What is Nutritional Support in Hematology?

Nutritional support in hematology refers to the systematic assessment and management of dietary intake, body composition, and metabolic status in patients with hematologic malignancies, bone marrow failure, and those undergoing hematopoietic stem cell transplantation. It is now considered an integral part of multidisciplinary cancer care.

Patients are at heightened risk of weight loss, sarcopenia, and protein-energy malnutrition due to anorexia, nausea, taste changes, mucositis, graft-versus-host disease of the gut, and prolonged neutropenia. Each of these can independently worsen outcomes and reduce tolerance to curative therapy.

Modern protocols use validated screening tools, indirect calorimetry where available, and stepwise interventions ranging from dietary counseling and oral nutritional supplements to enteral tube feeding and parenteral nutrition for severe gut dysfunction.

Symptoms

Unintentional weight loss greater than five percent in three months
Reduced oral intake from mucositis or nausea
Loss of muscle mass and grip strength
Fatigue and reduced physical performance
Edema or low serum albumin in advanced cases

Risk Factors

Acute leukemia and high-dose induction chemotherapy
Allogeneic stem cell transplantation
Gastrointestinal graft-versus-host disease
Severe mucositis and prolonged neutropenia
Older age, baseline frailty, and prior weight loss

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When weight loss, poor appetite, or swallowing difficulty develop during treatment
  • When oral intake falls below estimated needs for more than a week
  • Before planned high-intensity chemotherapy or transplantation
  • When mucositis, diarrhea, or vomiting limit eating
  • When laboratory tests show falling albumin or other nutritional markers

Treatment Methods

01
Baseline nutrition screening with validated tools
02
Dietitian-led counseling and dietary modification
03
High-protein, energy-dense oral nutritional supplements
04
Enteral tube feeding when oral intake is inadequate
05
Parenteral nutrition for severe gut failure or graft-versus-host disease
06
Micronutrient correction including vitamin D, B12, and iron
07
Monitoring of refeeding risk and metabolic response

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
