###Human: I have difficulty in concentrating on my work. What is the problem? ###Assistant: Hi. There are some reasons to have these symptoms. They are fatigue, and emotional stress, poor sleep, and a poor diet can also make it hard to concentrate. Specific psychological and physical conditions cause difficulty in concentrating on work like attention deficit hyperactivity disorder (ADHD). The surrounding people and places also play a role in creating difficulty in concentrating on work. Try to prioritize your tasks. Eat healthy foods. Always have a touch with nature. Take some breaks during the day. Do one thing at a time. I suggest you visit a psychiatrist in case if there is no improvement.
