[|Human|] For the past 3 days I have had a fullness and pain in my lower abdomen.  I have no appetite before mid-afternoon.  Simply seem to disappear by 7-8PM.  My guess was a bladder infection, but no pain with urination.  I am a 34 year old female and am positive I am not pregnant.
[|AI|]  HI. The causes of Fullness and Pain in Lower Abdomen with loss of appetite can be due to Enteritis, Typhoid, and such problems of the intestine. This is a natural process when there is intestinal infection or affection of whatever reason, the first thing the body responds by loss of appetite, This is a natural protective mechanism. I would advise the blood tests _ CBC, tidal for typhoid, culture and sensitivity of the blood for typhoid, liver functions as hepatitis is one of the important reasons for loss of appetite. Ultrasonography if required by the Doctor who would examine you and prescribe you the proper treatment. This can not really occur due to Urinary Bladder infections
