Some People are born with their Organs Reversed | Situs Inversus

 What if you put your hand on left side of your chest and can’t feel your Heartbeat anymore! Don’t worry read this article to know more. Your heart and stomach are present on the left side, your liver is on the right. But what if I say some people are born with heart and stomach are on the right side, and the liver is on the left. They born with Flipped Organs due to an autosomal recessive genetic condition called Situs Inversus.

What is Situs Inversus?

Situs inversus is a genetic condition in which the organs in the chest and abdomen are positioned in a mirror image from their normal positions. This doesn’t always happen with all of the organs at once. Sometimes, it’s just the heart that is flipped to the other side. Sometimes several organs are flipped while others are not; like stomach and liver.

Situs inversus is a very rare condition. It is found in about 0.01% of the population or about 1 person in 10,000.

Causes of Situs Inversus

Situs inversus has an autosomal recessive pattern of inheritance

It is caused by an autosomal recessive genetic condition. An unaffected carrier mother and an unaffected carrier father have a 1 in 4 (25%) chance of having a child with situs inversus. Because many genetic steps would have to come together to cause situs inversus, the condition is rare. It does also happen with “mirror image” twins whose fertilized embryo splits late in its development.


Sometimes there are no symptoms because the organs can be functional in situs inversus. In other cases, there can be some associated complications. Often, the condition is discovered when the patient visits a doctor for completely different medical care.

Diagnosis can be made using common radiographic imaging techniques such as ultrasound, CT Scan and MRI.


No treatment needed, as most patients are healthy and have functional organs. For many patients, it doesn’t cause any other symptoms. If a person with situs inversus does have complications like a heart defect, a doctor will treat the symptoms. Surgery to reverse the organs’ positioning is usually not recommended.

I generally like to research about topics likes this & share it with you. This types of biological wonders excite me to find out more complexities of our body and its complex engineering.
