Hi,
Noted the history about your son undergoing 3
Hiatus Hernia surgery, uncontrollable nausea, retching, heaves
lightheadedness and
dizziness, not sure about the origin/cause of such symptoms.
Hiatus hernia is a specialized surgery and the results are variable as the type of surgery includes closing hte hernia defect in the diaphragm and rotation of upper part of stomach around esophagus.
This can make things pretty tight after development of fibrosis as a natural process of healing and so on.
Hence the retching and nausea can be explained wtih such a procedure.
Other symptoms such as lightheadedness, dizziness and
profuse sweating can be secondary to the first effects and surgery or can have different cause altogether.
Hence I would advise you to take him to the PCP and get a clinical evaluation, examination and investigations to see for other causes like any close cavity infection, typhoid, malaria or so on.
Additional investigations like X-ray Chest,
Ultrasonography, CT scan of abdomen and Upper GI Endoscopy will help further to find or rule out other causes.
Once the cause is found treatment may be easy.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
