Fortis Hospital & Kidney Institute
Kolkata
Dr. Himangshu Nagar is an experienced medical professional associated with Fortis Hospital & Kidney Institute, Kolkata, where he serves as Principal Medical Officer in Nephrology. The official Fortis Healthcare profile lists 28 years of experience. His clinical practice focuses on kidney diseases, diabetes-related health complications and the medical management of conditions affecting renal function.
Dr. Himangshu Nagar holds an MBBS and a postgraduate diploma in Health Science in Diabetology, as documented by Fortis Healthcare. His professional background combines nephrology-related clinical care with diabetes management. He has been associated with Fortis Hospital & Kidney Institute since May 1999, according to his hospital biography.
His documented areas of expertise include chronic kidney disease, acute kidney injury and diabetic kidney disease. These conditions may affect the kidneys' ability to remove waste products, regulate fluid balance and maintain normal electrolyte levels. Clinical evaluation often involves kidney function tests, urine investigations, blood pressure measurements and appropriate imaging.
Dr. Nagar also has a clinical interest in managing diabetes and hypertension, two important risk factors for kidney damage. Long-term care may include glucose monitoring, blood pressure control, medication review and assessment of kidney function. Early recognition of complications can support timely medical intervention and reduce the risk of progressive kidney impairment.
His reported nephrology interests additionally include dialysis care, electrolyte abnormalities, nephrotic syndrome and medical management of selected kidney-related conditions. Patients with advanced kidney disease may require assessment for renal replacement therapy or specialised care. Treatment decisions depend on kidney function, symptoms, overall medical condition and individual treatment requirements.
Fortis Healthcare reports that Dr. Himangshu Nagar has received 18 awards during his professional career, although the individual award names and dates are not specified. Patients seeking consultation for kidney disease, diabetes-related renal complications, hypertension or abnormal kidney function tests in Kolkata can enquire through Fortis Hospital & Kidney Institute, Gariahat, subject to appointment availability.
Chronic kidney disease occurs when kidney structure or function remains abnormal for at least three months. Common causes include diabetes and hypertension. Management involves monitoring kidney function, controlling underlying medical conditions, reviewing medications and recommending suitable lifestyle changes. Treatment aims to slow disease progression and reduce complications.
Acute kidney injury is a sudden reduction in kidney function that may occur because of dehydration, infections, medication effects or serious illness. Assessment includes blood tests, urine investigations and evaluation of possible causes. Treatment focuses on correcting reversible problems, monitoring fluid and electrolyte balance and providing renal support when necessary.
Diabetic kidney disease develops when diabetes damages the kidneys over time. It may initially cause increased urinary albumin and later reduce kidney filtration. Management involves controlling blood glucose, monitoring blood pressure, using appropriate kidney-protective medication and regularly assessing kidney function to reduce the risk of complications.
Diabetes mellitus is a chronic metabolic disorder characterised by elevated blood glucose levels. Poorly controlled diabetes may affect the kidneys, eyes, nerves and cardiovascular system. Treatment involves individualised medication, nutritional guidance, physical activity, glucose monitoring and screening for complications, including diabetic kidney disease.
High blood pressure can gradually damage kidney blood vessels and reduce filtration capacity. Kidney disease may also contribute to difficult-to-control hypertension. Treatment includes regular blood pressure monitoring, appropriate medication, dietary recommendations and assessment of kidney function and urinary protein to reduce long-term cardiovascular and renal risks.
Dialysis helps remove excess fluid and waste products when kidney function becomes severely impaired. Nephrology care includes assessing whether dialysis is required, selecting an appropriate treatment approach and monitoring patients for complications. Management considers blood pressure, fluid balance, electrolytes and individual medical needs.
Haemodialysis removes waste products and excess fluid from the blood using a specialised dialysis machine and filter. It may be necessary for advanced kidney failure or selected acute conditions. Treatment requires suitable vascular access, individually prescribed sessions and monitoring of blood pressure, fluid balance and laboratory results.
The kidneys regulate important electrolytes such as sodium, potassium and bicarbonate. Kidney dysfunction can cause electrolyte abnormalities that affect muscle activity, heart rhythm and overall health. Assessment involves blood investigations, medication review and evaluation of underlying causes. Treatment must correct abnormalities safely and appropriately.
Nephrotic syndrome is characterised by significant protein loss through the urine, often accompanied by swelling and low blood albumin levels. It can result from different kidney diseases. Evaluation includes urine testing, blood investigations and sometimes kidney biopsy. Treatment focuses on the underlying cause and associated complications.
Glomerular diseases affect the kidney's filtering units and may cause blood or protein in the urine, swelling and reduced kidney function. Diagnosis may require laboratory testing, imaging and kidney biopsy in selected cases. Treatment depends on the specific disease and may include medication and long-term monitoring.
Urinary tract infections may affect the bladder, ureters or kidneys and can cause painful urination, fever, urgency or flank discomfort. Assessment considers symptoms, urine testing and underlying risk factors. Treatment depends on infection severity and may include appropriate antibiotics and investigation of recurrent or complicated infections.
Kidney stones are hard mineral deposits that form in the urinary system and may cause severe flank pain, blood in the urine or urinary obstruction. Medical management includes pain assessment, hydration guidance and evaluation of stone-related risk factors. Large or complicated stones may require urological intervention.
Proteinuria occurs when an abnormal amount of protein passes into the urine. Albuminuria is an important early marker of kidney damage, particularly in diabetes and hypertension. Evaluation includes urine measurements and kidney function tests. Treatment focuses on identifying the underlying cause and preserving renal function.
Elevated blood creatinine can indicate reduced kidney filtration, although interpretation depends on age, muscle mass and other factors. Assessment may include estimated glomerular filtration rate, urine tests and review of previous results. Treatment is determined by the underlying cause and the severity of kidney dysfunction.
Fluid retention may cause swelling of the feet, ankles, legs or face. Kidney disease is one possible cause, alongside certain cardiac and liver conditions. Evaluation includes medical examination and appropriate investigations. Management may involve dietary adjustments, prescribed medication and monitoring of kidney function and fluid balance.
Kidney transplantation may be considered for eligible patients with advanced kidney failure. Medical evaluation includes assessment of kidney disease, associated health conditions and transplant suitability. Nephrologists may participate in referral, pre-transplant assessment and long-term post-transplant monitoring alongside specialised transplant teams.
