Prateek Yadav was battling illness for a long time

Reports indicate that Prateek Yadav had been suffering from a serious lung condition for a long time. He had a blood clot in his lungs, for which he was undergoing treatment. His condition suddenly worsened in the morning and he became unresponsive. His family rushed him to the hospital, but it was too late. Many people were shocked to hear the news of his passing.

How dangerous is a clot in the lungs?

According to the health information organization Mayoclinic, a blood clot in the lungs is considered extremely dangerous. Medically, it's called a pulmonary embolism. This occurs when a blood clot formed in the body's veins travels to the lungs and lodges in the arteries, blocking blood flow. In most cases, this clot travels from the deep veins of the legs to the lungs, a condition known as deep vein thrombosis.

What problem does this cause to the patient?

When the flow of blood and oxygen to the lungs is blocked, breathing becomes difficult. Patients may experience symptoms such as sudden shortness of breath, chest pain, dizziness, or fainting. Sometimes, blood may be coughed up. Doctors say this disease can be fatal because the affected lung gradually fails, preventing adequate oxygen from reaching the rest of the body.

Timely treatment can save the patient's life

According to the American Lung Association, if timely treatment is received, the patient's life can be saved. Treatment focuses on slowing the growth of blood clots and preventing the formation of new ones. People with prolonged sitting, vascular disease, obesity, smoking, and chronic heart or lung disease are considered at higher risk.
