Managing Nausea on GLP-1 Medications

Why Nausea Happens

GLP-1 medications slow gastric emptying — food stays in your stomach longer. This is part of how they reduce appetite, but it can also cause nausea, especially during dose escalation. The good news: it almost always improves within 2-3 weeks at each dose level.

What Actually Works

Eat smaller, more frequent meals

Your stomach capacity is effectively reduced. Three large meals will make you feel terrible. Five small meals works much better during the adjustment period.

Avoid high-fat foods

Fat slows digestion further. Combined with the medication's gastric slowing effect, a fatty meal can sit in your stomach for hours. Lean protein + vegetables is your friend.

Stay hydrated (but sip, don't gulp)

Dehydration worsens nausea. But drinking a full glass of water at once can also trigger it. Sip throughout the day instead.

Ginger

Ginger tea, ginger chews, or ginger capsules have genuine anti-nausea properties. Keep ginger chews in your bag for the first few weeks at each new dose.

Timing your injection

Some people find injecting before bed reduces daytime nausea (you sleep through the peak). Others prefer morning. Experiment to find what works for you.

Don't eat to the point of fullness

This is the #1 mistake. On GLP-1 medications, "full" hits faster and harder. Stop eating when you're 70% satisfied, not 100% full.

When to Contact Your Provider

• Nausea lasting more than 3 weeks at the same dose
• Vomiting more than once per week
• Unable to keep fluids down
• Severe abdominal pain

These may indicate a need to slow your titration or adjust your protocol.
