The Body Mass Index (BMI) calculator is a tool that measures an individual's body fat based on their height and weight. It's a widely used method to categorize individuals into various weight statuses, ranging from underweight to obese. The BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters (kg/m²).
In the context of gastric surgeries, the BMI calculator plays a crucial role for several reasons -
Eligibility Criteria - Many surgical procedures, especially those related to weight loss like gastric bypass or sleeve gastrectomy, have specific BMI criteria for eligibility. Typically, these surgeries are recommended for individuals with a BMI of 40 or higher (indicating severe obesity) or those with a BMI of 35 to 39.9 with obesity-related health conditions, such as type 2 diabetes, high blood pressure, or severe sleep apnoea.
Health Risk Assessment - A high BMI can indicate a higher risk of developing various health issues, including heart diseases, diabetes, and certain types of cancer. Surgeons use the BMI to assess the potential risks associated with the surgery and to tailor the procedure to minimize these risks.
Tailoring the Surgery - The BMI helps in planning the specifics of the surgical procedure. It can influence the choice of surgery and its complexity. For instance, patients with a very high BMI might undergo a two-step surgical process for safer and more effective outcomes.
Monitoring Progress - Post-surgery, the BMI calculator is used to monitor the patient's progress in terms of weight loss and improvement in obesity-related health conditions. This helps in evaluating the success of the surgery and guiding any necessary adjustments in the patient's post-operative care and lifestyle changes.
In essence, the BMI calculator is an indispensable tool in the realm of gastric surgeries, facilitating informed decision-making, ensuring patient safety, and optimizing surgical outcomes. At DHI, we emphasize the importance of comprehensive assessments like the BMI to ensure our patients are receiving the most suitable and effective treatments for their journey towards a healthier future. Our commitment to patient-centric care ensures that each individual's path to health is tailored to their unique needs, leveraging advanced medical technology and a deep understanding of the challenges they face, including long waiting times and accessibility issues.
The gastric bypass is one of the most effective and widely performed bariatric operations worldwide.
It is often called the "sleeve" for short, is a weight loss procedure where the surgeon removes a large portion of your stomach, leaving behind a small, banana-shaped stomach. With this smaller stomach, you feel full faster when you eat, so you naturally eat less. It helps people lose weight because they consume fewer calories. This surgery can also improve certain health issues associated with obesity, like diabetes and high blood pressure. It's a permanent change to your stomach size, but it doesn't reroute your digestive system like some other weight loss surgeries.

Gastric Bypass Surgery: From 20 to 10 stone
Maureen soared to 20 stone after having four children, so she elected to go for Gastric Bypass surgery to help her slim.
"It had got to the stage where I felt like a freak and was losing my confidence. I knew I had to do something to change my body before it was too late."
"It has changed my life," says the delighted Gastric Bypass client "I'm going to get a bikini and I won't hesitate to wear it. And I'll have no qualms about going topless either, which is something I never thought I'd say.”
"And I will wear make-up now. Before I owned just one lipstick and a five-year-old mascara - and I can't remember the last time I used that. I didn't see the point, I thought it was like trying make a silk purse out of a sow's ear so I didn't bother. It will be lovely to go on holiday and not be worrying about how I look.”
"Before all this I wouldn't have dreamed of showing any part of my body, now I'll have no problem with it all. I feel like a different person - the person I always knew I could be.“
"It's about so much more than looks," she says. "I feel good and that is giving me confidence. I'm 5ft 10ins, which is fairly tall, but I used to try and hide away. Now I stand up straight and walk tall because I feel brave enough to do that. If I'm in a group these days I will come forward and join in. And I no longer get mistaken for a pensioner!“
"Looking down at her brand-new body again, she adds with a smile: "It really is one of the best things that has ever happened to me.” “I feel pretty and feminine,” she grins. “It still takes a bit of getting used to!”
