Now, he’s revealed the three shocking ways in which vaping damages the gut; and some of them are irreversible, reports What’s The Jam.
In the clip, which has racked up 262,000 views and over a thousand likes, he begins by explaining that it disrupts the gut microbiome.
Dr Sethi, 42, from California, US, says: “Vaping chemicals can throw off the balance of good bacteria in your gut, leading to GI issues and chronic inflammation.

“Research shows that E-cigarette vapour can reduce beneficial gut bacteria.”
Secondly, he says that if you’re puffing on a vape and experiencing a sensitive stomach, they could be linked.

“The chemicals in vape liquids can irritate your gut lining, increasing the risk of conditions [such as] irritable bowel syndrome.
“Studies indicate that vaping can increase gut permeability and inflammation, worsening conditions like Crohn’s disease.”

Lastly, Dr Sethi explains that vaping weakens your gut barrier, meaning harmful toxins have an easy way through.
He said: “[These pass through] the gut lining into the bloodstream, which can increase your risk for autoimmune problems.”
To quit, or reduce, vaping, Dr Sethi has a few key tips.
He added: “Start by setting clear goals and gradually lower nicotine intake.
“Replace vaping with healthier habits, like chewing gum or exercising.
“Seek support from friends, family, or groups.
“And avoid triggers that increase cravings.
“With patience and persistence, you can break the habit and reduce health risks.”
