Kidney-related illness increases day by day. If you know anyone suffering from kidney ailments you can suggest to them this saint- Saint Virgin and martyr Marina (Margarita) of Antioch in Pisidia. She was born in 255 and is recognized as the patron saint of kidney-related illness and the patron of nephrology.
From the beginning of the 13th century she has healed, in particular, patients suffering from nephropathies, pregnant women having difficult childbirth, barren women, and sickly children. She protects the patients from every side effect and complication. Saint Marina is portrayed in hagiography as a victor, defeating the dragon Satan, holding a hammer or a cross, and wearing a belt around her back in the area of her kidneys.
According to writers, artists, and sculptors, the belt is the perceivable means of Saint Marina for the miraculous recovery from and healing of kidney diseases. Therefore, those who are suffering from kidney disease and pregnant women put their belts upon the relics for the blessing and then wore them. From the Middle Ages and Renaissance and up to the contemporary period Saint Marina (Margarita) has been considered patron saint of kidney patients. Justifiably she is recognized by the modern medical world as the protector of nephrology.
