Causes

Mechanism

Nos-systemic causes of meralgia paresthetica

· Sequels of surgery

· Direct mechanical compression of the nerve

· Sequels of surgery: Orthopedist surgeries involving the pelvis may damage the nerve due to anatomical variations.

· Direct mechanical compression of the nerve: Occurs by increased intrabdominal pressure by pregnancy, obesity and masses in the pelvic/abdominal cavity.

Systemic causes of meralgia paresthetica

· COVID-19

· Diabetes mellitus (DM)

· Vasculitis

· COVID-19: MP developed by neurological sequels, low mobilization and also to an increased inflammatory state and the consequent pain of the ICU patient.

· Diabetes mellitus (DM): MP occurs due to peripheral neuropathy which leads to edema and oxidant damage and imbalance in the Na/K pump.

· Vasculitis: Related to DM and associated with endothelial dysfunction/peripheral arterial disease.
