Fatigue on GLP-1: Quick Tips to Manage It

This memo offers essential, short wisdom gathered from both social forums and scientific studies. If you're struggling with fatigue while on GLP-1 medications, you'll find practical tips here to help manage and reduce exhaustion, based on real-world experience and research.

Basic Strategies

• Nutrition focus: Ensure adequate protein intake (1.2-1.6g per kg body weight)

• Hydration: Drink 2-3 liters of water daily; dehydration worsens fatigue

• Sleep hygiene: Maintain consistent sleep schedule with 7-8 hours nightly

• Vitamin levels: Ask doctor to check B12, iron, vitamin D, and thyroid function

• Blood sugar monitoring: Check glucose levels when experiencing energy dips

• Meal timing: Space meals evenly throughout day to stabilize energy

• Activity pacing: Balance activity with rest; don't overexert on "good days"

By Severity Level

Mild Fatigue

• Morning routine: Brief exposure to sunlight within first hour of waking

• Gentle movement: Short 10-minute walks when feeling tired

• Strategic caffeine: Small amounts before 2PM (if not contraindicated)

• Cold shower: Brief cold exposure can increase alertness

• Power naps: Limit to 20 minutes to avoid disrupting nighttime sleep

• Breathing exercises: Deep breathing techniques to increase oxygen levels

Moderate Fatigue

• Medication timing: Take GLP-1 before bed to sleep through initial effects

• Energy mapping: Track energy levels to identify patterns and plan activities

• Supplementation: Consider CoQ10 or B-complex with doctor's approval

• Protein shakes: Easy nutrition when too tired to prepare meals

• Stress reduction: Meditation, mindfulness, or gentle yoga

• Electrolyte balance: Add electrolytes to water, especially if experiencing diarrhea

Severe/Persistent Fatigue

• Medical evaluation: Rule out anemia, thyroid issues, sleep apnea

• Medication adjustment: Discuss dosage reduction with doctor

• Rest periods: Schedule mandatory rest breaks throughout day

• Adaptogens: Herbs like rhodiola or ashwagandha with doctor's approval

• Physical therapy: Graduated exercise program designed for fatigue

• Alternative GLP-1: Consider switching to different GLP-1 medication

Lifestyle Adaptations

• Activity prioritization: Identify essential activities; delegate or postpone others

• Energy conservation: Sit instead of stand when possible; simplify routines

• Strategic scheduling: Plan important tasks during peak energy periods

• Meal preparation: Batch cook and freeze portions for low-energy days

• Social support: Ask for specific help with energy-demanding tasks

• Work accommodations: Discuss flexible schedules or breaks if needed

Warning Signs (Consult Healthcare Provider)

• Fatigue that completely interferes with daily functions

• Fatigue with dizziness, shortness of breath, or chest pain

• Sudden onset of extreme fatigue

• Fatigue with significant weight loss beyond expected GLP-1 effects

• Signs of dehydration (dark urine, excessive thirst, dizziness)

• Fatigue with signs of depression or anxiety

• Unrefreshing sleep despite adequate time in bed

Remember that while some fatigue can occur with GLP-1 medications, particularly during the adjustment period, severe or persistent fatigue should be evaluated by a healthcare professional. Fatigue can also be a sign of nutritional deficiencies, dehydration, or low blood sugar, all of which need attention.
