mindmap root((HYP/HYPO)) hypochondriac A person overly concerned with his or her own health who often suffers from delusions of physical disease.
🌱Hercule Poirot, the detective hero of the Agatha Christie mysteries, is a notorious hypochondriac, always trying to protect himself from drafts. 🌳One disease a hypochondriac really does suffer from is hypochondria, the anxiety and depression that come from worrying too much about one's own health. Even though it's easy to joke about hypochondriacs, hypochondria is no joking matter for the sufferer. Somewhat surprisingly, the second part of hypochondria derives from chondros, the Greek word for "cartilage." The cartilage in question is that of the sternum, or breastbone. From ancient times, doctors believed that certain internal organs or regions were the seat of various diseases, both physical and mental, and the area under the breastbone was thought to be the source of hypochondria. hypoglycemia Abnormal decrease of sugar in the blood.
🌱She had been controlling her hypoglycemia through diet and vitamins, but she now realized she needed to add daily exercise as well. 🌳The root glyk- means "sweet" in Greek, so glyc shows up in the names of various terms referring to a sugar as a chemical ingredient, such as glycerine and monoglyceride. People with diabetes have difficulty controlling the sugar in their blood. Too little can be dangerous; its early symptoms may be as minor as nervousness, shaking, and sweating, but it can lead to seizures and unconsciousness. Luckily, it can be taken care of easily by eating or drinking something high in carbohydrates. Its opposite, hyperglycemia （See HYPER,） is the main symptom of diabetes, and usually requires an injection of insulin, which the sufferer usually gives himself. Today many people—though not doctors—use hypoglycemia to mean a completely different condition, with some of the same milder symptoms, that doesn't involve low blood sugar. hypothermia Subnormal temperature of the body.
🌱By the time rescuers were able to pull the boy from the pond's icy waters, hypothermia had reached a life-threatening stage. 🌳Hypothermia, which usually results from submersion in icy water or prolonged exposure to cold, may constitute a grave medical emergency. It begins to be a concern when body temperature dips below 95°F, and the pulse, breathing, and blood pressure start to decline. Below 90°, the point at which the normal reaction of shivering ceases, emergency treatment is called for. hypothetical 1、 Involving an assumption made for the sake of argument or for further study or investigation.
2、 Imagined for purposes of example.
🌱The candidate refused to say what she would do if faced with a hypothetical military crisis. 🌳The noun hypothesis comes straight from the Greek word meaning "foundation" or "base"—that is something "put under" something else. So a hypothesis is something you assume to be true in order that you can use it as the base or basis for a line of reasoning—and any such assumption can be called hypothetical. So, for example, the theory that the dinosaurs became extinct because of a giant meteor that struck the earth near the Yucatán Peninsula involves the hypothesis that such a collision would have had such terrible effects on the earth's climate that the great reptiles would have been doomed. Once a hypothesis has been thoroughly studied and researched without being proved wrong, it generally comes to be called a theory instead.
