Detailed explanation-1: -The most common clinically relevant micronutrient deficiencies after gastric bypass include thiamine, vitamin B₁₂, vitamin D, iron, and copper. Reports of deficiencies of many other nutrients, some with severe clinical manifestations, are relatively sporadic.
Detailed explanation-2: -Ferrous fumarate: The most frequently recommended iron salt, ferrous fumarate has 33% available as elemental iron, plus is easier on the stomach and has higher bioavailability. This is why it’s the most popular supplement for those following bariatric surgery.
Detailed explanation-3: -After bariatric surgery, decreased absorption areas in the small intestine, pancreatic secretion, and changes in bile distribution are the factors that lead to decreased absorption of vitamin D. Vitamin D deficiency is also quite common in morbidly obese patients waiting for bariatric surgery.
