Sleeve Gastrectomy. Is it safe to use magnesium citrate?

It is safe to use it after surgery.  However, I normally do not have my patients use any laxatives before surgery.  Laxatives tend to dehydrate you and studies have shown an increase in DVT (blood clots) from laxative use prior to surgery.  There is no need to clear you bowel prior to the gastric sleeve.

Yes, prior to surgery there is no contraindication to use it. After surgery we have to be more careful because the use of laxatives can lead to dehydration, something that can lead to serious complications in a bariatric patient. Before using it, consult with your surgeon and the nutritionist who is handling your case.

Yes, Its safe to use it.
In my practice we routinely use Magnesium Citrate prior to Gastric Sleeve.
Not only it clears your Bowel, It also reduces constipation, which can be due to Narcotics use after surgery.
Also Magnesium Citrate can be used after surgery. You need to be careful, as it can cause dehydration, so we recommend more gentle agents and emphasis on increasing fluid intake.
