Bloating — a feeling of fullness, tightness or swelling in the abdomen — is one of the most commonly reported digestive symptoms in the UK. It is frequently associated with IBS, functional dyspepsia, dietary factors and the gut-brain axis. While usually benign, persistent or worsening bloating should be assessed to rule out underlying conditions, and a range of dietary and complementary approaches can provide significant relief.
See therapies that may helpBloating refers to the subjective sensation of abdominal fullness, pressure or tightness. It is distinct from — but commonly accompanies — abdominal distension (visible increase in abdominal girth). The two do not always occur together: some people feel bloated without visible distension, and vice versa.
Common causes include: excess gas production from fermentation of undigested carbohydrates (high-FODMAP foods are particularly implicated); impaired gas transit through the gut; visceral hypersensitivity (heightened perception of normal gut distension — common in IBS); and swallowed air (aerophagia).
Hormonal fluctuations — particularly in the premenstrual phase — cause bloating in many women. Stress and anxiety exacerbate bloating through their effects on gut motility and visceral sensitivity.
Bloating typically involves:
Seek medical assessment if bloating is persistent and unexplained, associated with weight loss, changes in bowel habits, blood in the stool, or if you are a post-menopausal woman with new bloating — in this group, persistent bloating can occasionally indicate ovarian pathology.
Dietary approaches are often the most effective first line for bloating, with complementary therapies providing important additional support:
For most bloating, dietary assessment with a dietitian is a useful first step. If bloating is persistent, significantly affecting quality of life, or associated with other symptoms, GP assessment is appropriate. A therapist experienced in functional gut disorders can provide gut-directed hypnotherapy or CBT alongside dietary management.

Daily bloating is common and usually has identifiable causes including high-FODMAP foods, eating too quickly, stress, hormonal fluctuations, or IBS. A food and symptom diary can help identify patterns. If daily bloating is new, persistent and unexplained, a GP assessment is appropriate.
Yes — stress activates the gut-brain axis in ways that alter gut motility, increase visceral sensitivity (so normal amounts of gas feel more pronounced), and can cause aerophagia (swallowing air). Stress management is an important component of treatment for stress-related bloating.
Some probiotic strains have evidence for reducing bloating in IBS. Results vary by individual and strain. Probiotics are generally safe and worth trying, particularly Lactobacillus and Bifidobacterium strains shown in clinical trials to reduce IBS symptoms.
High-FODMAP foods are the most common dietary culprits — these include wheat, onions, garlic, legumes, apples, pears, stone fruits, and certain dairy products. Carbonated drinks, cruciferous vegetables (broccoli, cauliflower, cabbage) and sugar alcohols (sorbitol, mannitol) are also common triggers.
Most bloating is functional and benign. However, persistent unexplained bloating — particularly in post-menopausal women, or accompanied by weight loss, change in bowel habits or appetite loss — should be assessed by a GP. These can occasionally indicate conditions requiring investigation including ovarian pathology or gastrointestinal disease.
