- Mechanism
- Mineralocorticoid receptor activation → sodium reabsorption at distal tubule
- Osmotic extracellular fluid shift from high sodium intake
- Loop diuretics block Na-K-2Cl transporter in thick ascending limb
- MK-677 retention is endocrine, not dietary. Requires potassium-sparing strategy
- Onset Timeline
- 7–14 days after starting MK-677
- 4–12 hours after high-sodium meal
- Diuresis begins 30–90 minutes after administration
- Aldosterone-driven retention builds gradually; dietary bloat is acute
- Peak Severity
- Week 2–4 of continuous MK-677 use
- Peaks 6–8 hours post-meal, resolves within 24–48 hours
- Depends on diuretic class and dose
- MK-677 retention worsens over weeks before stabilising. Patience required
- Resolution Without Intervention
- Partial resolution by week 6–8 due to homeostatic adaptation
- Resolves spontaneously as sodium is excreted
- N/A. Diuretics are the intervention
- Body adapts to elevated aldosterone; retention decreases 40–50% from peak by week 8
- Potassium Impact
- Potassium supplementation 2–4g/day reduces retention 40–60%
- No meaningful effect on dietary bloat
- Loop diuretics cause potassium wasting; requires supplementation
- Potassium is the single most effective non-pharmaceutical intervention for MK-677 bloating
