Reading Your Results
When your lab results reveal:
- Iron deficiency: Frequently causes shedding. Supplement with ferrous sulfate and recheck in 2-3 months
- Low vitamin D: Associated with poor skin healing. Supplement 2000-5000 IU/day
- Zinc deficiency: Slows wound healing. Supplement zinc picolinate
- Abnormal thyroid: Can cause skin changes in addition to GLP-1 effects
- Low albumin: Indicates poor protein intake — essential to improve before any surgery
Recommended Timeline
- Before starting GLP-1: Optimal but frequently not done
- {3 months on GLP-1}: Initial monitoring for deficiencies
- {6 months on GLP-1}: Follow-up especially if symptoms are present
- Before any procedure: Complete testing to ensure surgical readiness
- Annually: Regular surveillance while on GLP-1 medication
Next Steps
Share your lab results to both your healthcare providers:
- Weight loss doctor: Can optimize treatment plan
- Skin specialist: Uses results to inform skin/hair treatment
- Plastic surgeon: Requires adequate lab values before approving operations
Frequently Asked Questions
Does insurance cover lab work for cosmetic concerns?
Several of these tests are typically covered when ordered by your physician for health monitoring. Your doctor can requisition them as part of health screening on GLP-1 therapy.
What is the most important lab test for hair loss on GLP-1?
