What Is Protein-Calorie Malnutrition?
Protein-calorie malnutrition (PCM) occurs when your body doesn't get enough protein and calories to maintain muscle strength, support immune function, and promote healing. Without adequate nutrition, you may feel weak, tire easily, and become more prone to infections. If left untreated, PCM can lead to serious health complications.
Common Causes and Risk Factors
Poor appetite or trouble swallowing
Long-term illnesses such as cancer or kidney disease
Digestive disorders that impair nutrient absorption
Advanced age, isolation, or living alone
Economic challenges that limit access to healthy food
Signs and Symptoms
Rapid weight loss or persistently low body weight
Muscle weakness and overall fatigue
Fluid retention causing swelling in the legs or abdomen
Dry, brittle hair and fragile, thin skin
Slow wound healing
Frequent infections or slow recovery from illness
How Dr. Nghia Nguyen Diagnoses Protein-Calorie Malnutrition?
Dr. Nguyen uses a step-by-step approach:
Medical & Nutritional History
She reviews your recent weight changes, appetite, dietary habits, underlying illnesses and the character of your epigastric pain (onset, duration, triggers).
Physical Examination
Dr. Nguyen assesses muscle mass, grip strength, body weight and conducts a focused abdominal exam—checking for tenderness or swelling in the epigastric region.
Laboratory Tests
Serum proteins: albumin, prealbumin and total protein
Vitamin & mineral panels: including B12, iron studies, calcium and magnesium
Complete blood count and comprehensive metabolic panel to rule out infection or organ dysfunction
Imaging & Endoscopic Studies
Abdominal ultrasound or CT scan to evaluate digestive organs and detect muscle wasting
Upper endoscopy (EGD) to inspect the esophagus, stomach and duodenum for ulcers or inflammation causing epigastric pain
Nutritional & Functional Assessments
When needed, he orders bioelectrical impedance analysis (BIA) or DEXA scans to quantify lean body mass and guide personalized nutrition plans.
Advanced Diagnostics (if needed)
In complex cases of malabsorption or persistent pain, Dr. Nguyen may recommend small-bowel series, motility studies or targeted biopsies to identify underlying pathology.

Frequently Asked Questions
What is the ICD-10 code for PCM?
Protein-calorie malnutrition is coded as E44.x for general PCM and E43 for severe PCM.
How long does recovery take?
Most people notice improvements in strength and weight within 4-8 weeks of starting treatment.
Can children develop PCM?
Yes. PCM can affect kids, especially those with poor diets, chronic illness, or absorption issues.
Is PCM the same as cachexia?
No. Cachexia is a muscle-wasting syndrome tied to illness. PCM is due to inadequate protein and calorie intake.
Will I need a feeding tube?
Only if oral intake isn't sufficient. Dr. Nguyen will review all options and guide you through the process.
Are nutrition supplements covered by insurance?
Many supplements are covered. Our team can help you verify your benefits and find cost-effective solutions.
