What Is a Diuretic and Why It Matters for Your Dehydration Risk

By now, you’ve probably heard of diuretics. They’re one of the most common solutions for heart conditions and they’re also popular as weight loss pills. But as with most things, diuretics can have side effects — one of which is particularly concerning is dehydration. Whether you have to take diuretics for high blood pressure or consume diuretics like caffeine to stay awake, it’s important to know how they can impact your health.

Here, we’ll answer the question of “what is a diuretic” and show you the different types of diuretics. You’ll learn how diuretics can heighten your risk of dehydration. Plus, you’ll discover how you can avoid the condition with an oral rehydration solution like DripDrop ORS — a fast, effective remedy for tackling dehydration that can be exacerbated by diuretics.

What Is a Diuretic?

Are you wondering what is a diuretic? A diuretic is a substance that increases urination, which is also known as diuresis. Diuretics include natural substances such as caffeine and alcohol as well as medications including water pills and blood pressure medications. Some antidepressants such as beta-blockers, heart medications such as angiotensin-converting enzyme (ACE) inhibitors, and water pills prescribed for weight loss are also diuretics.

As medications, diuretics are designed to increase the secretion of water and electrolytes such as sodium through urine. They are specifically used to adjust fluid levels, which is why they’re commonly used to treat medical conditions like kidney diseases and heart conditions, including high cholesterol and heart attacks. For example, a person with congestive heart failure may develop a build-up of fluid — known as edema — and diuretics can help reduce this excess fluid retention and lower blood pressure.

Here are some of the most common types of diuretics.

  • Thiazide diuretics: Frequently prescribed to treat high blood pressure (hypertension), these diuretics, which include carbonic anhydrase inhibitors, help to relax blood vessels and decrease fluid retention. Common examples include metolazone (Zaroxolyn), indapamide (Natrilix), hydrochlorothiazide (Microzide), chlorothiazide (Diuril), and chlorthalidone (Thalitone).
  • Loop diuretics: Designed as a therapy for heart failure, these diuretics include torsemide (Demadex), furosemide (Lasix), ethacrynic acid (Edecrin), and bumetanide (Bumex). These diuretics inhibit the reabsorption of sodium and chloride, preventing excess water retention.
  • Potassium-sparing diuretics: One side effect of loop and thiazide diuretics is a loss of potassium since electrolytes are excreted in urine. Without enough potassium, you can develop hyperkalemia, a type of dehydration. This can cause problems including irregular heartbeat if you take these diuretics without a potassium supplement. Potassium-sparing diuretics are designed to reduce fluid levels without affecting potassium levels. These include amiloride triamterene, spironolactone (an aldosterone antagonist also known as Aldactone), and eplerenone.
  • Calcium-sparing diuretics: Like potassium, calcium is an electrolyte that is excreted in urine. These diuretics are used for heart conditions in people that may take other medications that affect calcium levels or for those with osteoporosis and other calcium deficiencies.

Herbs and botanicals also act as natural diuretics. Just think of how you feel after you drink a cup of java or down a beer after work with your colleagues. Both caffeine and alcohol work as diuretics. They increase urine production and trigger the excretion of water and electrolytes.

The Connection Between Diuretics and Dehydration

So why does this matter? Diuretics have several side effects, one of the most concerning is dehydration. Dehydration is a condition where you lose more fluids and electrolytes than you take in. It can lead to headache and extreme thirst, and severe cases can cause coma and brain damage.

One of the leading causes of dehydration is fluid loss through increased urination. Since diuretics increase urine production, they heighten the risk of developing the condition. This is especially concerning if you don’t consume enough fluids throughout the day.

Unfortunately, older individuals are more susceptible to dehydration. Not only do elderly individuals suffer from medical conditions that require diuretics, but they also are less aware of when they’re dehydrated. That’s because our thirst response — one of our body’s main signals that we’re dehydrated — decreases as we age. That means elderly adults may not know they’re dehydrated until it’s too late.

To compound the problem, many older adults don’t want to drink more fluids because they don’t want to use the restroom more often. This is particularly common for individuals that take diuretics, which already increase urine production.

But it’s not just older adults. All of us are at risk of dehydration, particularly if we consume diuretics like medications and alcohol. That doesn’t mean that you have to resign yourself to being chronically dehydrated. Reach for an oral rehydration solution like DripDrop ORS. It can help you replenish fluids and electrolytes that you lose when taking diuretics, thus helping you avoid dehydration.

When you're in a state of dehydration, no amount of water alone is enough. Your body needs the perfect balance of sodium and glucose to help absorption. With the precisely balanced ratio in DripDrop ORS, you can replenish vital electrolytes and fluids to relieve dehydration quickly. Plus, DripDrop ORS supplies vitamins like zinc, potassium, and magnesium, which are essential to support your overall health.
