Constipation
Constipation Evaluation and Treatment in Cypress and Katy, TX
Constipation is not only having fewer bowel movements. It may also involve hard or dry stools, painful bowel movements, repeated straining, a feeling that stool is stuck, or the sense that you did not empty completely. Occasional constipation often improves with changes in diet, activity, fluid intake, or bowel habits. However, persistent, recurring, or newly changed constipation may require evaluation by a gastroenterologist.
United Gastroenterology Associates evaluates constipation and related digestive symptoms for adults from Cypress, Katy, West Houston, and surrounding Greater Houston communities.

When Constipation May Need Urgent Medical Care
Seek prompt medical care when constipation occurs with any of the following:
- Rectal bleeding
- Blood in the stool
- Black or tarry stool
- Constant or severe abdominal pain
- A rapidly swollen abdomen
- Inability to pass gas
- Repeated vomiting
- Fever
- Unexplained weight loss
- Severe weakness, dizziness, or fainting
- New or rapidly worsening symptoms
Call 911 or go to the nearest emergency department for life-threatening symptoms. Do not use an online appointment form for an emergency.
NIDDK advises prompt medical evaluation when constipation is accompanied by rectal bleeding, blood in the stool, constant abdominal pain, inability to pass gas, vomiting, fever, or unintentional weight loss.
What Is Constipation?
Constipation describes bowel movements that are difficult, uncomfortable, incomplete, or less frequent than usual.
You may be constipated even when you have more than three bowel movements per week. Frequency is only one part of the condition. Stool consistency, straining, discomfort, blockage, and incomplete emptying are also important.
Your usual pattern matters. A new change from what is normal for you may need attention, particularly when it occurs with bleeding, anemia, abdominal pain, weight loss, or a family history of colorectal cancer.
Common Symptoms of Constipation
Constipation can cause one or several of the following:
- Fewer bowel movements than usual
- Hard, dry, or pellet-like stools
- Straining to pass stool
- Pain during a bowel movement
- Feeling that stool is stuck
- Feeling that the rectum is blocked
- Feeling that you did not empty completely
- Spending a long time on the toilet
- Abdominal bloating or pressure
- Abdominal cramping
- Excessive gas
- Rectal discomfort
- Hemorrhoid irritation caused by repeated straining
- Needing frequent laxatives, enemas, or suppositories
- Alternating constipation and diarrhea
Constipation may occur by itself or as part of another condition, such as irritable bowel syndrome with constipation, also called IBS-C.
When Should You See a Gastroenterologist for Constipation?
Schedule a medical evaluation when constipation:
- Does not improve with reasonable self-care
- Keeps returning
- Interferes with work, sleep, travel, or daily activities
- Requires frequent or increasing laxative use
- Represents a new change in bowel habits
- Alternates with diarrhea
- Causes ongoing abdominal pain or bloating
- Causes prolonged straining or incomplete emptying
- Makes you feel that stool is blocked
- Begins after starting a new medication
- Occurs with anemia, bleeding, or unexplained weight loss
- Occurs with a personal history of colon polyps
- Occurs with a family history of colorectal cancer
- Has not responded to previous treatment
A primary-care clinician can manage many uncomplicated cases. A gastroenterologist may be helpful when symptoms are persistent, the cause is uncertain, standard treatments have not worked, specialized bowel-function testing may be needed, or colonoscopy must be considered for a separate clinical reason.
Common Gastritis Symptoms
Upper stomach pain, burning stomach pain, sour stomach, nausea, bloating after eating, indigestion, feeling full quickly, and loss of appetite are common signs of gastritis.
What Causes Gastritis?
Common causes include H. pylori infection, frequent NSAID pain relievers, alcohol, bile reflux, and autoimmune gastritis, among other digestive conditions.
When to See a GI Doctor
See a gastroenterologist if symptoms are persistent, worsening, or not improving, or if you have a history of ulcers or H. pylori or long-term NSAID use with stomach pain. Need Consultation!

Understanding the Causes
What Causes Constipation?
Constipation often has more than one contributing factor. A proper evaluation looks beyond fiber intake alone.
Diet, fluid, activity, and daily routine
Common contributing factors include:
- Not eating enough fiber
- Not drinking enough fluid for your individual health needs
- Low physical activity
- Ignoring the urge to have a bowel movement
- Travel
- Illness
- Changes in eating patterns
- Changes in work or sleep schedules
- Spending insufficient time in the bathroom
- Regularly delaying bowel movements
Medicines and supplements
Some prescription medicines, over-the-counter products, and supplements may contribute to constipation.
Examples may include:
- Opioid pain medicines
- Iron supplements
- Certain antacids
- Some antidepressants
- Anticholinergic medicines
- Some blood-pressure medicines
- Certain allergy medicines
- Some medicines used for neurologic or psychiatric conditions
Do not stop or change a prescribed medicine without speaking with the clinician who prescribed it.
Bring a complete list of your medicines, vitamins, supplements, laxatives, teas, and other products to your appointment.
Digestive and pelvic-floor conditions
Constipation may be related to:
- Irritable bowel syndrome with constipation
- Slow movement of stool through the colon
- Pelvic-floor dysfunction
- Difficulty coordinating the muscles used for bowel emptying
- Anal or rectal narrowing
- Rectocele
- Rectal prolapse
- Inflammation
- Diverticular disease
- Previous pelvic or abdominal surgery
- Less commonly, an intestinal blockage or tumor
Medical and neurologic conditions
Constipation may also be associated with:
- Diabetes
- Hypothyroidism
- Celiac disease
- Pregnancy
- Parkinson’s disease
- Multiple sclerosis
- Spinal cord disease or injury
- Other neurologic conditions
- Changes associated with aging
Testing should be selected according to the patient’s symptoms, history, examination, and response to treatment rather than performed routinely for every person.
Types of Chronic Constipation
Understanding the type of constipation can help guide treatment.
Normal-transit constipation
With normal-transit constipation, stool may move through the colon at a generally expected rate, but bowel movements still feel difficult, hard, painful, or incomplete.
Slow-transit constipation
With slow-transit constipation, stool moves more slowly through the colon.
Possible symptoms include:
- Infrequent bowel movements
- Persistent bloating
- Abdominal discomfort
- Limited response to basic treatments
- Reduced natural urge to have a bowel movement
Pelvic-floor or defecatory dysfunction
The muscles used to empty the rectum may not relax and coordinate correctly.
Possible signs include:
- Prolonged straining
- Feeling blocked
- Feeling incompletely emptied
- Having a strong urge but being unable to pass stool
- Needing unusual positioning or manual assistance
- Repeated failure of laxatives to solve the problem
When pelvic-floor dysfunction is present, simply adding more laxatives may not address the underlying problem.
IBS with constipation
IBS-C commonly involves recurrent abdominal pain associated with bowel movements and changes in stool frequency or form.
Treatment for IBS-C may differ from treatment for chronic constipation without recurring abdominal pain.
Medication-induced constipation
When a medicine contributes to constipation, treatment may require:
- Reviewing the medication
- Adjusting the dose under prescriber supervision
- Changing to another medicine when medically appropriate
- Developing a preventive bowel plan
- Using treatment specifically designed for medication-related constipation
Opioid-induced constipation may require a different approach from constipation caused by diet, routine, or pelvic-floor dysfunction.
How Is Constipation Evaluated?
Evaluation usually begins with a detailed medical history and a focused physical examination.
The purpose is to understand your bowel pattern, identify contributing factors, look for warning signs, and avoid unnecessary testing.
Questions your gastroenterologist may ask
Your clinician may ask:
- How often do you have bowel movements?
- How does this compare with your normal pattern?
- Are your stools hard, dry, or pellet-like?
- Do you strain?
- Do you feel blocked?
- Do you feel incompletely emptied?
- How long have the symptoms been present?
- Have the symptoms changed recently?
- What treatments have you tried?
- Do you have abdominal pain or bloating?
- Have you noticed blood in the stool?
- Have you lost weight without trying?
- What medicines and supplements do you take?
- Have you had abdominal or pelvic surgery?
- Have you previously had colonoscopy?
- Is there a family history of colon polyps or colorectal cancer?
Physical examination
Depending on the situation, the examination may include:
- Checking the abdomen for tenderness or swelling
- Listening to bowel sounds
- Looking for signs of dehydration
- A rectal examination
- Evaluating the pelvic-floor muscles
- Looking for hemorrhoids, fissures, narrowing, or other anorectal problems
Tests that may be considered
Not every patient needs testing. When clinically appropriate, evaluation may include:
- Blood tests
- Thyroid testing
- Testing for anemia
- Celiac disease testing
- Stool testing
- Colonoscopy
- Flexible sigmoidoscopy
- Colonic-transit testing
- Anorectal manometry
- Balloon-expulsion testing
- Defecography
- Other imaging in selected cases
Medical history, family history, physical examination, and selected laboratory or imaging tests may be used to identify the cause of constipation.

Helping You Feel Lighter Every Day.
Does Everyone With Constipation Need a Colonoscopy?
Don't Let Constipation Control Your Life.
No. Constipation by itself does not automatically require colonoscopy.
A gastroenterologist may recommend colonoscopy based on factors such as:
- Whether colorectal screening is due
- Rectal bleeding
- Blood in the stool
- Iron-deficiency anemia
- Unexplained weight loss
- A new change in bowel habits
- Abnormal examination findings
- A history of colon polyps
- A family history of colorectal cancer
- Other concerning symptoms
Patients who are due for colorectal cancer screening may need colonoscopy independently of their constipation.
How Is Constipation Treated?
Treatment depends on:
- The suspected cause
- How long symptoms have been present
- Stool consistency
- Bowel frequency
- Abdominal pain
- Other medical conditions
- Current medicines
- Previous treatment response
- Whether pelvic-floor dysfunction is present
The goal is not simply to produce one bowel movement. The goal is to create a safe, sustainable plan that improves stool consistency, ease of passage, bowel regularity, and quality of life.
Increase fiber gradually
Fiber can help increase stool bulk and improve stool consistency.
Sources of dietary fiber include:
- Beans
- Lentils
- Whole grains
- Vegetables
- Fruit
- Nuts
- Seeds
Adults generally need approximately 22 to 34 grams of fiber per day, depending on age and sex. Increase fiber gradually because a sudden increase may worsen bloating, gas, or abdominal discomfort.
Fiber is not appropriate as the only treatment for every type of constipation. Patients with severe bloating, suspected obstruction, certain pelvic-floor problems, or slow-transit constipation may need a more individualized approach.
Drink enough fluid
Adequate fluid can help fiber work more effectively and may help when a person is dehydrated.
Drinking excessive amounts of water is not a universal cure for constipation.
Ask your clinician about a safe fluid target if you have:
- Heart failure
- Kidney disease
- Liver disease
- A medical reason to restrict fluid
Improve bowel habits
Helpful habits may include:
- Responding to the urge to have a bowel movement
- Avoiding unnecessary delay
- Allowing unhurried bathroom time
- Trying to use the bathroom after a meal, often after breakfast
- Using a footstool to improve positioning
- Keeping a bowel diary
- Staying physically active as your health allows
NIDDK notes that regular physical activity, consistent bowel training, using the bathroom when the urge occurs, and allowing sufficient time may help relieve constipation.
Over-the-counter treatments
Depending on your health history and symptoms, a clinician may recommend:
- A fiber supplement
- An osmotic laxative
- A stool-softening strategy
- A stimulant laxative
- A short-term rescue treatment
- Another over-the-counter product
These products work in different ways.
Possible side effects may include:
- Bloating
- Gas
- Cramping
- Diarrhea
- Dehydration
- Electrolyte changes
- Medication interactions
Do not assume that a product is safe simply because it is labeled “natural.”
Frequent, increasing, or long-term laxative use should be reviewed with a healthcare professional.
Prescription constipation treatment
Prescription treatment may be considered when appropriate lifestyle measures and over-the-counter options have not provided adequate relief.
The choice of medication depends on:
- Whether the diagnosis is chronic idiopathic constipation or IBS-C
- Other health conditions
- Kidney function
- Previous treatment response
- Possible adverse effects
- Cost
- Insurance coverage
- Patient preferences
Joint AGA–ACG guidance includes evidence-based prescription and nonprescription options for adults with chronic idiopathic constipation, particularly after appropriate over-the-counter treatments have not worked.
Pelvic-floor biofeedback
When testing identifies a defecatory disorder, pelvic-floor retraining with biofeedback may be more useful than repeatedly adding laxatives.
Biofeedback helps patients learn to coordinate the muscles and nerves involved in bowel emptying.
AGA guidance recommends anorectal testing for selected patients who do not respond to basic treatment and recommends pelvic-floor biofeedback rather than laxatives alone for defecatory disorders.
Treating an underlying cause
Treatment may involve:
- Addressing hypothyroidism or another medical condition
- Reviewing a contributing medication
- Treating IBS-C
- Managing opioid-induced constipation
- Treating a structural problem
- Addressing pelvic-floor dysfunction
- Improving diet and routine
- Updating colorectal cancer screening
Surgery is uncommon and is generally reserved for carefully selected patients after thorough specialist evaluation.

How to Prepare for a Constipation Appointment
Bring or record the following information:
- How often you have bowel movements
- What your stool usually looks like
- Whether you strain

Your Questions, Answered
Frequently Asked Questions
How many days without a bowel movement is considered constipation?
There is no single number that applies to everyone.
Fewer than three bowel movements per week is one common sign, but hard stools, painful passage, repeated straining, blockage, and incomplete emptying also matter.
A change from your usual bowel pattern is important even when you have more than three bowel movements per week.
When should I worry about constipation?
Schedule a medical evaluation when constipation persists despite self-care, keeps returning, or represents a new change.
Seek prompt care when constipation occurs with rectal bleeding, blood in the stool, severe or constant abdominal pain, inability to pass gas, vomiting, fever, or unexplained weight loss.
What type of doctor treats chronic constipation?
Primary-care clinicians treat many uncomplicated cases.
A gastroenterologist evaluates persistent, recurring, complicated, or treatment-resistant constipation and can arrange specialized bowel-function testing when appropriate.
Is constipation always caused by not eating enough fiber?
No.
Low fiber intake can contribute, but constipation may also be related to medicines, dehydration, IBS-C, slow movement through the colon, pelvic-floor dysfunction, thyroid disease, diabetes, neurologic conditions, structural problems, or changes in daily routine.
Does drinking more water cure constipation?
Correcting dehydration may help, especially when fiber intake is increased.
Drinking excessive amounts of water is not a universal cure. Some patients also need to limit fluids because of heart, kidney, or liver conditions.
Why is fiber making my constipation or bloating worse?
A rapid increase in fiber can cause gas, bloating, or discomfort.
Fiber may also be insufficient by itself when constipation involves slow transit, pelvic-floor dysfunction, medication effects, or another underlying condition.
Speak with a clinician before continuing to increase fiber when symptoms are worsening.
Do I need a colonoscopy for constipation?
Not automatically.
The decision depends on your age and screening status, bleeding, anemia, weight loss, family history, a new bowel-habit change, abnormal examination findings, and other clinical concerns.
What tests check for pelvic-floor constipation?
Testing may include anorectal manometry, balloon-expulsion testing, and sometimes defecography.
These tests help evaluate how the rectum and pelvic-floor muscles coordinate during bowel emptying.
Can medicines cause constipation?
Yes.
Opioid pain medicines, iron, certain antacids, some antidepressants, anticholinergic drugs, and other medicines may contribute.
Do not stop a prescribed medicine without speaking with the prescribing clinician.
