When should you worry about difficulty swallowing if you have stomach cancer?

Difficulty swallowing, also called dysphagia, may feel like food sticking, moving slowly, or causing discomfort behind the breastbone or in the upper abdomen. Most people with stomach cancer notice difficulty swallowing when disease or treatment affects the passage between the throat, oesophagus, and stomach. Swelling, narrowing, reflux-related irritation, infection, or a treatment side effect can also contribute. The sensation may occur with solid foods, liquids, or both, so describe the pattern rather than trying to identify the cause yourself.

Your clinician may ask whether the problem began suddenly, whether it is getting worse, and whether you are coughing or choking during meals. These details help determine how quickly you need assessment and whether swallowing, nutrition, or hydration support is needed.

Contact your oncology or gastroenterology team soon about any new swallowing problem, even if you can still eat and drink. Keep a brief record of foods and drinks that cause trouble, pain, coughing, or regurgitation. Until you receive advice, take small bites, eat slowly, sit upright while eating, and follow any texture or nutrition plan already provided. Do not stop cancer medicines or change treatment on your own. If swallowing makes it difficult to take prescribed medicines or fluids, tell the team the same day.

Seek emergency help now if you cannot swallow saliva or fluids, have trouble breathing, are choking, or feel that food is completely stuck. Get urgent medical assessment for repeated vomiting, signs of dehydration such as very little urine or marked dizziness, vomiting blood, or black stools. Prompt care is also needed if swallowing pain is severe, symptoms are rapidly worsening, or you are becoming too weak to eat and drink. These warning signs need assessment regardless of how common difficulty swallowing is in stomach cancer.

Ask: Could the swallowing change be related to the cancer, treatment, reflux, or another problem? Do I need an examination or a swallowing test? Which foods and drinks are safest for me right now? How can I maintain fluids, calories, and medicines if swallowing worsens? Who should I contact outside clinic hours, and which symptoms mean I should go straight to emergency care?
