Weakened Muscles
Just like other organs, the bladder is regulated by many muscle groups. These include the abdominal wall, sphincter, and the bladder muscles. When these components are affected and weakened, they would result in bladder spasms. There are many causes of weakened muscles in the bladder areas. Among these, nervous system disorders are the most common triggers. People with these conditions cannot send proper signals from the brain to control their muscles. As a result, the bladder cannot contract or tighten as you want. [2]
