The body needs food for energy and nutrients to support overall health. However, there are times when a person may experience a loss of appetite, making it difficult to consume enough food to meet their nutritional needs. Although appetite fluctuations are normal in the short term, a sustained lack or diminished appetite could suggest an underlying physical or mental health issue.
Being aware of the causes, symptoms and treatment for loss of appetite will enable the affected individual to seek early medical treatment for the same and thereby avoid any potential complications.
What is Loss of Appetite?
Loss of appetite is a decrease in the desire to eat. It can be short-term caused by stress, illness or lifestyle changes, or long-term due to chronic medical conditions.
A temporary decreased appetite may not be a cause for concern. However, reduced food consumption for days to weeks may result in weight loss, malnutrition, fatigue, and impaired immunity.
Common Reasons for Loss of Appetite
There are many different causes for the loss of appetite, some are related to minor health problems, while others are indicative of more severe illnesses.
Infections and Illness
Illness is one of the most common causes of loss of appetite. Some viral infections, bacterial infections, flu, fevers, and respiratory diseases can temporarily suppress hunger signals.
Because the body focuses on fighting the infection rather than digesting food, many people have a loss of appetite when they’re ill.
Digestive Disorders
A number of digestive conditions can affect normal eating. Common digestive problems and appetite loss are often linked.
Examples include:
Digestive uneasiness or pain can make eating unpleasant and may also lead to a long-term loss of appetite.

Psychological and emotional health have a strong impact on eating patterns and eating behaviour. Stress and loss of appetite frequently occur together.
During times of stress or anxiety-driven activity or emotions were related to hunger suppressant hormones.
