Embolism is a medical condition that occurs when a substance, such as a blood clot, air bubble, or fat droplet, travels through the bloodstream and lodges in a blood vessel. This blockage can restrict blood flow to vital organs, leading to serious health issues. Common types of embolism include pulmonary embolism, which affects the lungs, and cerebral embolism, which can cause a stroke. Symptoms of embolism vary depending on the location and severity of the blockage. They may include sudden shortness of breath, chest pain, or neurological changes like confusion. Prompt diagnosis and treatment are crucial to prevent complications and ensure recovery.
