Are weight-loss drugs worth it? Understanding the risks and benefits

I was scrolling through my Instagram feed the other day, and there it was again—a shiny ad promising effortless weight loss with just one “miracle” pill or injection. The before-and-after pictures were hard to ignore, and for a second, I actually clicked on the comments, thinking, “Could this really work?”

Clearly, I wasn’t the only one interested. A FAIR Health White Paper report shows that over 2% of U.S. adults now use GLP-1 weight-loss medications such as Ozempic and Wegovy for obesity, reflecting a dramatic rise in usage—nearly a 600% increase in the past six years.

But then, reality hit me. Beneath the glossy surface, I started to think about what those ads weren’t saying. The cost, not just in dollars but in side effects, long-term health risks, and the emotional toll of chasing an impossible ideal. It left me questioning—how far would someone go for a quick fix, and at what real cost?

Soaring demand, soaring spending

It’s no secret that weight-loss drugs are having a moment. GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound have taken over the market, and the numbers are staggering. In 2023 alone, spending on these drugs in the U.S. shot up to nearly $72 billion, a fivefold increase since 2018. Analysts even predict that the global market will hit a whopping $150 billion by 2035.

With that kind of money flying around, it’s clear that a lot of people are using these drugs. In fact, about one in eight U.S. adults says they’ve tried them. What’s even more telling is that people are sticking with them. In 2025, about 66% of users were still on the drugs after a year, a big jump from just a third a few years ago. This shows a huge shift in how people view these medications, not as a temporary solution, but as a long-term part of their lives.

But what’s driving this massive demand? Is it just about health, or is there something else going on?

The “skinny” price tag

Let’s talk money, because these drugs are not cheap. For a long time, the monthly cost was around $1,000 per person. Ouch. Recently, prices have started to come down a bit as drug companies introduce savings programs. For instance, Wegovy’s price dropped to $499 a month for some, and Zepbound came out with a $349 monthly starting price for self-payers, NBC News reports.

While that sounds better, it’s still a lot of cash. It’s no surprise that nearly half of all users report feeling the financial strain. And it’s not just individuals feeling the pinch. Employers are also seeing their health care costs spike, with premiums expected to jump 7% to 8% in 2025, partly because of these drugs. As Dr. David Rind from the Institute for Clinical and Economic Review (ICER) noted via Reuters, “Prices have significantly decreased. But payers are still encountering challenges regarding affordability.”

Newer options, like an oral version of semaglutide, are on the horizon and could shake things up even more. But for now, the cost remains a major hurdle for many. And this raises an important question: who gets left behind when the best treatments are only available to those who can afford them?

The Good, The Bad, and The Ugly

Okay, let’s get into the part everyone wants to know about: what do these drugs actually do to your body? Experts like Dr. Daniel Drucker at the University of Toronto have praised them for helping people achieve an average weight loss of 15% to 20%. That’s a big deal. Studies also show they can lower the risk of heart attack and stroke by 20% over roughly three years, and a 30% reduction in major cardiovascular events.

But it’s not all good news. Dr. Ziyad Al-Aly, a clinical epidemiologist, found it “eye-opening…to see all these different hits in different organ systems.” There are some pretty common side effects that you should know about.

What to Expect

Here are some of the physical effects, both good and bad:

• Common Side Effects: Get ready for some quality time in the bathroom. Nausea, vomiting, diarrhea, and constipation are very common. In fact, users have a 30% higher risk of some kind of gastrointestinal issue. Fatigue is also on the list.
• Serious (But Rare) Risks: Though less common, there are some scary possibilities. The risk of acute pancreatitis is nearly 2.5 times higher, warns the British Heart Foundation. Some people develop kidney problems, which can be sneaky and not show symptoms until they’re advanced. Another terrifying condition is gastroparesis, or paralysis of the stomach, which seriously messes with digestion.
• Other Health Impacts: It doesn’t stop there. Some data (eg, from the British Heart Foundation) suggests an 11% higher risk of arthritis and a 6% higher risk of low blood pressure. For older adults, there’s also concern about muscle loss and malnutrition, which can make them more frail.

On a more positive note, some early research hints that these drugs might help reduce the risk of addiction and dementia. But we’re still in the early days of understanding all the long-term effects.

Lesser-Known Costs and Consequences

The price of getting skinny isn’t just paid with money or side effects. There are other, more hidden costs that often get overlooked in the excitement.

The Social and Psychological Toll

Dr. Thiara from the University of California, San Francisco, has pointed out something really concerning. She says, “We’re living in a world that values thinness so much…patients watching GLP-1 TikTok videos think vomiting is normal. It’s not.” People feel so much pressure to succeed that they push through severe side effects, thinking it’s just part of the process. Is that really healthy?

Hidden Health Risks for the Elderly

For older patients, the risks can be even greater. Dehydration from vomiting or diarrhea can worsen irregular heart rhythms (arrhythmias) and increase frailty. This puts them at a higher risk for falls and infections, which can be life-threatening.

Long-Term Dependency

You can’t just stop taking these drugs. If you do, the weight often comes right back.
A team from Peking University People’s Hospital in China found that most patients regain significant weight within about eight weeks of stopping anti-obesity medications, with weight regain continuing for up to 20 weeks.

This means you’re locked into a long-term, expensive commitment. It’s not a one-and-done solution. IMO, this is one of the biggest downsides that isn’t talked about enough.

Fake Drugs

The huge demand has also led to a rise in fake, compounded versions of these drugs. In recent months, Customs and Border Protection (CBP) officers in the U.S. seized nearly 17,000 units of counterfeit injectable GLP-1 drugs shipped to 40 states in just one week.

These copycats are unregulated and can be dangerous.

Unequal Access

At the same time, high prices and spotty insurance coverage mean that the people who might benefit most from these drugs, medically speaking, often can’t get them. Only about 36% of employer-sponsored insurance plans cover GLP-1 drugs for both diabetes and weight loss, while the majority (55%) cover them for diabetes only.

Medicaid coverage is fragmented: only about 13–14 states currently include GLP-1 obesity medications in their Medicaid benefit, but several states are now cutting these benefits due to rising costs. This just makes existing health disparities worse.

A Word from the Experts

Don’t just take my word for it. Here’s what some of the top experts in the field are saying.

Former FDA commissioner Dr. David Kessler warned, “We may conclude that this has been a significant failure unless we can learn to implement these drugs effectively in real-world settings.” His point is that having a powerful drug isn’t enough. We need to figure out how to use it safely and make it accessible to everyone who needs it.

The conversation around these drugs needs to change. It’s not just about getting skinny fast. It’s about understanding the full picture, from the financial burden to the long-term health risks.

Is It Really Worth It?

So, after all this, what’s the final verdict? Weight-loss drugs are more effective and accessible than ever before. They offer real hope for people who have struggled with obesity and related health problems for years.

But the cost is heavy. It’s a complex issue with no easy answers. While the idea of a quick fix is tempting, it’s important to remember that there’s no such thing as a free lunch. These drugs demand a lot from your body, your bank account, and your mental well-being.

If you’re thinking about trying them, talk to a doctor you trust. Have an honest conversation about the pros and cons. And remember that true health is about more than just a number on a scale. It’s about feeling good, inside and out.
