Does oesophageal cancer cause unexplained weight loss?

Weight can fall when a person eats smaller portions, avoids foods that feel hard to swallow, or loses appetite. Weight loss on its own has many possible causes, so it cannot identify the cause without an assessment.

A growth in the oesophagus can narrow its passage or make swallowing painful. Food may seem to stick in the chest or throat, and drinks may be easier to manage than solid food. These changes can reduce food and fluid intake over time.

Keep note of when the weight change started, whether it was unintentional, and any symptoms such as trouble swallowing, pain when swallowing, reflux, nausea, fatigue, or a persistent cough. This history helps a clinician decide what examination or tests may be useful.

Arrange a medical appointment if you are losing weight without trying, especially if meals are becoming difficult. Until you are seen, choose foods and drinks that you can swallow safely, take small frequent meals if that is easier, and avoid forcing down food that feels stuck.

A clinician may ask about eating, swallowing, medicines, digestive symptoms, and general health. They can assess for causes of weight loss and decide whether referral for further investigation is appropriate.

Seek urgent medical help if you cannot swallow liquids, are choking or repeatedly coughing during meals, vomit blood, pass black stools, become faint, or develop severe chest pain. These symptoms need prompt assessment regardless of the cause.

Contact a clinician soon for continuing unplanned weight loss, worsening swallowing difficulty, or food repeatedly sticking after you eat.

Ask what could be contributing to the weight loss, whether your swallowing symptoms need specialist assessment, and what foods or drinks are suitable while investigations are arranged. Tell them about any medicines, previous reflux, smoking history, or alcohol use if relevant.
