Bilateral foot drop linked to rapid intentional weight loss and long distance walking

Abstract

There are many causes of acute onset foot drop ranging from deep fibular nerve or sciatic nerve injury caused by trauma or a compressive mass such as a neuroma, to spinal cord disorders like disc herniation causing L4-5 radiculopathy, and various muscular dystrophies affecting the tibialis anterior muscle responsible for foot dorsiflexion and eversion. Even brain disorders like MS, stroke or ALS can result in foot drop. We present a case of bilateral foot drop as a complication of rapid 70 lb weight loss which was described in literature previously as “slimmer’s palsy”.
