Everyone should eat a healthy and balanced diet because food gives us the energy and nutrients we need to lead healthy and happy lives. However, almost everyone experiences a loss of appetite at some point in their lives.

It's not unusual for a person to not feel as hungry as they normally do, but if lack of appetite persists, it could be a signifier of a more serious condition. Loss of appetite experienced with other symptoms, such as fatigue, nausea or headache, could warrant a medical visit, as it can be caused by many conditions.1Loss of Appetite By Jonathan Gotfried, et al. ‘Loss of Appetite - Digestive Disorders.’ Merck Manuals Consumer Version, www.merckmanuals.com/home/digestive-disorders/symptoms-of-digestive-disorders/loss-of-appetite

Upper Respiratory Infections

Upper respiratory infections are a common cause of appetite loss. There are over 200 different viruses known to cause symptoms of the common cold, a condition that can lead to loss of appetite.2‘Understanding a Common Cold Virus.’ National Institutes of Health, www.nih.gov/news-events/nih-research-matters/understanding-common-cold-virus Flu can also cause digestive issues, such as nausea, vomiting and loss of appetite. Unlike the typical common cold, the flu is more likely to cause headaches and muscle aches.

Many conditions can cause appetite loss, so the symptom on its own shouldn't be reason for alarm. COVID-19 and other viral infections can also cause a lack of appetite.3Publishing, Harvard Health. ‘COVID-19 or Something Else?’ Harvard Health, www.health.harvard.edu/staying-healthy/covid-19-or-something-else
