              1. Failure to respond to insulin
                1. Don't eat too much carbohydrates
              2. Insulin
                1. Produced by the pancreas
                  1. Acts on the liver
                    1. Converts excess glucose to glycogen
                    2. Glucagon converts glycogen back to glucose
                    3. MINERAL/ION CONTENT

                                        1. ADH
                                          1. Hormone controls the amount of water taken back into the blood
                                            1. Produced by the pituitary gland
                                              1. Alcohol reduces ADH release
                                                1. Ecstasy increases ADH release

                                              1. 37 degrees
                                                1. Vasodilation
                                                  1. Increased sweat production
                                                    1. Widened blood vessels
                                                      1. Blood flow nearer skin surface
                                                      2. Vasoconstriction
                                                        1. Decreased sweat production
                                                          1. Closing down of blood vessels close to skin
                                                          2. Too low - hypothermia
