This topic is about managing persistent magnesium deficiency, particularly for someone with an ileostomy and high output. The person sharing their experience is a 71-year-old who has been dealing with low magnesium levels, known as hypomagnesaemia, which has required frequent hospital visits for intravenous magnesium infusions. These infusions have been challenging for their mental health, and they are seeking practical alternatives. Here are some insights and advice that might help:

1. Oral Magnesium Supplements: Consider magnesium gluconate, taking 500 mg tablets twice in the morning and twice in the evening, totaling 2 grams per day. These are available over-the-counter or can be ordered in bulk from a pharmacy. It's important to monitor magnesium levels with a healthcare provider.

2. Sublingual Magnesium: Try "ionic" or "angstrom" magnesium drops that are absorbed under the tongue. This method bypasses the gastrointestinal tract, potentially reducing stoma output.

3. Transdermal Magnesium:
- Continue with nightly foot baths using magnesium flakes, as this is already part of the current routine.
- Use Mg 12 spray, which is oil-based. Apply it to the inner wrists or behind the knees and rub it in. This has been reported to help with cramps and thicken stoma output.

4. Dietary and Hydration Strategies: Increase the intake of magnesium-rich foods. At the first sign of cramping, drink a full glass of water. This approach is considered cheaper and gentler than pills, with faster absorption in the stomach and upper intestines.

5. Prescription Options and Monitored Therapy:
- MagOx (magnesium oxide) can be taken daily under the supervision of a nephrologist. It has helped another person with high-output ostomy avoid IV infusions since April.
- Monthly magnesium injections are an option if IV access is difficult. Discuss this with a physician.

6. General Guidance: Regular blood work is crucial, with some people having it done every two weeks. It's important to work closely with a trusted doctor, especially if there are concerns about kidney function.
