Constipation chronique
الإمساك المزمن
Infrequent or difficult bowel movements persisting over weeks or longer, most often related to diet, fluid intake, physical activity, or certain medications, though it can also signal an underlying digestive or metabolic condition. Usually manageable with fiber, hydration, and lifestyle changes; persistent cases warrant medical evaluation.

Réponse rapide
Constipation means passing stools less often than usual, or with difficulty — hard, dry or lumpy stools, straining, or feeling you haven't emptied fully. It is chronic when it persists for weeks or longer.
It is very common and most often related to low fibre or fluids, low activity, ignoring the urge to go, certain medicines, or changes in routine.
Fibre, fluids, activity and a regular toilet routine help most people. See a doctor if it is persistent, new in later life, or comes with blood, weight loss, severe pain or a change in bowel habit that lasts.
Symptômes

Comment le diagnostic est-il posé ?
Doctors usually diagnose constipation from your history and examination, and use tests when there are warning signs or it doesn't respond to treatment.
History and examination
Stool pattern, diet, medicines and warning signs; abdominal and rectal examination.
Blood tests
For example thyroid function, blood count and calcium, if a medical cause is suspected.
Colonoscopy or imaging
For warning signs such as bleeding, anaemia, weight loss or new symptoms in older adults.
Specialist bowel function tests
For persistent, difficult-to-treat cases.
Traitement
Most constipation improves with lifestyle changes; laxatives are used if needed. The choice depends on the cause and the person and should be guided by a doctor or pharmacist.
More fibre and fluids
Gradually increase fruit, vegetables, whole grains and pulses, with enough water.
Regular activity
A regular toilet routine
Try to go after meals and don't ignore the urge; a footstool can help position.
Laxatives
Different types work in different ways; use as advised and avoid long-term use without medical guidance.
Treating a cause
Reviewing medicines or treating a related condition.
Increase fibre gradually — too much too fast can cause bloating and gas.
