When a person is in a state of tension, it is easy to stimulate sympathetic excitation, causing increased excitability of the urethral muscle, resulting in bladder contraction, which will produce the feeling of frequent urination. Generally, when the human body in a large number of water to make the bladder after the accumulation of urine to a certain degree, will stimulate the bladder to produce urinary response. However, when a person is in a state of stress, it is easy to stimulate sympathetic nerve excitation, leading to bladder contraction, thus producing the feeling of frequent urination. For example, a person is prone to frequent urination when he or she is in a stressful environment such as an exam or a lecture. In addition, the sympathetic nerves and skeletal muscles are excited when a person is nervous, which may also trigger autonomic dysfunction, and some patients may experience dizziness, headache, panic and shortness of breath, gastrointestinal discomfort and other symptoms. When patients suffer from prostatitis, diabetes and other chronic diseases may also trigger urinary frequency. It is recommended that patients keep their mood happy and relaxed, and learn to divert their attention when they are nervous, which can help reduce the symptoms. If the patient has frequent urination for a long period of time, accompanied by symptoms such as pain in urination, blood in the urine and pain, he should go to the hospital in time for examination and treatment.
