Are you curious about the role of GLP-1 medications in your post-surgery journey?

GLP-1 medications and weight loss surgery can work together to enhance weight loss and improve overall health. After surgery, these drugs can help sustain weight loss by suppressing appetite, increasing fullness, and improving blood sugar control.

They may make it easier to stick to smaller portions, and in some cases, they are prescribed 1–5 years post-surgery to aid in long-term weight management and prevent regain.

It is important, however, that you speak with your main healthcare provider to ensure this is safe for you.

Liquid calories are calories consumed through drinks like juice, soft drinks, milkshakes, alcohol, meal replacements, and milky coffees.

While protein shakes can be helpful for hydration and protein needs during the early stages of recovery after bariatric surgery, it’s important to stay mindful as time goes on. Because liquids pass quickly through your stomach without making you feel full, these calories can add up fast, potentially leading to poor weight loss or even weight regain.

Drinks high in sugar and fat such as thickshakes, are more likely to trigger dumping syndrome. For the best results, focus on low-sugar and low-fat beverages, and remember that protein-rich drinks are generally only needed if you aren’t hitting your protein goals through food alone.

For Exercise Right Week, let’s talk about the real secret to long-term success after weight loss surgery: exercise enjoyment.

If you view movement as a chore or a punishment, it won’t stick. But when you find activities that genuinely bring you joy, consistency follows naturally.

Post-surgery exercise isn't about breaking records, it's about celebrating what your body can do. Start small, listen to your body as it heals and focus on the incredible boost to your mood and energy.

Recovery after weight loss surgery is a journey, and staying hydrated is the single most important task on your daily to-do list. Because your stomach capacity is significantly smaller, it is much easier to become dehydrated if you aren’t proactive.

Proper hydration doesn't just keep thirst away, it’s essential for:

🔹Faster healing and tissue repair
🔹 Preventing constipation
🔹 Avoiding "brain fog," fatigue and headaches
🔹 Reducing the risk of kidney stones and hospital readmission

Aim for 1.5L to 2.0L of total fluids daily. Remember to sip consistently throughout the day and keep your fluids separate from your meals to maximise your intake.

Gallstones and gallbladder inflammation are common conditions that can cause significant discomfort and digestive issues.

I specialise in Laparoscopic Cholecystectomy (gallbladder removal), a "keyhole" procedure that typically allows for a faster recovery and a quicker return to your normal diet and activities.

If gallbladder issues are impacting your quality of life, a surgical assessment can help determine if a minimally invasive procedure is the right solution for you.

What happens after the "I do"? No, not a wedding—we’re talking about the commitment to weight loss surgery!,

Most people ask about the surgery itself, but what they really want to know is: “What will my life actually look like six months from now?”

Weight loss surgery is a profound reset for your metabolism. It’s about quietening the "food noise," regaining your energy, and often, saying goodbye to medications for sleep apnea or blood pressure. It’s not just about losing weight, it’s about gaining your life back.

Every journey is unique, and the first step is an informed conversation. Book your consultation with Dr Peter Hamer today by calling (02) 4380 8404.
