What Happens When You Wear A Waist Trainer With dozens of celebrities like Khloé Kardashian, Blac Chyna, and Jessica Alba endorsing waist trainers on Instagram and in magazines, using waist trainers is what is trending now. Waist trainers are known to add curves and flatten post baby tummies, helping women feel good about their bodies. But the science behind waist training is not so hot — experts say the devices can cause acid reflux, pulmonary edema, and more. Below is a list of what happens to your body when you wear a waist trainer, body part by body part. Waist The trainer will compress your waist while you are wearing it, pulling your skin, fat, muscles, and organs tighter, which makes you look slimmer. What will not happen: any permanent loss of inches around your waist. “Wearing a corset won’t make you lose fat around your waist,” Holly Phillips, MD, a New York City internist, told Yahoo Health. Your waist will be trimmer while you’re wearing it, and immediately after removing it, but it won’t make any lasting difference. Lungs While most trainers do not come up high enough to compress your lungs, wearing one does make it harder to allow air into your diaphragm, leaving your lungs starved for oxygen. “Wearing [a waist trainer] for a long amount of time makes it hard to breathe, so you’re taking more shallow breaths,” Phillips says. It can also “lead to fluid in the lungs,” putting you at risk for pulmonary edema or pneumonia. Brain Those shallow breaths can cause an oxygen shortage, leaving you feeling dizzy and lightheaded. This can happen at a micro level (your thoughts may seem scattered or hard to follow) or macro level (you can lose consciousness). Rib cage While it is possible that excess fat can make your chest look bulkier than it is, some women just have larger rib cages than others. A waist trainer cannot change that, but using a too-small trainer or corset can cause your ribs to bruise, which some may mistake for weight loss or a slimmer rib cage. “What is a myth is that you can change your bone structure,” Phillips says. “For [adult] women, your bones are formed. You can bruise them and harm them, but you can’t change them.” A waist trainer won’t slim down a wide rib cage — it’ll just leave it bruised, or worse. Veins Not only can wearing a waist trainer thin out your air supply, it can also “decrease blood flow in your veins, cause problems with blood clots, and put more pressure on your heart,” Andrew Miller, MD, a plastic surgeon in New York City, told Yahoo Health. Stomach A waist trainer may help you eat less, but it comes at a price. “Some people think of it as external gastric bypass surgery,” Phillips says, because your stomach is so compressed that you can’t take more than a few bites of food at a time. And sure, “anyone who doesn’t eat as much is going to lose weight,” Miller echoes. That said, you will have some unpleasantness when you do eat because of the pressure on your organs. “You’re compressing your stomach so much that when you take a bite of food, you end up with acid reflux,” says Phillips.
