Micronutrients & recovery
Bariatric surgery leads to long-term nutrient deficiencies (anemia, neuropathies, osteoporosis) due to malabsorption and reduced gastric acid, requiring lifelong monitoring and supplementation.
After bariatric surgery, you must take lifelong vitamin and mineral supplements to prevent anemia, nerve damage, and bone loss. This is especially critical if you had a bypass procedure.
StrongQualifiesHIGH confidence
In general, mainly malabsorptive procedures, e.g., bypass procedures with duodenal exclusion of nutrients and a concomitant decrease in gastric acid, will have a higher risk of micronutrient and macronutrient deficiencies. Consequently, BS patients are at higher risk of developing nutrient deficiency-related disorders such as anemia, certain types of neuropathies or osteoporosis
Why this rating
The paper cites multiple studies (22, 23) linking BS to specific nutrient deficiencies.
