Regulation of digestion, diseases and Laboratory work 4

Digestive illnesses include inflammation of the stomach and intestinal lining (gastritis, enteritis), infectious diseases (dysentery, typhoid, cholera, hepatitis A) and infection with parasitic worms. They often spread through dirty hands, contaminated water, unwashed fruit and vegetables, undercooked meat and flies. Prevention: wash hands with soap before eating and after the toilet; drink clean or boiled water; wash fruit and vegetables well; cook meat thoroughly; keep food covered and do not eat expired food. Signs of food poisoning: stomach pain, nausea, vomiting, diarrhoea. Important: do not induce vomiting, and do not take antibiotics or other medicines on your own. Tell adults at once, take small sips of water and rest; if there is blood in the stool, vomiting does not stop, there is a high temperature, severe weakness or signs of dehydration – call 103 or a doctor. Antibiotics are prescribed only by a doctor. Alcohol and smoking harm the stomach, intestine and liver and are completely unsuitable for teenagers. Dairy products, vegetables and fruit are good for the gut flora.
