You are fatigued in the morning as your rise: you feel depressed and anxious without reason. You feel too chilly or too warm, too hungry or not enough. You sleep poorly. Often you have muscular cramps, fluttering eyelids, tingling, contractions: all these indicate neuromuscular overstimulation one of the most evident signs of spasmophilia, which is also sometimes called chronic tetany. But these are not the only symptoms: from headaches/ dizziness, a feeling of blurred vision, to the visceral symptoms which conern the digestive, respiratory, vascular systems, as well as the genital sphere, the range is vast and often misleading. Certain subjects have several symptoms, others only a few. However it is important to detect an unrecognized spasmophilia - often by the doctors themselves - and to lead patients out of inextricable pathological situations. Spasmophilia is a metabolical disease which can suddenly become worse under the impact of a trigger factor such as stress, mourning, divorce, professional worries, etc. It is not an imaginary disease nor a mental disease. It is diagnosed with precision, and treated effectively. Certain rules of food hygiene, certain precautions facilitate the prevention of the most disabling decompensations and the most anxiety provoking. This book, designed for the general public, concerns itself for the first time with this misunderstood and poorly known disease which affects so many people in the world.
