Why Chemotherapy Causes Loss of Appetite, and How to Fix It
Why chemotherapy causes loss of appetite, and how to fix it. Cancer treatment with chemotherapy, commonly known as chemo, is an essential part of fighting the disease, but the side effects of the drugs are something many patients face. One of the most common and worrying problems is loss of appetite. Loss of appetite doesn't happen on purpose — it results from changes in the body and emotions. Understanding the causes and solutions is important so that patients can still get enough nutrients to help restore the body and immune system.

- Changes in taste some people can no longer taste sweet or salty flavors properly
- Food smells too strong causing a feeling of disgust
2. Effects on the digestive system Chemo slows down bowel movement, the stomach doesn't function fully, causing patients to feel full quickly or bloated
3. Hormonal changes Medication and stress affect the hormones that control appetite, causing appetite to decrease
4. Psychological factors Stress, anxiety about the illness, depression, or panic about side effects
