Common Symptoms & Side Effects
GLP-1 medications are safe and effective, but like any medication, they can cause side effects, especially during the first few weeks. Most are mild and go away with time. Here’s what to expect and how to manage them.
| Side Effect | How Common | What to Do |
|---|---|---|
| Nausea | Very common (30-50% of patients) |
Eat small, frequent portions. Avoid fatty or spicy foods. Nausea usually improves after 2-4 weeks. |
| Vomiting | Common (10-20%) |
Drink clear liquids in small sips. If vomiting more than 3 times per day, contact your doctor. |
| Diarrhea | Common (15-25%) | Stay hydrated. Eat bland foods (rice, banana, toast). Avoid dairy and greasy foods. |
| Constipation | Common (10-15%) | Increase fiber and water intake. Walk 10-15 minutes after eating. Consider a gentle stool softener if needed. |
| Loss of appetite | Very common (40-60%) | This is expected - the medication reduces appetite. Eat small, nutritious meals even if not hungry. Focus on protein. |
| Heartburn | Common (10-15%) | Avoid lying down right after eating. Elevate the head of your bed. Avoid coffee, alcohol, and acidic foods. |
| Bloating | Common (15-20%) | Eat slowly and chew well. Avoid carbonated drinks. Gentle movement can help. |
| Fatigue | Less common (5-10%) | Get enough rest. Eat balanced meals. If fatigue persists beyond 2 weeks, contact your doctor. |
| Headache | Less common (5-10%) | Stay hydrated. Take over-the-counter pain relievers if needed. Rest in a quiet place. |
| Fatigue | Less common (3-5%) | Stand up slowly from sitting or lying down. Drink enough water. If severe or persistent, contact your doctor. |
Serious Side Effects (Rare But Serious)
Seek immediate medical attention if you experience:
- Severe abdominal pain that doesn't go away
- Persistent vomiting preventing you from keeping down liquids
- Vision changes
- Signs of allergic reaction (difficulty breathing, swelling of face or throat, severe rash)
- Lump or swelling in the neck
- Rapid or irregular heartbeat
When Do Side Effects Improve?
The good news: most side effects are temporary and improve with time.
Weeks 1-2: Side effects are usually most intense during this period while your body adjusts
Weeks 3-4: Most people notice significant improvement
Weeks 5-8: Side effects are minimal for most patients
After 2 months: Your body has adjusted – side effects are rare
