Preoperative Labs & Medical Clearance for Liposuction
Preoperative testing is not paperwork — it is how your surgical team confirms you can tolerate anesthesia and body-contouring surgery safely. This page describes the standard labs, when specialty clearances are required, medications to hold, and how to plan the pre-op window so nothing derails your scheduled date.

| Standard labs | CBC, BMP, PT/PTT/INR, β-hCG (women), HbA1c (screen) |
|---|---|
| ECG | Age ≥50, cardiac risk factors, or as anesthesia requires |
| Chest X-ray | As clinically indicated |
| Timing | Labs within 30 days; ECG within 3–6 months |
| Medical clearance letter | From PCP or relevant specialist |
Standard preoperative panel
- CBC — screens for anemia and platelet adequacy
- Basic metabolic panel — electrolytes and renal function
- Coagulation panel (PT/PTT/INR) — bleeding risk
- Pregnancy test where applicable
- Hemoglobin A1C — diabetes screening; poorly controlled diabetes raises infection risk
- Type and screen for larger cases
Specialty clearances by risk profile
- Cardiology — known cardiac disease, cardiac medications, exertional symptoms, older adult
- Pulmonology — significant COPD, obstructive sleep apnea, smoking history
- Endocrinology — poorly controlled diabetes or thyroid disease
- Hematology — bleeding or clotting history, on anticoagulation
Medications typically held
- Aspirin, NSAIDs (ibuprofen, naproxen) — 7–10 days pre-op
- Prescription anticoagulants — per prescriber schedule
- Fish oil, vitamin E, garlic, ginkgo — 2 weeks pre-op
- GLP-1 medications — weekly formulations ~7 days per current anesthesia guidance
- Hormonal contraception / HRT — discussion of DVT-risk timing
Do NOT stop these without prescriber input
- Antihypertensives, cardiac medications
- Insulin or oral diabetic medications (may be dose-adjusted)
- Antidepressants, anti-anxiety medications
- Antiseizure medications
Anesthesia
This entire page is anesthesia-adjacent — labs and clearances exist to make general anesthesia safer.
Recovery timeline
- 6 weeks pre-opBegin nicotine cessation and hold supplements.
- 3–4 weeks pre-opComplete labs, ECG, and clearance visits.
- 7–10 days pre-opHold NSAIDs; adjust GLP-1 per plan.
- 24 hours pre-opClear-liquid diet transition, NPO after midnight.
Risks and complications
- Cancellation of surgery for missing clearance
- Perioperative bleeding from held-supplement error
- Anesthesia complications from undisclosed medications
Every surgical procedure carries risk. A complete personalized risk discussion is part of every consultation.
Cost factors
- Lab and imaging fees (often billed to insurance)
- Specialty consultation fees

Questions to ask your surgeon
- What exact labs do you require and by when?
- Do I need cardiology or pulmonology clearance?
- Which of my current medications need to be held?
- How do we manage my GLP-1 hold?
Frequently asked questions
- What standard labs are ordered?
- For elective liposuction under general anesthesia, expect a CBC (complete blood count), basic metabolic panel, coagulation panel (PT/PTT/INR), pregnancy test where applicable, and often a hemoglobin A1C for diabetic screening.
- When is an ECG required?
- Standard for patients over 50, patients with cardiac history, hypertension, or diabetes, and for larger-volume operations. Many surgeons also request an ECG for any patient scheduled for general anesthesia regardless of age.
- Chest X-ray?
- Ordered when clinically indicated — smoking history, chronic pulmonary conditions, older adults, or larger operations. Not routine for young healthy patients.
- What is a medical clearance letter?
- A written statement from your primary care physician or a relevant specialist confirming you are cleared for elective surgery under general anesthesia. It reviews your history, medications, and any risk factors.
- Do I need cardiac clearance?
- If you have known cardiac disease, take cardiac medications, have exercise-limiting symptoms, or are over 65 with cardiac risk factors, a cardiology clearance (often with stress echo or nuclear study) is standard.
- How current do labs need to be?
- Typically within 30 days of surgery. ECG and specialty clearances within 3–6 months if no interval change.
- Medications to stop before surgery?
- Blood thinners (aspirin, NSAIDs, prescription anticoagulants), fish oil, vitamin E, herbal supplements, and — increasingly — GLP-1 medications on the anesthesia-society schedule. Never stop prescription medications without your prescriber's direction.
