Reasons for lower stomach bloating

A lower abdomen that feels tight after meals may reflect gas, swallowed air, or fermentation of certain carbohydrates. Constipation can leave stool in the bowel longer and increase pressure. Irritable Bowel Syndrome can present with bloating, discomfort, and changed stool habits. Food Intolerance or Lactose Intolerance may produce symptoms after a repeatable food exposure. Coeliac Disease can cause longer-lasting digestive symptoms. Giardiasis should be considered when bloating occurs with ongoing diarrhoea after unsafe food or water exposure. Helicobacter Pylori Infection more often affects the upper digestive tract, but a clinician may consider it with bloating and indigestion. Bloating alone cannot identify the cause.

Record when symptoms begin, what you ate, your stool pattern, pain location, and any travel or sick contacts. Eat at a relaxed pace and keep portions moderate while observing the pattern. Gentle activity and adequate fluids may help if constipation contributes. Do not start a restrictive elimination diet without advice, because removing several food groups can reduce nutrition and hide useful clues. A doctor can review the timeline, examine you, and decide whether testing is appropriate.

Get urgent help for sudden severe pain, a rigid or rapidly enlarging abdomen, repeated vomiting, inability to pass stool or gas, fainting, or breathing difficulty. Arrange prompt review for blood in stool, fever, persistent watery diarrhoea, unintentional weight change, or steadily worsening bloating. The urgency comes from these accompanying features, not from bloating by itself.

What causes fit the timing of my bloating? Could constipation or intolerance be involved? Do I need testing for infection or coeliac disease? What should I record before follow-up?
