“Can excess bleeding during a surgery have an after effect?”

Increased risk for infection and anemia.

I think you meant to say that she had severe bleeding. IF she had severe bleeding, lowering her hemoglobin level below 9, she probably would have needed a transfusion. If not, she will be anemic until her blood is brought back to normal through the normal process in the bone marrow aided by a good diet.

To be clear I am answering if bleeding during surgery can have an affect on the body. Yes. There is usually minimal bleeding during surgery. There are times when he patient's condition can cause bleeding and there are times when a vessel that has not been ligated may cause bleeding. In either case, bleeding can cause decreased oxygen delivery to tissues. This may have several affects such as difficulty breathing, poor wound healing, lethargy, decreased urine output, renal insufficiency, and even chest pain. Some patients may require a blood transfusion after surgery which will likely improve the patient's condition. A patient may require to take iron supplements to help the body to make more blood.

Severe bleeding can cause many problems in the short term but if she survived, in the long term, the body has amazing ability to recover and she should be fine.
