Micronutrients & recovery
Adapting bariatric surgery nutritional monitoring protocols (baseline screening, supplementation, periodic testing) to GLP-1RA therapy is recommended to mitigate long-term complications.
Ask your doctor for baseline blood tests for Vitamin D, B12, Iron, Calcium, and Magnesium before or shortly after starting GLP-1 therapy. Repeat these tests annually. Based on results, take a high-quality multivitamin and specific supplements as recommended. This is a proactive step to protect your long-term health.
Adapting elements from these surgical frameworks could offer a pragmatic starting point... Baseline screening for key deficiencies, early correction of low vitamin or mineral levels, routine supplementation strategies similar to SG protocols that exist already, and periodic reassessment during treatment may help prevent avoidable complications.
Why this rating
Based on strong observational data of deficiencies and established efficacy of monitoring in surgery, though direct RCT evidence for GLP-1 monitoring is lacking.
