• A current examine discovered numerous “hidden” uncomfortable side effects of GLP-1 medication like Ozempic, together with chills, scorching flashes, and irregular intervals.
• The researchers used self-reported Reddit knowledge to look at the real-world results of those drugs.
• An knowledgeable weighs in on why hidden uncomfortable side effects, similar to Ozempic chills, could happen.

GLP-1 drugs, like Ozempic, Wegovy, and Mounjaro, have numerous recognized uncomfortable side effects, together with nausea, fatigue, constipation, and diarrhea.

Nonetheless, a current examine revealed in Nature Health discovered that GLP-1 medication may additionally include sure “hidden” uncomfortable side effects.

The researchers analyzed 410,198 Reddit posts that talked about both semaglutide or tirzepatide. They discovered a complete of 67,008 customers who self-reported utilizing these drugs. Of these, 43.5% posted about a minimum of one facet impact.

Reproductive points, similar to menstrual irregularities and temperature-related complaints, like chills and scorching flashes, had been probably the most notable unrecognized uncomfortable side effects of GLP-1s.

Jeffrey Lee, MD, a double board-certified plastic surgeon and founding father of JL Plastic Surgical procedure in Boston, MA, who was not concerned within the examine, spoke to Healthline about these “hidden” uncomfortable side effects, why they might happen, and what folks could misunderstand about GLP-1s from social media posts.

This interview has been frivolously edited and condensed for readability and size.

Lee: The most typical uncomfortable side effects I see in apply are gastrointestinal, issues like nausea, bloating, or constipation.

These are sometimes short-term and infrequently dose-dependent, that means they’ll enhance over time or with a dosage adjustment.

Of the lesser-known uncomfortable side effects talked about within the examine, I’ve sometimes had sufferers report fatigue, nevertheless it’s not one thing I see continuously.

I’ve not personally seen many of the different signs highlighted within the examine in a constant or clinically vital means.

Lee: GLP-1 agonists primarily have an effect on the gastrointestinal system, however additionally they act on the brain, significantly the hypothalamus, which regulates many core features, together with hormones, temperature, and urge for food.

Due to this, it’s believable that some sufferers may expertise broader systemic results, together with hormonal or temperature-related signs.

That mentioned, these results aren’t but effectively established clinically, and extra analysis is required to find out whether or not they’re straight brought on by the remedy or influenced by components similar to weight reduction, metabolic adjustments, or particular person physiology.

Clinically, we’re seeing that some sufferers report a lowered sense of reward from sure behaviors.

For instance, there have been reports of people with alcohol use points experiencing a decreased urge to drink. This means that GLP-1s could blunt the reward response, which could possibly be helpful in some contexts.

Nonetheless, that very same mechanism may additionally translate right into a dampening of emotional highs and lows, which some sufferers could interpret as apathy or decreased libido. That is nonetheless an rising space of analysis, nevertheless it’s one of many extra attention-grabbing potential results of those drugs.

Lee: Affected person habits can completely play a job.

If somebody is actively limiting consumption past what the remedy is already doing, they might expertise signs like irritability or temper swings.

Alternatively, if a affected person is totally reliant on the remedy and experiences little to no starvation, these fluctuations could also be much less noticeable.

So there’s typically an interaction between the remedy’s results and the affected person’s behavioral response.

Lee: One of many largest challenges with social media is that it captures anecdotal, self-reported experiences with out context.

It may be troublesome to find out whether or not a symptom is straight brought on by the remedy, associated to speedy weight reduction, influenced by different drugs, or tied to underlying well being situations.

With out that medical context, it’s straightforward for associations to be made that aren’t essentially causal. That’s why it’s vital to interpret these stories fastidiously and along side medical knowledge.

Lee: These limitations are vital. For findings to be broadly relevant, the examine inhabitants must replicate real-world sufferers when it comes to age, gender, medical historical past, and dosing.

Self-reported knowledge, particularly from platforms like Reddit, can introduce bias, because it typically captures a narrower or extra vocal subset of customers.

That mentioned, research like this could nonetheless be priceless as an early sign. They may help generate hypotheses and information extra rigorous, managed analysis that permits us to attract extra definitive conclusions.
