When 100 KG+ begins affecting more than your weight.
Poor sleep. Rising blood sugar. Knee and back pain. Breathlessness. Reduced mobility. Repeated weight regain. Severe obesity can gradually become a medical and everyday-life burden.

When does weight above 100 kg become a medical concern?
The important question is not simply how much somebody weighs. It is how much obesity has started affecting health, movement and everyday life.
Two people can weigh exactly the same and experience very different levels of obesity-related disease.
Severe obesity may gradually appear as poor sleep, rising blood sugar, breathlessness, knee or back pain, reduced mobility, fatty liver disease and repeated difficulty maintaining major weight loss.
This is why obesity treatment should not be reduced to the instruction to simply “eat less and move more.”
At 100 KG+, the goal is not simply
to become lighter.
The goal is to become
less burdened by obesity.
Better metabolic health. Better mobility. Better daily function. Fewer obesity-related limitations—where clinically achievable.
Severe obesity can gradually make ordinary life more difficult.
Not because somebody wants less from life, but because ordinary activities begin demanding more from the body.
Does weighing more than 100 kg mean you need weight loss surgery?
No. A person weighing 105 kg at 190 cm and another person weighing 105 kg at 155 cm have very different BMI profiles.
Bariatric and metabolic surgery decisions consider BMI together with obesity-related disease, previous treatment, nutritional status, medical history and individual surgical risk.
BMI starts the conversation. It does not make the decision by itself.
Calculate your BMI
Educational screening only. BMI alone does not establish suitability for surgery.
Lifestyle still matters. Severe obesity may need more than lifestyle alone.
Nutrition, physical activity, sleep and behavioural change remain important throughout obesity treatment.
Severe obesity, however, is influenced by appetite regulation, satiety signalling, metabolic adaptation, sleep, hormones, insulin resistance and previous weight-loss history.
After major weight loss, biological mechanisms can favour weight regain in some people.
That does not automatically mean surgery is required. But repeated inability to maintain substantial weight loss should not simply be interpreted as a lack of willpower.
When does weight loss surgery become a serious medical conversation?
Surgery is not an operation for everybody who wants to lose weight. It becomes relevant when the severity of obesity and its health burden justify discussing surgical treatment alongside risks and long-term care.
Gastric Sleeve Surgery
Also called laparoscopic sleeve gastrectomy. A substantial portion of the stomach is removed, leaving a narrower gastric sleeve.
Roux-en-Y Gastric Bypass
Gastric bypass creates a smaller stomach pouch and reroutes part of the small intestine, producing gastrointestinal and metabolic effects.
One-Anastomosis Gastric Bypass
Also called OAGB or mini gastric bypass, this is another established bariatric and metabolic procedure.
Revisional Bariatric Surgery
Patients who have previously undergone bariatric surgery may need evaluation for weight recurrence, reflux, anatomical problems or inadequate treatment response.
Why does planning matter more when a patient weighs 120, 140 or 160 kg?
Very high BMI can increase peri-operative complexity. The operation itself is only one part of a complete bariatric programme.
Severe obesity and sleep apnoea can influence anaesthetic planning.
Glucose and medication management may require careful peri-operative review.
Individual risk assessment and preventive measures are important.
Mobilisation and respiratory planning may be particularly relevant during recovery.
Very high weight alone does not dictate which operation should be performed.
This is not Dr Mohit Bhandari's first conversation with Kenya.
The photographs below document previous interactions in Nairobi. They demonstrate continuity of engagement and do not imply that every person pictured underwent bariatric surgery or achieved a particular clinical result.
Why surgeon experience matters when obesity is complex
The surgeon's role begins before the operation itself.
Dr Mohit Bhandari works in bariatric, metabolic, minimally invasive, robotic and revisional obesity surgery.
In higher-BMI patients, clinical decision-making includes determining whether surgery is appropriate, selecting the right procedure, evaluating metabolic disease and surgical risk, and planning postoperative nutrition and follow-up.
24 September
The date should not rush the decision. It should help patients already considering bariatric surgery complete evaluation and treatment planning beforehand.
