My mother has been feeling unwell since this afternoon. She has fever, cold, vomits after consuming anything, including ORS, milk, idli, or buttermilk. Our family doctor has prescribed Dolo, Zerodol, Montair LC, and administered an Ondem injection. However, she continues to vomit after eating or drinking. She has a known history of acute gastritis and IBS. Currently, she is experiencing continuous burping after eating. The doctor mentioned starting IV fluids tomorrow. Given her symptoms and the fact that she’s unable to retain food or fluids, what else can be done at this point? What could be the underlying cause? Does she need immediate hospitalisation? she has been the sole caregiver for my 83-year-old grandfather over the past four days, who is currently suffering from pneumonia. This might have caused physical or emotional strain.
