Salt and iodine deficiency in Switzerland

In Switzerland, a 2014 study revealed a worrying level of deficiency among the population: 2% of men but especially 14% of women are affected. Partly to blame are campaigns urging people to eat less salt to avoid problems linked to cardiovascular disease. Severe iodine deficiency leads to hypothyroidism, which can cause symptoms such as extreme fatigue and digestive problems like constipation.
