After trying every diet and “quick fix,” you’ve made a brave, life-changing decision: to take control of your health through bariatric surgery.
This isn’t another short-term plan. It’s a long-term commitment to changing your relationship with food, movement, and overall wellbeing.
Many bariatric practices use a structured six-week countdown to help you feel prepared and supported. Below is a clear, step-by-step guide to help you get ready for surgery—and for the healthier life that follows.
Week 1: Meet your bariatric surgeon
Bring your GP referral to your first consultation (if your country’s system requires one). In many healthcare systems, specialist referrals are time-limited, so check validity dates and any requirements before your appointment.
At this first visit, your surgeon will:
- Review your medical history and current health risks
- Discuss your goals (weight loss, mobility, fertility, blood sugar control, sleep, joint pain, etc.)
- Explain the surgical options and what outcomes are realistic
- Confirm whether surgery is appropriate and safe for you
A plan tailored to your goals
Bariatric surgery is not only about weight loss—it’s about improving health and quality of life. Your surgeon will help you understand whether surgery fits your situation and what preparation is needed to reduce risk and improve results.
Week 2: Complete your pre-surgical tests and meet your dietitian
Most patients complete a standard pre-operative screening to ensure they’re medically ready and to identify risks that should be corrected before surgery.
Common tests include
1) Blood tests (often a full panel)
These may include a full blood count, kidney and liver function, electrolytes, and vitamin/mineral levels. Deficiencies and anaemia are common and should ideally be corrected to reduce complications and support recovery.
2) Heart and lung assessment
Depending on your history, you may need an ECG, echocardiogram, or additional cardio testing. Respiratory function tests and sleep studies may be recommended—especially if sleep apnoea is suspected.
3) Gastroscopy (upper endoscopy)
An endoscopy may be done to check for ulcers, polyps, reflux disease (GERD), and other concerns that can influence which bariatric procedure is safest and most suitable. A hiatus hernia may also be identified and sometimes repaired during surgery.
4) Additional specialist reviews (if needed)
People with complex conditions may be referred to an endocrinologist, psychologist/psychiatrist, or other specialists—especially where diabetes, depression/anxiety, or compulsive eating patterns are present.
Dietitian consultation
Most bariatric patients meet a dietitian before surgery and again afterward. Your pre-surgery plan typically includes:
- High-protein, lower-carbohydrate meals
- Clear hydration targets
- A very-low-calorie diet (VLCD) closer to surgery to reduce liver size and improve surgical access
- Starting (and continuing) a vitamin/mineral regimen, because nutrient absorption can change after surgery
It’s normal to feel overwhelmed by the testing and preparation. But this process is designed to make surgery safer and recovery smoother.
Week 3: Start gentle exercise and build steady habits
Even modest movement before surgery can improve fitness, circulation, mood, and confidence—and can reduce risks such as blood clots.
Aim for consistency over intensity. Examples:
- Walking: 5–10 minutes per day, 3–4 times per week, gradually increasing
- Chair or water exercises: helpful if joints are painful
- Stretching or gentle yoga: improves flexibility and reduces tension
- Light resistance work: bands or light weights 2–3 times per week
- Tracking: record minutes, steps, or distance; weigh weekly if advised
The goal isn’t perfection—it’s helping your body re-learn safe movement before the operation.
Week 4: Refine your very-low-calorie diet (VLCD)
If you’ve been prescribed a VLCD, stick closely to the instructions. Common principles include:
- Hydration first: sip fluids slowly throughout the day
- Avoid drinking with meals: often you’ll be asked to wait about 30 minutes after eating before drinking again
- Prioritise protein: base meals/snacks on lean protein to protect muscle
- Avoid high-risk foods and drinks: fried/fatty foods, chips/snacks, sugary drinks, and carbonated drinks—these can worsen nausea and discomfort after surgery and may contribute to “dumping” symptoms in some procedures
Week 5: Get your mind ready with mindfulness
Surgery changes your stomach—mindfulness helps change your habits.
Mindfulness can help you:
- notice hunger and fullness cues
- slow down automatic eating
- reduce emotional eating triggered by stress
- feel calmer and more in control
Try these practical habits:
- Eat without screens or scrolling
- Notice colour, texture, smell, and taste
- Chew slowly and put utensils down between bites
- Check hunger/fullness before and during meals
- Learn the difference between emotional hunger (urgent, craving-driven) and physical hunger (gradual, body-based)
- Start or end meals with a brief moment of gratitude
Week 6 (Part 1): Attend your pre-surgical assessment
By now, your results are usually back. Your surgeon will:
- review your test findings
- confirm your procedure plan
- explain risks, side effects, and expected recovery
- complete consent and discuss costs/financial arrangements
- give medication instructions and pre-op precautions
Important: always tell your care team about all medications and supplements (prescribed, over-the-counter, herbal). Some medicines—such as blood thinners—may need specific timing adjustments before surgery. Smoking cessation is also strongly recommended well before surgery, as it increases surgical and healing risks.
Week 6 (Part 2): Prepare for hospital and recovery at home
Before you leave for hospital
- Confirm surgery date, admission time, and paperwork/online registration
- Ensure all reports and clearances have been shared
- Confirm follow-up appointments and post-op support plans
- Follow fasting instructions exactly
- Arrange someone to drive you home (you generally can’t drive for at least 24 hours after anaesthesia/sedation)
What to pack
- Documents: ID, insurance/medical aid info, admission paperwork, medication list
- Comfort: loose clothing, slippers, lip balm, light robe
- Hygiene: toothbrush, deodorant, face wipes, hairbrush
- Entertainment: chargers, headphones, a book/playlist
- Notebook: questions, instructions, and daily notes
Set your home up for recovery
- Arrange help with meals, cleaning, shopping, and laundry
- Keep essentials within easy reach
- Remove trip hazards (cords, loose rugs)
- Use a sturdy chair with armrests for safer sitting/standing
- Move slowly—don’t rush to stand up or walk
You’re nearly there
Feeling nervous and excited is completely normal. The calm you build before surgery becomes part of the strength you carry after it.
Six weeks ago, you started with questions. Now you have knowledge, structure, and a plan. With the right preparation and support, bariatric surgery can be the beginning of a healthier, more capable life.
