Common cold and no appetite: what to know

A blocked nose reduces the ability to smell, which changes how food tastes. A sore throat, cough, mouth breathing, or tiredness can make chewing and swallowing uncomfortable. Appetite usually returns as the infection settles, but reduced intake matters more in babies, older adults, and people with medical conditions that affect hydration or blood sugar. A new earache, worsening cough, facial pain, or breathing symptoms may point to a complication such as middle ear infection, sinusitis, or acute bronchitis rather than an uncomplicated cold.

Take frequent sips of water, oral rehydration fluid, or another suitable drink. Choose small portions that are easy to swallow, such as soup, yoghurt, porridge, soft fruit, or eggs, and eat when you feel most able. Cool or warm foods may be more comfortable than very spicy or acidic choices. Clear your nose before meals if congestion affects taste or breathing. Do not force food, but keep offering drinks and monitor urination, alertness, and mouth dryness. Children need an adult to watch their drinking and wet nappies or toilet visits.

Get urgent help for difficulty breathing, choking, unusual drowsiness, confusion, or inability to swallow fluids. Arrange medical advice if vomiting prevents drinking, urine becomes very infrequent or dark, the person has a dry mouth and worsening weakness, or appetite does not begin to recover as other symptoms improve. For a child, seek advice sooner if they refuse drinks, have fewer wet nappies, or seem unusually sleepy. Ear pain, facial swelling, a harsh breathing sound, or a cough that is becoming more severe also warrants assessment.

How can I protect hydration while appetite is low? Are my medicines or health conditions affected by eating less? What signs would mean the symptoms are no longer consistent with a simple cold?
