Welcome to ATD. Thank you for the query.
A loss of appetite can be quite concerning when it fails to go away. It can be a sign of a serious underlying condition, such as depression or cancer. It also commonly occurs during a sudden illness, such as an infection. When a loss of appetite continues for a long time, a person is at risk for malnutrition.
There are many causes of a loss of appetite that continues for more than a few days, including:
Infections, such as pneumonia, hepatitis, HIV, influenza, or a kidney infection called pyelonephritis
serious liver, kidney or heart disease.
For instance, chronic renal failure, cirrhosis, or congestive heart failure can cause a loss of appetite.
inflammation in the bowels or gut, such as occurs with pancreatitis, an inflammation in the pancreas, irritable bowel syndrome, or appendicitis
endocrine problems, such as diabetes mellitus, or a condition that causes low thyroid hormone levels called hypothyroidism
autoimmune disorders, conditions in which a person's immune system attacks his or her own body. Examples include rheumatoid arthritis and scleroderma.
psychiatric conditions, such as depression, schizophrenia, or an eating disorder called anorexia nervosa
medications or drugs, such as alcohol, narcotics, antibiotics.
Kindly visit a physician and get yourself evaluated completely to rule out the cause of anorexia in your case.
Hope this helps. Take care.
