Ab main aapko basal aur bolus dose ka mukammal jawab Urdu/Roman Urdu mein deta hun, jo medical textbooks se liya gaya hai.
Basal aur Bolus Dose - Mukammal Wazahat
Bunyadi Tasawwur (Basic Concept)
Ek normal insaan ka pancreas din bhar do tarah se insulin release karta hai:
- Continuous (Lagatar) - Background insulin jo hamesha khoon mein rehti hai
- Meal-time (Khane ke waqt) - Jab khana khate hain, pancreas zyada insulin release karta hai
Yeh dono zaroratein poori karne ke liye Basal-Bolus Regimen design kiya gaya hai.
π΅ Basal Dose
| Cheez | Detail |
|---|---|
| Kya hai? | Long-acting insulin jo 24 ghante background coverage deti hai |
| Kab di jaati hai? | Ek ya do baar subah/raat, khane se alag |
| Kaam kya hai? | Fasting mein blood sugar stable rakhna, liver ki glucose release control karna |
| Kitni? | Total daily dose ka 50% |
| Examples | Glargine (Lantus), Detemir (Levemir), Degludec (Tresiba) |
| Action | Koi peak nahin - smooth aur peakless coverage |
Glargine ki Properties:
- Onset: 1.5-2 ghante
- Peak: Peakless (koi peak nahin)
- Duration: 16-24 ghante (Glargine U300: 30-36 ghante, Degludec: 36-40 ghante)
π΄ Bolus Dose (Prandial Dose)
| Cheez | Detail |
|---|---|
| Kya hai? | Short/Rapid-acting insulin jo khane ke waqt di jaati hai |
| Kab di jaati hai? | Har bade khane se 15-30 minute pehle |
| Kaam kya hai? | Khane ke baad blood sugar spike rokna (postprandial control) |
| Kitni? | Total daily dose ka 50% (teen khano mein divide) |
| Examples | Lispro (Humalog), Aspart (NovoRapid), Glulisine (Apidra), Regular insulin |
| Action | Tez onset, short duration |
Rapid-Acting Insulin ki Properties:
- Onset: 15-30 minute
- Peak: 30-90 minute
- Duration: 3-4 ghante
Bolus Dose Calculate Kaise Karte Hain?
Bolus dose 2 cheezoon se milti hai:
1. Carbohydrate Coverage (Khane ka hisaab)
- Carbohydrate-to-Insulin Ratio (CIR): Aksar 1 unit per 10-15g carbohydrate
- Example: Aapne 60g carbs khaye β 60 Γ· 15 = 4 units
2. Correction Factor (Agar sugar high ho)
- 1 unit se blood sugar 20-50 mg/dL neeche aati hai
- Example: Khane se pehle sugar 220 mg/dL hai, target 100 mg/dL β extra (220-100) Γ· 50 = 2.4 units correction
- Total Bolus = Carb coverage + Correction dose
Total Daily Dose (TDD) kaise nikalni hai?
0.3 to 1.0 unit/kg/day - phir:
- 50% = Basal (ek ya do baar)
- 50% = Bolus (teen khano mein distribute)
Example: 70 kg ka marz (0.5 unit/kg) = 35 units/day
- Basal: 17-18 units Glargine raat ko
- Bolus: ~6 units har khane se pehle
Insulin Stacking se Bachein!
Rapid-acting insulin ka asar 6 ghante tak rehta hai. Agar patient 2 ghante baad dobara dose le, toh pehli dose ka 64% abhi bhi active hai. Is se hypoglycemia ho sakta hai - is ko "insulin stacking" kehte hain.
Mukhtasar Faraq
| Basal | Bolus | |
|---|---|---|
| Type | Long-acting | Rapid/Short-acting |
| Timing | Subah ya raat | Har khane se pehle |
| Dose | Total ka 50% | Total ka 50% |
| Kaam | Background control | Meal spike control |
| Peak | Peakless | Haan, tez peak hai |
| Example | Glargine, Detemir | Lispro, Aspart |
Clinical Note: Yeh regimen (Multiple Daily Injection - MDI) Type 1 Diabetes ke liye zaroor lagayi jaati hai. Type 2 Diabetes mein pehle basal insulin shuru ki jaati hai, phir zaroorat pari to bolus add hoti hai.
