What to Expect Your First Month on GLP-1 Medication

By Fifty 410 Medical Team|January 5, 2024|8 min read

> Quick Answer: During your first month on GLP-1 medication, expect: Week 1-2: mild nausea and decreased appetite as your body adjusts. Week 3-4: side effects improve, weight loss becomes noticeable (typically 2-5 lbs). Most patients lose 4-8 lbs in the first month. Drink plenty of water, eat small frequent meals, and focus on protein.

Your First Month: What to Expect

Starting GLP-1 medication is an exciting step toward your weight loss goals. Here's a detailed guide to what you can expect during your first four weeks.

Week 1: Getting Started

What Happens

  • You'll receive your medication with detailed instructions

  • Your body begins adjusting to the medication

What You Might Feel

  • Mild nausea - usually manageable and temporary
  • Decreased appetite - you may notice eating less naturally
  • Some fatigue - your body is adjusting

Tips for Week 1

  • Take your injection at the same time each week
  • Eat smaller, more frequent meals
  • Stay well-hydrated (64+ oz water daily)
  • Avoid fatty, greasy foods that can worsen nausea
  • Keep crackers or ginger tea on hand for nausea

Week 2: Adjustment Continues

  • Possible mild constipation
  • Energy levels stabilizing

Tips for Week 2

  • Continue eating small, frequent meals
  • Add fiber-rich foods to prevent constipation
  • Don't force yourself to eat if not hungry
  • Listen to your body's hunger signals

Week 3: Finding Your Rhythm

What Happens

  • Most people are well-adjusted by now
  • Side effects significantly reduced
  • Weight loss becoming noticeable
  • Eating patterns changing naturally

What You Might Feel

  • More comfortable with the medication
  • Noticing clothes fitting differently
  • Better energy levels
  • Less food "noise" in your mind

Tips for Week 3

  • Start or continue exercise routine
  • Track your progress (weight, measurements, how you feel)
  • Celebrate non-scale victories

Week 4: Seeing Results

What Happens

  • First month complete!
  • Typical weight loss: 4-8 lbs
  • Body well-adjusted to starting dose
  • Provider may discuss dose increase

  • Motivated by early results
  • Establishing new eating habits
  • Ready for next phase

Tips for Week 4

  • Take progress photos
  • Note any questions for your provider
  • Prepare for potential dose increase
  • Reflect on positive changes

Managing Common Side Effects

Nausea

  • Eat slowly and chew thoroughly
  • Avoid lying down after meals
  • Try ginger tea or ginger candies
  • Eat bland foods when feeling nauseous
  • Take medication at bedtime if daytime nausea is bothersome

Constipation

  • Increase fiber intake gradually
  • Drink plenty of water
  • Stay physically active
  • Consider a fiber supplement if needed

Fatigue

  • Get adequate sleep (7-9 hours)
  • Stay hydrated
  • Don't skip meals entirely
  • Light exercise can actually boost energy

Injection Site Reactions

  • Rotate injection sites (abdomen, thigh, upper arm)
  • Let medication reach room temperature before injecting
  • Apply ice before injection if sensitive
  • Clean area with alcohol and let dry

When to Contact Your Provider

Reach out to your care team if you experience:

  • Severe nausea or vomiting that doesn't improve
  • Signs of dehydration
  • Severe abdominal pain
  • Signs of allergic reaction
  • Any concerns that worry you

What NOT to Do

  • Don't skip meals entirely - aim for smaller portions, not starvation
  • Don't ignore severe side effects - contact your provider
  • Don't get discouraged by slow weeks - weight loss isn't linear
  • Don't compare your results to others - everyone's journey is different
  • Don't stop medication suddenly - talk to your provider first

Setting Realistic Expectations

First Month Goals

  • Lose 4-8 lbs (individual results vary)
  • Adjust to the medication
  • Establish new eating patterns
  • Build momentum for continued success

What Success Looks Like

  • Feeling in control around food
  • Smaller portions feeling satisfying
  • Energy for daily activities
  • Positive mindset about the journey

Looking Ahead

After your first successful month, you'll likely:

  • Increase to a higher dose (gradual titration)
  • Continue steady weight loss
  • Build on healthy habits
  • See cumulative results over time

Remember: The first month is about adjusting. The real transformation happens over the following months as you continue treatment.
