Among college students who do not even have an eating disorder, 26% of those merely at risk for eating disorders may abuse laxatives for weight loss purposes.9 In fact, patients with eating disorders, particularly those with bulimia nervosa and binge-purge anorexia nervosa, are likely to abuse laxatives. Purging may lead to excess alkalinity of the blood, potassium deficiency leading to atrial and ventricular arrhythmias and sudden cardiac death, aggravated hypotension with orthostatic blood pressure changes, gastric distention and even rupture, esophagitis and esophageal tears, loss of dental enamel and tooth breakage, aspiration of gastric contents leading to aspiration pneumonia and choking death, and chronic exposure of the esophagus to gastric acid leading to Barren's esophagus an...
Fatigue during hot-weather exercise is caused by lack of water, salt, sugar or calories. Of the four, exercisers are most ignorant of their sodium needs. A study from the University of Otago in New Zealand shows that taking a salty drink prior to competition can help an athlete to exercise longer and harder. Athletes who took the salty drink had larger blood volumes and greater endurance. Salt makes you thirsty earlier so you drink more, and salt in your body holds water so you have more water available to meet your needs. In 1942, James Gamble of Harvard Medical School was hired to establish guidelines for soldiers fighting in the hot climate of the South Pacific. He found that the only mineral needed for exercise in hot weather is sodium, found in common table salt. His research still...
WASHINGTON - The Tennessee cotton crop that agriculture officials had hoped would weather the drought is showing signs of stress and potassium deficiency, and corn farmers are being advised to adjust their combines to harvest smaller ears on weak stalks. The continued extreme heat and rainless skies are taking their toll on all Mid-South agriculture except crops in bottomland near streams, Jackson, Tenn.-based University of Tennessee agronomist Chris Main said Thursday.
DEAR DR. DONOHUE: I could play tennis from sunrise to sunset if it weren't for cramps in my calves. I don't get them every day, but I get them enough that they're a major nuisance. I'm in good shape and have been athletic my whole life. I am 43. What causes them? Is it the heat? How do I prevent them? - R.B. ANSWER: A cramp is a painful, prolonged, involuntary muscle contraction. The cause is a matter of debate. Some say it's dehydration. Others claim it's a deficiency of sodium, potassium, magnesium or calcium. They might come on with muscle fatigue. Being in good shape ought to prevent muscle cramps, but it doesn't. In Ironman contests during which contestants swim for 2.5 miles, ride a bike for 112 miles and run 26 miles, more than 6 percent of the participants have to seek medical h...
DEAR DR. DONOHUE: My husband is 74 and has vascular disease in his legs due to 60 years of smoking and sitting for 30 years driving a truck. He takes medicine for this. However, he has leg cramps and jerking, and they are getting worse. He gets relief only by sitting up and sleeping in a recliner. He isn't resting, and neither am I. I rub his legs, and that helps, but I can't do it all night. Can you recommend anything? - M.C. ANSWER: Cramps are sustained, painful contractions of muscles. About 70 percent of older people experience them at night. They're related to the cramps that come on during athletic performance, but they are not exactly the same. Poor circulation might contribute, but so many people have them that it cannot be the only reason. A deficiency of potassium, magnesium, ...

So, you ask, how do I get my electrolytes when the Gatorade in my Camelback is a solid brick? Good question. If you can't keep it from freezing, you will have to get your electrolytes and carbs from solid food, which is easier to do in cold weather since you are loosing fewer electrolytes to begin with. In such cold weather situations, electrolytes become less of an issue, while naturally the carbs and proteins move into the limelight. After a recent hydration refresher at a police team meeting, it became apparent that snipers were having a tough time converting the high-intensity, (relatively) short duration, hydration recommendations into something applicable to the sniper/spotter role. Ward examines the significance of proper hydration in the physical and mental performance of snipers.
