Dan Blocker passed away at 43 years old in Los Angeles due to the development of a pulmonary embolism after a surgery to remove his gallbladder. He passed away at the Daniel Freeman Hospital in Inglewood at around 4 p.m.
A pulmonary embolism occurs when there is a blockage in one of the arteries in the lungs. Pulmonary embolisms typically result from clots in the blood that make their way to the lungs from the legs or other parts of the body. Surgery, such as the surgery that Dan Blocker had undergone shortly before his passing, increases an individual's risk of developing a pulmonary embolism.
