Most constipation is a passing problem. It turns serious when it comes with rectal bleeding, constant belly pain, vomiting, fever or unexplained weight loss. About 16 in 100 adults have it, usually from diet, fluids or routine. A sudden change in bowel habit that won’t settle, or being unable to pass stool or gas, may mean a blockage, a growth or inflammation.
According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Most constipation is harmless. It’s usually fibre, water and a rushed routine. What worries me is a sudden change, especially after fifty, or one that brings blood, weight loss or pain. Those patients need a proper look, not another laxative. Never assume.”

What Are the Red Flag Symptoms of Constipation?
Some symptoms don’t belong with ordinary constipation.
- Rectal bleeding: Blood on or in the stool shouldn’t be blamed on piles without a check. A growth has to be ruled out.
- Constant abdominal pain: Cramping that eases after passing stool is common. Pain that doesn’t let up is different.
- Vomiting and no gas: If nothing is moving either way, the bowel may be blocked. Seek emergency care.
- Weight loss or fever: Unexplained weight loss or a temperature points towards inflammation or a tumour.
A Colonoscopy lets the doctor see the bowel lining and take biopsies.
Which Serious Conditions Can Cause Constipation?
Several diseases narrow or slow the bowel.
- Colorectal polyps and cancer: A growth narrows the passage. Thin stools and incomplete emptying are clues.
- Bowel obstruction: Adhesions, hernias or tumours can block the gut. Bloating, pain and vomiting follow.
- Inflammatory bowel disease: Crohn’s and diverticular disease can scar the bowel. Some alternate with loose motions.
- Medical and drug causes: An underactive thyroid, diabetes, iron tablets and opioids all slow things down.
If constipation shows up alongside blood in stool, the cause needs to be found.
When Should You See a Doctor About Constipation?
Home measures work for most people. Book a review sooner if any of these fit.
- Over 50: A first-time change in bowel habit at this age is worth checking.
- Family history: A parent or sibling with colon or rectal cancer raises your risk.
- Nothing helps: Fibre, water and walking should work within weeks. If not, stop waiting.
- Anaemia: Low haemoglobin sometimes means slow bleeding you can’t see.
It also helps to know the colorectal cancer symptoms many people overlook.
Key Takeaways
Constipation is usually harmless. Bleeding, constant pain, vomiting, fever, weight loss or no passage of gas is not. A lasting new change in bowel habit, particularly after 50, needs investigation.
