How GLIP helps with side effects

A calm read before the first bite

  • See, before you eat, whether a meal is likely to be gentle or rough given its fat, portion, protein and fiber.
  • Get a calmer swap the moment a meal looks like a likely trigger.
  • Keep a simple, private food log to find your own patterns.

Common questions

What causes side effects on GLP-1 medications?

GLP-1 receptor agonists slow stomach emptying and act on appetite centers in the brain. That mechanism is part of why they work, and it's also behind most of the day-to-day side effects people notice. What you eat can dial the effect up or down.

Which foods tend to help with side effects?

In general, smaller meals, enough protein, steady fluids, and foods that aren't overly greasy, sugary, or heavy tend to sit better. The leaf pages below get specific.

When should I call my prescriber about side effects?

If symptoms are severe, persistent, stop you from staying hydrated, or come with pain, vomiting, or other warning signs, contact your prescriber or seek care. Don't change your medication dose on your own.
