What other disorders is nocturia linked to?

I'm in my thirties and have recently developed nocturia. I've never had any issues with it before. What other disorders could be linked to this sudden nocturia? Which medical issues should I get tested for?

Nocturia could be related to obstructive sleep apnea. Nocturia becomes more common as we age. As we get older, our bodies produce less of an anti-diuretic hormone that enables us to retain fluid. With decreased concentrations of this hormone, we produce more urine at night.

I am not certain what you mean when you say what "other disorders" is nocturia linked to. Nocturia is not exactly normal. Our renal blood flow is reduced at night to protect us from having to urinate. Many conditions are responsible for nocturia. These include such disorders as diabetes mellitus, prostate enlargement, over active bladder, medication effect and, of course, obstructive sleep apnea. When breathing stops, the heart, which depends on oxygen for energy, must slow down to conserve energy. Blood continues to flow into the heart. To prevent this slow pumping heart from failing, there must be a reduction in fluid volume. Therefore, the heart secretes a diuretic, which results in nocturia.
