Trend Analysis
Five data points showing volatile pattern:
- 2026-03-02: 1.4 mg/dL (L) — first measurement, supplement started thereafter
- 2026-04-20: 1.2 mg/dL (L, nadir) — supplement supply lapsed ~Apr 6; concurrent Na nadir 128
- 2026-04-27: 1.4 mg/dL (L) — partial recovery back to Mar 2 baseline level
- 2026-05-04: 1.6 mg/dL (N) — normalized to lower limit of normal range (1.60–2.60)
- 2026-05-11: 1.5 mg/dL (L) — re-dropped below normal (−0.1 from May 4)
The brief normalization on May 4 was not sustained. By May 11, magnesium re-dropped to 1.5 mg/dL — below the normal range (1.60–2.60). This suggests:
1. Inadequate supplementation dose — current regimen (400 mg TID per May 6 clinic note) is insufficient to achieve sustained normalization
2. Ongoing Mg wasting — azacitidine/venetoclax-related renal losses continue
3. Absorption issues — oral Mg formulation may have poor bioavailability
The May 11 drop coincides with chloride re-dropping from 103 → 96 mmol/L and bicarbonate rising to 29.1 mmol/L (borderline high), suggesting recurrent electrolyte disturbance despite stable sodium (137 mmol/L, still normal). See Chloride, Bicarbonate, Sodium.
KEY CONTEXT (2026-04-20 clinic note): Patient was taking an oral magnesium supplement but ran out approximately 2 weeks before the Apr 20 visit (~2026-04-06). Supplementation was resumed, but current dose (400 mg TID per May 6 note = 1200 mg/day) appears insufficient. Consider dose escalation or IV repletion. See Magnesium Oral.
Magnesium dropped from 1.6 mg/dL (May 4, normal) to 1.5 mg/dL (May 11, low) — back below the normal range (1.60–2.60). The brief May 4 normalization was not sustained. This indicates inadequate oral supplementation (current 1200 mg/day is insufficient) or ongoing chemotherapy-related Mg wasting. Dose escalation or IV repletion may be needed. Hypomagnesemia increases arrhythmia risk, fall risk, and may impair renal Na handling. See Magnesium Oral.
The brief May 4 electrolyte normalization was not sustained. By May 11: Mg re-dropped (1.5, low), Cl re-dropped (96, low), and HCO3 rose to borderline high (29.1). Only Na and K remain normal. This suggests an ongoing electrolyte disturbance pattern requiring intensified Mg supplementation and continued monitoring.
