Doctors removed 28 pounds of feces from the bowels of a man who was reportedly constipated since birth.

The unnamed 22-year-old had 30 inches of his grossly enlarged bowel removed by surgeons at Tenth People's Hospital of Shanghai in China.

It is believed the young man had Hirschsprung's disease, which causes the bowels to swell because the nerves that are supposed to control the gut are missing.

Doctors said the man looked like he was nine months pregnant because of the painful enlargement and feces backup.

The medical experts believe he had been constipated for years and looked 'like he was about to explode.'

The patient said he had always suffered from constipation and used laxatives, but those only offered a brief relief.

He finally went to the hospital so doctors could relieve him of his symptoms.

Tests conducted determined the man had months, even years, worth of feces inside a portion of his colon, causing the immense swelling of his abdomen.

Dr Yin Lu said the procedure lasted three hours and removed the enlarged body part, according to Inverse Science.

HIRSCHSPRUNG'S DISEASE Hirschsprung's disease is a rare condition that causes poo to become stuck in the bowels. It mainly affects babies and young children. It means the nerves that control the movement of feces are missing from a section at the end of the bowel, which means poo can build-up and form a blockage. This can cause severe constipation, and occasionally lead to a serious bowel infection called enterocolitis if it's not identified and treated early on. Symptoms of Hirschsprung's disease are usually noticeable from soon after a baby is born, although occasionally they're not obvious until a child is a year or two old. It's not clear what causes the disease, but it's not thought to be caused by anything the mother did while she was pregnant. It sometimes run in families. All children with Hirschsprung's disease will need surgery. Advertisement

After removing his gut, surgeons stitched it up at both ends to stop feces from falling out.

Hirschsprung's disease affects one in every 5,000 babies.

The disease is uncommonly diagnosed in adults.

It also is more common for males to be affected by the condition.

Furthermore, Hirschsprung's is associated with certain inherited conditions, such as Down's syndrome and other abnormalities present at birth, such as congenital heart disease, according to the Mayo Clinic.

The condition is congenital and usually causes visually noticeable symptoms from birth, although sometimes it is not obvious until a child is a little older.

Some who develop this extreme form of constipation will need to have stoma surgery – where a small on the abdomen is created to divert the flow of feces into a pouch

Surgery is always needed in this disease

For babies, symptoms include not passing the dark poop withing 48 hours after being born.This is called meconium.

Other red flags are a swollen stomach, gassy, diarrhea and throwing up green fluids.

In young children, signs include a swollen stomach, persistent constipation, failure to thrive, not eating well and gaining lots of weight.
