Water pills-they sound relatively harmless, no? After all, water is generally associated with all the good things: glowing skin, a speedy metabolism, and the ultimate hangover cure. Yet here's any interesting tidbit: If not taken appropriately, water pills (known as loop diuretics in medical speak) can actually be pretty dangerous. Why? Because they're prescribed for people with high blood pressure or patients recovering from heart failure. Yet they're more casually known as an expedited way to try to shed pounds and/or water weight-by people with perfectly pumping hearts.
The term вЂњwater pill,вЂќ in fact, has nothing to do with the scientific composition of the medication, and everything to do with their prescribed purpose: to relieve fluid retention. However, as we know all too well, one doesn't have to be recovering from a heart attack to retain some extra water. (Just come see us any given Sunday.)
Thus, it's easy to see where things could become, shall we say, murky. Though valid when needed for legitimate health concerns, water pills sold over the counter tout some understandably tempting claims. In fact, it only took one walk down the pharmaceutical aisle at our local drugstore to notice certain words and phrases repeatedly jump out at us: вЂњweight gain,вЂќ вЂњbloating,вЂќ вЂњwater retentionвЂќ-all things we try to avoid.
But are water pills a safe solution in the fight against bloat? We tapped a couple of experts to get their medical stance on the topic. The general consensus: Tread carefully. Keep scrolling to read everything you should know before taking water pills.
WHAT ARE THEY AND HOW DO THEY WORK?
As we began our research, we quickly realized that there's an important differentiation to make when it comes to water pills: diuretics that are prescribed and diuretics that are sold over the counter. To break it down for us, we reached out to Neeru Bakshi, MD, medical director of Eating Recovery Center, Washington, and Tara Condell, a registered dietitian at Top Balance Nutrition. Considering that water pills are often taken as a weight-loss solution, we thought it was important to get information from both a medical and nutritional standpoint.
Essentially, Bakshi tells us, вЂњWater pills (also known as diuretics), are a class of medication used to help the kidneys decrease the amount of water in the body. They work by having the kidneys remove sodium from the body, and the water then follows the sodium.вЂќ Typically, she adds, they're prescribed to a patient by a medical professional to help with high blood pressure, heart failure, and edema. вЂњIf taken at the prescribed dosage, they can be very useful for people who actually need to take them.вЂќ
From a nutritional standpoint, Condell agrees. вЂњDiuretics are useful for a variety of medical conditions-even for treating acne-but should always be used under the care of a physician.вЂќ
PRESCRIPTION VS. OVER THE COUNTER
This is important. Unlike prescribed diuretics, over-the-counter water pills are not regulated by the FDA. In other words, вЂњThe ingredients listed on the box may not actually be what is in the pill you are taking,вЂќ says Bakshi. She continues, вЂњThere is also no guarantee of the concentration of the ingredients or promise that the listed benefits of the drug are what you should achieve.вЂќ (In other words, a functioning, healthy human shouldn't need to take water pills in the first place.)
Not to mention, there can be some nasty side effects вЂњincluding but not limited to, excessive urination, dehydration, constipation, dizziness, low blood pressure, muscle cramping, and elevated heart rate,вЂќ in addition to potential interactions with other medications. Which is why, Bakshi tells us, you should really only take these types of pills while monitored by your physician.В
It's important to note, however, that when taken as prescribed,В diuretics, can be safe. Side effects are still a possibility, but if taken under the care of a medical professional, these symptoms can be dealt with in a prompt and safe manner.В
Which left us wondering, how are water pills allowed to be sold over the counter?В According to Bakshi, вЂњOftentimes, certain once-prescribed medications can be sold over the counter once deemed safe to do so. This is the case for diuretics and other medications, like ones for heartburn. That being said, when a medication is able to be sold over the counter, it can lose the oversight by the FDA (as noted earlier) and thereby not need to follow the same regulations as prescribed medication for safety.вЂќ She adds: вЂњJust because a medication is available over the counter does not mean that it is safe for all people to take.вЂќ
SHOULD THEY BE TAKEN FOR BLOATING OR WEIGHT LOSS?
According to our nutritional expert, Condell, вЂњwater pills should not be a method for tackling weight loss.вЂќ And again, she adds that they should be used under the care of a physician. (Do we sound like a broken record yet?) And our physician, Bakshi, backs her up, explaining to us that historically, diuretics have been a medication that people use to try to lose weight, though it's not an effective strategy, and if anything, they might cause you to gain weight.В
вЂњDiuretics do not help in weight loss but can temporarily decrease someone's weight on the scale as they are losing water. As a response to this, the body may try to retain more water, causing swelling and an increase in weight at measured on a scale. In turn, the person may think that they need to take even more diuretics, leading them down a dangerous path.вЂќ
In short, it's imperative to talk to a medical professional before taking water pills or any other type of diuretic.В
