Drugs.com explains that magnesium citrate works by retaining water in the intestine, causing the bowels to evacuate. It should be taken on an empty stomach and can react poorly with other medications, which is why it should only be taken under medical supervision. Follow the magnesium citrate solution with a full glass of water. Do not take the recommended dose for more than one week. It can also cause stomach discomfort and diarrhea.
Laxative abuse is very dangerous and can cause long-term health complications, according to the National Eating Disorders Association. Food and calories are chiefly absorbed in the small intestine, and by the time the laxative is able to work on the large intestine, there are very few nutrients left to be evacuated. Frequent laxative use upsets the balance of electrolytes and minerals, causing improper functioning of vital organs. Over time the body becomes dependent on laxatives and requires larger and larger doses.Learn more about Vitamins & Supplements
