I need GIT diagram for Non systemic therapy of GERD management
A clean medical GIT (Gastroenterology) flowchart diagram titled "Non-Systemic Therapy of GERD Management". The diagram should show a structured flowchart with the following hierarchy: Top box: "GERD DIAGNOSIS (Typical symptoms + Response to therapy)" Arrow down to main branch: "NON-SYSTEMIC THERAPY" Then split into 3 main categories side by side: 1. "LIFESTYLE MODIFICATIONS" (blue box) with sub-bullets: - Weight loss (BMI reduction) - Head of bed elevation (15-20 cm) - Avoid lying down 2-3 hrs after meals - Avoid trigger foods (fatty, spicy, chocolate, coffee, alcohol, citrus) - Smaller, frequent meals - Smoking cessation - Avoid tight clothing 2. "ANTACIDS & ALGINATES" (green box) with sub-bullets: - Antacids (Magnesium/Aluminum hydroxide): Neutralize gastric acid, rapid but short-lived relief, PRN use - Sodium Bicarbonate: Quick relief, avoid in HTN/renal disease - Calcium Carbonate: Acid neutralization + mild antisecretory - Alginates (Gaviscon): Form viscous raft over gastric contents, reduce reflux episodes, physical barrier mechanism 3. "TOPICAL / LOCAL AGENTS" (orange box) with sub-bullets: - Sucralfate: Mucosal protective barrier, binds to ulcer base, less effective for acid suppression - Bismuth compounds: Mucosal coating, mild cytoprotection Bottom note box: "Step-up approach: Start with lifestyle + antacids → Add alginates → Escalate to systemic therapy (H2RA/PPI) if insufficient" Use a white background, clear arrows connecting boxes, color-coded sections, professional medical font style, and well-organized layout with clear readable text.
Non-Systemic Therapy of GERD - Key Points
1. Lifestyle Modifications (First-line for ALL patients)
- Weight loss - reduces intra-abdominal pressure on the LES
- Head of bed elevation (15-20 cm) - especially for nocturnal/supine reflux
- Avoid lying down 2-3 hours after meals
- Dietary triggers to avoid: fatty/spicy foods, chocolate, coffee, alcohol, citrus, mint
- Smaller, more frequent meals
- Smoking cessation - nicotine reduces LES tone
- Avoid tight-fitting clothing - reduces abdominal pressure
2. Antacids
| Agent | Mechanism | Notes |
|---|---|---|
| Mg/Al hydroxide | Acid neutralization | Fast-acting, PRN use |
| Calcium carbonate | Acid neutralization | Mild antisecretory effect |
| Sodium bicarbonate | Rapid neutralization | Avoid in HTN/renal disease |
3. Alginates (e.g., Gaviscon)
- React with gastric acid to form a viscous gel raft that floats on gastric contents
- Physically prevents reflux - a non-systemic barrier mechanism
- Preferred when post-meal reflux is predominant
4. Topical/Mucosal Protectants
- Sucralfate - polymerizes in acid to form a protective barrier over the mucosa; useful in pregnancy
- Bismuth compounds - mucosal coating, mild cytoprotection
