👉 Polycystina is a disease characterized by excessive accumulation of cysts in various organs, typically affecting the kidneys and urinary system. It's caused by an overproduction of hormones that are produced by the adrenal gland, leading to the formation of cysts on the kidneys, ureters, bladder, and other parts of the urinary tract. This condition can lead to symptoms such as frequent urination, excessive thirst, night sweats, and fatigue.
