According to a guide line, if you urinate more than 8 time during daytime, you are diagnosed with frequent urination. That is urinating about every one and a half hour. During night time, even if you urinate once, you are diagnosed with nocturia (night urination).
However, if you need to urinate because of drinking large amount of water, it is not regarded as frequent urination.
When it is cold, urinating frequently is caused by the stimulation of coldness.
Some of frequent urination are caused by brain disorders, but most of frequent urination is considered as being caused by aging.
Difference of bladder between people with frequent urination and people without frequent urination
People with frequent urination have a desire to urinate even if only small amount of urine is accumulated with aging (Fig. 1).
How to improve frequent urination
Bladder is a bag made of muscles. When urine goes into it, the bladder expands like a balloon and urine is accumulated. When a certain amount of urine is accumulated, the nerves around the bladder transmits a signal to the brain. The brain transmits a desire to urinate to the bladder and urination occurs.
However, aging makes the nerves around the bladder too sensitive and desire to urinate is caused by accumulation of small amount of urine. Therefore, frequent urination with aging is caused by the malfunction of the nerves around the bladder.
The nerves around the bladder controls not only the bladder but also the anus and the urinary tube, and they go down to the toes and control the movement of the muscles of the toes (Fig. 2).
The nerves run near the surface of the skin around the ankle, so massaging around the ankle can suppress the malfunction of the nerves (Fig. 3).
Massage to improve frequent Urination
Where to massage is 4 fingers above the inner ankle and beside the bone, where you feel tender when you press with your finger, which is an acupuncture point Spleen-6 (Fig. 4 and 5).
Press the point for about 1 minute with a little strong pressure. Do this massage 3 times a day, in the morning, at noon and in the evening.
A 52 years old woman needs to go to the bathroom for urination 23 times a day including an20 times during day and 3 times during night time. That means she has to go to the bathroom every 30 minutes to 1 hour during daytime and every 2 and half hour during night time.
In this experiment, she massages Spleen-6 for 1 minutes 3times a day after every meal for 7 days.
Day 1: 12 times
Day 2: 10 times
Day 3: 9 times
Day 4: 8 times
Day 5: 8 times
Day 6: 7 times
Before the experiment, she had a desire to urinate 47 minutes after drinking 500 ml of water, but after the experiment, it took 1 hour and 20 minutes.
Fig. 6 shows MRI image of her bladder before and after the experiment. It shows that her bladder became able to expand and accumulate large amount of urine before she had a desire to urinate (Before: 128 ml / After: 483 mil). That means, she became able to accumulate 4 times more urine before having a desire to urinate.
