Are you feeling more nauseous after vaping? Struggling to go to the bathroom without extra help? Noticing heartburn and acid reflux before meals? What about bloating and cramps after eating?

If yes, then your vape might be harming your digestive system, and more specifically, your gut health.

You might be wondering why you haven’t heard about this. Unfortunately, there are still major gaps in our understanding about gut health generally, partly because it's a historically taboo subject. However, recent years have seen a surge in both the science and conversation around gut health, as the medical community continues to discover just how much our digestive system influences our overall well being. Some doctors even liken the gut microbiome to the gut’s “brain,” with real effects on not only digestion, but mood, overall health, and cognition.

If you’re a vape user, and you’re left wondering why your stomach hurts so much, you’ve come to the right place. And while there are plenty of articles , TikToks (#guttok), and studies devoted to healing your gut with juices and diets, the answer to healing your gut (and feeling better) may lie in your hands—your vape. 

Stomach pain after vaping or smoking isn’t uncommon, and there are a few possible reasons why it happens. From nicotine’s effect on digestion to added chemicals that irritate your gut, understanding the cause can help you find relief.

Smoking ultimately disrupts your gut “brain” by increasing inflammation, leading to stomach pain and overall discomfort. Smoking can also lead to a host of other (seemingly) unrelated symptoms: tongue discoloration, loss of smell and taste, nausea, gastric burning, and altered bowel habits. And in the long term, nicotine dependence can lead to chronic conditions, most notably “inflammatory bowel disease, irritable bowel syndrome, peptic ulcer disease, and gastrointestinal cancer,” according to NIH . Simply put, nicotine, on its own, causes stomach pain.

Unfortunately, vaping doesn’t always offer a safer alternative. One study found that vaping liquid is highly damaging , causing even more systemic inflammation and significantly altering your gut flora. Dr. Frank Lipman notes, "vaping does compromise the gut lining and leads to a leaky gut with the consequent possibility of triggering inflammation in all parts of the body." 

Vaping can affect your gut health in ways that aren’t always obvious at first. If your digestive system feels off, your vape might be playing a role. Some common symptoms include:

• Abdominal pain or cramping

• Bloating or excessive gas

• General stomach aches or discomfort

• New or worsening food sensitivities

• Irregular digestion or changes in bowel habits

These symptoms may point to a compromised gut barrier or inflammation triggered by nicotine or other chemicals in vape products.

While vaping is known to cause bloating, cramps, and other gut discomfort, it can also lead to additional digestive issues. Symptoms like nausea or diarrhea may show up as your body reacts to nicotine or other additives in vape products.

Nicotine can also cause stomach pain because it stimulates your bowels so much. Like any stimulant (think coffee), nicotine can accelerate your bowel movements. And since vapes often contain a much higher concentration of nicotine, you might notice that you need to go to the bathroom with far more urgency. The sudden influx of stimulation is a lot on your stomach, and this can lead to not only cramps, but bloating and general discomfort.

If you vape too much, side effects get even worse. This nicotine overdose, or nic sick, can lead to nausea, vomiting, stomachache, loss of appetite, headache, mouth watering, dizziness or tremors, and confusion and anxiety. It can also cause the muscles of your digestive system to contract, causing stomach pain . Symptoms generally last one to two hours, but can go up to 18 or 24 hours, depending on your exposure. And since it’s a lot easier to ingest too much when vaping, cases of nic sick are slowly on the rise. Maybe you’ve already experienced being nic sick for yourself—feeling physically ill after using your vape a little too much one day.

Nicotine withdrawals can also hurt your stomach. Common withdrawal symptoms include constipation, bloating, indigestion, gas, and general discomfort, meaning you’ll probably be feeling uncomfortable in the opposite direction. This is because your stomach is recalibrating to the loss of such a powerful stimulant on your digestive system. 

If vaping has been throwing your digestive system out of balance, quitting could be the first step toward relief. Giving your body a break from nicotine and other irritants allows your gut to recover and function more normally over time.

Like any stomach ache, quitting can be uncomfortable and difficult to manage. But the good news is that the gut can reset quickly. One study found that smoking cessation led to an increase in microbial diversity within weeks. A full reset might be possible in six months .

NRT, or nicotine replacement therapy, can help ease this pain by providing regular, pre-measured doses. That means you won’t be flooding your gut and bowel with nicotine, but you also won’t be experiencing major withdrawal symptoms. And NRT, like Jones mints , increases your chances of quitting by 50-60%, meaning you’re that much closer to a healed gut and happy stomach.
