Magnesium deficiency any ideas ?

Most absorption of water and electrolytes occurs in the colon. If you are only 6 months out from a colectomy, your body/remaining digestive tract may still be trying to make up for the loss and adapt. Drinking an electrolyte replacement drink as well as plenty of water is a daily must for me but isn't enough. It took me almost 2 years to get to the point of maintaining hydration on my own - and it's still a struggle at times.

Have you tried magnesium glycinate (NOT magnesium oxide)? It is a supplement (oral) and not an Rx drug - but do ask your doctor about it first. I found I am able to absorb the glycinate form (the mag. oxide often causes intestinal distress - not something we need or want). I am able to maintain a low-normal magnesium level taking the supplement. As for the potassium, calcium, iron, B-12, etc. - your dr. should be able to prescribe meds for these that don't require an infusion - potassium chloride, regular B-12 injections, calcium supplements, etc.

Are you underweight? I also found that when I was finally able to put (and keep) some weight on - 10 pounds or so - that helped significantly. Being dehydrated is miserable...I feel for you. I hope you're able to find a resolution.

Hi Lucky lass - it is rough and sometimes slow going until your body begins to acclimate. Your weight gain (even if it is not much at this point) is a positive indicator. Try to keep up with drinking water, electrolyte replacement drinks and eating as much as you are able - you'll get there !
