Cystitis is an inflammation of the bladder. It mainly affects women, and is usually caused by bacteria that enter the urethra and reach the bladder.
If you get cystitis, you should drink plenty of water to help flush out the germs.
You should also consult a doctor, who may prescribe antibiotics as well as plant-based supplements like bearberry or cranberry for their diuretic and antiseptic properties. To wash intimate areas, you should use a cleansing product that soothes irritations. If symptoms persist, consult your doctor.
