Malabsorption

Mahahalagang Punto

• Ang malabsorption ay impaired nutrient uptake sa GI tract at maaaring kasangkot ang isa o maraming nutrient classes.
• Karaniwang clinical patterns ang diarrhea, steatorrhea, bloating, fatigue, flatulence, at hindi sinasadyang weight loss.
• Nagkakaiba-iba ang deficiency manifestations ayon sa nutrient na apektado (halimbawa anemia, night blindness, abnormal bleeding, tetany, neuropathy, at bone weakness).
• Pinagsasama sa evaluation ang broad laboratory screening at targeted stool, breath, endoscopic, at pancreatobiliary diagnostics.
• Mga prayoridad sa nursing ang trend-based assessment, deficiency-risk surveillance, symptom journaling, at patient-family education.

Pathophysiology

Nangyayari ang malabsorption kapag nasisira ang digestive o absorptive processes, kaya hindi epektibong naililipat ang nutrients sa sirkulasyon. Maaari nitong maapektuhan ang proteins, carbohydrates, fats, vitamins, minerals, o trace elements.

Maaaring mangyari ang disruption sa maraming digestion phases at kadalasang kaugnay ng underlying GI o pancreatic disease. Nakadepende ang clinical severity sa lawak ng absorptive dysfunction at sa nutrient classes na apektado.

Sa celiac-pattern disease, sinisira ng gluten-triggered autoimmune injury ang small-intestinal villi, nagdudulot ng mucosal scalloping at nababawasan ang absorptive surface area sa paglipas ng panahon.

Classification

• Luminal phase dysfunction: Hindi sapat ang enzyme- o bile-mediated hydrolysis/solubilization ng nutrients.
• Mucosal phase dysfunction: Mahinang epithelial transport ng digested products mula intestinal lumen papasok sa enterocytes.
• Postabsorptive phase dysfunction: Mahinang transport ng reassembled lipids at nutrients mula enterocytes papunta sa systemic circulation.
• Nutrient-specific deficiency pattern: Isolated vitamin/mineral deficit kumpara sa mixed macro-micronutrient deficits.

Nursing Assessment

NCLEX Focus

Sa pinaghihinalaang malabsorption, i-prioritize ang deficiency-pattern recognition at maagang pagtukoy ng reversible underlying causes.

• Suriin ang symptom cluster: diarrhea, steatorrhea, abdominal bloating/cramping, increased flatulence, fatigue, at weight loss.
• Suriin ang deficiency manifestations ayon sa nutrient pattern (halimbawa anemia, pagbabago sa night vision, ecchymosis/bleeding tendency, tetany, neuropathy, at motor weakness).
• Suriin ang history ng mga disorder na kaugnay ng malabsorption (halimbawa celiac disease, lactose intolerance, pancreatic insufficiency, ulcerative colitis, inflammatory bowel disease, parasitic infection, at Whipple disease).
• Suriin ang objective cues kabilang ang muscle wasting, abdominal distention, ascites, peripheral edema, oral mucosal ulcers, at peripheral neuropathy.
• Suriin ang skin/perfusion at hemodynamic cues kabilang ang pallor at orthostatic hypotension patterns.
• Suriin ang dehydration physiology sa panahon ng active GI losses (tachycardia, hypotension, poor skin turgor).
• Suriin ang neuromuscular hypocalcemia cues kapag present (halimbawa Chvostek o Trousseau signs).
• Suportahan ang ordered testing: CBC, comprehensive metabolic panel, albumin/magnesium/zinc/phosphorus, targeted vitamin levels, fecal-fat studies, jejunal aspirate culture, at carbohydrate breath testing.
• I-coordinate ang cause-directed diagnostics ayon sa order (halimbawa colonoscopy/biopsy, CT para sa pancreatitis contexts, ERCP/MRCP para sa pancreatic insufficiency pathways, at upper endoscopy para sa inflammatory small-bowel disease evaluation).

Nursing Interventions

• Magsagawa ng tuloy-tuloy na symptom at nutrition-status reassessment para maagang matukoy ang progression.
• Tumulong sa ordered diagnostic procedures at magbigay ng procedure-focused patient education.
• Patibayin ang food-and-symptom journaling kabilang ang timing ng meals at onset ng GI symptoms.
• Ituro sa pasyente at caregivers kung paano lumilitaw ang deficiency symptoms at kung kailan dapat i-report ang escalation.
• Magbigay ng emotional support habang isinasagawa ang diagnostic workup at mataas pa ang uncertainty.
• I-coordinate ang interdisciplinary care at diagnostics para matukoy ang etiology at masuportahan ang targeted treatment planning.
• Muling suriin ang hydration, weight trend, at functional status habang nagpapatuloy ang evaluation.
• Suriin ang outcomes gamit ang symptom trend, nutrition adequacy, vital-sign stability, at pagbuti ng vitamin/mineral/electrolyte laboratory values.
• Suportahan ang cause-directed management plans (trigger-food avoidance, supplementation, at procedure/surgery referral kapag indicated), kabilang ang gastroenterology collaboration.
• Kung nagpapatuloy ang nutrient deficits sa kabila ng documented meal-plan at supplement adherence, i-escalate ang reassessment para sa patuloy na absorptive dysfunction at route-adjusted replacement strategies (halimbawa oral to enteral o parenteral pathways per order).
• Ibigay ang ordered vitamin, mineral, at electrolyte replacement; magbigay ng IV fluids kapag may dehydration o hemodynamic instability.

Deficiency Escalation Risk

Ang delayed recognition ng malabsorption ay maaaring humantong sa progressive electrolyte imbalance, micronutrient depletion, at functional decline.

Pharmacology

Drug Class	Examples	Key Nursing Considerations
Deficiency-replacement therapy	Vitamin/mineral replacement regimens	Itugma ang replacement sa identified deficits at i-monitor ang symptom/lab response trends.
Cause-directed GI therapy	Provider-directed etiology-specific regimens	I-coordinate ang administration at monitoring ayon sa na-diagnose na underlying disorder.

Clinical Judgment Application

Clinical Scenario

Isang pasyente ang may persistent greasy stools, abdominal bloating, at hindi sinasadyang weight loss na may lumalalang fatigue.

• Recognize Cues: Steatorrhea-pattern stool change, GI symptoms, at progressive weight decline.
• Analyze Cues: Ipinahihiwatig ng findings ang posibleng malabsorption na may lumalalang nutrient-deficiency burden.
• Prioritize Hypotheses: Agarang prayoridad ang pagkumpirma ng absorptive dysfunction at pagtukoy ng reversible cause.
• Generate Solutions: Simulan ang broad lab panel, stool/breath testing, at targeted imaging/endoscopic workup ayon sa orders.
• Take Action: Simulan ang symptom-intake journaling support, patibayin ang education, at i-coordinate ang interdisciplinary follow-up.
• Evaluate Outcomes: Bumababa ang deficiency burden at GI symptoms habang naipapatupad ang cause-directed therapy.
