What should you know about hair loss and loss of appetite?

A recent infection, digestive problem, low mood, or major stress can reduce appetite and disrupt the hair-growth cycle. Eating less may also reduce protein, iron, and other nutrients needed for healthy hair. Hair shedding can begin after the original illness has improved, which makes timing useful. Conditions such as Gastritis, Gastroenteritis, Depression, Influenza, and Hepatitis A can involve appetite changes, but these symptoms alone do not identify a cause. The pattern of hair loss, weight change, pain, fever, bowel symptoms, and medicines helps guide an examination.

Arrange a medical review if appetite remains low, meals are becoming difficult, or shedding is clearly increasing. Until then, choose small frequent meals with protein and energy, drink regularly, and keep a simple record of intake, weight trend, illness, stress, and hair changes. Avoid crash diets and high-dose supplements unless advised. A clinician may examine the scalp, review medicines, and request targeted tests based on your history. Do not stop prescribed medicine without discussing it.

Seek urgent care for inability to keep fluids down, signs of dehydration, vomiting blood, black stools, severe abdominal pain, yellowing of the skin or eyes, confusion, or marked weakness. Prompt review is also sensible for unexplained ongoing weight loss, a scalp rash with pain or scarring, or appetite loss accompanied by persistent low mood. Pancreatic Cancer is uncommon but serious; persistent symptoms with jaundice or abdominal symptoms should not be ignored.

Could a recent illness, medicine, nutritional gap, or mood change explain both symptoms? What examination or tests fit my pattern? How can I maintain nutrition while my appetite is low?
