and so on) into uremia.
