A common concern we hear is this – Do I need to lose weight with injections first before I can be considered for bariatric surgery?

In many cases, the answer is ‘No’.

You Do Not Always Need Injections Before Surgery

Patients with BMI above 45, and particularly those above 50, are sometimes told they must reduce weight before surgery is even discussed. This can lead to months or even years spent trying medications first.

At Blackrock WeightCare, we regularly assess and treat high BMI and complex cases. Surgery is not automatically ruled out because your BMI is high. In fact, procedures such as SADI-S are specifically designed for patients who require a stronger metabolic effect.

If surgery is clinically appropriate, it can be planned safely without asking you to invest time and money into injections first.

Each case is assessed on its own merits.

When Injections May Be Helpful

That said, weight loss injections can sometimes be useful.

They may help:

• Improve blood sugar control before surgery
• Reduce liver size
• Optimise medical conditions
• Support short-term weight reduction in selected cases

But this is strategic and individual. It is not a requirement for everyone.

Injections should never be viewed as a mandatory first step before surgical assessment.

High BMI Is Not an Automatic Barrier

Severe obesity often comes with additional conditions such as Type 2 diabetes, sleep apnoea, joint disease or cardiovascular risk. These patients need specialist input, not delay.

At Blackrock WeightCare, complex and high BMI patients are routinely assessed by Mr William Robb, an experienced Upper GI and Robotic Bariatric Surgeon. Careful evaluation determines:

• Whether surgery is safe now
• Whether optimisation is required first
• Which procedure offers the best long-term outcome

In many cases, metabolic surgery such as Gastric Sleeve or SADI-S provides more durable weight loss and stronger metabolic improvement than injections alone.

Why Expert Assessment Matters First

Starting injections without specialist advice can lead to:

• Modest short-term weight loss but no long-term plan
• Weight regain after stopping medication
• Delayed definitive treatment
• Additional financial cost

Obesity is a chronic disease. The treatment pathway should be planned properly from the outset.

An expert consultation allows you to understand:

• Whether injections are appropriate
• Whether surgery is the more effective option
• Whether a combined approach makes sense
• What is safest given your BMI and medical history

The right decision depends on your health, not on trends.

The Bottom Line

Weight loss injections can play a really positive role in obesity treatment. They are very useful tools in well selected and educated patients.

But you do not need to “prove yourself” with injections before being considered for surgery.

If you have a high BMI or complex medical history, the first step should always be specialist assessment. That way, you avoid unnecessary delay and move forward with a clear plan. Surgery and medication are very often complementary in the treatment of obesity – rather than it being the case of one or the other.

SADI-S is one of the more powerful bariatric procedures available and is designed for people with severe obesity who need more than a standard sleeve alone.

What SADI-S Means in Practical Terms

SADI-S combines a sleeve gastrectomy with a bypass of part of the small intestine. The stomach is reduced in size, and food passes further down the intestine, which creates a strong metabolic effect.

This tends to result in:

• Greater overall weight loss in higher BMI patients
• Strong improvement in blood sugar control
• Reduction in cardiovascular risk factors
• Better long-term outcomes in patients with BMI above 45

The procedure is carried out by Mr William Robb using advanced robotic and minimally invasive surgical techniques, with a focus on precision and patient safety.

Who is it Suitable For

SADI-S is generally considered for:

• Patients with BMI over 45
• Severe obesity with significant metabolic disease
• Poorly controlled Type 2 diabetes
• Patients who require substantial and sustained weight loss

This is not a routine operation for lower BMI ranges. It is chosen carefully, based on clinical need and long-term goals.

What to Expect Before Surgery

The preparation is thorough. You can expect:

• A detailed surgical consultation
• Full medical assessment and blood tests
• Review of medications and current health conditions
• A structured pre-operative diet plan
• Clear explanation of risks and long-term responsibilities

An important part of the process is psychological evaluation. This is not a test to pass or fail. It is there to ensure you are emotionally prepared for the changes ahead. Surgery alters eating patterns, routines and coping mechanisms. Understanding your relationship with food, stress and lifestyle habits helps build a safer and more sustainable outcome.

This step is about support, not judgement.

What to Expect Around the Time of Surgery

SADI-S is carried out under general anaesthesia. Most patients stay in the hospital for 1-2 days.

After surgery, you can expect:

• Early mobilisation
• A gradual transition from liquids to soft foods
• Smaller portion sizes
• Rapid early weight loss
• Regular contact with the clinical team

The first few weeks require adjustment. Energy levels can fluctuate as your body adapts.

What to Expect in the Months After

Weight loss usually progresses steadily over 12 to 24 months. Many patients experience:

• Significant total body weight loss
• Improved diabetes control, sometimes with reduced medication
• Lower blood pressure
• Less joint pain
• Improved sleep quality
• Greater mobility

Results vary, but meaningful health improvement is the goal.

Because part of the intestine is bypassed, lifelong vitamin and mineral supplementation is required. Regular blood monitoring forms part of follow-up care. The structured aftercare programme at Blackrock WeightCare supports patients for the long term, not just the immediate post-operative period.

Accessing SADI-S Surgery in Ireland for High BMI Patients from Northern Ireland

Patients in Northern Ireland with very high BMI can face limited access to advanced bariatric procedures or long waiting times. Choosing treatment in Dublin at Blackrock WeightCare allows surgery and follow-up to take place within Ireland, with regular communication with your GP and ongoing monitoring close to home.

Many patients prefer this to travelling abroad, where long-term follow-up and nutritional supervision can be difficult to maintain.

SADI-S is a serious decision. It requires commitment and follow-through. It is also one of the most effective tools available for treating severe obesity and its related conditions.

If you would like to explore whether SADI-S is suitable for you, you can enquire through our website or speak directly with our team on 01 255 2479.
