Bulimia nervosa and Food Poisoning

Bulimia nervosa

 Like anorexia, bulimia is an eating disorder found most commonly among younger women, often those who have had anorexia. Bulimics crave food but fear becoming fat. They indulge in binge eating by consuming vast amounts of food and then induce vomiting and use laxatives. This constant bingeing and vomiting can cause severe medical problems. Sufferers from bulimia require the same medical care as anorexics.

 Food poisoning


This refers to illnesses caused by eating food contaminated by certain micro organisms or the toxins, they produce. Worldwide, the incidence of food poisoning is on the increase. This is probably due to the growing use of convenience foods, such as cook chill meals, and the consumption of fast foods, which are easily subject to contamination by the people who make and serve them. Spores in raw rice, chicken beef, water or milk contaminated faeces are caused by Bacillus cerus and Campylobacter fetus. Botulism and Clostridium Perfinges are through food contaminated with bacterial toxin. Meat or vegetables contaminated by faeces. Amoebic dysentery can caused by food or water contaminated by faeces. Norwalk virus can infect through contaminated shell fishes and the rotavirus can introduced to our system by contaminated water or food. Undercooked poultry or egg can cause Salmonella. Food that contaminated by contact with wounds are the reason for the Staphylococcus.
