Weight loss injections are everywhere—from Instagram ads to celebrity endorsements. But now that millions have tried them, we’re hearing the other side of the story. With more and more people turning their backs to weight loss jabs, we spoke to 100s of patients who choose bariatric surgery over weight loss injections. Here’s what real people are saying about their weight loss jab experience:

“It didn’t work.”

Despite the hype, many people don’t see meaningful weight loss. They follow the guidance, take the jabs—and the scale barely moves.

“It worked last time… now it’s doing nothing.”

Some see results on the first round, but when they try again, their body doesn’t respond the same way. Tolerance builds, and the effectiveness fades.

“I felt really sick on them.”

Nausea, vomiting, dizziness, and fatigue are common. For some, it’s enough to make everyday life feel miserable.

“My GP said it’s not safe for me.”

Patients with underlying health conditions are being warned off by doctors. Without full medical screening, injections can pose serious risks—especially for those with heart, kidney, or hormonal issues.

“It started at £120/month. Now I’m paying over £250.”

The ‘starter dose’ may be affordable, but most people need more over time. As your body adapts, higher doses become necessary—and so do the higher costs.

“The cravings came back worse than before.”

Once you stop, the appetite suppression fades fast. Many say the hunger returns with a vengeance, and the weight piles back on just as quickly.

“It messed with my sleep, mood, and body.”

Insomnia, anxiety, bowel issues, and nausea are widespread. In rare but documented cases, more severe effects include vision loss, thyroid inflammation, bowel damage, and even increased cancer risk.

“It’s just another fad diet.”

Like the diet pills of the ’80s and ’90s, jabs are turning into another cycle of “lose it, gain it.” Each time, your metabolism takes a hit—leaving you heavier, more discouraged, and out of pocket.

“I’m scared of the long-term effects.”

There’s still so much we don’t know. These drugs haven’t been around long enough to fully understand their long-term impact on brain health, hormone balance, fertility, or chronic disease risk. For many, that uncertainty is reason enough to think twice.

“It shows up in the post—no real support.”

Mail-order weight loss jabs are mass-marketed with no ongoing care. Unlike weight loss surgery, which includes a full team—surgeons, nurses, coordinators—these injections often come with no real medical oversight. The NHS is already reporting a rise in serious complications like liver failure, dementia, and bone deterioration.
