Urinary tract infections

Obstructive sleep apnea

This is a serious sleep condition. Obstructive sleep apnea is one type of sleep apnea and it occurs when muscles in your throat relax irregularly and obstruct air passages while you are sleeping. This obstruction lowers oxygen level in your blood and increases accumulation of carbon dioxide. Your brain notices this disrupted breathing and awakens you shortly from sleep so that you open the airways. This occurs shortly and you may not know that you had it. You may wake up with a short breath that rectifies itself faster after deep breaths.7

This pattern can recur about 30 times in an hour through the night. This disrupts your sleep pattern and therefore you are not able to sleep properly. You are more likely to feel sleep during the day and this affects negatively your daily activities.1, 4

Neurological disorders

Conditions that affect your nervous system can also cause nocturia including multiple sclerosis and Parkinson’s disease. Multiple sclerosis occurs when the immune system attacks the myelin sheath that protects nerve fibers. This disrupts communication between the brain and the rest of the body.

Edema occurs when a blood vessel in your body starts to leak and release fluids in the surrounding tissues which cause the tissue to swell. Edema can be caused by infections, other diseases such as heart disease and liver diseases and any condition that disrupts the balance of vital substances in your blood.7
