Bloating, nausea and fatigue

A stomach or bowel infection can combine nausea, tiredness, appetite change and abdominal fullness. Food Intolerance or Lactose Intolerance may cause symptoms after particular foods, while Coeliac Disease can cause continuing digestive complaints. Helicobacter Pylori Infection may irritate the stomach. Irritable Bowel Syndrome can link bloating with bowel habit changes, although fatigue or nausea may have a separate cause. Symptoms alone cannot confirm which explanation applies.

Rest, take frequent small sips, and eat little and often as nausea eases. Keep notes on food, bowel movements, pain, temperature, sleep, stress, periods if relevant, and any new medicine. Avoid alcohol and foods that repeatedly trigger symptoms. Do not rely on prolonged elimination diets without professional guidance; Nutrition Counselling may support a nutritionally adequate plan. Book a medical review if symptoms continue, recur or reduce your intake.

Seek urgent care for severe or one-sided worsening pain, repeated vomiting, a swollen hard abdomen, fainting, confusion, blood in vomit or stool, black stools, high fever with weakness, yellowing of the skin or eyes, or very little urine. Prompt review is needed when fatigue is worsening, nausea prevents drinking, or weight is falling without an intended change.

Ask what the symptom sequence suggests, whether medicines or diet could contribute, and whether tests for infection, anaemia or digestive conditions are appropriate. Clarify how much fluid to take and when to seek same-day help.
