Zinc Functions Deficiency Management
Presentation · PPTX
The PPT has 10 slides with a deep navy + teal professional medical design. Here is what each slide covers:
| Slide | Content |
|---|---|
| 1 | Title slide - with periodic table element block for Zn |
| 2 | Introduction - key stats (2nd most abundant trace element, >300 enzymes, ~2g body stores) |
| 3 | Functions - 4 cards covering Catalytic, Structural, Regulatory, and Physiological roles |
| 4 | Dietary Sources & Requirements - food sources, absorption inhibitors, RDA table by population group |
| 5 | Causes of Deficiency - Inadequate Intake, Malabsorption, Increased Losses, Increased Requirements |
| 6 | Clinical Features - colour-coded Mild / Moderate / Severe with Acrodermatitis enteropathica note |
| 7 | Diagnosis - serum zinc threshold (<70 µg/dL), additional markers, and 6 diagnostic caveats (albumin, SIRS, pregnancy effects) |
| 8 | Management - 3-step flow: Dietary Modification → Oral Supplementation → Special Situations (AE, TPN, paediatric diarrhoea) |
| 9 | Toxicity & Monitoring - UL (40 mg/day), acute/chronic toxicity, monitoring parameters |
| 10 | Key Takeaways - concise 6-point clinical summary |
