What Causes Loss of Appetite

Stress and Anxiety

Stress and anxiety are common emotional factors that can mess with your appetite. When you’re stressed, your body releases hormones like cortisol, which can make you lose interest in food. If you notice you’re not hungry during stressful times, this could be why.


Depression can also cause you to lose your appetite. Unlike stress, however, depression often lingers, affecting your desire to eat for extended periods. So, if you’ve been feeling down for a while and also aren’t eating much, depression might be the culprit.

Antidepressants and Antianxiety Medication

Certain medications, such as antidepressants and antianxiety meds, can make you lose your appetite. It’s a common side effect, so if you’ve recently started a new medication and find you’re not as hungry, check with your healthcare provider.


People undergoing chemotherapy often experience loss of appetite. The treatment can affect your taste buds and cause nausea, which obviously makes eating less appealing.

Liver Disease

Liver disease can affect your appetite in a significant way. Your liver plays a crucial role in digestion, and when it’s not working properly, you might not feel like eating. According to medical studies, loss of appetite is a common symptom in liver disease patients.

Kidney Failure

Kidney failure is another serious condition that can cause loss of appetite. The kidneys help to filter waste from your body, and when they’re not functioning well, toxins can build up in your bloodstream, leading to a lack of interest in food.

Heart Problems

You might be surprised to learn that certain heart problems can also affect your appetite. Conditions like heart failure can make eating physically uncomfortable, so you may eat less as a result.

Hormonal Imbalance

Hormonal imbalances could affect your appetite. Hormones like leptin and ghrelin regulate hunger, and when these are out of balance, you might not feel like eating.

If you’re experiencing a prolonged loss of appetite, it’s essential to consult a healthcare provider for proper diagnosis and treatment.
