A stomach that suddenly swells after a meal, that won't go down by the end of the day, that has you discreetly undoing your trouser button in a meeting: a bloated stomach regularly affects 1 in 3 women, and 8 in 10 women occasionally. And the most frustrating part is that no diet seems to work, because it isn't a weight issue.

The truth is that a bloated stomach can have 7 different causes, and the solution depends entirely on which one applies to you. Here's how to identify your type, plus a complete method to de-bloat for the long term with the right plants, the right diet and the right routine.

Bloated stomach: what is really happening in your body

A stomach that "swells" is not a stomach that is gaining weight. It's usually abdominal distension linked to 3 possible phenomena, sometimes combined:

• Gas produced by food fermenting in the colon
• Water retention in the tissues of the abdomen
• Sluggish transit, which lets matter build up in the colon

Depending on the main cause, your stomach will swell at different times (after meals, at the end of the day, around your period, after certain foods…) and the solution won't be the same. That's why pinpointing your type is the essential first step.

The 7 possible causes of a bloated stomach

1. Digestive fermentation (gas)

Some foods ferment in the colon and produce gas: pulses, cabbage, onions, garlic, certain fruits and sweeteners such as sorbitol. The stomach swells 2 to 4 hours after the meal, sometimes with wind and gurgling.

What can help: tangerine peel, ginger, peppermint and Chinese hawthorn. That's exactly the combination in Zero Belly Tea, a blend designed for digestive comfort and to limit fermentation.

2. Local water retention

The stomach swells gradually towards the end of the day or in hot weather, with a feeling of tightness. It's linked to poor lymphatic circulation and too much salt in the diet, and often goes hand in hand with swollen ankles or heavy legs.

What can help: plants traditionally used for drainage (dandelion, nettle, lotus leaves), cutting down on salt, drinking more still water and moving every day.

3. Sluggish transit

The stomach feels bloated all the time, with a feeling of fullness that won't go away. Bowel movements are infrequent or difficult, often alongside a general feeling of heaviness.

What can help: Colon Cleanse Tea (Pu'er, ginger, senna) for an occasional boost, or the Teatox for a complete 28-day approach.

4. Premenstrual syndrome

The stomach swells in the 5 to 7 days before your period. This is linked to hormonal fluctuations (oestrogen/progesterone) that encourage water retention and digestive sensitivity. It usually disappears after the first days of your cycle.

What can help: gentle drainage a few days before your period, a low-salt diet, a course of magnesium, and soothing plants for digestive comfort (Zero Belly is a good fit).

5. Stress and anxiety

The stomach swells in stressful moments, before important events or when your mind is overloaded. The gut-brain axis is very sensitive: chronic stress disrupts digestive motility and the balance of your gut flora.

What can help: deep breathing, enough sleep, adaptogenic plants (Schisandra, found in Zero Belly), and cutting back on stimulants (coffee, alcohol) during stressful periods.

6. Food intolerances or sensitivities

The stomach swells every time after specific foods. The most common culprits: lactose (dairy), gluten (wheat, rye, barley), FODMAPs (onions, garlic, certain fruits) and artificial sweeteners. Often accompanied by other symptoms (diarrhoea, tiredness, headaches).

What can help: keeping a food diary to identify trigger foods, trying a 3-week elimination followed by reintroduction, and seeing a nutritionist if symptoms are pronounced.

7. An imbalanced gut microbiota

Often after a course of antibiotics, a stomach bug, a period of intense stress or a heavily processed diet. Beneficial flora is depleted in favour of gas-producing bacteria. The result: chronic bloating, irregular transit and sometimes other symptoms (tiredness, skin, immunity).

What can help: a diet rich in prebiotic fibre (vegetables, pulses, fresh fruit), fermented foods (kefir, sauerkraut, kimchi, yoghurt), and sometimes a supervised course of probiotics.

Identify your type of bloating in 4 questions

To target the right approach, answer these 4 questions:

1. When does your stomach swell the most?

• After meals → probable cause no. 1 (fermentation) or no. 6 (intolerance)
• Gradually, towards the end of the day → probable cause no. 2 (water retention)
• All the time → probable cause no. 3 (sluggish transit) or no. 7 (microbiota)
• Before your period → probable cause no. 4 (PMS)
• During stressful periods → probable cause no. 5 (stress)

2. Are there any other associated symptoms?

• Gas, wind → fermentation or microbiota
• Heavy legs, swollen ankles → water retention
• Infrequent or hard stools → sluggish transit
• Tiredness, headaches after certain foods → intolerance

3. What is your current lifestyle like?

High stress? Not enough sleep? Sedentary? Frequent travel? All of these factors often make the underlying cause worse.

4. Has there been a recent trigger?

Antibiotics, a stomach bug, a change in diet, a period of overload? This often points to a specific cause.

Zero Belly Tea: our signature anti-bloating blend

After years of listening to what our customers were going through, we created Zero Belly Tea specifically to address digestive bloating and after-meal comfort. Today it's our most targeted blend for this issue.

The ingredients

• Fujian Narcissus Oolong tea — a semi-fermented tea rich in polyphenols, with a gentle aromatic base
• Lotus leaves (Nelumbo nucifera) — used in traditional Asian medicine to support the elimination of retained water
• Schisandra chinensis (Wu Wei Zi) — a traditional Chinese adaptogenic berry, traditionally used to support the liver and the body's balance in the face of stress
• Tangerine peel — traditionally used for digestive comfort after meals, particularly for feelings of fullness and bloating
• Crataegus pinnatifida (Chinese hawthorn) — supports the digestion of rich meals and microcirculation

Why this blend helps with a bloated stomach

Unlike the Teatox with its structured morning + evening routine, Zero Belly is a flexible single tea to drink 2 to 3 times a day, ideally after meals. Its formula combines 3 angles:

• Limiting fermentation with tangerine peel and hawthorn
• Gentle drainage with lotus leaves
• Adaptogenic support with Schisandra (helpful for bloating linked to stress and hormonal sensitivity)

Because it contains no senna, it's an ideal tea for anyone who doesn't want a laxative effect, travels often, or prefers regular daily use.

The complete routine for a bloated stomach

When you wake up

A glass of warm water with lemon on an empty stomach to gently wake up your digestive tract. If you're doing the Teatox, have the Morning Tea with breakfast.

At breakfast

Choose foods that are easy to digest in the morning: oat porridge, plain yoghurt, fresh fruit. Avoid pastries and fruit juices, which cause bloating.

After lunch

A cup of Zero Belly Tea to support digestion and limit fermentation. This is the key moment: a digestive infusion right after a rich meal really transforms how comfortable your afternoon feels.

Mid-afternoon

A 10–15 minute walk if possible, to get digestion moving and avoid stagnation. Avoid snacking (snacking keeps fermentation going all day).

At dinner

Keep it light, with plenty of cooked vegetables (easier to digest than raw ones in the evening) and lean protein. Limit pulses, cabbage and onions in the evening if you're sensitive.

One hour after dinner

A 2nd cup of Zero Belly Tea, or the Evening Tea if you're doing the Teatox. Go to bed early if you can (the colon works better at night).

10 foods to favour for a bloated stomach

• Cooked vegetables (courgette, carrot, fennel, spinach, chard) — easier to digest than raw
• White rice, quinoa, sweet potato — starches that go down well
• White fish and eggs — lean proteins that are easy to digest
• Vegetable broths — soothing and draining
• Ripe banana, papaya, pineapple — easy-to-digest fruits (papaya contains papain, pineapple bromelain)
• Fresh ginger — grated over dishes or as an infusion
• Fresh mint — as an infusion or sprinkled over food
• Plain yoghurt or kefir — beneficial flora (unless you're lactose intolerant)
• Cooked oats — gentle fibre, ideal for breakfast
• Lukewarm still water — not ice-cold, which shocks the digestive system

8 foods to limit when your stomach is bloated

• Unsoaked pulses (lentils, chickpeas that haven't been properly prepared)
• Raw cabbage (cauliflower, broccoli, kale in large quantities)
• Raw onions and garlic in large quantities
• Fizzy drinks and beer — add gas straight into the digestive tract
• Sweeteners such as sorbitol and xylitol (chewing gum, "light" products)
• Very fatty or fried dishes — slow down digestion
• Too much raw fruit at the end of a meal — ferments
• Milk and fresh cheeses if you're sensitive to lactose

Which programme to choose for your profile

You want an anti-bloating tea to drink every day, without a laxative

Zero Belly Tea: 2 to 3 cups a day, ideally after meals. A flexible, senna-free format for daily use. Perfect when travelling, at the office, or alongside an already healthy diet.

You also have slow transit and often feel heavy after rich meals

28-day Teatox: Morning Tea + Evening Tea, 12 plants traditionally used to support drainage, the liver and regular transit. Our most complete programme to lastingly reset your digestive comfort.

You have marked constipation that contributes to your bloating

Colon Cleanse Tea for targeted evening use (Pu'er + ginger + senna), or Laxative Teatox for a complete morning + evening approach over 14 or 28 days.

You want to combine daily anti-bloating support with a periodic programme

The ideal approach: Zero Belly as your daily maintenance routine, then the Teatox once a quarter (4 weeks of the programme, then back to Zero Belly). It's what many of our long-standing customers do.

When to see a doctor

Most bloating responds very well to a natural approach. However, some warning signs should prompt you to see a doctor:

• Sudden, persistent bloating with no recent change in diet
• Intense or recurring abdominal pain
• Unexplained weight loss together with bloating
• Blood in your stools or a significant change in bowel habits
• Marked, persistent tiredness with chronic bloating
• Recurring bloating on just the right or left side

Quality from the field to your cup

For an anti-bloating tea to deliver a consistent experience, the plants themselves have to be up to the job. At Happy Detox Tea, our blends are co-developed with researchers from Xiamen Medical University, and our production facility is ISO 22000 certified. This certification guarantees traceability from the growing of the plants all the way to your cup — and it's why our customers have been able to count on consistent quality since 2015.

FAQ

How quickly does Zero Belly Tea work?

Many people notice more comfort after meals from the very first cup. For chronic bloating, allow 5 to 7 days of regular use (2–3 cups a day) to see the first lasting changes. Results vary from person to person.

How many cups of Zero Belly a day?

Ideally 2 to 3 cups a day, after each main meal. You can also have one mid-afternoon if you feel full.

Zero Belly or Teatox: which should I choose?

Zero Belly is a flexible, senna-free single anti-bloating tea, ideal for regular daily use or alongside an already healthy diet.

The Teatox is a structured morning + evening programme, more comprehensive, that supports drainage, digestion and transit, with plants traditionally used for the liver. Ideal for a 28-day "reset" when you feel more weighed down.

The two complement each other: many customers alternate — the Teatox once a quarter for a full programme, then Zero Belly as a maintenance routine the rest of the time.

Can I drink Zero Belly every day?

Yes. That's exactly what this tea is designed for: laxative-free, formulated for regular, long-term daily use. Many of our customers have had it in their routine for years.

Are there any contraindications to Zero Belly?

Zero Belly is not recommended during pregnancy or breastfeeding, for children under 12, in case of active liver or kidney disorders, or if you are on medication that requires close monitoring. Schisandra may interact with certain medications: ask your doctor if in doubt.

Can a bloated stomach show up on the scales?

Yes. Gas, water and digestive contents all have a weight (1 litre of water = 1 kg on the scales), so part of what the scales show can simply be bloating. That's why it's best not to weigh yourself when you feel bloated. Once you feel comfortable again, the scales naturally settle back to your usual balance.
