What is constipation?
Constipation is a common digestive problem characterized by infrequent bowel movements, difficulty passing stool, or a feeling of incomplete evacuation.
People often describe constipation as “not going to the bathroom every day,” but normal bowel frequency can vary. What matters most is whether bowel movements are difficult, painful, or significantly less frequent than usual.
In many cases, constipation is related to lifestyle factors such as low fiber intake, dehydration, lack of physical activity, and routine changes. However, it can also be a sign of underlying medical conditions.
Is constipation a condition or just a symptom?
Constipation can be both.
It may occur as:
-
a symptom, caused by another condition (such as hypothyroidism, diabetes, neurological disorders, or side effects of medications)
-
a primary condition, when constipation persists without an identifiable cause, often called functional constipation or chronic constipation
That is why persistent constipation should not be ignored, especially if it is new or worsening.
How constipation is defined (common clinical criteria)
Constipation is often suspected when a person experiences one or more of the following:
-
fewer than 3 bowel movements per week
-
hard or dry stools
-
excessive straining during bowel movements
-
pain while passing stool
-
a sensation of incomplete emptying
-
a feeling of blockage in the rectum
-
frequent need for laxatives
If these symptoms persist for several weeks, medical evaluation may be helpful.
Main causes and risk factors
Constipation has multiple possible causes. The most common include:
Lifestyle-related causes
-
low fiber diet
-
inadequate fluid intake
-
sedentary lifestyle
-
ignoring the urge to have a bowel movement
-
stress and irregular routine
-
travel and schedule disruption
Hormonal and metabolic conditions
-
hypothyroidism
-
diabetes
-
pregnancy-related hormonal changes
Gastrointestinal causes
-
irritable bowel syndrome (IBS-C)
-
slow intestinal transit
-
pelvic floor dysfunction
Neurological causes
-
Parkinson’s disease
-
multiple sclerosis
-
spinal cord injury
Less common but serious causes
-
colorectal cancer
-
bowel obstruction or strictures
-
inflammatory bowel disease in some cases
Constipation in children, adults, and older adults
Constipation may look different depending on age.
In children
Constipation may occur due to:
-
low fiber intake
-
dehydration
-
fear of pain during bowel movements
-
toilet training issues
-
routine changes
In adults
The most common causes include:
-
poor dietary habits
-
stress and sedentary lifestyle
-
medication side effects
In older adults
Constipation becomes more frequent with age due to:
-
reduced mobility
-
lower fluid intake
-
multiple medications
-
slower intestinal motility
Constipation during pregnancy
Constipation is very common during pregnancy and may be caused by:
-
hormonal changes that slow digestion
-
pressure from the growing uterus
-
iron supplementation
-
reduced activity
Dietary changes and hydration are usually the first approach. Medication should be used only with professional guidance.
Medications that may cause constipation
Many medications can contribute to constipation, including:
-
opioid pain medications
-
antidepressants and anti-anxiety medications
-
iron supplements
-
calcium supplements
-
certain antacids
-
diuretics (due to dehydration)
-
some blood pressure medications
If constipation begins after starting a new medication, discuss it with a healthcare professional.
Diagnosis and recommended tests
Diagnosis is usually based on medical history and physical examination.
A healthcare provider may ask about:
-
bowel movement frequency and stool consistency
-
diet and fluid intake
-
physical activity
-
medication use
-
presence of blood, pain, or weight loss
If needed, tests may include:
-
blood tests (thyroid function, glucose levels, electrolytes)
-
colonoscopy (especially for older adults or warning signs)
-
imaging tests in suspected obstruction
-
specialized motility tests for chronic cases
Possible complications
Long-term constipation may lead to:
-
hemorrhoids
-
anal fissures
-
abdominal discomfort and bloating
-
fecal impaction
-
rectal prolapse (in severe cases)
-
reduced quality of life
Inappropriate long-term use of certain laxatives may also cause dependency or electrolyte imbalance.
Treatment: diet and lifestyle changes
Most constipation cases improve with lifestyle measures.
Key strategies include:
Increase dietary fiber
Good sources include:
-
fruits (especially prunes, pears, apples)
-
vegetables and legumes
-
whole grains
-
oats, flaxseed, chia
Drink enough fluids
Fiber works best with adequate hydration.
Exercise regularly
Physical activity helps stimulate bowel movements.
Do not ignore the urge to go
Delaying bowel movements regularly can worsen constipation.
Build a routine
Many people benefit from trying to use the bathroom at the same time daily, especially after meals.
Treatment: laxatives and medications
When lifestyle changes are not enough, medications may be recommended depending on severity.
Common options include:
-
bulk-forming agents (fiber supplements such as psyllium)
-
osmotic laxatives (such as polyethylene glycol or lactulose)
-
stimulant laxatives (short-term use only, when appropriate)
-
suppositories or enemas in specific situations
⚠️ Regular use of stimulant laxatives without medical guidance is not recommended.
Do probiotics help?
Probiotics may help some individuals, especially those with IBS-related constipation or gut microbiome imbalance.
However, results vary, and probiotics should not replace the main treatment approach, which includes fiber, hydration, and physical activity.
When to see a doctor (warning signs)
Seek medical evaluation if constipation is accompanied by:
-
blood in the stool
-
unexplained weight loss
-
anemia
-
severe or persistent abdominal pain
-
new constipation in older adults
-
persistent vomiting
-
fever
-
major changes in bowel habits
-
family history of colorectal cancer
-
constipation that does not improve with lifestyle measures
These symptoms may suggest an underlying condition requiring further investigation.

Quick FAQ
Is constipation normal?
Occasional constipation is common, but persistent symptoms should be evaluated.
What foods help relieve constipation?
Fiber-rich foods like prunes, oats, fruits, vegetables, and legumes are commonly helpful.
Can stress cause constipation?
Yes. Stress can affect gut motility and bowel habits.
Can constipation cause hemorrhoids?
