Most abdominal bloating lasts a few hours to a couple of days and eases once you pass gas or have a bowel movement.
The timing depends on the cause. Bloating from a big meal, carbonated drinks, swallowed air, beans, or high fiber foods usually settles the same day, while bloating from constipation lasts until stools start moving again. Bloating linked to your period tends to run a few days and fades once bleeding starts. Lactose intolerance, celiac disease, and irritable bowel syndrome cause bloating that keeps coming back over weeks or months until the cause is managed. Walking after meals, eating more slowly, cutting back on fizzy drinks, and staying well hydrated often shorten an episode.

Common questions
How long does Abdominal bloating last?
Bloating that follows a large meal, carbonated drinks, or a gassy food usually settles within a few hours to a day. Bloating tied to constipation clears once stools move again, often in one to three days. Bloating around your period typically lasts a few days. When bloating comes from lactose intolerance, celiac disease, or irritable bowel syndrome, it repeats over weeks or months and improves only when the underlying cause is treated. Get medical care if bloating lasts more than two weeks, keeps getting worse, or comes with weight loss, vomiting, blood in your stool, fever, or a belly that stays swollen and firm.
