Constipation is when a person has difficulty passing stool. It can also cause pain, bloating, nausea, and other symptoms. Depending on the cause, medical treatments and home remedies may help.
Constipation can happen for many reasons, such as when stool passes through the colon too slowly. The slower the food moves through the digestive tract, the more water the colon absorbs, and the harder feces becomes.
Sometimes, constipation results from a blockage in the large or small intestine. In this case, a person needs urgent medical attention. At other times, it may be due to a lack of fiber or water.
Read on to learn more about the symptoms and causes of constipation. This article also discusses laxatives and other remedies that may help relieve constipation.

Constipation in babies and infants
Constipation can sometimes affect babies and infants.
If a newborn does not pass meconium, their first solid stool, within 48 hours of birth, they may have Hirschsprung’s disease. This is a condition where certain nerve cells are missing from part of the large intestine. Stool is unable to move forward in the affected area of the colon, which causes a backup.
A healthcare professional will usually be able to spot these symptoms and recommend surgery as treatment. In most cases, the outlook is good for babies born with this condition.

Constipation in pregnancy
According to the U.K.’s National Childbirth Trust, around 40% of people experience constipation during pregnancy. It may be particularly common toward the end of pregnancy.

Constipation may resolve on its own without the need for prescription treatment. However, laxatives can improve symptoms in the short term.

Other treatment options
If constipation does not respond to laxatives, a doctor may suggest an abdominal imaging test or colonoscopy to see if an underlying condition is causing a blockage.
