Also known as: Anorexia
Loss of appetite is a decreased desire to eat, which may lead to unintentional weight loss. It can be caused by illness, medications, emotional factors, or underlying conditions.
Appetite regulation involves complex interactions between the brain, hormones, and digestive system. Temporary appetite loss during acute illness is a normal immune response.
Persistent appetite loss — lasting more than a few weeks — warrants evaluation as it can indicate depression, gastrointestinal disorders, chronic infections, or malignancy.
Medications are a frequently overlooked cause, with antibiotics, chemotherapy, stimulants, and many others suppressing appetite as a side effect.
There are several possible reasons you may be experiencing Appetite Loss. Here are the most common ones.
Acute illness naturally suppresses appetite as the body diverts energy to the immune response.
The stress response redirects blood away from the digestive system, reducing hunger signals.
Antibiotics, ADHD medications, chemotherapy, and opioids commonly reduce appetite.
Loss of interest in eating is a core symptom of depression, sometimes leading to significant weight loss.
