Girlfriend has stomach pain below rib with lump. has had diareah/constipation constantly for the past year. has often nausea and has been committing?

Don't know what: Lump is but her symptoms are typical of impaired function in the lower brain. This is a common effect of poor diet, especially sugar that easily produces vitamin b and magnesium deficiency.

A change in bowel: Habitus x 1 year means that medical assessment is over due. She can start with her primary physician (who may or may not need to refer for consultation with a specialist).
