The causes of overactive bladder syndrome include neurogenic theory, myogenic theory, epithelial theory, and other theories.
1. Neurogenic theory: This theory suggests that the development of overactive bladder is related to neurological lesions, which include hypersensitivity of sensory nerve endings in the bladder, increased excitability of spinal reflexes, or lesions of the downward inhibitory pathways of the central nervous system, etc. The theory also suggests that the development of overactive bladder may be related to the development of a neurological disorder.
2. Myogenic theory: This theory suggests that the occurrence of overactive bladder is related to the increased excitability of the detrusor muscle cells themselves. Spontaneous contraction of the detrusor smooth muscle cells and enhanced impulse transmission between the cells can induce involuntary contraction of the detrusor muscle, resulting in overactive bladder.
3. Epithelial origin theory: This theory suggests that the occurrence of overactive bladder is related to changes in receptors or neurotransmitters released from the epithelium of the bladder mucosa.
4. Other theories: such as the bladder micromotor theory, the bladder-bowel-brain axis theory.
If you have overactive bladder, please consult a doctor promptly.
