When the weather gets cold, people with frequent urination increase. But there are a lot of cases that heart diseases and blood vessel diseases are hidden behind frequent urination. So it is important to know the characteristics of your frequent urination.
Overactive bladder (OAB)
Because the nerves of the bladder become sensitive, frequent, sudden urges to urinate are caused even if urine is not accumulated.
The amount of urine at night is more than during daytime
Overactive bladder is the disease that the amount of urine at night is less than during daytime.
The diseases that the amount of urine at night is more than during daytime are heart diseases, sleep apnea syndrome, lifestyle related diseases such as diabetes and others.
Hyperparathyroidism is a disorder of the four parathyroid glands caused by the development of a benign tumor or others. These glands are about the size of a grain of rice and are located in your neck. The parathyroid glands produce parathyroid hormone, which helps maintain an appropriate balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning. the development of a tumor causes excess secretion of parathyroid hormone, causing abnormal activity of organs in whole body.
The kidney and muscles are easily affected by hyperparathyroidism.
If the kidney which regulates the amount of urine is affected, urine is produced too much.
If a pelvic floor muscle which supports the bladder is affected, frequent urination is caused by the decline of the function of the muscle.
Even if the test results of creatinine, calcium and blood pressure are within the range, they are a little bit high.
Swelling of legs and night urination
Water coming from swelling of legs leads to night urination.
People whose legs are obviously swollen have about 200-300 cc of water in one leg, more than 400 cc (2 glasses) of water for both legs.
The accumulated water in the legs comes back to the blood stream when lying down at night and the amount of water in the blood increases. The body tries to produce more urine to discharge the excess water, causing night urination.
Check the swelling of legs
When you press the inside of the shin with your finger, if the finger print stays there or a dimple doesn’t disappear, you have swelling of the leg and tend to have night urination (Fig. 1).
How to improve night urination by solving swelling of legs
The method is soaking in a bath tub.
The effect of water pressure and heat of warm water brings the water stored in the legs back to the blood. But it takes about 3-4 hours that the water returned to the blood becomes urine.
So it is recommended to take a bath 4 hours before going to bed.
If taking a bath 4 hours before going to bed is difficult, it is also recommended to massage legs, wear elastic stockings and lie down lifting legs up 4 hours before going to bed (Fig. 2).
