Hi,
All the symptoms can be due to one of the following reasons:
Infection still lingering somewhere which needs careful evaluation.
Some other problem secondary to or unrelated to surgery.
Deficiency of vitamins, mineral, trace elements or
anemia and so on.
All this can be diagnosed by the following ways:
Get admitted for proper clinical evaluation, examination by a Surgeon and Physician too.
Get full investigations as follows:
Blood: CBC, culture and sensitivity, all organ functions like
thyroid,
liver, kidneys and so on.
X-ray of chest.
Ultrasonography or better a
CT scan of abdomen.
All these can get you a proper diagnosis.
Specific the cause can be treated well for you to recover well.
Also take therapeutic doses of multivitamins, mineral, trace elements, proteins and iron.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant, General Surgeon
