First, after the transformation, Gregor loses his human voice, so both his family members and his manager cannot hear what Gregor said. “Have you heard Gregor speak yet?” “That was the voice of an animal,” said the director” (Kafka 14). So, losing your voice is a symptom of laryngitis that many people sometimes contract in their life. According to the article “Laryngitis Diseases and Conditions,” “Laryngitis is an inflammation of the larynx due to overuse, irritation, or infection.” Gregor works hard every day, so he could easily get sick and contract laryngitis which will cause him to lose his voice and be unable to talk to other people. Secondly, in Gregor's transformation, we can recognize that stress causes Gregor to have some negative effects on his physical health. As a result, Gregor has problems with his digestive system. After the transformation, he can no longer eat like a human, so his appetite gradually changes. According to Gregor Samsa in “The Metamorphosis” “…but the milk didn't taste good. Milk like this was normally his favorite drink, and his sister had certainly left it there for him for this reason, but he, almost against his will, moved away from the plate and crawled back to the center of the room” (Kafka) . Having digestive system problems is a common symptom among many employees who work long hours in their companies. They usually do not have a suitable schedule for eating
