When your stomach feels unsettled, deciding what to eat can become the hardest part of the day. A familiar meal may suddenly feel too rich, too large or too strong-smelling. GLP-1-based medicines can slow stomach emptying. Nausea, vomiting and heartburn are recognised side effects, and digestive symptoms may be more common around dose increases. The Australian Mounjaro medicine information describes these effects. You do not need to push through symptoms that persist or worsen. This guide offers general food ideas for adults. Your prescriber should assess ongoing symptoms and advise on your medicine. ## Start with a smaller, simpler meal Try a smaller serving rather than sitting down to a large plate. Eat slowly, and leave room to pause rather than rushing to finish. Smaller meals more often may be easier to manage. NHS nausea guidance also recommends avoiding greasy food and strong cooking smells. A few options to try, depending on what appeals: · Plain toast or crackers with a little scrambled egg. · A small bowl of porridge, or plain yoghurt with banana. · Plain rice with soft tofu and steamed carrots. · Boiled potato with a small serving of a familiar, simply prepared food. These are examples, not a menu you have to follow. Dietary guidance for people taking weight-loss medicines suggests plain foods and trying cold foods when hot meals feel unappealing. If cooking smells are the problem, a cold option can save you having to cook while you feel sick. A short list of manageable foods is useful for an unsettled day. If that list stays very limited, ask your care team for help rather than trying to build your whole diet around it. ## Give reflux its own plan Nausea and reflux can overlap, but the practical details differ. Reflux may cause a burning feeling in the chest or a sour taste as stomach acid travels upwards. It can feel worse after eating or lying down. NHS guidance explains common reflux symptoms . Keep meals smaller and stay upright afterwards. If symptoms trouble you at night, aim to finish eating at least three hours before lying down or going to bed. This is a recommended reflux strategy , not a rule about weight loss. Notice your own triggers before cutting out lots of foods. Coffee, alcohol, chocolate, mint, high-fat foods and acidic or spicy foods can worsen reflux for some people. Mint is worth noticing because it appears in some nausea advice, yet may aggravate reflux. You do not need to eliminate every item on a trigger list. Reflux food guidance recommends discussing the foods that affect you. ## Make drinking manageable Try regular small sips rather than a large drink all at once. A cool drink may be easier when you feel nauseated, and avoiding a large drink with meals can help. NHS nausea guidance supports this approach. Vomiting can lead to dehydration. Dark urine, passing urine less often, a dry mouth or dizziness can be warning signs. If you have been losing fluids, ask a pharmacist or clinician whether an oral rehydration solution is appropriate. It replaces fluid and salts; it is not a substitute for assessment when you cannot keep fluids down. Healthdirect explains dehydration signs and treatment . If your healthcare team has given you a fluid limit, follow that personalised advice. ## Know when to get medical help Do not assume every new symptom is an expected medicine effect. · Do not dismiss chest pain as reflux. Call 000 for severe or worsening chest pain, pain lasting 10 minutes, or chest pain with breathlessness, nausea or a cold sweat. Healthdirect explains when to call an ambulance . · Seek urgent medical attention for severe abdominal pain that does not go away, especially if it spreads to your back, with or without vomiting. Australian medicine information warns this can indicate pancreatitis. See the Wegovy consumer medicine information . · Seek urgent assessment for sudden severe upper abdominal pain with fever or yellowing skin or eyes. These are listed gallbladder warning signs in the Mounjaro consumer medicine information . · Contact your healthcare team promptly for repeated vomiting, inability to keep fluids down, dark urine or light-headedness. These are reasons to seek help , not a cue to keep experimenting with meals. Severe dehydration needs urgent care. Call 000 in an emergency. For Australian nurse advice when you are unsure what to do, call healthdirect on 1800 022 222. Healthdirect lists both services . ## Bring useful details to your care team Write down when symptoms started, any recent prescribed dose change, what you could eat or drink, and whether symptoms followed meals or lying down. This gives you something concrete to discuss. Ask your prescriber about persistent symptoms before changing your medicine or adding treatment yourself. Alli can support the everyday planning part: exploring simpler meal ideas and preparing questions for your appointment. It provides chat-based education and planning support, not diagnosis, prescribing or a replacement for your doctor, pharmacist or dietitian. --- Source: https://youralli.io/resources/eating-with-glp1-nausea-reflux Alli provides general nutrition education and is not a substitute for individualized medical nutrition therapy from a licensed professional.
