Low blood pressure 80/40 for 42 year female. is 40 for the low blood pressure something to worrie about?

Both r low retake it: Some smaller women will have blood pressures in that range and be ok however, if she is anything but awake, active, alert and feeling fine, CALL 911 and get her to the ER. That includes if she's pale, feels light headed, nauseous, has pulse over 100, a faster pulse standing up than when lying down, has chest pain, shortness of breath, is sleepy, has fever, or has decreased level of consciousness
