How common is loss of appetite in sepsis?

Sepsis is a dangerous body-wide response to an infection. When someone is acutely unwell, fever or feeling unusually cold, nausea, weakness, pain, and exhaustion can reduce their desire to eat or drink. The important issue is the overall pattern of illness, not appetite alone. A person with sepsis may deteriorate quickly, while reduced appetite also commonly occurs with minor infections and many non-infectious conditions.

If a person seems significantly unwell with a suspected or known infection, seek urgent clinical advice rather than waiting to see whether appetite returns. Tell the clinician about recent infection symptoms, new medicines, chronic health conditions, fluid intake, urine output, alertness, and how quickly the person has changed. If they are awake and able to swallow safely, offer small sips of fluid while arranging help; do not force food or drink.

Call emergency services or go to an emergency department immediately for confusion, difficulty breathing, blue, grey, or mottled skin, a new rash that does not fade with pressure, collapse, severe weakness, very little urine, or a person who is hard to wake. Urgent assessment is also needed when infection symptoms are worsening rapidly.

Ask what infection is suspected, whether sepsis is a concern, what monitoring is needed, and whether the person can safely drink or eat. You can also ask what changes should prompt immediate escalation after going home and how to manage prescribed treatment.
