Gastrointestinal cancers can affect vital digestive organs such as the stomach, colon, liver, pancreas, and intestines, often requiring timely diagnosis and specialized treatment. Symptoms may include unexplained weight loss, abdominal pain, bleeding, or changes in bowel habits. Dr. Niranjan P offers comprehensive GI cancer care with advanced surgical techniques, including minimally invasive and laparoscopic oncological procedures for precise tumor removal. His treatment approach is combined with evidence-based medical planning and multidisciplinary care to improve recovery and long-term outcomes.

Diabetic foot complications such as non-healing ulcers, infections, and tissue damage can progress rapidly and increase the risk of severe infection or amputation if untreated. These conditions often arise due to poor circulation and nerve damage associated with diabetes.

Obesity is a complex metabolic condition that, when associated with type 2 diabetes, hypertension, or sleep apnoea, often requires more than lifestyle modification alone to achieve meaningful and sustained improvement. Dr. Niranjan P, Consultant Bariatric and Laparoscopic Surgeon at NiSH Clinic, Jayanagar, provides comprehensive evaluation and surgical management of obesity using sleeve gastrectomy, Roux-en-Y gastric bypass, and mini gastric bypass, with each procedure selected based on the patient's BMI, diabetes status, reflux history, and surgical risk. His approach combines pre-operative nutritional optimisation, surgical precision, and structured long-term follow-up to support durable weight loss and metabolic improvement.

Determining whether bariatric surgery is appropriate for an individual patient requires a structured multi-disciplinary assessment covering BMI, obesity-related co-morbidities, previous weight management history, psychological readiness, nutritional status, and surgical fitness. Dr Niranjan P provides thorough pre-bariatric surgery patient assessment at NiSH Clinic, Jayanagar, Bengaluru, evaluating each patient against Indian and international eligibility criteria, identifying and optimising modifiable surgical risk factors, and selecting the most appropriate procedure based on the individual's diabetes status, reflux history, BMI, and long-term health goals. His 8,000+ surgical cases and specific bariatric expertise ensure that every patient receives an evidence-based, personalised recommendation before any surgical decision is made.

Obesity is a chronic metabolic condition associated with type 2 diabetes, hypertension, sleep apnoea, fatty liver disease, dyslipidaemia, and joint disease, all of which can be significantly improved or resolved through appropriate bariatric surgery when conservative management has been insufficient. Dr Niranjan P provides surgical management of obesity and its metabolic co-morbidities at NiSH Clinic, Jayanagar, Bengaluru, using laparoscopic sleeve gastrectomy, Roux-en-Y gastric bypass, and other evidence-based bariatric procedures selected based on each patient's specific metabolic profile, diabetes status, and surgical risk. His approach integrates pre-operative optimisation, the appropriate surgical procedure, and structured long-term post-operative follow-up including nutritional monitoring, to achieve durable weight loss and metabolic improvement.

Diabetic foot ulcers arise from the convergence of two complications of diabetes that leave the foot uniquely vulnerable to injury and impaired healing: peripheral neuropathy, which removes the protective pain sensation that would normally alert a person to pressure, injury, or early infection, and peripheral arterial disease, which reduces the oxygenated blood flow that tissues need to repair themselves after injury. A blister from a tight shoe, a small cut, or a heel crack in a person with diabetes can progress to a deep infected ulcer involving subcutaneous tissue, tendon, or bone without the patient experiencing significant pain. By the time the wound is noticed, it has often already progressed beyond what dressings and antibiotics alone can address. Any diabetic foot wound that has not healed within two weeks requires surgical assessment. Dr. Niranjan P, DNB General Surgeon and Consultant General, GI, Laparoscopic, Robotic and Bariatric Surgeon at NiSH Clinic, 4th Block, Jayanagar, Bengaluru, assesses diabetic foot wounds with the clinical priority they warrant. Wound debridement, the surgical removal of all infected, necrotic, and non-viable tissue from the wound, is the central procedure in diabetic foot management. It is performed in the operating theatre under appropriate anaesthesia, allowing systematic assessment of the depth of tissue involvement, whether tendons or bone are affected, and the vascular status of the surrounding tissue. A microbiological swab taken at the time of debridement guides antibiotic selection. Where peripheral arterial disease is contributing to impaired healing, vascular surgery referral is arranged alongside or before debridement, because a clean wound will not heal in a foot that does not have adequate blood supply.

Limb salvage is the guiding surgical principle in diabetic foot management: to preserve as much functional foot and limb as possible while eliminating the infection and achieving durable wound healing. The distinction that determines a patient's long-term functional outcome is not simply whether surgery is needed, but whether surgery is performed early enough to allow a minor intervention rather than a major one. In diabetic foot disease, a minor amputation involves the removal of one or more toes or part of the forefoot, preserving the patient's ability to walk with a prosthetic support or adapted footwear, and carrying far less impact on mobility, quality of life, and cardiovascular outcomes than a major amputation. A below-knee or above-knee amputation, while sometimes necessary and life-saving when infection is uncontrollable or blood supply is inadequate to support healing, is avoided wherever possible because the consequences for the patient's independence and longevity are substantially greater. Dr. Niranjan P, Consultant General and Laparoscopic Surgeon at NiSH Clinic, 4th Block, Jayanagar, Bengaluru, has consistently observed that patients referred early, with a wound that has failed to heal after two weeks of appropriate wound care, have significantly better limb salvage outcomes than patients who arrive after weeks or months of conservative management during which the infection has extended into deeper structures. At that later stage, a wound that might have been managed with debridement and minor amputation may now require resection of larger amounts of tissue or a more proximal amputation to achieve clearance of infected bone and tissue. Early surgical review of a non-healing diabetic foot wound is not an escalation of care: it is the clinically correct response to a wound in a high-risk limb that has not shown evidence of healing within the expected timeframe.
