Can a common cold cause loss of appetite?

A blocked nose can reduce the flavour of food, while a sore throat may make swallowing uncomfortable. Feverishness, mucus drainage, poor sleep, and feeling generally unwell can also lower interest in meals. Appetite often returns as the respiratory symptoms improve.

Loss of appetite has many possible causes. Vomiting or diarrhoea may suggest gastroenteritis; upper-abdominal pain can occur with gastritis or a peptic ulcer; persistent low mood can accompany depression. Influenza and COVID-19 can also cause reduced appetite, so the full symptom pattern matters.

Take frequent sips of water or an oral rehydration drink if you are sweating, vomiting, or eating very little. Try small portions of soft foods such as soup, yoghurt, porridge, rice, or toast, and choose foods with protein when tolerated. Do not force a large meal when nausea or throat pain is present.

Monitor urination, alertness, and ability to drink. A pharmacist can advise on symptom relief and whether a medicine is suitable with your health conditions. Avoid alcohol while you are unwell and do not give medicines intended for adults to children.

Seek medical advice if appetite remains low after the cold symptoms improve, weight is falling without trying, or eating is limited by ongoing pain. Get urgent help for confusion, fainting, severe weakness, very little urine, blood in vomit or stool, severe abdominal pain, or breathing difficulty. Babies, older adults, and people with significant medical conditions may become dehydrated sooner.

Could another illness explain my appetite change? How can I protect hydration with my symptoms? Are any of my medicines affecting appetite or taste?
