Tea itself rarely causes bloating. The usual culprits are what goes into the cup or how you drink it: milk if you're lactose intolerant, caffeine on an empty stomach, strongly brewed black tea, or drinking a large amount quickly. Peppermint and ginger are the teas most often studied for easing digestive discomfort.
Does Tea Really Cause Bloating?
For most people, no. Registered dietitians find no strong link between plain tea and bloating, and some herbal teas are associated with a calmer stomach. When bloating does show up after a cup, it usually traces back to one of four causes below.
Livestrong: Can Tea Cause Bloating?
The 4 Real Causes of Bloating After Tea
- Milk and lactose intolerance. Adding milk or cream can cause gas and bloating in people who don't fully digest lactose. Try the same tea without milk, or switch to a lactose-free or plant-based milk, to see if that's the cause.
- Caffeine on an empty stomach. Caffeine in black and green tea stimulates the digestive tract, which some people feel as discomfort, especially first thing in the morning before eating.
- Strongly brewed black tea. Long steeps pull out more tannins, which can irritate a sensitive stomach. Shorter steeps (3 to 4 minutes) or drinking tea with food usually helps.
Livestrong: Digestive Side Effects of Black Tea - Drinking a large amount quickly. Gulping a big mug, especially through a straw or alongside a meal, means swallowing more air and liquid at once, which can leave you feeling full and bloated.
Check your sweetener too. Some sugar-free sweeteners, particularly sugar alcohols, are a common bloating trigger on their own.
Does Green Tea Cause Bloating or Gas?
Green tea itself rarely causes gas. When it does bother people, it is usually because of how it is brewed or when it is drunk. Green tea contains caffeine and tannins, and both can irritate an empty stomach. Brewing it too hot or too long makes it more bitter and harsher on the gut.
To make green tea gentler, drink it with or after food, brew at 175–185°F for 2–3 minutes, and keep to 2–3 cups a day. If you still feel bloated, try a caffeine-free herbal tea in the afternoon instead.
Teas That May Help With Bloating
- Peppermint: Peppermint oil capsules have been studied for IBS symptoms in adults, according to the NIH’s National Center for Complementary and Integrative Health. Peppermint tea is considered safe but has been studied far less, and it can worsen heartburn in some people.
- Ginger: In a small 2011 study, 1.2 grams of ginger helped the stomach empty faster after a meal, though it did not change how full or bloated people felt.
- Chamomile: Traditionally used to settle the stomach, and naturally caffeine-free.
- Fennel: Long used in traditional practice for gas and bloating.
These teas aren't a treatment for a medical condition. If bloating is frequent, severe, or comes with pain or other symptoms, talk with a doctor.

What About Detox Teas?
Many “detox” blends contain helpful, flavorful ingredients like ginger, peppermint, dandelion, and hibiscus. But your liver and kidneys handle detoxification on their own, and there is no good evidence that bloating is a sign of your body “flushing toxins.” If a detox tea leaves you bloated, look at its ingredients: some contain senna or other laxative herbs, which can cause cramping and bloating and aren't meant for daily use.

How to Brew for a Gentler Cup
- Use one teaspoon of loose tea or one tea bag per 8 oz cup.
- Steep herbal teas at about 200°F (93°C) for 5 to 7 minutes.
- Steep green tea at 160 to 180°F (71 to 82°C) for 2 to 3 minutes, and black tea for 3 to 4 minutes, to keep tannins in check.
- Cover while steeping to keep the aromatic oils in the cup.
Quick Tips to Avoid Bloating
- Skip the milk for a few days to test for lactose sensitivity.
- Have caffeinated tea with or after food rather than on an empty stomach.
- Sip slowly instead of drinking a large mug all at once.
- Choose caffeine-free herbal teas like peppermint, ginger, or chamomile in the evening.
Frequently Asked Questions
Why does tea make me bloated? The most common reasons are milk or cream, caffeine on an empty stomach, very strong brews, and drinking large amounts quickly. The tea leaf itself is rarely the cause.
Does green tea make you gassy? Usually not. Some people feel gassy or queasy when they drink it on an empty stomach or brew it too strong. Try it after a meal and brewed cooler.
Is peppermint tea good for bloating? Many people find it soothing after a meal, and peppermint oil has research for IBS. Skip it if you have heartburn or reflux, since peppermint can make those worse.
Do detox teas cause bloating? Some do. Detox blends that contain senna act as laxatives and can cause cramping and bloating. They are not meant for daily use.
When should I see a doctor about bloating? See a doctor if bloating lasts more than a few weeks, keeps getting worse, or comes with pain, weight loss, or changes in bowel habits.
The Bottom Line
Tea is rarely the real cause of bloating. Milk, caffeine timing, strong brewing, and drinking quickly are the usual triggers, and each is easy to adjust. Peppermint and ginger teas are gentle options to keep on hand after meals.
