A recent federal report said emergency room visits linked to energy drinks increased tenfold between 2005 and 2009, jumping from about 1,000 to 13,000 per year. It’s not shocking that 44% of patients who’d consumed energy drinks had also consumed alcohol or drugs; it’s not even that bizarre that men were twice as likely as women to combine alcohol or illegal drugs with energy drinks. But what surprised me is that the report pointed out that female ER visits were more likely to involve combining energy drinks with pharmaceuticals—why would energy drinks be bad to mix with prescription drugs? And what kind does that even mean—painkillers? Antidepressants? Birth control?
I put the questions to Dr. Michael Lowenstein, co-medical director of the Waismann Method, where he treats patients with opiate dependency. He says that, while an excess of energy drinks can cause several symptoms, one of the biggest issues actually starts with our stomachs.
In fact, Lowenstein thinks that these days, the majority of Americans have what he calls “dysfunctional guts”:
There’s a lot of bacteria and yeast that shouldn’t be there, and what feeds these bad bacteria and yeast is sugar. All this simple sugar feeds the pathogens and bad stuff in the gut.
And when the gut isn’t functioning well, the immune system doesn’t function well, serotonin levels drop, and the possibility of depression, auto-immune disorders, gastrointestinal problems, and even autism goes up. Add the excessive sugar found in energy drinks into the mix, and you have a mess on your hands:
Then people will want to take medications like Prilosec to treat these symptoms, to reduce acid in the stomach. But you need acid in the stomach, to absorb calcium and magnesium and all the important vitamins. Over time, people get stuck in this vicious cycle, where they don’t absorb enough important minerals, and this leads to more health problems and more medications.
Plus (making matters in your dysfunctional gut even worse), Lowenstein says that pharmaceutical drugs can also deplete some vitamins; something they don’t put at the forefront of those happy Cialis ads:
Lipitor will deplete the body of coenzyme Q-10. Everything depletes something. We’re already a little bit dysfunctional in our diet. And with sugar—you kind of get this feedback loop, you get this boost and then it’s gone and so you crave more. With our bad diets and a little bit of a gut disfunction, we have these underlying issues and drinking energy drinks just makes it worse. It’s not one specific prescription medicine (that’s a bad mix), it’s just that kind of loop where it’s making underlying issues worse.
The caffeine and stimulants don’t help, either. If you stay under 120-130 mg of caffeine—that is, one serving—you’re “probably okay,” Lowenstein says. But many people consume more than this. Some of the larger energy drinks, like Rockstar and Monster, contain two or three servings per can. The excessive caffeine alone can have dangerous side effects like irregular pulse, high blood pressure and dehydration, but most energy drinks are also jam-packed with other stimulants like guarana (also caffeinated), taurine and B-vitamins. These carry their own risks, according to Lowenstein:
The B vitamins, the guarana, the taurine—any of those things in excess can cause nausea and vomiting. If you have hypertenion or anything like that, all the caffeine will make it worse. And … with too much caffeine, you’re not going to sleep well. You start messing with sleep-waking cycle, too.
