Other conditions associated with CF include: CF-related diabetes caused by chronic damage to your pancreas, nasal polyps(small growths in your nose), CF-related liver disease, osteoporosis(thinning of your bones), constipation leading to bowel obstruction known as distal intestinal obstruction syndrome(DIOS), male infertility because the tube that carries sperm- the vas deferens becomes blocked, fertility problems in women because the cervix becomes blocked with thick mucus. These symptoms aren't always due to CF but if you have them you should visit your doctor for advice.
