Parasite cleanses are trending again – please don’t believe everything TikTok tells you

If you’ve spent enough time on TikTok or Instagram recently, there’s a reasonable chance the algorithm has attempted to convince you that you have parasites. Are you bloated? Parasites. Tired? Parasites. Skin playing up? Probably parasites. Struggling to sleep? Apparently, parasites again. And conveniently, once social media has persuaded you that your body is harbouring an unwanted collection of creatures, somebody is usually waiting to sell you the herbal “parasite cleanse” that promises to get rid of them.

Parasite cleanses have become one of the stranger wellness trends of 2026, with powders, drops, teas and supplement combinations appearing across social media. Ingredients can include herbs such as wormwood and black walnut, while videos sometimes feature rather graphic claims about what people believe they’ve expelled after completing a cleanse. The problem is that having common symptoms such as bloating, tiredness or digestive discomfort doesn’t automatically mean you have a parasitic infection – and there’s no good evidence that the parasite-cleansing products being promoted online are an appropriate way to diagnose or treat one.

Yes, parasites are real. That doesn’t mean you have one

It’s important not to swing too far in the opposite direction: parasitic infections absolutely exist. Some worm infections can be acquired in the UK, while others are more commonly associated with travel to parts of the world where sanitation or food hygiene differs. Threadworms, for example, are common in the UK, particularly among children, and can usually be treated with medicine obtained through a pharmacy.

Other parasitic infections may require medical investigation and prescription treatment. Depending on the suspected infection and a person’s symptoms or travel history, testing can include stool samples, blood tests or other investigations. The important distinction is that this is diagnosis followed by appropriate treatment, rather than assuming that a vague symptom means parasites and ordering a bottle of herbs from somebody on social media.

One of the problems with online parasite content is that the symptoms being attributed to parasites are often incredibly broad. Bloating, changes in bowel habits, tiredness and stomach discomfort can have numerous possible causes. If TikTok tells millions of people that common symptoms are evidence of worms, inevitably plenty of perfectly healthy people – and people whose symptoms have an entirely different explanation – are going to recognise themselves in the list.

When should you actually speak to someone?

There are symptoms where seeking proper medical advice makes considerably more sense than embarking on a DIY cleanse. NHS guidance recommends seeing a GP if you find a large worm, part of a worm or worm eggs in your poop; develop a red, itchy worm-shaped rash; have sickness, diarrhoea or stomach pain lasting longer than two weeks; or experience unexplained weight loss.

Travel history can also be important. Some infections can take a considerable amount of time to produce symptoms, so the NHS advises telling your GP if you’ve travelled abroad within the previous two years when presenting with possible symptoms of certain worm infections.

Threadworms are slightly different. Small white worms that look like pieces of thread in poo, together with intense itching around the anus particularly at night, are characteristic signs, and a pharmacist can advise on treatment.

In other words, if there’s a genuine reason to suspect parasites, healthcare professionals aren’t going to recommend that you simply ignore them. There are established ways to investigate and treat parasitic infections.

A cleanse isn’t harmless just because it’s ‘natural’

There’s also an assumption in parts of the wellness world that herbal equals harmless. It doesn’t.

Supplements and herbal preparations can cause side effects, interact with medicines and may not be suitable for everyone. Restrictive “detox” diets can create their own nutritional problems, while aggressive laxative effects may lead to diarrhoea and dehydration. Taking something powerful enough to dramatically affect your digestive system isn’t automatically evidence that parasites are leaving your body.

There’s another risk too: treating yourself for a condition you haven’t actually been diagnosed with can delay finding out what’s really causing persistent symptoms. If you’ve had ongoing diarrhoea, unexplained weight loss or persistent abdominal problems, identifying the actual cause is considerably more useful than assuming TikTok has solved the mystery.

Your body doesn’t need a quarterly parasite MOT

Perhaps the strangest idea emerging from the trend is that otherwise healthy people should routinely “cleanse” themselves of parasites as though we’re all carrying around an infestation that needs clearing out every few months.

That’s simply not how evidence-based treatment works.

If you have a parasitic infection, it should be identified and treated appropriately. If you don’t have one, there is no established health benefit to routinely taking parasite-cleansing products just in case.

Social media can be brilliant for discovering recipes, workouts and new ways of looking after ourselves. It’s considerably less brilliant when an algorithm diagnoses millions of people with the same medical condition before directing them towards somebody selling the cure.

So if your feed suddenly becomes full of people telling you that your bloating, bad night’s sleep and afternoon slump mean you’ve got worms, perhaps don’t panic.

Sometimes being tired just means you’re tired.

And if you genuinely think you might have a parasite? Skip the cleanse and speak to someone qualified to find out.
