While there is no physical dependence, sudden discontinuation can lead to rapid weight regain and metabolic rebound
Standard baseline labs: Hemoglobin A1C (required for diabetes pathway, recommended for weight management pathway) Fasting lipid panel (total cholesterol, LDL, HDL, triglycerides) Comprehensive metabolic panel (kidney function, liver function, electrolytes) Thyroid-stimulating hormone (TSH) Lipase (baseline pancreatic enzyme level) Additional testing in specific situations: Calcitonin level if family history of medullary thyroid carcinoma (not routine, only if high-risk) Pregnancy test for women of childbearing age (tirzepatide is contraindicated in pregnancy) Gallbladder ultrasound if history of gallstones The lab work serves three purposes: confirm comorbidities (A1C for prediabetes, lipid panel for dyslipidemia), establish baseline values for monitoring, and screen for contraindications (severe kidney disease, active pancreatitis)
This was an adaptation of the protocol described by Neilson and collaborators ( In our case, having used a medium with poor ingredients, with respect to the protocol described in literature ( in vivo study was performed in two phases, first using a wild-type mouse ( Mus musculus ) model, C57BL/6 (FMO3 +/+ ) female mice, where TMAO levels in the blood were measured 3 h after the administration of the inhibitor and 2 hours after the administration of choline orally
In practice, there are a lot of centres that dont have the funding to do that
