What is Tea and toast syndrome?

Tea and toast syndrome is a form of malnutrition commonly experienced by elderly people who are unable to prepare meals and tend to themselves. Their diets often dwindle to tea and toast resulting in a deficiency of vitamins and other nutrients. The syndrome often manifests itself as hyponatremia, a low concentration of the electrolyte sodium in the bloodstream, due to the lack of salt in the diet. Hyponatremia can lead to various neurological problems ranging from headaches and a decreased ability to think, to seizures and coma in the most severe cases.
