Chloride is an electrolyte that works together with sodium to keep the body’s fluid balance and acid–base balance steady. Most of it comes from salt in food. The level is read together with sodium and potassium.
Salt intake and hydration have the biggest effect. Vomiting or diarrhoea, for example during a stomach bug, heavy sweating and some medicines such as diuretics can shift the level for a while.
Foods that help
Enough water through the day, vegetables and fruit, and a moderate amount of salt from ordinary food.
Foods to limit
A lot of salty, processed food and long periods of drinking too little.
