Constipation, Diarrhoea and Bloating: When to See a Gastroenterologist

Written and reviewed by โ€” Gastroenterologist and liver specialist, Secunderabad

Short answer: Constipation, diarrhoea, and bloating often come from meals, a short infection, or irritable bowel syndrome. See a gastroenterologist if they last more than a few weeks, wake you at night, or come with blood, weight loss, anaemia, fever, or a family history of bowel disease. A one-day upset after outside food can be watched. A new pattern that stays needs a diagnosis, not a repeating course of antibiotics.

Constipation
Hard stools, straining, or a constant sense that the bowel has not emptied.
Diarrhoea
Loose stools. A short spell can be infection. A long spell needs a cause.
Bloating
A full, tight abdomen. Often diet or constipation. Sometimes a warning if it is new.
Book sooner if
Blood, weight loss, anaemia, fever, or symptoms that wake you at night.

These three complaints fill a gastroenterology clinic in Hyderabad, and they are not one disease. Constipation, diarrhoea, and bloating can travel together in irritable bowel syndrome, or they can each have a separate cause: a medicine, a thyroid change, an infection, or, less often, inflammation or a growth. The useful question is which pattern you have, and which extras make it unsafe to keep waiting.

When is constipation more than a low-fibre week?

A few hard days after travel, less water, or a painkiller course often improves with fluid, walking, and soluble fibre such as isabgol if your doctor agrees. Constipation that is new in later adult life, that needs increasing laxatives, or that comes with bleeding or a thinner stool, should be assessed. Iron tablets and some antidepressants slow the bowel. Mention them. Do not decide you have piles and skip the visit if the blood is mixed into the stool.

When should diarrhoea be checked?

  • Loose stools still present after a few weeks
  • Blood, black stools, or waking at night to pass stool
  • Fever, weight loss, or a family history of inflammatory bowel disease
  • Diarrhoea that starts after a course of antibiotics
  • Repeated antibiotic courses that never produced a diagnosis

A short illness with cramps after street food is different. Drink enough, use the oral fluids you would use for any dehydrating illness, and seek care if you cannot keep fluids down, you are elderly, or there is blood. Chronic diarrhoea is a different appointment, aimed at cause rather than another antibacterial strip.

What usually causes bloating, and what does not?

Bloating patterns that point in different directions
PatternOften considered
Tightness by evening, better after passing gas or stoolAir, meal size, constipation, or IBS
Bloating soon after milk or a very large wheat mealA personal food trigger, tested by a careful trial
New bloating, poor appetite, or weight lossNeeds examination. Do not label it gas.

The longer guide to living with IBS is the right next read if pain and a changed bowel habit have already been checked and no inflammatory disease was found. If you have not been checked, start with the symptom visit described on the constipation, diarrhoea and bloating page. Alarm features are listed together in the warning signs article.

For two weeks, note the time of each symptom, the stool type in plain words, and the previous meal. One change at a time. Five diet rules started on Monday will not tell you which rule helped.

Common questions

How long is too long for constipation?

There is no single correct number of stools per week. Constipation means hard stools, straining, or a sense of not emptying, and it bothers you. If that pattern is new and still present after a few weeks of fluid, fibre, and walking, or if it comes with bleeding or weight loss, book a visit.

When is diarrhoea no longer a stomach infection?

Loose stools for a day or two after travel or outside food are often infectious and settle. Diarrhoea that lasts beyond a few weeks, wakes you from sleep, or comes with blood, fever, or weight loss is not a routine infection and should not be treated with repeated antibiotics.

Why do I bloat every evening?

Evening bloating is often swallowed air, constipation, a large late meal, or a food that you personally ferment poorly, such as excess milk in some adults. New bloating with weight loss, vomiting, or a growing abdomen needs a doctor rather than another detox.

Should I stop wheat and milk immediately?

Only if a planned trial, or a test, shows that they are your trigger. Cutting large food groups on a guess can hide the real pattern and narrow your diet. Change one thing at a time and write down the result.

Who should I see in Secunderabad for these symptoms?

Dr Ajay Shesherao Shinde, a gastroenterologist at Medicover Hospital, Secunderabad, sorts constipation, diarrhoea, and bloating and orders tests only when the story needs them. Call +91 98901 05648.
