Internist Questions Overall weakness

Why I am still feeling weak after having my surgery last month?

I had a surgery for my appendix last month, and I'm still feeling really weak. I don't even want to leave the house. What could be the reason for this?

There are many different factors that go into the feelings of weakness and a pos-op situation, so I would discuss this with your surgeon and perhaps there are additional labs that should be looked at, and in the meantime, you should concentrate on proper nutrition, adequate hydration, and getting some additional exercise on a daily basis.
Your sx could be due to any of the following:

1) ANEMIA(which can occur with surgery due to blood loss)

2) INFECTION--incuding post-appendicitis intra-abdominal or liver abscess, urinary tract infection, pneumoina, etc(most of these would likely be associated with concomitant fever and focal sx, but not all the time--especially when the patient is older)

3) HYPERG:LYCEMIA/DIABETES--sometines diabetes or elevated blood sugars can be instigated or exacerbated by infections(like appendicitis) or surgery

4) ANOREXIA and/or REDUCED FLUID INTAKE--if you are not eating/drinking normally for some reason, this can cause dehydration, low blood pressure, ortrhostatic hypotension, weakness and loss of energy, etc

5) Be sure it is not due to some NEW DRUG that YOU MAY HAVE BEEN STARTED ON(ie--anti-hypertersives, antibiotics, etc)

6) also, intercurrent CARDIAC or RENAL insufficiency/failure brought on by infection and/or surgery can cause weakness, fatigue, depression, etc

A good HISTORY and PHYSICAL done by an experienced clinician, and a few simple tests, would usually be able to determine the cause(s) and any necessary treatment.
