Frequent urination is what is known as frequent urination. The cause of frequent urination is relatively common, the most common being urinary tract infection, in which pathogenic bacteria stimulate the bladder and urethral mucosa, leading to its unstable contraction and frequent urination. It is also usually combined with symptoms such as urgency to urinate, painful urination, and chills and fever. Urinary tract infections are generally anti-pathogenic and can be treated with antibiotics against infection, while oral Chinese medicines such as Shuang Shi Tong Lian can be taken to relieve symptoms. Frequent urination can also be seen in overactive bladder syndrome, which is an unstable contraction of the bladder muscle and repeated contractions leading to frequent bladder urge to urinate. M-blockers such as solifenacin and tolterodine can be taken orally to inhibit bladder contraction and improve the symptoms of frequent urination.
