That uncomfortable, swollen belly after meals isn’t always just gas — it could be your body’s first warning sign of a serious digestive disorder. While occasional bloating is normal, chronic or severe bloating may indicate conditions ranging from food intolerances to life-threatening cancers.

In this eye-opening guide, Dr. Sandeep Pal, a top gastroenterologist in Chandigarh, reveals:
✔ 6 dangerous conditions masked as “simple bloating”
✔ Red-flag symptoms that demand immediate medical attention
✔ 10 must-know FAQs (from “Is bloating at night serious?” to “Can stress cause bloating?”)
✔ A 3-step self-check to assess your risk
When Bloating Isn’t Normal: 6 Serious Causes
1. Ovarian Cancer (The Silent Killer)
Why missed? Bloating is often dismissed as IBS or weight gain
Key signs:
Bloatedness lasting >3 weeks
Feeling full quickly (early satiety)
Pelvic discomfort
At risk: Women 50+ (or younger with family history)
2. Small Intestinal Bacterial Overgrowth (SIBO)
What happens: Gut bacteria migrate upward → ferment food prematurely
Unique clue: Bloating worsens with probiotics/fiber
Diagnosis: Hydrogen breath test
3. Gastroparesis (Stomach Paralysis)
Common in: Diabetics, post-viral patients
Tell-tale sign: Bloated 4+ hours after eating
Test: Gastric emptying study
4. Colon Cancer
Hidden symptom: Persistent bloating + pencil-thin stools
Emergency sign: Bloatedness + unintentional weight loss
5. Celiac Disease
Trigger: Gluten damages intestinal villi
Indicator: Bloating improves within days of gluten-free diet
6. Pancreatic Insufficiency
Why? Lack of digestive enzymes → food ferments in gut
Hint: Floating, foul-smelling stools
Dr. Pal’s Case:*A 38-year-old woman treated for “IBS” for years… later diagnosed with Stage 3 ovarian cancer after persistent bloating.*
Red Flags: When to Rush to a Doctor
🚨 Bloating + ANY of these:
Weight loss >5kg unintentionally
Blood in stool/vomit
Nighttime bloating (disrupting sleep)
Family history of ovarian/colon cancer
10 Critical FAQs Answered
1. “Is bloating after eating normal?”
Mild bloating <1 hour = normal>2 hours daily = investigate
2. “Does water intake worsen bloating?”
❌ No — dehydration actually slows digestion → more gas
3. “Can stress cause bloating?”
✅ Yes! Stress alters gut motility → “butterflies” turn to bloating
4. “Is nighttime bloating serious?”
Could indicate SIBO or gastroparesis (normal digestion slows at night)
5. “Do probiotics help or harm bloating?”
Depends:
Helps: If due to antibiotics/IBS
Worsens: If SIBO exists
6. “Can bloating be heart-related?”
Rarely — right heart failure causes fluid buildup in abdomen
7. “Why am I bloated despite eating healthy?”
High-FODMAP “health foods” (cauliflower, beans, apples) may be culprits
8. “Does bloating mean poor digestion?”
Often — could signal low stomach acid/enzymes
9. “Can thyroid issues cause bloating?”
✅ Hypothyroidism slows gut motility → constipation + bloating
10. “When should I get a scan for bloating?”
If:
Persistent >3 weeks
No relief from diet changes
3-Step Self Check for Serious Bloating
1. Track for 3 days:
Food intake
Bloating timing (after meals/night)
Stool changes
2. Try elimination diet:
Remove dairy/gluten × 1 week
3. Test at home:
SIBO: Try low-FODMAP diet (if helps → suspect SIBO)
Gastroparesis: Skip fiber × 2 days (if improves → suspect motility issue)
Still bloated? Time for medical tests.
Diagnostic Tests (Based on Suspicion)
Condition Key Tests SIBO Hydrogen breath test Ovarian cancer CA-125 + pelvic ultrasound Celiact TG-IgA blood test Gastroparesis 4-hour gastric emptying study
Cost in Chandigarh:
Ultrasound: ₹800–1,200
Breath test: ₹3,500
Colonoscopy: ₹4,000–6,000
Myths vs Facts
❌ “Bloating is always from gas.”✅ Fact: Fluid buildup (ascites) or tumors can also swell the belly.
❌ “Carbonated drinks cause chronic bloating.”✅ Fact: They may bloat temporarily but don’t cause long-term issues.
❌ “Ayurvedic herbs cure all bloating.”✅ Fact: Conditions like celiac/SIBO need medical treatment.
