Weight Loss and Fertility: Understanding the Connection

Maintaining a healthy body weight plays an important role in reproductive health for both men and women. Excess weight can disrupt hormone levels, interfere with ovulation, and reduce sperm quality, making conception more difficult. Being underweight may also affect hormone production and menstrual regularity.

In women, obesity is often linked with irregular cycles, ovulation issues, and conditions such as Polycystic Ovary Syndrome, which can impact fertility. In men, it may lower testosterone levels and affect sperm health.

The key message is that even modest, sustained weight loss can improve hormonal balance and support better fertility outcomes. In some cases, medically supervised options like Bariatric Surgery may be considered to support long-term weight management and reproductive health.

Mini Gastric Bypass vs Gastric Bypass – Which Procedure Suits You Best?

Mini Gastric Bypass (MGB) and Roux-en-Y Gastric Bypass (RYGB) are two effective weight loss surgeries, each offering strong results for patients struggling with obesity. Understanding how they differ helps you make a confident and informed decision.

Who Is Suitable for These Surgeries?

At our Melbourne clinic, suitability for mini gastric bypass surgery in Melbourne or the traditional gastric bypass is generally based on:

A BMI over 35, or 30+ with an obesity-related condition such as diabetes or sleep apnoea

A history of unsuccessful non-surgical weight loss

Willingness to commit to long-term lifestyle and dietary changes

Mini gastric bypass is often chosen for its simpler surgical approach and shorter operation time.

Roux-en-Y gastric bypass is often the preferred option for patients with severe or persistent reflux, especially when long-term, well-established clinical outcomes are a key consideration.

Who May Require Additional Assessment?

Some individuals may need further evaluation before either procedure, including those with uncontrolled medical issues, untreated psychological conditions, alcohol dependence, or difficulty committing to follow-up care. Long-term vitamin supplementation and routine monitoring are essential after both procedures.

Why Personalised Care Matters

Working with an experienced bariatric specialist ensures that every stage from preparation to long-term aftercare is personalised to your needs. Our multidisciplinary team includes:

A dietitian to guide your nutritional plan

A habits and transformation coach to help build healthy routines

Preparing for Anti-Reflux Surgery: Preparation and Recovery Essentials

If you suffer from persistent acid reflux that isn’t relieved by lifestyle changes or medication, anti-reflux surgery may be a suitable option. This surgery strengthens the valve between your stomach and oesophagus to prevent stomach acid from flowing back, reducing symptoms and improving your quality of life.

Dr. Niruben Rajasagaram, a trusted specialist in Melbourne, offers laparoscopic fundoplication surgery, a minimally invasive procedure where the upper part of the stomach is wrapped around the oesophagus to reinforce the valve.

Who is a candidate for anti-reflux surgery?Surgery may be recommended if you have chronic GERD symptoms not controlled by medication, complications like oesophagitis or Barrett’s oesophagus, or a large hiatal hernia.

What to expect:Before surgery, you’ll undergo tests such as endoscopy and pH monitoring. The procedure is performed under general anaesthesia and usually takes 1–2 hours. Hospital stay is typically 1–2 days, with most patients resuming normal activities within 1–2 weeks. Your diet will gradually progress from liquids to solids as you recover.

Benefits include:

Long-term relief from reflux symptoms

Reduced need for medication

Prevention of future complications

Gastric Sleeve vs Gastric Bypass: Which Weight Loss Surgery Fits Your Goals?

Thinking about weight loss surgery in Melbourne? Gastric sleeve and gastric bypass are two standard options. Understanding the differences can help you choose the best procedure for your health goals.

1. Understanding the Procedures

Gastric Sleeve Surgery: This procedure removes a large portion of the stomach, leaving a smaller, sleeve-shaped stomach. It helps you feel full sooner and may reduce hunger by affecting hunger-related hormones.

Gastric Bypass Surgery: This surgery creates a small stomach pouch and reroutes the small intestine to this pouch. It limits how much you can eat and reduces calorie absorption, leading to significant weight loss.

2. Comparing Benefits and Considerations

Gastric Sleeve:

Simple procedure with a shorter recovery time

Lower risk of nutrient deficiencies

Steady weight loss

Gastric Bypass:

More complex procedure

Higher risk of nutrient deficiencies

Significant weight loss

3. Making the Right Choice

Choosing between the gastric sleeve and bypass depends on various factors, including your health conditions, weight loss goals, and lifestyle preferences. Consulting with an experienced bariatric surgeon in Melbourne can provide personalised advice to help you make an informed decision.

How to Get Ready for Gastric Sleeve Surgery – A Step-by-Step Guide

Thinking about getting gastric sleeve surgery in Melbourne? You’re not alone. It’s one of the most common weight loss surgeries today, and it’s helped many people live healthier, happier lives.

But before the surgery, preparation is key. Being mentally, physically, and diet-wise ready will make your recovery smoother and increase your chances of success.

Here’s a simple guide to help you prepare:

1. Get Mentally Ready

This surgery is a big step, so it’s important to prepare your mind first.

Understand the process: Read about what the surgery involves, how long recovery takes, and how life will change after.

Set realistic goals: Remember, the surgery is just a tool. You’ll still need to eat right and stay active.

Talk to others: It helps to speak with people who’ve already had the surgery or join support groups in Melbourne or online.

2. Start Getting Physically Ready

Your body needs to be in the best shape possible before surgery.

Medical tests: Your surgeon may ask for blood work, scans, or other checks to ensure you’re fit for surgery.

Move more: Start walking or doing light exercises to improve fitness levels.

Stop smoking: If you smoke, try to quit. Smoking can slow down healing and increase risks.

3. Make Diet Changes Early

The way you eat before surgery can affect how you heal and lose weight after.

Eat smaller meals: Start practicing portion control now.

Focus on protein: Choose high-protein foods and cut back on sugar and carbs.

Drink more water: Avoid fizzy drinks and sugary juices. Water is your best friend.

Talk to a dietitian: Many Melbourne surgeons work with experienced dietitians who can guide your meal plan.

Weight Loss Surgery Options in Melbourne: Your Guide to a Healthier Future

If you’re struggling with obesity and have found that diet and exercise aren’t enough, weight loss surgery might be the answer. In Melbourne, there are several effective bariatric procedures available that can help you achieve lasting weight loss and improve your overall health.

Key Weight Loss Surgery Options:

Gastric Sleeve Surgery:This procedure involves removing a large portion of your stomach to reduce its size. It helps you feel full sooner, limits food intake, and promotes significant weight loss over time.

Gastric Bypass Surgery:Also known as Roux-en-Y gastric bypass, this surgery creates a small stomach pouch and reroutes the digestive system. It not only limits food intake but also reduces calorie absorption, making it a powerful tool for long-term weight management.

Laparoscopic Mini Gastric Bypass:A minimally invasive alternative that offers similar benefits to the traditional bypass but with a simpler procedure and faster recovery. This option is ideal for patients looking for an effective yet less complex surgery.

Gastric Balloon Surgery:For those not yet ready for surgical intervention, the gastric balloon is a non-surgical, temporary option that helps control hunger and reduce food intake, kickstarting your weight loss journey.

Each procedure comes with its own set of benefits and considerations. The best option for you depends on factors such as your Body Mass Index (BMI), overall health, and weight loss goals. Consulting with an experienced bariatric surgeon is essential to determine which surgery will work best for your unique needs.

Everything You Need to Know About Gastric Bypass Surgery: A Simple Guide

Gastric bypass surgery is one of the most popular weight loss surgery options available today. In simple terms, it is a procedure that helps people with severe obesity lose weight by reducing the size of the stomach and rerouting the digestive system. This not only limits the amount of food you can eat but also changes how your body absorbs calories.

What Is Gastric Bypass Surgery?

Gastric bypass surgery—often referred to as Roux-en-Y gastric bypass—involves creating a small stomach pouch and bypassing part of the small intestine. By doing this, the surgery helps reduce food intake and limits calorie absorption. It is an effective way to help people lose a significant amount of weight over time.

How Does It Work?

During the surgery, a surgeon uses laparoscopic techniques, which means small incisions and specialised tools are used to perform the procedure. This minimally invasive approach results in:

Less pain after surgery

Shorter recovery time

Minimal scarring

The reduced stomach size means you feel full faster, and the rerouting of your intestines helps your body process food differently, leading to long-term weight loss.

Who Can Benefit from Gastric Bypass?

Gastric bypass surgery is generally recommended for individuals who:

Have a high Body Mass Index (BMI) along with obesity-related conditions like type 2 diabetes, high blood pressure, or sleep apnea.

Have not achieved long-term weight loss success through diet and exercise alone.

Are looking for a lasting solution to improve overall health and quality of life.

Benefits and Considerations

Benefits:

Significant Weight Loss: Helps reduce excess weight over the long term.

Health Improvements: Often leads to the remission of obesity-related conditions such as diabetes and high blood pressure.

Enhanced Quality of Life: Many patients experience increased energy levels and improved mobility.

Considerations:

As with any surgery, there are risks involved. It’s important to have a thorough consultation with a specialist.

Recovery requires a commitment to a new diet and lifestyle changes to maintain weight loss and overall health.
