Bloating, Abdominal Swelling & “Pregnant Look”: When to See a Doctor

Immediate Steps

1. Schedule a medical visit – Do not self‑diagnose.
2. Track symptoms – Timing, triggers, menstrual cycle, bowel habits, weight changes.
3. Bring medication list & history – Including supplements.

Common Causes of Visible Abdominal Distension

• Menstrual cycle – Premenstrual bloating.
• Pregnancy – Test if sexually active; ultrasound/blood hCG confirms.
• Digestive disorders – IBS, constipation, SIBO, food intolerances (lactose, fructose, gluten).
• Ovarian cyst – Can cause unilateral fullness.
• Uterine fibroids/adenomyosis – Enlarged uterus mimics pregnancy.
• Ascites – Fluid from liver disease, heart failure, malignancy.
• Rare: tumors – Ovarian, peritoneal, mesenteric.

Red Flags (Seek Urgent Care)

• Severe pain, fever, vomiting
• Shortness of breath
• Rapid abdominal enlargement
• Blood in stool or urine

Diagnosis typically involves exam, blood work, ultrasound ± CT. Treatment targets the underlying cause.
