Constant Bloating: Why It Won't Go Away and What to Do

Why do I feel bloated all the time?

Most people experience bloating from time to time, often after eating quickly, drinking fizzy drinks or having a large meal. This usually improves as digestion continues.

Constant or recurring bloating is different. If it happens most days, lasts for weeks, or keeps coming back without an obvious trigger, it may be linked to constipation, food intolerance, IBS, hormonal changes, stress or another digestive issue. Some people describe this as a heavy, full or pressured feeling in the stomach, especially when gas, food or stool is moving slowly through the digestive tract.

What causes constant bloating?

Constant bloating is not a condition in itself. It is a symptom that can have many possible causes. The most common include trapped gas, constipation, food intolerances, IBS, SIBO, stress, hormonal changes and, in some people, changes in the gut microbiome.

The right next step depends on the likely cause. For example, bloating linked to constipation may improve with bowel regularity, while bloating linked to food intolerance, stress or SIBO may need a different approach.

Diet and food intolerances

Excess gas is one of the most common reasons for bloating. It can happen after eating gas-producing foods such as beans, lentils, cabbage, onions or broccoli, or after drinking fizzy drinks.

Some carbohydrates, including lactose, fructose and wheat-based carbohydrates, can be difficult for some people to digest. When these carbohydrates are not fully absorbed, gut bacteria can ferment them, producing gas and bloating.

Gut microbiome imbalance

The gut microbiome helps break down certain foods and produces gases as part of normal fermentation. In some people, changes in gut bacteria may contribute to bloating, especially in functional bloating, IBS or other disorders of gut-brain interaction. However, the microbiome is usually one factor among many, not the only cause.

SIBO

SIBO, or small intestinal bacterial overgrowth, happens when excess bacteria are present in the small intestine. It can cause bloating, gas, abdominal discomfort and changes in bowel habits. Because these symptoms overlap with many other digestive issues, SIBO usually needs proper assessment rather than self-diagnosis.

Stress and the gut-brain connection

Stress can affect digestion through the gut-brain connection, the two-way communication network between the brain and the gut. In some people, stress can change gut movement, increase gut sensitivity and make bloating feel worse, even when there is no obvious structural problem.

Hormones

Hormonal changes can also affect bloating. Many people notice bloating before or during their period, during pregnancy or around perimenopause. Hormone shifts may affect fluid retention, gut movement and how full or swollen the abdomen feels.

Constipation

Constipation is another common cause of persistent bloating. When stool builds up in the bowel, gas can become trapped, making the abdomen feel swollen and uncomfortable. Improving bowel regularity often helps reduce bloating.

When should you worry about bloating?

Bloating is often linked to diet, constipation, hormones or other digestive factors, but it is worth getting checked if it is persistent, getting worse, or happening alongside other concerning symptoms.

You should speak to a healthcare professional if bloating comes with:

• persistent abdominal pain
• vomiting
• fever
• unexplained weight loss
• blood in your stool
• ongoing constipation or diarrhoea
• an abdominal lump or swelling
• difficulty passing stool or gas

In some cases, persistent bloating can be linked to an underlying medical condition, including inflammatory bowel disease or, more rarely, conditions such as ovarian or bowel cancer. That does not mean bloating is usually a sign of something serious, but it does mean ongoing or unexplained symptoms should not be ignored.

How do you get rid of constant bloating?

The best way to reduce constant bloating depends on what is causing it. For many people, simple changes can help, especially if bloating is linked to eating habits, constipation or trapped gas.

You may find it helpful to:

• exercise regularly, even a daily walk can support digestion
• drink enough water throughout the day
• eat smaller, more regular meals
• chew slowly and avoid swallowing excess air
• reduce fizzy drinks if they make symptoms worse
• limit foods that consistently trigger bloating
• increase soluble fibre gradually if constipation is contributing

Some people may also benefit from over-the-counter options, such as simeticone for trapped gas or laxatives for constipation. These should be used according to the advice of a pharmacist or healthcare professional.

Because many digestive issues share similar symptoms, persistent bloating can be difficult to understand from symptoms alone. If bloating continues, further assessment or testing may help identify possible contributing factors, such as food intolerances, constipation, SIBO, IBS or changes in the gut microbiome.
