Going to the bathroom is something we all do every day. But sometimes, things don’t go as smoothly as they should, and we end up with constipation. This is when your digestive system gets a bit backed up, and it can take a while for food to leave your body. For some people, constipation happens a lot, making it tough to pass stools without straining.
Constipation starts in the colon, which is also called the large intestine. The colon is a muscular tube divided into four parts: the ascending, transverse, descending, and sigmoid colon. These connect to the rectum and anus. The small intestine sends a mixture of food, bile, and digestive juices to the large intestine. As this mixture moves through the colon, water is absorbed, turning it from liquid into solid stool. The longer this takes, the more water is absorbed, making the stool harder.
When the stool reaches the sigmoid colon, it goes through one last absorption before entering the rectum. This stretches the rectum walls and signals the internal anal sphincter to relax. At this point, you can decide whether to go to the bathroom or hold it in. This decision is controlled by the pelvic floor muscles, especially the puborectalis and the external anal sphincter. The puborectalis forms a sling around the rectum, creating an angle called the anorectal angle. When you relax your external anal sphincter, the stool is expelled.
When you’re constipated, just feeling the urge to go might not be enough. There are usually two main reasons for constipation: slow movement of stool through the colon and pelvic floor dysfunction. In the first case, the stool moves too slowly, causing too much water to be absorbed, which makes it dry and hard. In pelvic floor dysfunction, the stool is hard to pass because the pelvic floor muscles are too tight or because of pelvic organ prolapse, which can happen after childbirth or as we age. Both of these issues can make the anorectal angle sharper, making it harder to pass waste.
To help identify constipation, researchers have created tools like the Bristol Stool Chart. Most people can figure out if they’re constipated by looking at this chart. When using the toilet, it’s best to be in a squatting position. Sit on the toilet seat, put your feet on a stool, and lean forward with a straight back. This helps straighten the anorectal angle and makes it easier to pass stool.
Missing a day without a bowel movement isn’t usually a big deal. But if constipation becomes a regular problem, you can try some simple changes. Eating more fiber-rich foods like vegetables, exercising regularly, doing abdominal massages, and drinking 6 to 8 cups of water daily can help you get back to regular bathroom visits.
Use clay or playdough to create a model of the digestive system, focusing on the colon and its four parts. Label each part and explain how constipation can occur when the stool moves too slowly through the colon. This hands-on activity will help you visualize the process and understand the role of each part in digestion.
Keep a food diary for a week, noting down everything you eat and drink. At the end of the week, analyze your diet to see how much fiber you are consuming. Discuss with your classmates how dietary changes could help prevent constipation and share tips for incorporating more fiber-rich foods into your meals.
In groups, create a short skit that demonstrates the journey of food through the digestive system, highlighting where and how constipation can occur. Use props and costumes to make it fun and engaging. This activity will help reinforce your understanding of the digestive process and the causes of constipation.
Create a poster that educates others about constipation, its causes, and ways to prevent it. Include information on the importance of diet, exercise, and proper bathroom posture. Display your poster in the classroom or school hallway to raise awareness among your peers.
At home, try using a small stool to elevate your feet while sitting on the toilet. Note any differences in comfort or ease of bowel movements. Share your experiences with the class and discuss how posture can impact the anorectal angle and help alleviate constipation.

Visiting the bathroom is a normal part of daily life. However, sometimes constipation can occur, which is a condition that leads to a backup in the digestive system. The food you consume can take several days to exit your body, and for many, constipation can become a chronic issue, characterized by the regular passage of hard stools and straining.
So, what causes this condition? Constipation originates in the colon, also known as the large intestine. This muscular organ is divided into four sections: the ascending, transverse, descending, and sigmoid colon, which connects to the rectum and anus. The small intestine delivers stool, made up of ingested food, bile, and digestive juices, to the large intestine. As the stool moves through the colon, the organ absorbs most of the water it contains, transforming it from liquid to solid. The longer this process takes, the more water is reabsorbed, resulting in firmer stool.
Once the stool reaches the sigmoid colon, a final absorption occurs before it enters the rectum, stretching its walls and signaling the internal anal sphincter to relax. At this point, you can usually decide whether to expel or retain the stool, a process regulated by the pelvic floor muscles, particularly the puborectalis and external anal sphincter. The puborectalis forms a sling-like structure around the rectum, known as the anorectal angle. When you voluntarily relax your external anal sphincter, the stool is expelled.
When experiencing constipation, the urge to visit the bathroom may not be enough to prompt action. Typically, there are two main factors involved: the slow movement of stool through the colon and/or pelvic floor dysfunction. In the first case, stool moves too slowly through the intestines, leading to excessive absorption of liquid, which makes the stool dry and hard. In pelvic floor dysfunction, stool becomes difficult to eliminate due to tightened pelvic floor muscles or pelvic organ prolapse, often resulting from childbirth or aging. Both issues can make the anorectal angle more acute, complicating waste expulsion.
To accurately identify constipation, researchers have developed tools like the Bristol Stool Chart. Most people can recognize their experiences with constipation by referring to this chart. Ideally, when using the toilet, one should be in a squatting position. With your buttocks on the toilet seat, elevating your feet on a stool and leaning forward with a straight back can help straighten the anorectal angle and facilitate waste passage.
Going a day without a bowel movement isn’t usually a cause for concern. However, if you are experiencing chronic constipation, simple dietary and lifestyle changes—such as increasing fiber intake with vegetables, engaging in regular exercise, performing abdominal massages, and drinking 6 to 8 cups of water per day—may help restore regular bathroom visits.

Constipation – A condition in which there is difficulty in emptying the bowels, often associated with hardened feces. – Eating more fiber can help prevent constipation by making it easier for the body to pass stool.
Colon – The longest part of the large intestine, which removes water from digested food and stores waste until it is ready to leave the body. – The colon plays a crucial role in absorbing water and salts from the food we eat.
Intestine – A long, tube-like organ in the digestive system that helps break down food and absorb nutrients. – The small intestine is where most of the digestion and absorption of nutrients occurs.
Stool – The solid waste matter that is discharged from the intestines through the anus; feces. – Doctors often ask for a stool sample to check for signs of infection or disease.
Pelvic – Relating to the pelvis, the lower part of the torso between the abdomen and the legs. – Pelvic exercises can help strengthen the muscles that support the bladder and bowel.
Muscles – Bundles of fibrous tissue in the body that have the ability to contract, producing movement or maintaining the position of parts of the body. – Regular exercise helps to build strong muscles, which are important for overall health.
Water – A clear, colorless, odorless, and tasteless liquid that is essential for most plant and animal life and is the most widely used solvent. – Drinking plenty of water is important for maintaining good health and aiding digestion.
Fiber – A type of carbohydrate that the body cannot digest, which helps regulate the body’s use of sugars and keeps hunger and blood sugar in check. – Foods high in fiber, like fruits and vegetables, help keep the digestive system healthy.
Digestion – The process by which the body breaks down food into small components that can be absorbed into the bloodstream. – Digestion begins in the mouth, where enzymes in saliva start to break down food.
Anus – The opening at the end of the digestive tract through which stool leaves the body. – The anus is the final part of the digestive system, where waste is expelled from the body.
