It is common to experience changes in the way things smell during illness, including the flu. These changes can be attributed to a temporary decrease in your sense of smell or alterations in the way your brain processes smells due to congestion or inflammation in the nasal passages. It is important to stay hydrated, rest, and take care of yourself while you are sick. If your sense of smell does not return to normal after your flu symptoms subside, it is advisable to consult a healthcare provider.
