Embolism: Symptoms, Causes, Diagnosis & Treatments

In our body, blood can clot for various reasons and many times it happens naturally to prevent loss of blood due to injury. In other cases, it can clot inside the veins or arteries and start to move around the body.

This condition is typically known as Embolism and the type of embolism is classified based on where the blockage is positioned in the body. It can cause various symptoms like chest pain and shortness of breath. In normal cases, the blockage will get cleared on its own as the body can naturally break down the clots over a period of time. However, when it does not happen and the clots are located near the lungs region, it can become life threatening and you should get timely treatment at this stage to avoid complications.
