Prenatal undernutrition is associated with low birth weight, coronary heart disease, type 2 diabetes, stroke, hypertension, cardiovascular disease risk, and depression. Muscle dysmorphia is characterized by appearance preoccupation that ones own body is too small, too skinny, insufficiently muscular, or insufficiently lean. Muscle dysmorphia affects mostly males. Purging disorder. Recurrent purging behavior to influence weight or shape in the absence of binge eating. It is more properly a disorder of elimination rather than eating disorder. Symptoms and long-term effects
Symptoms and complications vary according to the nature and severity of the eating disorder:
Associated physical symptoms of eating disorders include weakness, fatigue, sensitivity to cold, reduced beard growth in men, reduction in waking erections, reduced libido, weight loss and growth failure.Frequent vomiting, which may cause acid reflux or entry of acidic gastric material into the laryngoesophageal tract, can lead to unexplained hoarseness. As such, individuals who induce vomiting as part of their eating disorder, such as those with anorexia nervosa, binge eating-purging type or those with purging-type bulimia nervosa, are at risk for acid reflux.Polycystic ovary syndrome (PCOS) is the most common endocrine disorder to affect women. Though often associated with obesity it can occur in normal weight individuals. PCOS has been associated with binge eating and bulimic behavior.Other possible manifestations are dry lips, burning tongue, parotid gland swelling, and temporomandibular disorders.
The next recorded description occurs 3000 years later and is recorded by Vesalius, who described the appearance of "worm-like" movements of the heart in animals prior to death.The significance and clinical importance of these observations and descriptions possibly of ventricular fibrillation were not recognised until John Erichsen in 1842 described ventricular fibrillation following the ligation of a coronary artery (Erichsen JE 1842). Subsequent to this in 1850, fibrillation was described by Ludwig and Hoffa when they demonstrated the provocation of ventricular fibrillation in an animal by applying a "Faradic" (electrical) current to the heart.In 1874, Edmé Félix Alfred Vulpian coined the term mouvement fibrillaire, a term that he seems to have used to describe both atrial and ventricular fibrillation. John A. MacWilliam, a physiologist who had trained under Ludwig and who subsequently became Professor of Physiology at the University of Aberdeen, gave an accurate description of the arrhythmia in 1887. This definition still holds today, and is interesting in the fact that his studies and description predate the use of electrocardiography.
