Keep an effective GLP-1 symptom diary to track side effects from semaglutide or tirzepatide. Learn what to record, when to call your doctor, and how to share data with providers.

Data-Driven Treatment
A symptom diary transforms vague complaints into actionable data. When you tell your provider "I have nausea on injection day that peaks at 6 hours and resolves by morning," they can adjust your treatment far more effectively than with "I feel sick sometimes."
What to Record in Your Symptom Diary
Whether you're taking semaglutide or tirzepatide, systematic symptom tracking helps optimize your treatment plan.
GI Symptoms
- Nausea (severity, timing, triggers)
- Vomiting (frequency, relation to meals)
- Constipation or diarrhea
- Bloating, gas, acid reflux
General Symptoms
- Headaches (location, intensity)
- Fatigue or dizziness
- Injection site reactions
- Mood changes, sleep disruption
Symptom Pattern Recognition
Injection-Day Pattern
If symptoms peak on injection day and fade within 48 hours, this is the most common pattern. Consider injecting before bed or adjusting injection timing.
Food-Triggered Pattern
If symptoms worsen after fatty or large meals, portion control and dietary adjustments may help more than medication changes.
Constant/Worsening Pattern
If symptoms persist throughout the week or worsen over time, contact your provider. You may need dose adjustment or additional evaluation.
When Your Diary Signals Action
Seek Immediate Medical Attention If You Record:
- Severe abdominal pain radiating to the back (possible pancreatitis)
- Persistent vomiting for more than 24 hours
- Signs of allergic reaction (swelling, difficulty breathing, rash)
- Neck swelling or lump, difficulty swallowing
- Signs of severe dehydration (dark urine, rapid heart rate, confusion)

Frequently Asked Questions
What side effects should I track in my GLP-1 diary?
Track nausea, vomiting, diarrhea, constipation, headaches, fatigue, injection site reactions, dizziness, bloating, acid reflux, and any other symptoms you experience. Rate severity on a 1-10 scale and note timing relative to your injection.
How detailed should my symptom diary be?
Include the date, time, symptom type, severity (1-10), duration, potential triggers (foods, activities), and what helped. Even brief notes are valuable. The goal is identifying patterns, not writing essays.
When should side effects in my diary concern me?
Contact your provider if you experience severe vomiting lasting more than 24 hours, signs of pancreatitis (severe abdominal pain radiating to the back), allergic reactions, or any symptoms that significantly impact your daily functioning.
Do GLP-1 side effects get better over time?
Yes, most GLP-1 side effects (especially nausea) improve within 4-8 weeks as your body adjusts. Your symptom diary will help you see this trend. Side effects often temporarily increase with dose escalations but improve again.
