Why Your Diet Matters After a Gastric Balloon
A gastric balloon is an effective tool for weight loss because it reduces stomach capacity and helps you feel full more quickly. After placement, following the recommended diet is essential for comfort, safety, and long-term success. The first week is especially important, as your stomach adjusts to the presence of the balloon.
Stage 1: Liquids and Soft Foods (First Week)
For the first seven days, you should consume only liquid and soft foods to avoid nausea, discomfort, or vomiting. Recommended options include 1.5–2 liters of water, sugar-free tea, decaffeinated coffee, liquid soups, and low-fat or lactose-free dairy alternatives such as soy, almond, or coconut milk. You may also have protein milk, low-fat kefir, low-fat yogurt, diluted, sugar-free fruit juice, and smooth vegetable or fruit purees. Avoid vegetables that cause gas, such as cauliflower and cabbage, as well as acidic fruits like oranges or grapefruit.
Transitioning to Solid Foods
After the first week, you may slowly begin adding solid foods back into your diet. This should be done gradually and carefully. If you experience symptoms such as nausea or vomiting, return to the previous stage and allow more time for your stomach to adapt. Eating slowly and listening to your body will help make this transition smoother.
General Nutrition Guidelines
After a gastric balloon, certain eating habits are key to your progress. Avoid carbonated drinks and dried legumes, which can cause bloating. Aim for three meals a day, with snacks adjusted by your dietitian. Limit spices, keep added oils to a minimum, and choose grilling, baking, or boiling instead of frying. Drink at least 1.5–2 liters of water daily, but remember not to drink liquids with meals — wait at least 30 minutes before or after eating.
Healthy Eating Habits for Long-Term Success
Try to include protein in at least one meal each day. Opt for whole grain options such as whole wheat, rye, or whole grain bread when needed. If you crave sweets, choose fruit and consider plant-based sweeteners instead of sugar. Season salads with lemon or vinegar, avoiding oil where possible. Alcohol should be avoided entirely during this period.
Staying active is just as important as eating well. A daily 30–45 minute walk supports steady weight loss and helps you maintain a healthier lifestyle after the gastric balloon.
