Loss of appetite and shortness of breath

Breathlessness can arise from the lungs, airways, heart, blood, or an allergic reaction. Acute Bronchitis, Asthma, Bronchiectasis, and COPD can cause breathing difficulty, sometimes with cough or wheeze. Anaemia may reduce oxygen delivery and leave you tired or breathless. Angina or Atrial Fibrillation can affect how the heart handles exertion. Anaphylaxis can cause sudden breathing difficulty with swelling or hives. Loss of appetite may accompany the illness or the effort of breathing; the symptom combination does not identify one diagnosis.

Record whether breathing is worse at rest, with walking, or when lying down. Note chest discomfort, palpitations, fever, cough, wheeze, swelling, dizziness, and the speed of onset.

Stop strenuous activity and sit upright while arranging medical advice. Take small sips of fluid and light food if comfortable, but do not delay help to eat. Use a prescribed reliever inhaler only as directed. Avoid smoke and other known triggers. If this is new, worsening, or limiting ordinary activity, seek same-day clinical advice.

Call emergency services for severe or rapidly worsening breathlessness, blue or grey lips, inability to speak in full sentences, crushing or spreading chest pain, fainting, confusion, or sudden facial or tongue swelling. A racing or irregular heartbeat with dizziness, or breathlessness at rest, also needs urgent assessment.

Ask what may be driving the breathlessness, whether oxygen level or heart and lung checks are needed, and how to use any inhaler safely. Share your onset, triggers, activity limits, medical history, and medicines.
