The side effects of too much Gatorade include weight gain, vitamin toxicity, hypernatremia, hypertension and high blood sugar, according to Med-Health.net. Every 32-ounce serving of the energy drink contains 200 calories that can be stored as excess fat, which leads to weight gain as the most common side effect of Gatorade consumption.
Vitamin toxicity comes from enhanced vitamins and minerals in the sports drink. Med-Health.net states that added vitamins such as vitamin A and fat-soluble nutrients should not be consumed excessively. Hypernatremia, or overhydration of the body's cells due to lack of sodium, can be fatal in runners and athletes that consume too much fluid. Hypertension results when Gatorade is consumed alongside salty foods and the body ingests too much sodium over long periods of time. Every bottle of the sports drink contains 56 grams of sugar that can lead to high blood sugar with detrimental effects to diabetics.
Pediatricians feel that children and teenagers should only use sports drinks such as Gatorade during times of intense physical exertion. NPR reports that these drinks have sugar as the main ingredient, which leads to obesity and tooth decay. Children should drink milk, juice and plenty of water instead.
CNN reveals that PepsiCo Inc. removed brominated vegetable oil from Gatorade in January 2013 after one teenager's successful campaign to have the controversial substance banned from the drink. The sports drink company claims it removed brominated vegetable oil after a year of research.
