What is constipation and why does it Happen?

Constipation can affect someone who poos less than three times per week. Constipation can occur for a variety of reasons, including when stool moves too slowly through the colon. The more water the colon absorbs and the harder the stools become, the slower the food passes through the digestive tract. Sometimes, constipation can be caused by a blockage in the large intestine. A person in this situation will require immediate medical assistance. It could also be due to a lack of fiber or water in some cases. In the United States, one of the most common gastrointestinal complaints is constipation. Constipation causes at least 2.5 million people to visit their doctor each year.

Why does constipation happen?

Constipation occurs when your colon absorbs too much water from waste (stool), causing the stool to dry out and become difficult to push out of your body.

To back up a bit, nutrients are absorbed as food passes through the digestive tract. The partially digested food (waste) passes through the small and large intestines, the colon. The colon collects water from the waste, resulting in a solid substance known as stool. Food may travel too slowly through the digestive tract if you have constipation. This allows the colon to absorb water from the waste for an excessive amount of time. As a result, it gets dry, hard, and difficult to push out the stool.

The major symptoms of constipation are:

Lab tests: Urine and blood tests reveal hypothyroidism, anemia, and diabetes. In addition, stool samples are analyzed for infection, inflammation, and cancer.

If they do, your doctor may adjust your dose, switch you to another medication, or ask you to discontinue taking the supplement. Never stop taking your medications or supplements without first consulting your doctor.

Surgery: Constipation is rarely treated surgically. However, if a structural problem causes constipation in the colon, your doctor may recommend surgery. A blockage in the colon, a narrowing of a portion of the intestine, an anal fissure, or rectal prolapse. Certain causes of outlet dysfunction that result in constipation may be treated surgically. This is a topic that is best discussed following testing. Additionally, you may require surgery if cancer was discovered in your colon, rectum, or anus.

Bleeding from the anus, pain or redness, and inflammation in the affected area may also necessitate prompt medical attention.
