Do Sweat the Small Stuff

A 50 year old patient with hypertension, diabetes, arthritis, and obesity gets the procedure shown above. Six months after the procedure, he is doing well; he no longer needs antihypertensives or insulin; he only takes some metformin and vicodin. The surgeons say he can go back to his regular family doctor so he shows up at your office. His only complaints are a new numbness and tingling at the tips of his fingers and toes. His laboratory studies show a microcytic anemia.

Challenge: What is the cause of these signs and symptoms?

Do Sweat the Small Stuff

After a Roux-en-Y Gastric Bypass, micronutrient deficiencies are common. Peripheral neuropathy is seen with vitamin B12 deficiency (due to bypassing the majority of the stomach). Anemia is seen with iron deficiency (due to reduced acid and bypassing the duodenum and proximal jejunum).

Pregnant woman lose a lot of iron and folic acid daily to help with her baby growth and development which makes her more likely to suffer from anemia during pregnancy. Read this article to learn the types, causes and treatment of the common types of anemia during pregnancy.
