Eating less is one of the most noticeable changes when taking a GLP-1, but your digestive system is adjusting too. Because GLP-1 medications can change gastric emptying, appetite, food intake, and bowel habits, it is worth paying closer attention to how your gut is functioning along the way.
Here are 5 things to pay attention to for better gut health on a GLP-1:
Bowel regularity: Constipation is common with GLP-1 medications. Changes in food intake, hydration, fibre, and digestive motility can all play a role.
Fibre intake: Eating less can mean getting less fibre. Gradually including vegetables, fruit, legumes, whole grains, nuts, and seeds can help support digestion and the gut microbiome, as tolerated.
Hydration: Adequate fluids are especially important if you are dealing with constipation, nausea, vomiting, or diarrhea.
Meal size and pace: Because GLP-1s can slow stomach emptying, smaller meals and eating more slowly may help reduce uncomfortable fullness, bloating, nausea, and reflux.
Persistent digestive symptoms: Ongoing vomiting, significant abdominal pain, severe constipation, or difficulty eating and drinking should not simply be dismissed as part of taking a GLP-1. Talk to your healthcare provider if symptoms are significant or persistent.
Supporting gut health while taking a GLP-1 is not about following a perfect diet. It is about paying attention to how your digestion is changing and giving your body the support it needs along the way.
