Who this is for
If you pass stool fewer than three times a week, strain, feel unfinished afterwards or see hard pellet-like stools, this page is for you. It is general guidance for adults with occasional or mild constipation. Learn more about the symptom on our constipation page and use the Bristol stool chart to describe what you see.
The idea behind it
Stool is mostly water, undigested plant fibre and bacteria. When there is too little fibre or fluid, or movement through the gut is slow, stool becomes hard and difficult to pass. Different fibres do different jobs. Insoluble fibre, such as wheat bran, adds bulk. Soluble fibre, such as isabgol (psyllium) and oats, holds water and makes stool softer. Bacteria ferment some fibres and produce short-chain fatty acids, which the gut lining uses. See fibre types and gut bacteria. The key is to add fibre slowly, with water, plus movement and a regular toilet routine.
What to eat
- Whole grains: whole wheat chapati, jowar, bajra and ragi rotis, brown rice, daliya, oats.
- Dals and legumes such as moong, masoor, whole moong sprouts, chana and rajma, in portions you tolerate.
- Vegetables with skin and fibre: bottle gourd, ridge gourd, spinach, methi leaves, carrots, beans, peas, cabbage and beetroot.
- Fruit: ripe papaya, guava with seeds, pears, oranges, apples with skin, soaked anjeer (figs), prunes and raisins.
- Seeds: a teaspoon of ground flaxseed (alsi) or soaked chia seeds, introduced gradually.
- Isabgol (psyllium husk) one teaspoon in a glass of water at night is a familiar remedy, but it needs plenty of fluid to be taken with it.
- Curd and chaas for fluid and live cultures.
- Warm water in the morning, and ghee in a small amount, a traditional habit some find helpful.
What to limit or go slowly with
White bread, maida-based items (naan, kulcha, biscuits), refined rice in large portions, cheese, fried snacks and heavy sweets give little fibre. Too much tea and coffee can dry out some people, while for others coffee helps the morning bowel. Do not jump from low to very high fibre in a day, because gas and cramps follow. Increase by a small amount every few days. If fibre makes bloating worse, slow down and see the bloating diet.

Habits that help
- Drink water through the day. Pale yellow urine is a rough guide.
- Keep a routine: sit on the toilet at the same time daily, ideally 20 to 30 minutes after breakfast, without straining or scrolling for long.
- A footstool under your feet raises your knees above your hips, which many people find easier.
- Walk 20 to 30 minutes most days. Movement helps the bowel move.
- Do not ignore the urge to go.
- Chew thoroughly, and eat breakfast, as the morning meal often triggers the bowel reflex.
- Cook vegetables lightly so you keep fibre but soften it.
A morning routine often works better than any single food. A glass of warm water on waking, a breakfast with some fibre and a little fat, and ten unhurried minutes in the bathroom afterwards give the bowel’s natural reflex a chance. If you travel, fasting during festivals or changing shift hours often upsets this rhythm, so carry some fruit, nuts and a water bottle, and get back to your routine as soon as you can.
When to see a doctor first
See a doctor if constipation is new after the age of 45 to 50, if you notice blood in stool or black stools, unexplained weight loss, severe pain, persistent vomiting, a swollen abdomen, anaemia, or a family history of bowel cancer. Constipation that alternates with diarrhoea, or does not improve over a few weeks of sensible changes, also deserves a check. Some medicines (iron, certain painkillers, some antidepressants) and thyroid problems can cause it.
Common questions
How much fibre should I aim for?
Guidelines for adults are generally in the range of 25 to 30 grams a day, though needs vary. Build up gradually rather than counting numbers on day one.
Is isabgol safe to take every day?
Many people use it regularly. Take it with a full glass of water, and keep it a couple of hours apart from medicines unless your doctor says otherwise.
Will probiotics help?
Some studies suggest certain strains may help stool frequency, but results differ. See probiotics vs prebiotics vs synbiotics.
I eat fibre and I’m still constipated. Why?
Without enough fluid, or when the pelvic floor is not relaxing properly, extra fibre can make things worse. A doctor or dietitian can look into this.
