“Previous LSG present” usually means you previously had laparoscopic sleeve gastrectomy (LSG), a weight-loss surgery where much of the stomach is removed to form a narrow sleeve.

In a pregnancy or surgical record, it means the doctor has noted this past operation because it can affect nutrition, medication absorption, reflux, and surgical planning.

It does not mean there is necessarily a current problem. If you share the exact report sentence or context, I can interpret it more precisely.

In an OB-GYN history file, “previous LSG” almost certainly means:

Previous LSCS / LUSCS = previous Lower Segment Caesarean Section
That is, the patient has had a previous C-section delivery, usually through a low transverse uterine incision.

Sometimes handwriting or typing makes LSCS look like LSG. In this context, it is unlikely to mean sleeve gastrectomy.

This matters in the current pregnancy because the clinician will assess the prior operative details and discuss whether a vaginal birth after C-section or a repeat C-section is appropriate.

LSCS means Lower Segment Caesarean Section.

“Previous LSCS present” means the patient has had a previous C-section, usually with a low transverse incision in the lower part of the uterus.
