ConstipationAlso known as Costiveness, Dyschezia
Constipation is a common health problem that causes difficulty in passing stools and emptying the bowels. Almost everyone goes through constipation at some point in their lives. While constipation is uncomfortable, it is usually considered a symptom rather than a disease in itself. The various causes of constipation include diet that is not sufficient in fiber content, inadequate fluid intake, sedentary lifestyle, stress or sometimes an effect of some underlying medical condition of intake of specific medicines.
Prevention of constipation is centred around change in dietary and lifestyle habits. One should eat a high fiber diet comprising fruits, vegetables, legumes and whole grains. Restrict foods such as processed and packaged foods, milk and meat products.
Maintaining optimal fluid intake along with restricting intake of alcohol and caffeine in the form of coffee and soft drinks can also help in preventing constipation. Exercise regularly, do not delay the urge to pass stools and try to manage your stress levels.
Along with these changes, treatment of constipation involves many home remedies and use of over the counter laxatives. If relief from constipation is still not achieved, or in case of problems like pain while passing stools or rectal bleeding, it is always better to consult a doctor as long term use of laxatives or chronic constipation can lead to several other complications.

Symptoms Of Constipation
The symptoms of constipation include:
Reduced bowel movement of less than three times a week
Passing hard and lumpy stools
Straining while passing stools
Feeling of fullness, even after passing stools
Feeling of not able to completely evacuate the stools from the rectum
Feeling of a blockage in the rectum that prevents passing of stools
Some people may even need digital evacuation of stools
Causes Of Constipation
Some of the common cases of constipation include:
1. Poor dietary habits
One of the common causes of constipation is poor dietary habits that can affect bowel movements. If your diet fails to include foods rich in fibre such as fruits and vegetables in the right quantity, it can affect digestion and passing of stools. This is because fibre acts as a natural laxative, which holds water in the stool, increases its bulk and makes it easy to pass.
2. Insufficient fluid intake
Lack of sufficient water in the body can lead to dehydration is another factor that can cause constipation. When you suffer from dehydration, the body tries to conserve water by removing water from the stools. As a result, the stools contain less amount of water, which makes it harder to pass them from rectum.
3. Use of certain medicines
Constipation can be caused as a side-effect of certain medicines such as iron salts, opioids, sedatives, over the counter antacids and some of the drugs used to lower blood pressure. So if you are taking any of these medicines, then do consult your doctor. He may either change the dosage of the medicines or help you treat constipation with medicines or laxatives.
The list of certain medicines that can cause constipation include:
Paracetamol - if more than seven tablets are taken in a week
Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen
Iron and calcium supplements
Anticholinergic agents or medicines that oppose the actions of the neurotransmitter acetylcholine. These include drugs for Parkinson’s disease, depression, delusions, hallucinations, and muscular spasms.
Anticonvulsants (drugs used to treat seizures) such as carbamazepine, phenobarbital, and phenytoin.
Cancer drugs such as vinblastine, vincristine, vindesine, and vinorelbine
Calcium-channel blockers such as verapamil
Water pills (diuretics) such as furosemide
4. Underlying medical conditions
Constipation can be caused by various health conditions like the following:
Irritable bowel syndrome
Endocrine disorders like Diabetes, Hypothyroidism, Hyperparathyroidism, Hypercalcemia, Hypokalemia, insufficient production of pituitary hormones
Tumor of the adrenal gland
Delayed emptying of the colon caused by pelvic floor disorders and colon surgery
Narrowing of colon or bowel stricture
Other abdominal cancer that presses on the colon
Lazy bowel syndrome in which there is slow movement of waste through the digestive tract
Neurogenic disorders like spinal cord injury, stroke, multiple sclerosis, Parkinson’s disease, brain injury etc.
Structural defects in the digestive tract like fistula, imperforate anus, malrotation etc.
Diseases like amyloidosis, lupus erythematosus, and scleroderma
5. Overuse of laxatives
Laxatives are common medicines used to treat constipation. In most cases, people with this condition do not consult a doctor but use laxatives to get rid of constipation. However, it is reported that overuse of laxatives is not good for your health. People who use laxatives frequently tend to lose the ability to pass stools without such aids. Hence, in the long run, it can lead to more use of laxatives and an increased risk of constipation.
The use of conventional laxatives, as a first step for the treatment of constipation, are not effective in many cases. Moreover, laxatives can cause drug interactions with other medications.
Risk Factors For Constipation
The risk factors for constipation include:
Age - constipation is more common in older adults
Gender - constipation occurs more frequently in women
Resisting or delaying the urge to pass stools
Travel or other changes in daily routine
Less physical activity - people with more sedentary lifestyle are more likely to have constipation
Depression or any eating disorder
Pregnancy especially during the last months
Constipation is a common symptom during pregnancy, but this doesn’t mean that every pregnant woman will suffer from constipation. So, if you are pregnant and suffering from constipation, here’s a quick guide with tips to help control the condition.
Diagnosis Of Constipation
The diagnosis of constipation depends largely on the patient’s history. The doctor will take:
Medical history (other health problems and medications taken)
Dietary history (intake of fiber and water)
Symptoms history (duration and severity)
This may include
1. Abdominal examination in which the abdomen may be examined for distension. The enlarged or swollen bowel may point towards constipation.
2. Rectal examination may be done to look for scars, hemorrhoids, fistulas or fissures around the perineum, the area between anus and scrotum (in males) or vulva (in females).
These tests may be done to look for underlying conditions that cause constipation. These may include:
2. Stool Examination to check for any signs of infection, inflammation, and cancer.
3. Radiology tests such as Abdominal X-ray, CT scan or MRI of the colon to assess the length and width of the colon or any lesion that may cause obstruction.
4. Barium enema study is an imaging study that uses x-rays along with an enema (containing barium) to detect abnormalities inside the colon. The contrast solution containing barium is injected into the rectum. Barium enema produces better images as compared to other imaging studies.
5. Defecography is a modification of the barium enema examination. A thick paste of barium is inserted into the rectum of a patient through the anus. This procedure then examines the process of defecation and gives information about anatomical abnormalities of the rectum and pelvic floor muscles during defecation.
6. Magnetic resonance imaging defecography is one of the latest tests for evaluating defecation. It is similar to barium defecography, however, MRI is used instead of X-rays to provide images of the rectum during defecation.
7. Colonic transit (marker) studies involve consuming a small amount of a radioactive substance usually in the form of a pill, and then tracking the amount of time and how the substance moves through the colon.
8. Colonoscopy or endoscopy of the colon is a diagnostic method in which a long, flexible, lighted tube is inserted through the rectum to get an internal view of the colon. During this procedure, biopsy may also be taken to test for cancer or any other problem.
Prevention Of Constipation
1. Eat a high fiber diet comprising fruits, vegetables, legumes and whole grains. Restrict foods with low amounts of fiber such as processed and packaged foods, milk and meat products.
2. Drink a minimum of 8 glasses of water during a day. Restrict intake of alcohol and caffeine in the form of coffee and soft drinks as they tend to dehydrate the body.
4. Stay active and exercise regularly
5. Do not delay the urge to pass stools
6. Try to manage stress
Specialist To Visit
In most cases, constipation improves on its own with simple changes in diet. However, consult a doctor if you have
1. Had less than three bowel movements in a week
2. Pain while passing stools
3. Rectal bleeding
Doctors/specialists who can help in the diagnosis and treatment of constipation are:
Pediatrician(in case of children)
Treatment Of Constipation
Treatment for constipation mainly includes lifestyle changes and medications to soften the stools or stimulate its movement through the colon. Mild constipation gets better with lifestyle modifications. However, severe constipation may require medications.
1. Lifestyle modifications
Constipation can be easily avoided by making a few changes to our daily habits including diet and lifestyle. These include:
First and foremost, drinking at least 3 litres of water is a must for adults. Water hydrates the body and softens stool and aids its movement from the colon.
Include fibre-rich vegetables like carrots, cabbage, cauliflower, broccoli, spinach, varieties of gourd etc. in your diet. Blanch the veggies and sprinkle on some seasoning and spices. Have portions equivalent to 250-300 grams daily.
A fruit a day will keep constipation blues away. Besides containing dietary fibre, fruits like orange, apple, papaya, dates, figs etc. are packed with nutrients.
Substitute white rice and polished wheat with whole grain products like brown rice and unpolished wheat. Oats also have similar qualities. Eat a cup full of these healthy grains daily to fight constipation.
Using the toilet at a fixed time every day will trick the body’s biological clock into creating a routine to defecate effectively. The morning is the best time to get started in this regard.
Avoid alcoholic drinks as much as possible. Alcohol dehydrates the body and causes stool to harden.
Start exercises like jogging, cycling, running and swimming to boost your metabolic rate and fight constipation.
Lessen or eliminate the consumption of oil and sugar-rich food from your diet as these upset digestion, cause constipation and lead to obesity.
Laxatives are compounds which promote bowel movements and are used to relieve and prevent constipation. Some of these medicines are available over the counter (OTC) and come in the form of capsules, suppositories, enemas, pills, gums, and liquids. Most laxatives are advised to be used only for a short period of time. Use medicines only if recommended by your doctor.
Bulking agents such as bran and psyllium are fiber supplements, which are usually recommended for normal constipation.They contain fiber which add bulk to the stools and helps the stools to quickly move through the colon. People on bulking agents should drink ample amounts of water to maintain hydration.
Lubricants help in smooth movement of stools through the colon.eg. mineral oil.
Stool softeners work by moistening the stools eg. docusate sodium
Enemas use a thin tube to inject a liquid or a gas into the rectum to expel its contents. Examples: Phosphate enema, mineral oil retention enema, and soapsuds enema.
Suppositories such as those containing glycerin or bisacodyl are placed into the rectum.
Chloride channel activators such as Lubiprostone are used to treat chronic constipation.
Complications Of Constipation
Constipation if left untreated or if suffering from a long time may cause:
1. Hemorrhoids, a condition that leads to swollen veins in the rectum and anus.
2. Rectal prolapse in which a part or the entire wall of rectum stretches and protrudes out from the anus
3. Anal fissures which are small tears in the anus that cause pain and bleeding.
4. Fecal impaction is a condition in which hardened stools get stuck in the intestines due to long term constipation.
Alternative Therapies Of Constipation
It is used to treat chronic constipation. It involves training of pelvic floor muscles for passing stools by electronic monitoring.
Many natural products that may help in constipation are:
Foods To Relieve Constipation
Fruits, cereals, leafy vegetables, curd, and seeds can help you to deal with constipation. These foods are known to add bulk to stools, increase bowel frequency, soften the stools and decrease the gut transit time (which is the time taken by food to move through the digestive tract). However, keep a check on your fiber intake as excess fiber can also worsen constipation.
Here are some of the common foods to relieve constipation at home.
Green kiwi fruit increases the frequency of stools, softens the stools and eases defecation. This could be attributed to the presence of fiber (2-3 gm of dietary fiber per 120 gm of the fruit), which plays a key role in bulking of the stools and relieving constipation. It also contains an enzyme which stimulates the motility of the upper gastrointestinal tract.
Tip: You can peel the fruit, cut it into thin slices and either eat it raw or add to salads or smoothies to fight constipation.
A medium-size banana (which weighs around 100 g) contains about 3 g of fiber. It not only absorbs water to soften the stools but also improves the movement of stool through the intestinal tract.
Tip: Eat a banana every day for regular bowel movements and prevent chronic constipation. Bananas are best eaten as a whole and not in smoothies or milkshakes.
Dried plums, also known as prunes, contain around 6.1 g of fiber per 100 g of fruit, which is very high as compared to other commonly available fruits. Moreover, it is rich in fructose and contains a high amount of sorbitol (14.7 g per 100 g), a sugar compound that has laxative properties.
Tip: Eat prunes as a whole. Avoid drinking prune juice to deal with constipation because it has less sorbitol and fiber content.
4. Apple (Seb)
A medium sized apple contains around 4.4 gm of fiber, most of which is pectin. This fibre is broken down into short-chain fatty acids by the intestinal bacteria. These fatty acids absorb water, soften the stool and decrease the intestinal transit time, relieving constipation.
Tip: Eat the apple with its peel to increase your fiber intake. You can add apples to a fruit salad.
You can get around 22% of your daily recommended allowance of dietary fiber if you eat a medium-sized pear. In addition to fiber, pears are also rich in fructose and sorbitol.
Tip: Pears work best when eaten as a whole. However, drinking pear juice is usually recommended in kids whose intestinal function is not fully matured.
Raw, as well as dried figs, are a great source of fiber, which not only relieves constipation but also promotes a healthy bowel. Around 75 g of dried figs and raw figs contain 7.3 g and 2 g of fiber respectively.
Tip: You can snack on figs by including them in your fruit salads, juices or smoothies. However, eating it in its whole form is regarded as the best way to up the intake of fiber.
Spinach is one of the common leafy vegetables that is loaded with fiber. Moreover, it is also rich in various minerals and vitamins that improve digestion. A cup of spinach contains around 4 g of fiber, which is known to add bulk to stools and makes it easier to move through the gut.
Tip: You can make palak parathas and palak paneer or add palak to smoothies or salads.
Oats are good for people suffering from constipation as it is rich in fiber. Oat bran is the outer covering of the grain, which is loaded with fiber. Moreover, adding around 8 g of oat bran to your diet every day reduces the use of laxatives.
Tip: Oat bran can be added to wheat flour, granola mixes or bakery items. But use oat bran and not ready-to-eat oats, as the latter contains less fiber as compared to oat bran.
One of the commonly used traditional remedies to deal with constipation, flaxseeds act as a natural laxative. This is due to the presence of soluble as well as insoluble fiber. A tablespoon of roasted flax seeds contains around 3 g of fiber.
Tip: You can add flaxseeds to cereals or use it in salads. Flaxseed powder can be added to wheat flour or milk.
Unlike potatoes, sweet potatoes are rich in fiber. A medium-sized sweet potato contains around 3.8 g of both insoluble fibers such as cellulose and lignin and soluble fiber such as pectin. Both types of fiber play a key role in easing constipation by improving the bowel movement and adding weight to stools.
Tip: You can eat sweet potatoes in the boiled or roasted form to increase your intake of fiber. Alternatively, you can steam it, mash it and add it to curries or salads.
Probiotics contain bacteria such as bifidobacteria and lactobacilli which help maintain the level of good bacteria in the digestive tract which aids proper digestion.
Tip: Curd and buttermilk are the best natural forms of probiotics that are easily available. You can add curd to your diet.
