What each option means

Acute Stress (multiplies on top of activity)

None (×1.00): Stable outpatient, no acute illness/surgery.
Mild (×1.10): Uncomplicated postop, mild infection, minor trauma.
Moderate (×1.20): Major surgery, sepsis, moderate trauma.
Severe (×1.30): Severe sepsis, large burns, multi‑organ failure.

Chronic Illness (multiplies with acute stress)

None (×1.00): No chronic disease or well‑controlled.
Mild/stable (×1.05): Class I–II CHF, COPD GOLD 1–2, CKD 3a, DM w/o complications.
Moderate (×1.10): Class II–III CHF, COPD GOLD 3, CKD 3b–4, active autoimmune disease on IS.
Severe (×1.15): Class III–IV CHF, COPD GOLD 4, decomp cirrhosis, metastatic cancer on therapy, ESRD on dialysis.

Stoma Type (base stoma factor)

None / Colostomy / Urostomy (×1.00): No inherent calorie increase from the stoma itself.
Ileostomy (×1.05): Faster transit & sodium/water losses; modest calorie bump.
Jejunostomy / Short bowel (×1.30): Significant malabsorption risk; much higher needs.

Output (applied on top of stoma factor)

Normal (×1.00): Ileostomy ~600–1200 mL/day, or typical for your stoma.
High (×1.10): >1500–2000 mL/day (ileostomy) or noticeably increased losses.
Very high (×1.15): >2000 mL/day; risk of dehydration/malnutrition is high.

Goal

Maintenance (×1.00): Maintain current weight.
Weight gain (+10/+20/+30%): Stepwise increases for building weight.
Repletion (×1.15): For illness/malnutrition; conservative default.
Weight loss (–10/–20/–30%): Calorie deficits; avoid during acute illness/high output.

Formula: Target = REE × Activity × (Acute × Chronic) × Stoma × Output × Goal. REE is Mifflin–St Jeor. This tool is educational and not a substitute for clinical judgment.
