Dry cough and loss of appetite

Influenza and COVID-19 can reduce appetite while causing cough, fever, tiredness, or body aches. Gastroenteritis may add nausea, vomiting, or diarrhoea. Gastritis and peptic ulcer disease can make eating uncomfortable, often with upper-abdominal pain or burning. Hepatitis A can cause appetite loss with nausea, dark urine, pale stools, or yellowing of the skin or eyes. Depression may affect appetite and energy, while persistent unexplained symptoms need assessment. Pancreatic cancer is one less common cause of appetite loss and digestive change; this combination does not identify it by itself.

Take frequent small sips of water or an oral rehydration drink if intake is low. Choose small, nourishing meals and bland foods if nausea or stomach discomfort is present. Avoid smoke and other cough triggers. Record fever, bowel changes, abdominal pain, urine colour, and how much you are drinking. Consider testing or medical advice for a respiratory infection when exposure or compatible symptoms are present. Do not stop prescribed medicines without asking the prescriber, and avoid alcohol if liver illness is possible.

Seek urgent help for trouble breathing, chest pain, coughing blood, confusion, fainting, severe dehydration, black stools, vomiting blood, severe abdominal pain, or yellow skin with marked illness. Arrange prompt assessment for inability to eat or drink, ongoing vomiting, worsening cough, persistent fever, unexplained weight loss, or appetite loss that does not improve. Children, older adults, pregnant people, and those with chronic disease may become dehydrated sooner.

Could a respiratory, stomach, liver, or emotional health problem explain both symptoms? Do I need an examination or testing? How can I maintain fluids and nutrition safely?
