How should common GLP-1 gastrointestinal side effects be managed?
At Alloy, we always want you to feel supported, not sick. Mild gastrointestinal side effects are common with GLP-1 medications, but they should be manageable and improve as your body adjusts.
Here’s how we recommend managing them:
1. Start low and titrate slowly
Side effects are often strongest after the first dose at a new level. Many patients find that symptoms improve over the next few weeks at the same dose. That is why, here at Alloy, your doctor tailors dosing month by month instead of automatically increasing it. If you are losing weight steadily or feeling unwell, we may hold or even lower your dose.
If symptoms are disruptive, message your Alloy doctor. In some cases, we can adjust your dose or prescribe anti nausea medication.
2. Eat smaller, protein focused meals
GLP-1s slow stomach emptying, so large meals can worsen nausea or discomfort.
Try smaller, more frequent meals
Aim for 75 to 100 grams of protein daily
Avoid high fat, greasy, spicy, or sugary foods
Skip carbonated drinks if they worsen bloating
3. Prioritize fiber and hydration
Constipation is common because digestion slows and appetite decreases.
Drink at least 64 oz of water daily
Make sure you are getting enough fiber from whole foods
Consider a fiber supplement if needed
4. Be mindful of food choices early on
When starting a GLP-1, avoid experimenting with rich or unfamiliar foods. Your stomach is emptying more slowly than it ever has before, so heavy meals can trigger nausea.
5. Know what is not normal
Mild nausea, constipation, loose stools, or reflux can happen. However:
Vomiting is not how these medications cause weight loss
Persistent or severe vomiting is a red flag
Feeling so unwell that you cannot function is not expected
If that happens, contact your doctor right away.
