Hello,
Since your father is suffering from
vomiting (many times), poor general health condition (getting sick several times), has stomach pain and fainted in the bathroom, you are suggested to get him admitted in a hospital so that he can get medical care and support at the earliest. Vomiting associated with fainting may be indicative of
dehydration, low BP, IBS, GERD,
hypoglycemia, syncope, MI, any developing CAD, stroke, etc.
This is not the time to keep him at home. He needs intravenous fluids and urgent medical aid. To ease stomach pain you can give him antacids. Give him anti emetics, one, SOS to stop vomiting. Give him
liquid diet or semi solid diet like oat, porridge, custard, khichri, etc. Keep him well hydrated and well nourished. He will be recommended to go through certain blood tests,
urinalysis, imaging tests to detect the pathology causing him discomfort. He will be treated accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
