People who have cystic fibrosis can have a hard time getting enough salt or water in their bodies. They need to drink extra fluids and eat salty foods to help replace the water and salt they lose through sweating.

If you do not have enough salt, your body cannot cool off very well, which may cause symptoms of weakness, fever, muscle cramps, stomach pain, and vomiting. It is important to drink extra fluids, especially when you are sweating. Sports drinks that contain electrolytes (such as sodium and potassium) are especially good to help replace lost salts.

Do not use salt tablets without talking to your doctor.
