When to worry about unexplained weight loss with oesophageal cancer

Oesophageal cancer can make swallowing uncomfortable or cause food to feel stuck. Reflux, pain, nausea, appetite changes, and treatment effects may further reduce food and fluid intake. The body may also use energy differently during illness. Weight loss may have several contributors, so it needs assessment rather than a guess based on the symptom alone.

Record whether solid foods, soft foods, or liquids are difficult, and note coughing or choking with meals, pain, reflux, vomiting, appetite, and fluid intake. Tell your team if eating takes much longer or you avoid foods because they feel unsafe.

Contact your oncology or upper gastrointestinal team promptly about weight loss, especially with new or worsening swallowing difficulty. Share your food and fluid record. Your team can review treatment, medicines, hydration, swallowing safety, and nutrition, and may involve a dietitian or swallowing specialist.

Use the texture and foods advised by your clinicians, and take small sips if swallowing is safe. Do not force food past a sticking sensation or start supplements without advice, because the right approach depends on your swallowing and treatment plan.

Seek urgent help if food becomes completely stuck, you cannot swallow liquids or saliva, you have severe chest pain, repeated vomiting, choking, breathing difficulty, confusion, or fainting. Contact your cancer team promptly for worsening swallowing, very little urine, or inability to maintain fluids.

Ask which food textures are safest, whether swallowing assessment is needed, how to maintain hydration, whether treatment or medicines are contributing, and which symptoms require emergency help.
