Fatigue and Loss of Appetite: Common Symptoms With Many Causes
Fatigue and loss of appetite can be caused by a wide range of conditions, from chronic pain to infections and psychological disorders. These symptoms can occur together and may indicate an underlying health issue, especially in older adults.
Chronic pain conditions like fibromyalgia, migraines, and POTS can lead to fatigue and loss of appetite. Similarly, diseases such as colorectal cancer, diabetes, and thyroid dysfunction, as well as psychological conditions like depression and eating disorders, can cause these symptoms. In children, conditions ranging from depression to cancer and anemia can be the culprit. Infections like the flu and certain medications can also lead to fatigue and loss of appetite. Other health conditions that can accompany these symptoms include anemia, Addison's disease, cirrhosis, and HIV/AIDS, among others.
Fatigue is characterized by persistent tiredness, reduced energy, and decreased motivation. Loss of appetite involves a decreased desire to eat, unintentional weight loss, and potential nausea when eating. In older adults, common causes include heart disease, hypothyroidism, rheumatoid arthritis, and sleep disorders. Psychological disorders such as stress, grief, anxiety, and eating disorders can also affect appetite and energy levels.
If fatigue and loss of appetite are accompanied by concerning symptoms like confusion, dizziness, or sudden weight loss, immediate medical help is needed. It's crucial to consult a healthcare provider to determine the underlying cause and appropriate treatment. Maintaining a balanced diet and staying hydrated can help manage these symptoms, but it's important to address the root cause to prevent further complications.
